The silage slump

Submitted by aeadmin on Fri, 09/08/2017 - 00:00

In “The corn conundrum,” we looked at some of the causes of the dreaded “fall slump.” Now we will look at some of the ways to prevent the slump as well as tools to help diagnose it.

Dry matter at harvest

We all know the importance of proper dry matter at harvest. Checking whole plant dry matter for each field is a good first step to having the correct dry matter at harvest.

Chopping too early can lower the starch content of the corn silage and impede fermentation, which can also contribute to the environmental issue of leachate. On the other hand, chopping too late (>40 percent dry matter) can lead to a separate set of problems, such as mycotoxins, poor fermentation, yeast production, decreased starch digestibility and a longer window for total starch digestion.

If we monitor the seven-hour starch digestibility and ammonia levels of fresh corn silage, it can tell us a lot about how the corn is fermenting. Typically, fall corn silage will be low in both the seven-hour starch and ammonia. As the silage ferments over 240 days, the ammonia levels rise and the starch digestibility increases.

Silage inoculants and crop quality

We know that inoculants can speed up fermentation and lower pH, thus saving energy for the cow. Inoculants enable us to get into the piles, bags, bunkers and silos even faster than before.

Future outlook is strong is this area. Work is being done on combinations of inoculants and enzymes to assist in both starch digestion and fiber digestion, which will serve to further our efficiencies.

Inoculants can cater to front end fermentation or feed out protection. Cater your inoculant to your individual situation.

Inoculants coupled with a quality mold inhibitor can be the ultimate line of defense against molds, top spoilage and stability issues. Mold-Zap®, a buffered propionic acid, has been the gold standard in alleviating seasonal total mixed ration heating, but very keen dairymen also use it for preventing top spoilage in bunkers, drive over piles and on silage faces.

Corn Silage Processing Score

Shredlage, a new corn harvesting method for silage, is gaining acceptance. Most importantly, shredlage processing has led to a renewed interest in proper corn silage kernel processing with the choppers many producers already have. With proper corn silage processing, the kernels can be processed down to the new standard of ¼” kernels.

The Corn Silage Processing Score (CSPS) is a great testing tool that is run at virtually all the forage labs in the U.S. because it will assess how well the corn silage has been processed. A Corn Silage Processing Score in the 40–60 percent range is common in unprocessed corn silage and can equate to lost milk. Setting a goal of achieving a processing score above 70 percent will help you reduce the corn silage slump and the impacts it has on your herd.

Before we get CSPS numbers back, is there another way to know if we are correctly processing the corn silage? A new technique involving “floating” fresh corn silage is getting some attention, and it’s easy to find articles and images of the procedure online. The process is very simple and can be accomplished in the field, right at the chopper, but you will need a sample of fresh corn silage, a 5-gallon bucket and some water.

  1. Fill the 5-gallon bucket three-quarters full with water.
  2. Take a 32-ounce cup of fresh corn silage and pour it into the bucket of water.
  3. Stir it around for a few minutes.
  4. Sift out the fiber particles that float to the top.
  5. Dump the water and be sure to save the kernels.
  6. Inspect the kernels to ensure that most of the kernels are quartered. The old concept of “nicked” kernels being sufficient is now antiquated advice.

Monitor the back end

It is a dirty job, but someone really does have to do it. Manure can tell you a lot about how things are working inside the cow.

It’s worthwhile to consider a couple of tools that have been around for a few years.

The Penn State Particle Separator has been used for years to monitor fiber levels in the diet. The particle separator’s “messy” cousin, the manure screen, can tell you just as much, if not more. The true value of manure screening is monitoring over time and with ration changes. With the transition to new crop corn silage, you can see the impact of the new feed. Many times with new crop corn silage, you will see the kernel remnants in the middle screen and fiber changes in the various screens. Benchmarking your manure screens is a great approach because it will enable you to see what the rumen is doing and you can make ration adjustments quicker than if you use a paper-only approach.

While we are messing around with the manure, there is yet another tool that is underutilized, and that tool is fecal starch. Fecal starch testing is done at most commercial feed labs and can tell you a lot about kernel processing and starch digestion, so it can help you to confirm your CSPS scores and the level of starch digestion. Your goal should be to keep the fecal starch under 3 percent, even though you can commonly see the levels initially rise with new crop corn silage samples.

Aiding in the new crop silage transition

Some of the undigested corn can bypass the rumen and cause hindgut fermentation, which can lead to indigestion and rumen upset. The starch-digesting enzyme Amaize® and certain strains of Saccharomyces cerevisiae can assist in breaking down starch and maintaining a proper rumen environment.

Additionally, we know that soluble protein and ammonia levels are at lower levels in fresh corn silage. Products that assist in adjusting the rumen degradable protein levels can help jumpstart the rumen microbial production and assist in starch and fiber digestion. Optigen® can help fuel the rumen in the absence of good new crop soluble protein and ammonia levels.

Don’t feed it, but if you must…

Ultimately, the best way to reduce the fall corn silage slump is not to feed it. It may be frustrating to receive that advice, but it remains true. Starch digestion is often slow, and new crop corn silage should be given three months to properly ferment. Obviously, the longer the fermentation, the better, but there should be a plan in place to have a few months’ carryover of your corn silage crop.

When we must feed fresh corn silages, the tools discussed above can help to reduce the corn silage slump. Ask your local Alltech representative for more information on how we can help you to reduce the new crop corn silage blues.

Futuristic Fido: Tech that's reinventing the pet world

Submitted by aeadmin on Mon, 09/04/2017 - 00:00

The first animals to be domesticated by humans were wolves, although the jury is still out on when exactly this occurred. Now a menagerie of animals is considered companion animals or pets, from the fuzzy chinchilla to the majestic horse. The original reasons for domestication were as varied as the species themselves: protection, hunting, travel and companionship.

Today, pets are considered by their owners to be members of the family. They have their own toys, a special place on the sofa or even their own room.

According to the U.S. Bureau of Labor Statistics, Americans individually spent an average of $500 on their pets for a collective total of $66.75 billion, three times more than 20 years earlier. Their growth in spending is being outpaced by China, where pet lovers are estimated to spend 50 percent more by 2019. With a human population 4.5 times larger than the U.S., this may soon become the world’s biggest market. The European pet industry is also fairly substantial and, according to EuroDev, is expected to grow to $36.4 billion USD by the end of 2017, with the biggest markets being France (16.5 percent), Germany (16 percent) and the U.K. (15.3 percent).

As the population increases, the middle class grows and new geographic markets develop, opportunities abound in the pet sector. Additionally, advances in technology that have been disrupting many other industries are certain to have an effect. Traditional pet products and emerging technologies are converging, opening up never-before-seen opportunities.

Following the eight digital technologies framework* I’ve used in previous blogs, what could disrupt the companion animal market?

1. 3D appendages?

3D printing can offer veterinarians novel life-saving techniques for pets. 3D Systems has partnered with Rita Leibinger Medical to create and print titanium orthopedic knee implants for dogs. They have reported nearly 10,000 successful implants using a procedure they call tibial tuberosity advancement (TTA). TTA eliminates the need for a veterinarian to repair the ligament because it stabilizes the joint using a titanium implant, which speeds up both the surgery itself and the animal’s recovery time.

While it may sound expensive, TTA actually costs significantly less than traditionally hand-built prosthetics. There are many incredible tales of second chances — a duck with a new silicone foot, a cat’s knee implant and a pup’s prosthetic legs. Though not designed solely for animal and veterinary use, several companies have now created prosthetics for animals: NovaCopy, Stratasys, MakerBot, 3dyn and BTech.

2. Are robotic dogs man’s new BFF?

Move over, Fido, man’s new best friend is…a robot? Robotic “Rover” has certainly done well in Japan, where Aibo (Sony) engineered a robotic dog in 1999 that was designed to learn about its owners and to react appropriately to their emotions. These robots used both sensors and artificial intelligence to create such a real impression. In fact, so genuine was the appearance that owners in Japan were holding funerals when their pets “died.”

While this original design was for fun and companion purposes, there seems to be an opportunity to create robotic dogs to replace some of the service animals we have today. Japanese company NSK created Lightbot, a guide robot of sorts, but the design leaves much to be desired when compared to a snuggly pup! Alternatively, robotic dogs or cats could be an ideal solution for families with severe allergies that are prohibitive to real animals.

MiRo is a programmable robotic canine created by Consequential Robotics that has sensors for detecting its surroundings, facial recognition technology and is designed to be emotionally engaging. MiRo won the Best Demonstration Award at the 2017 Human-Robot Interaction conference in Vienna, Austria.

CHiP, made by WowWee, is an intelligent, affectionate robot dog. Using smart technology and advanced sensors, your responses will determine CHiP’s behavior. Cozmo is yet another example.

There is also a robotic company that designs robots resembling animal-like frames called Boston Dynamics. Though these robots are intended less for companion purposes and more for practical applications, they are designed to learn and adapt to their environment. Once you watch a video of their robot, Spot, it’s hard not to imagine how it could easily segue into the pet world with just a little “prettying” up.

3. Drones for lost doggies

There are some practical applications for drones in the pet industry. For one, a drone is capable of searching and finding missing pets. They are able to cover a wider area than a human could and, when combined with other technologies such as the GPS wearables discussed below, could zoom in on the lost animal. Drones have already been used to track and count strays in urban areas such as Houston, Texas. The World Animal Awareness Society used drones to film strays to increase awareness and compassion for the issue.

A few months ago, IBM filed a patent for a drone that could act as a pet sitter or trainer, providing your dog or cat with constant monitoring while you’re away at work. It could train your pet or provide entertainment should your dog get restless or lonely. Potentially, the drone could allow the dog in or out, and also dole out food or treats at mealtimes or for training purposes.

Netherlands-based Tinki.nl thinks the 100 million kilos of dog droppings that are neglectfully distributed in his country create quite the nightmare. Teaming up with Space53, the companies use a drone equipped with thermal imaging and recognition software to locate the mess and apply GPS coordinates to its location. Then, a robot receives the coordinates and cleans the area. It's an incredible way to combine technologies to address a real problem.

4. Sensors for Spot

Sensors for pets, particularly in the form of wearables such as GPS-enabled collars, have seen significant growth over the last few years.

WonderWoof BowTie is a dog activity tracker that can set daily recommended activity targets for your pet based on size, breed and age. It records movement and sends owners progress reports (or reminders to get the dog to be more active!) via an app.

The Buddy by Squeaker glow-in-the-dark LED collar takes this a step further, using GPS and Bluetooth technology to track and organize daily activity. Not only does it use geofencing and real-time tracking, but it will also determine your dog’s temperature and set the thermostat in your home to make your pet more comfortable. It is waterproof and connects to your smartphone for real-time health analysis and updates.

PetPace, designed for dogs or cats, monitors health and alerts owners when something is wrong. Other examples of health monitoring devices include the iotatracker, FitBark and Tailio for cats.

What about fish? FishBit monitors your aquarium, including temperature and fish/coral/plant stock, and it reminds you when the water needs to be changed, all through an app on your smartphone.

Wearables offering GPS monitoring include PawTrack, specifically for cats, Whistle for dogs and Tractive for both dogs and cats. Petkit not only offers a wearable that monitors activity and food intake, but also assesses an animal’s mood, and so does DogStart’s TailTalk. PawTracker is also designed for both dogs and cats and uses GPS locating to keep track of your pet.

However, sensors go beyond wearables. Tired of scooping kitty litter? Litter-Robot has a space-age-looking enclosed litter “box” that senses when your cat is done and cleans the box for you. It also alerts you when the box is full so all you have to do is dump the drawer.

Perhaps the most practical opportunity for sensor technology is in automatic feeders. PetNet makes an automatic feeder that gauges the amount of existing food and reorders more if levels run low. CatFi does much the same, and also uses 3D facial recognition to track how much each individual cat is eating.

Designed by animal-loving neurosurgeons, CleverPet is an automatic feeding system that is also designed to engage and challenge your pet to ease boredom. OurPets Wonder Bowl is paired with a collar tag that allows only the animal it is connected with to eat, which is great for people with more than one pet or animals on special diets. Eyenimal offers a wide range of products, from invisible fencing to no-bark collars, cameras and automatic feeding devices. PetSafe offers all manner of pet products, including food dispensers, automatic ball launchers, electronic pet doors, laser toys for cats and more.

There is no shortage of variety of sensor applications. Most of these are wearables in the form of collars, some are feeders or toys. Almost all will connect to your smartphone, where appropriate.

Astro: Garmin’s handheld tracking system

Catspad: Programmable automatic cat feeder

Gibi Pet Tracker: Attaches to any pet collar and connects to your phone

iFetch: Automatic ball thrower

LINK: Wearable uses AI to determine what constitutes intense activity

Tabcat: Lightweight tracking collar, specifically for cats

MarcoPolo: Long range, waterproof, lightweight tracking collar for dogs and cats

Nuzzle: GPS location collar and activity tracker

PetPace: Collar collects pet’s vitals including temperature, activity, pulse, calories consumed (and burned), etc.

Poof: Daily activity tracker (includes sleep!)

Voyce Sensor tracks activity, heart and respiratory rates, quality of rest, etc.

5. Using artificial intelligence (AI) to talk to your pet

The next step in AI might be talking to and understanding your pet! Not long ago, Amazon said it would be selling pet translators within the next 10 years. Already, there is an app available in the U.K. that is a “human-to-cat translator,” but it does not necessarily claim to use AI and reviews are mixed as to its effectiveness.

As already mentioned, robotic dogs can use AI, and sensors provide a means of collecting information for AI to make real-time decisions. PetBot uses AI to recognize your dog, give it treats when you choose (through an app) and take pictures that are sent to your smartphone. Felik is an intelligent pet companion that uses AI to create the same movements a human does when using a laser pointer to play with a cat or dog, keeping your pet entertained while you’re away. Petchatz also allows owners to chat with their dog and release treats to reward their attentiveness.

6. Create your own pet through augmented reality

Augmented reality, sometimes referred to as “mixed reality,” offers its own version of what the future of household pets might be. Rather than robots, what about holograms? This is just one of the many applications of Microsoft’s HoloLens using Actiongram. These holographic pets are able to interact with their owners and fetch balls, perform tricks for treats and even display personalities and emotions like shyness and happiness. These digital companions will build intelligence and learn to interact with people.

British company INDE has created all types of AR systems for many top organizations, including an interactive dinosaur display for National Geographic. Who’s to say what other AR companies may move into the pet industry?

7. Virtual reality allows for much cleaner “pet” homes

VR technology is proving to be an effective training tool, including within veterinary education. Future animal surgeons can learn extensively from this technology in the classroom, but there are other, less serious functions for the technology as well.

Google Cardboard has made it easy for anyone to use VR apps such as Virtual Reality Pet. HTC Vive, the creator of Konrad the Kitten, has really upped its game recently with a new design using Oculus Rift’s handheld touch controller, which allows users to not only see a virtual pet, but to physically touch, pet, hold or cuddle one. FooPets offers both puppies and kittens as adoptable virtual pets that require food, love and attention.

Reading about VR in the pet industry almost begs the question: Will pets experience VR as well? Pawculus Rift was a pretty good April fools’ joke by Cramer, but who’s to say that one day there couldn’t be a use for it? Could VR for your pet keep them entertained while you’re at work? Could it be used to train them? As quickly as technology is moving, new opportunities arise every day, and it may not seem so strange to imagine.

8. Blockchain could verify your pet’s pedigree

Undoubtedly, blockchain technology has the capability to revolutionize transparency in pet pedigrees. Privacy is always a concern within a series of transactions, such as the sale of a pet through multiple owners, but blockchain is designed in such a way that the digital records are not centrally located, nor controlled by one entity. No one can manipulate the data, and it is fully secure. This leaves it virtually impregnable to hackers or information seekers with malintent.

The biggest benefit of blockchain is the ability to share all types of information. From an animal’s breeding history to its yearly veterinary care, health records, dog show awards, training certifications, etc., Blockchain can actually store information from any device, even robots, sensors and microchips.

Internet of things (IoT) becomes the internet of pets

Any of these eight digital technologies can become part of the IoT. It is IoT technology that interconnects them, even in ways we may not yet comprehend. For example, IoT connects the camera in your living room with the smartphone on your desk, allowing you to monitor your pet while you’re at work. It’s also IoT that connects your phone back to the treat feeder, allowing you to reward your pet for behaving while you’re at work! IoT enables the collection and interconnectivity of data. This is extremely important when considering the health and well-being of your pet.

Big data and the microbiome

In recent years, discussion has evolved about the role of the microbiome, or the bacteria in your stomach, and the effects a healthy gut can have on humans. The same is true for animals. Studying an animal’s microbiome and the effect nutrients has on it is not easy. Thankfully, there is another new type of technology called nutrigenomics (the study of how nutrients affect an organism’s genes). It uses a gene chip that allows researchers to test different nutrients, such as vitamins, minerals, yeast fractions, probiotics, prebiotics and even essential oils, to see how adding them to an animal’s diet can improve their digestive efficiency.

Why is this important? By improving the microbiome, or gut, of your pet, you can improve their overall health. It will reduce their chances of getting sick and improve their energy levels. There are very few nutrigenomics centers in the world, and most are dedicated to human research. Alltech has built the only one dedicated to animals and has collected a tremendous amount of data, challenging traditional analytical systems, but big data algorithms have been developed that allow for this information to be analyzed and understood as never before.

The eight technologies, the IoT and the advent of big data described here are digital disruptions affecting nearly every aspect of modern life, including even our four-legged companions. While some of the concepts may seem hard to fathom, given the speed of innovation, concepts that don’t exist today may quickly emerge and become a reality. Advances in the pet industry are already apparent, and new technologies arrive on the market on a daily basis, growing the market ecosystem map. From a commercial standpoint, it’s clear: The pet industry is growing by leaps and bounds, and there are exciting (and profitable!) times ahead for those who cater to people’s love for their companion animal family members.

*The framework for these eight technologies was first proposed in a PwC article.

The corn conundrum

Submitted by aledford on Tue, 08/29/2017 - 10:51

My grandfather used to talk to me about the “spring flush” and the “fall slump.”  To me, these words were as synonymous with the changing seasons as “spring ahead” and “fall back.”

Advancements in management, tillage practices and nutrition have reduced the differences in production that some of our pasturing neighbors might experience with the “spring flush.” However, I still see farms of all shapes, sizes and styles face the dreaded “fall slump” on an annual basis with new crop corn silage. Production losses of 2–8 pounds of milk can be common, coupled with surges in fat and protein and increased instances of hindgut fermentation. Let’s take a closer look at some of the causes and potential solutions to this corn conundrum.

What’s behind the annual “fall slump” with new crop corn silage?

Corn silage can be the most energy-dense forage that we feed. Comparatively, it also has the highest yield potential and is, arguably, the most consistent forage that we harvest. Despite these benefits, there can be some drawbacks, including variability in quality related to changes affecting starch and fiber.

Of all these challenges, there is one in particular that reigns supreme over the king of forages. It is, of course, our friend and nemesis, Mother Nature, which can give us bumper crops or colossal failures. Success often hinges on the weather at the time of planting, silking and harvesting. Temperature and rainfall amounts can swing the pendulum, causing corn silage yield to range from 10 tons to the acre to 30 tons to the acre.  

  

Fiber

There is significant research on fiber digestibility in corn silage. Much of that information shows that neutral detergent fiber (NDF) digestibility does not really increase over time, post-harvest. It seems that, in most cases, we have what we have. 

The greatest influences on NDF digestion are based on genetics, varietal differences and, most importantly, the weather. Years ago, certain cuttings and certain crops just fed well, but we were not sure why because the traditional fiber measurement methods of lignin, acid detergent fiber and NDF did not clearly distinguish performance. New testing methods and research can now demonstrate that the once-leaned-on lignin numbers were good on legumes but wildly variable on grasses, small grains and corn silage. With all the recent research on both 30-hour NDF digestibility and undigested NDF (uNDF240), we know so much more about the fast and slow pools of forage digestion.

A major nemesis to digestibility in our forage crop is the plant itself. We are beginning to understand the effects of cross-linking, the plant’s defense against stress, on our corn silage as well as other forages.  Cross-linking in the fiber portion of the plant will lock up digestibility as a defense mechanism. Because of the unknowns that come with Mother Nature, we can do everything just right and still have a silage crop that feeds below average.

There are three solid fiber-specific strategies for coping with the loss in production in the fall:

1. Feeding digestible corn silage varieties like brown mid-rib can reduce the lag time that it takes for the starch portion of the forage to catch up. Of course, selecting the correct relative maturity for the climate, elevation and soil type will make optimal harvesting much easier to achieve.

2. Tweak the digestible fiber that is delivered to the cow. In the past, wise nutritionists would outsmart the silage slump with a combination of increased starch levels and forage fiber sources like soy hulls, citrus pulp and wet brewers grain. The addition of these fiber byproducts can reduce the percentage of the indigestible forage.

3. Utilization of fiber-digesting enzymes like Fibrozyme® can help unlock some of the forage potential.

 

Starch

The real wild card is the starch portion of the corn silage plant. Research on monitoring the seven-hour starch digestibility levels yields some telling information over time. Starch digestion starts off at a crawl and ends up in a sprint. Many trials show that the starch portion is still increasing digestibility at close to 300 days after harvest. Our milk fat test surely knows the feeding difference between new crop corn silage and feeding out 9-month-old corn silage.

Why does this happen? Kernel type is a vital piece of the puzzle. There’s been a lot of talk of flinty versus floury kernels, and there’s been quite a bit of recent trial work on floury kernel types. 

The protein-starch matrix is crucial to how the corn will digest. The more vitreous the kernel type, the longer it will take to achieve maximum digestibility. Corn breeders are researching varieties and kernel types that will feed out faster than they have in the past. Recent research suggests that lower test weight varieties will feed out quicker than higher test weight varieties.

We can tweak the starch digestion somewhat with management during harvest and some management of the cow. Adequate processing of the kernels at harvest will help to break down the particle size, which will aid in starch digestion. Additionally, starch-digesting enzymes, like Amaize®, have been shown to assist in breaking down some of the starch so that the rumen can utilize it more efficiently. Consult with your seed representative, agronomist and nutritionist to see what the best option is for your soil type, ration and day length.

The benefits of organic trace minerals in cattle

Submitted by aeadmin on Tue, 08/29/2017 - 00:00

Every producer knows that when a beef cow is healthy, her calf has a much better chance of being healthy, too. Trace mineral nutrition is key for maintaining healthy cattle at all life stages. Colostrum quality, calf weight and immune function are among the many benefits from supplementing organic trace minerals in cattle. A study done in 2017 at the University of Florida and published in The Professional Animal Scientist evaluated the response of 160 Angus (AN) and Brangus (BN) cows and their calves to inorganic (ING) or organic (ORG) trace mineral sources.

About the study

The purpose of the study was to evaluate the difference in performance and benefits provided by feeding organic trace minerals versus inorganic trace minerals to cattle on pasture. Beef cows supplemented with organic trace minerals received cobalt, copper, manganese and zinc in the form of Bioplex® and selenium in the form of Sel-Plex®. Beef cows supplemented with inorganic trace mineral products received them as sulfates and sodium selenite, respectively.

The level of mineral supplementation also varied between treatment groups:

  • In the pelleted feed, the organic trace mineral treatment included 25% less copper, 13% less manganese and 29% less zinc compared to the inorganic trace mineral treatment.
  • In the free-choice mineral, the organic trace mineral treatment included 45% less copper, 32% less manganese and 46% less zinc than the inorganic trace mineral treatment.

The best mineral strategy for cattle is one that fits within the producer’s operation, based on their animal requirements and budget and the benefits provided from that mineral product. Organic trace minerals, such as Bioplex and Sel-Plex, are more bioavailable and, as a result, can be added at much lower inclusion rates than the traditional inorganic sources, which not only benefits the environment but, ultimately, the health, well-being, reproductive performance and growth of the animals as well.

Effects of trace mineral source on colostrum

The University of Florida trial revealed that colostrum from lactating cows supplemented with organic trace mineral supplement sources contained 29% more immunoglobulin M (IgM mg/dL) antibodies compared to cows supplemented with inorganic trace minerals (P= 0.07). Cows supplemented with the organic trace mineral sources Bioplex and Sel-Plex also demonstrated significantly higher levels of selenium measured in colostrum —and Angus cows specifically had twice as much selenium compared to their inorganic counterparts (P ≤ 0.001).

"Prenatal immunoglobulin colostrum concentrations in cows at parturition"

The study results also showed that the somatic cell counts (SCC) of the colostrum from Angus cows fed organic trace minerals were 67% lower than the SCC of the colostrum from cows fed inorganic trace minerals. Additionally, Brangus cows fed organic trace minerals had 14.6% lower SCC compared to cows fed inorganic trace minerals.

"Colostrum quality of cows at parturition"

Effects of maternal mineral nutrition on calf weight and antibody levels

As the study progressed, the researchers at the University of Florida observed that calves from cows fed the organic trace mineral sources (Bioplex and Sel-Plex) showed a statistically significant increase in their average daily gains, weaning weights and 205-day adjusted body weights compared to calves fed inorganic trace mineral sources (P ≤ 0.01).

Calves from cows who were supplemented with Bioplex- and Sel-Plex- had 205-day adjusted body weights that were, on average, 22 pounds heavier compared to the weights of calves from cows that were provided with inorganic sources (P ≤ 0.01). Specifically, Angus calves supplemented with Bioplex and Sel-Plex minerals were 33 pounds heavier (205-day adjusted weaning weights) compared to calves from Angus cows supplemented with inorganic trace mineral sources.

"Calf adjusted body weight organic trace minerals"

The researchers also measured immunoglobulin levels and found that the immunoglobulin A (IgA mg/dL) antibody measurements for calves from cows supplemented with organic trace minerals Bioplex and Sel-Plex demonstrated a statistically significant (40.5%) increase in calf serum 24 hours after colostrum consumption compared to calves from cows provided with inorganic trace mineral sources (P = 0.04).

"Calf antibody concentrations after colostrum consumption with organic trace minerals"

Bioplex® offers a range of trace minerals that provide mineral nutrition in a form as close to nature as possible. Bioplex minerals are trace minerals that are bound to amino acids and a range of peptides. They are easily absorbed and readily metabolized, optimizing animal performance. Bioplex trace minerals (including zinc, manganese, copper, iron and cobalt*) are co-factors in the enzymes that are critical for the animal’s defense system, growth and reproduction. Learn more about Bioplex here.

Sel-Plex® is Alltech’s proprietary organic form of selenium yeast. It is an excellent dietary source of selenium and is manufactured to mimic the selenium found in nature. The selenium in Sel-Plex is safer and better able to meet the higher requirements of livestock raised for rapid growth, reproductive performance and health. Learn more about Sel-Plex here.

Michael Woolsey: China as the ultimate disruptor

Submitted by aeadmin on Fri, 08/25/2017 - 00:00

Tom: We’re talking with Michael Woolsey, senior strategic manager for Alltech China. He oversees regulatory affairs and strategic initiatives in Alltech’s largest overseas market. Mr. Woolsey also manages market development activities in Mongolia and Myanmar. We thank you for joining us.

Michael: Good to be here.

Tom: You described China as the ultimate disruptor. Can you elaborate?

Michael: China is the largest overseas market for Alltech, and the pig industry is our biggest customer. Our nutrition solutions for pig farmers account for more than half our sales in China. So, we obviously follow this industry very closely. It’s a massive industry. The revenues of the China pig industry were $160 billion last year. If the China pig industry was a company, it would be number seven on the Fortune 500 — larger than Ford, larger than GM, larger than AT&T.

If you look at the grain that goes into pig farming in China, the amount of farmland is equivalent to the state of California. So, if you take every acre in California to provide grain for China’s pig industry, it still wouldn’t be enough.

There are some really exciting developments going on right now in the China pig industry. Mainly, there’s a massive shift going on. It started about 15 years ago from backyard and small-scale farmers. These farms are being replaced by modern large-scale operations, and this is creating opportunities for a range of businesses that sell to modern pig farms. Everything from equipment, farm building, manufacturers, to genetics, animal nutrition (where we are), to veterinary drugs. Small backyard operations don’t purchase these things and large modern operations do. So, it’s a pretty exciting development right now.

Tom: Smithfield Foods was acquired by a Chinese firm, WH Group. Smithfield accounts for 25 percent of the American pork industry. So, it’s a pretty huge acquisition. What’s the significance for China?

Michael: Yeah. This is a controversial deal both in the U.S. and in China. It was the largest purchase in global animal agriculture history — $7.1 billion, that was the value of the deal.

Four years later, I think there’s evidence that there have been real benefits on both sides. I think for the U.S. pig farmers, they have access to Shuanghui’s impressive distribution network in China. Shuanghui is the biggest meat processor in China. This is access we didn’t have before. And Shuanghui is using their leverage with Chinese retailers to promote American-style pork in a way that’s never happened before in China — hams, bacon, sausages in some exciting and creative ways. And, as a result, we’re seeing record sales of U.S. pork to China right now. Last year’s sales were over $1 billion, up 50 percent from the year before. Nearly all this gain is from Smithfield.

Tom: There’s been some speculation out there that the firm that purchased Smithfield is actually acting on behalf of the government, if not being the government itself. Are you familiar with that speculation? What do you think of it?

Michael: Well, the CEO, Wan Long, he’s actually a member of the National Congress of the Communist Party of China. And he’s the CEO of the largest meat processor and a member of the Party Congress. He’s definitely following guidance from the party.

My first position in China was with the U.S. Embassy back in 2008. Wan Long, the CEO of Shuanghui, invited me to his facility for the weekend. We talked about some of his challenges, and it was interesting. He said he was concerned about the pigs that he was buying in the open market. Shuanghui does not own pig farms, and he was concerned about the inconsistent sizing, the variants, the yields and the carcasses.

He was also really concerned about safety issues, veterinary drug residues and steroids, so he was looking for a safe stream of pork. He asked me, “Would the U.S. government be opposed to my buying a U.S. pig farm?” And I reported the policy that “No, pig farming is not considered a matter of national security and that would be approved.”

I had no idea he was thinking of buying Smithfield at that time. And, four years later, he purchased Smithfield.

But no, there is direction from the party, and all large-scale firms in China are going in this direction. They’re creating global brands.

China has a long history of manufacturing, but they understand that there are more returns in branding and in R&D, that that’s where the real value is. So, the purchase of Smithfield by Shuanghui is an attempt by the largest pork processor in China to capture some added value of a global brand, and there are more purchases on the way.

Tom: China is already the number one animal feed producer, according to the annual Alltech Global Feed Survey, yet much more production is going to be required with the growing middle class. How will they accomplish that?

Michael: Going back to pig farming, there’s a massive shift away from backyard farming to modern scale operations. It’s a development that China has to do. As you mentioned, their farmland is limited, and they’ve got productivity issues. Throughout Chinese agriculture, their yields and productivity are half, or even less, of what you see in the West. The average number of piglets per sow per year is 15. In the West, you see upward of 30 or more.

Their corn yields are half what you see in the U.S. And so, there’s a lot of effort, a lot of policies directed to modernizing Chinese agriculture, bringing in best practices to make sure there’s a reliable supply of safe food for the Chinese. They feel very strongly about self-sufficiency. They feel uncomfortable relying on foreign countries for too much of their food. There are a lot of soybeans coming in, quite a bit of pork. But again, they feel more comfortable if the vast majority of the food that’s consumed in China is produced in China, and they’re taking steps to make sure that happens.

Tom: I think when we think about China, we think about manufacturing, but where in the general scheme of things — the top priorities with the Chinese government — does agriculture figure?

Michael: Agriculture is a critical industry for the party leadership. Again, self-sufficiency is critical. They want to ensure a stable supply of particularly staple products — rice, wheat, corn, and pork is another staple.

When pork prices go up, people notice. It’s the largest meat by far — 63 pounds per person. Number two in China would be chicken at 12 pounds per person per year. And so, ensuring a stable supply of product is really important.

Tom: What is the No. 1 document?

Michael: Every year, the party leadership issues policy documents. The first one they issue every year — the No. 1 document — outlines their work plan for agriculture. It’s indicative of the importance of agriculture to the party, but I have found in my observations of Chinese agriculture policymaking that it’s more of a blueprint. The real work is in other regulatory initiatives, not the No. 1 document. It’s a broad blueprint.

Tom: What importance do environmental and sustainability efforts have in China today? Is there a green revolution of sorts in food?

Michael: It’s a very interesting development the last couple of years. This is an initiative of the administration under Xi Jinping. It started in 2013. They’ve introduced new aggressive measures for water emissions for livestock farming.

They’ve created large zones, particularly in South China, that ban pig farming near sensitive wetlands, the Chinese watershed, also pig farms near residential areas. These are being closed down, and it’s accelerating the trend that I referred to earlier, the smaller farms being closed down, being replaced by bigger farms. The new ones that are opening up are inland. They’re mostly, again, large-scale modern operations, truly massive operations. Some of these are a million pigs and more. So, again, the environmental measures are tough. There are tough standards for minerals, copper and zinc. And a lot of operators are turning to Alltech for our organic minerals to help them cope with these tough emission standards.

Tom: What you just described is the very definition of disruption, I would say.

Michael: That’s right, and Alltech is right in the middle of it, working with our customers to help them meet these requirements.

Tom: There’s been a significant focus by the Chinese government on mineral waste from animal feed. Can you tell us a little bit more about that?

Michael: Again, it’s a part of these new environmental initiatives, where there are some new standards for mineral content and emissions from livestock operations. If an auditor comes out and finds that the mineral levels are above the standard, they don’t issue an environmental permit. They can’t operate. We’re seeing a real spike in our organic mineral sales largely due to these environmental initiatives.

The Chinese — they’re taking additional steps. There’s a draft measure to reduce the amount of minerals allowed in finished feed — copper and zinc. They’re bringing their levels down to what we see in the European Union (EU). For copper, for instance, it’s 25 ppm, which is a significant reduction from where they are today at 150.

Tom: Are Chinese producers facing an increasingly regulated sector, and how are they dealing with that if they are?

Michael: Chinese agriculture has always been heavily regulated, but in China, oftentimes the key is what regulations are implemented. You have lots of regulations, and some are implemented and some are not. The environmental rules are being implemented in a way they weren’t before. It’s a tough environment for Chinese operations.

Tom: And how about representing an American company within that regulatory environment? Does that have its challenges as well?

Michael: For operations in China, we are held to a higher standard on average. When regulations come out, they tend to enforce those on foreign operations before local operations, and it’s a bilateral issue between the U.S. and China. This is in tandem with a new “made in China” initiative. In some sectors, it hasn’t impacted agriculture yet, but in other areas like semiconductors, telecoms, equipment services — they’re introducing policies to make it difficult for multinationals to operate and to make sure that the Chinese companies win out. It’s a warring trend for foreign operations in China.

Tom: This burgeoning middle class, with its burgeoning demand, is that creating opportunities for exports from other countries, including the United States?

Michael: Oh, absolutely. The middle class in China continues to boom. When people are in the middle class, the first thing they do is improve their diet — more meat and other protein, more calories. So, we are seeing in animal agriculture a real spike in the importance of beef, where China is less competitive.

It takes, on average, 8 kilos of grain to raise 1 kilo of beef. Grain prices are higher in China than in other countries.

The U.S. has been blocked from entering China through official channels because of bovine spongiform encephalopathy (BSE), and there’s some movement very recently. We’ll have official access this summer. A lot of beef is coming in from Australia and from the U.S., after they open the market.

Dairy is another big item — a lot of dairy products coming in from New Zealand, Australia, the EU. Infant formula is a $4 billion market for overseas operations. And so, yes, the growing middle class is creating opportunities for countries around the world.

Tom: The Chinese leadership has to think about domestic issues first, but does China have a future larger role in the global food market?

Michael: China is an export powerhouse in a number of sectors, but agriculture is not one of them. It’s not really a focus right now because they’re mostly concerned about ensuring, again, a sufficient supply of food for Chinese people. They’ve actually had export restraints on their ag products in the past. It’s not really a focus to export, but there are some exceptions. They want to make sure they have enough for Chinese consumers.

Tom: China first.

Michael: China first.

Tom: You also focus on the emerging markets of East Asia — Mongolia, Myanmar. What can we expect to see happening in those countries?

Michael: These are the two newest markets for Alltech, and they’re very different. Mongolia, it’s a small market. There are only 3 million consumers. The middle class has only less than a million, but there’s a small, emerging, modern layer in the pig sector that’s creating some opportunities for us. Long term, I think what’s really exciting potentially for Mongolia is exporting beef to the 1.5 billion consumers in East Asia. Right now, they’re prohibited from exporting because of animal disease concerns. They have foot-and-mouth disease, but Mongolia sees the opportunities, and they’ve created a plan that was accepted by the World Organisation for Animal Health. The plan was accepted. They just need to implement it. It takes resources, but maybe in two to three years, they’ll have their beef approved. It could be a billion-dollar item for them in the first year. They have some natural advantages, a lot of grassland for raising beef animals. So, I think long term, that’s probably the most exciting potential opportunity.

Myanmar is a very different market. Much larger — 50 million consumers. Of course, the political reforms in the last year have been a real catalyst for us. U.S. trade sanctions were lifted last year due to the election of Ms. Aung San Suu Kyi. It’s an exciting time to be in Myanmar right now. They had 40 years of military rule. Suu Kyi won with 98 percent support. Imagine what the U.S. could do with 98 percent support for the president. It’s an exciting time in Myanmar. Real opportunities, short term, I think, in layers and broilers and longer-term opportunities in pigs.

Tom: What in your view, Michael, does it take to make wise, successful investments in these East Asia markets?

Michael: I think, first, you have to listen.

Alltech has always been a company that likes to go in first when we see opportunities. And I tell you, the reception that we’re getting in both places — operations are eager to talk with us. They’ve got challenges. They want to hear about best practices from overseas. And so, listening to their challenges and building relationships for the long term, I think that’s what’s key — not expecting the quick return, but being there for the long term. People appreciate that.

Tom: How does China’s disruption and these emerging Asian markets, how does all that affect the average consumer’s dinner table?

Michael: There’s an exciting development related to the Shuanghui purchase of Smithfield.

Shuanghui, their objective, their goal is to increase the amount of chilled meats that they’re selling. Right now, only 30 percent of Shuanghui’s meat sales are chilled. The 70 percent — it’s the traditional marketing channels of warm carcass that’s cut up and sold in wet markets. The margins are obviously a lot lower. And so, one of their strategies for increasing their chilled meat segment — they’ve partnered with an e-commerce company called JD.com. This company is doing some exciting things. They’re creating a cold chain system, a warehouse and distribution cold chain system from the warehouse to the customer, selling fresh chilled foods, including packaged meats. Smithfield, Shuanghui, they have a strategic cooperation agreement to sell packaged Smithfield meats through jd.com. So, if a customer in the morning decides they want to have hot dogs from Smithfield for dinner that night, they bring out their cellphone, dial up JD.com, order the hot dogs, and the truck shows up later that afternoon. Chilled distribution the entire way to the consumer’s door. So, it’s a superior product. It’s what consumers want. It’s an exciting development.

Tom: It’s pretty amazing. I guess it’s not beyond imagination that someday a drone will show up. What about your work do you enjoy the most?

Michael: Well, in China, every day there’s a new challenge.

My last tour in the foreign service was Beijing. And when that tour was over in 2011, I had a choice to return to Washington or retire from the foreign service and do something else and stay in China. That was an easy decision. And so, I stayed in China. There’s just so much going on in agriculture in China. It’s a challenging market, but, again, a lot of opportunities. And at Alltech, we’re a part of this revolution in animal agriculture in China. And so, it’s very exciting.

Tom: Michael Woolsey, senior strategic manager for Alltech China. We thank you for joining us.

If the China pig industry was a company, it would be number seven on the Fortune 500.

Is Walmart now in the assisted living market?

Submitted by aeadmin on Thu, 08/24/2017 - 00:00

ONE: The Alltech Ideas Conference (ONE17) in Lexington, Kentucky. With this being my fourth year in attendance, one might believe I’ve become a master at preparing for the event. Quite the opposite. Dr. Pearse Lyons, the mastermind behind Alltech, is intricately involved in all events. His mind is a constant place of creativeness, innovation and disruption. I’ve yet to experience an event that did not bypass my expectations. The best method of preparation is to enter with an open mind.

Image removed.

This year’s event challenged my open mind. It provoked my ideals and basic cognitive thinking. The concept of keeping agriculture real has been at the forefront of my life. In theory, the ideas presented at ONE17 were sound. I couldn’t help but wonder if some were feasible, practical and, well, real.

One such discussion centered around the grocery stores of tomorrow, or lack thereof. It is estimated that grocery stores as we know them today will soon become “daycare for the elderly.” One statistic went as far as to say box stores will be eliminated by 2028. Despite supporting research conducted by the United States Department of Labor through Willard Bishop, LLC., to say there was skepticism on my mind is an understatement. The research showed fewer Americans are buying food at grocery stores, especially younger consumers, leading to grocers becoming obsolete.

In theory, there may be truth in these statements; however, I wasn’t buying it.

Practically versus concept:

  1. Observation: I know a handful of decision-makers who have begun ordering groceries online. Regardless, the bulk of our family and friends continue to be drawn to the likes of Walmart or Target.
  2. Personal application: Living in a rural area, fresh produce isn’t available for shipping. Online shopping won’t be saving me fuel dollars until this service is offered. When I compare prices of Aldi to Amazon, my best buy is Aldi’s.
  3. Technical hindrances: There are both delivery and pickup methods offered by Walmart. In concept, my expectation was a great service. Eventually, they may hit the target. However, from my experience, numerous bugs need to be worked out. After spending hours trying to input my list, I ended up driving 30 minutes to purchase my items in person.
  4. Lack of convenience: Shipping and picking up groceries each come with a major shortcoming — today’s society needs an experience that is fast, convenient and easy. Anyone can enter a physical store without a list and walk out with $300 in items. Online ordering requires the time and patience to enter grocery items in an app or other device.

As these thoughts bounced through my mind, the presenter unexpectedly met my skepticism with additional points. I wasn’t yet committed to making a sale; however, I was listening.

Outside of online ordering, I was surprised to learn of the additional types of applications that are currently being applied and tested with real consumers:

  1. Amazon Go (unmanned store): Jackpot. No more worrying about ending up in the “talkers” check-out or being stuck in the line that never ends. In contrast, I couldn’t help but wonder if risk management challenges existed. What are the shoplifting rates?
  2. Egg vending machines: This portion of the presentation ended with the mention of Asian vending machines for eggs, fruits and perishables, a real-time service that has become as common as phone booths once were. While traveling, I have noted an increase in the variety of vending machines. During a San Francisco Uber ride, my husband and I struck up a conversation with the driver. Our moonlighting Uber driver held a daytime gig designing vending machines for perishable foods. The current project was a concept-phase fresh fruit, smoothie machine.

The older my mind becomes, the greater my stubbornness grows. I left ONE17 with the conclusion that while these concepts of the future sound dreamy, they won’t be practical nor will they replace big box stores.

Ding-dong. Two weeks following ONE17, I realized my conclusion, potentially, had some issues. In early June, Amazon announced its intention to purchase Whole Foods for $13.7 billion...in cash. I was quickly transported to last year during the holiday season. The historic holiday season set precedent, moving more sales transactions online than in the stores. The powerful retailer has the secret to closing big box stores, and it’s called Amazon Prime. It’s estimated that in the U.S., 60 million people are Prime members, and who tends to spend more on Amazon? Those Primers.

The “cha-ching” sound was echoing through my now open mind as I gave in to my stubbornness and acknowledged: big box stores may really become “assisted living” for our elderly, a place for social activity rather than a commerce center.

Farm Innovation Series: White Rock Farms of Peachland, North Carolina

Submitted by aeadmin on Tue, 08/22/2017 - 00:00

Calf care is key to the profitability and longevity of a herd. When it comes to attention to detail and calf health management, there are few better than White Rock Farms in Peachland, North Carolina.

Image removed.

Owned and operated by Roddy Purser, White Rock Farms of Peachland, North Carolina, includes a 600-head Jersey dairy farm, hog houses and a layer operation. An innovative first-generation dairyman, Roddy saw opportunity in the dairy industry, and he knew that the secret to success was putting together a capable team equipped with both passion for the industry and the knowledge to build a successful herd.

Dakota Sparks is one of those team members. She is in charge when it comes to managing calves at White Rock Farms.

Image removed.

Drew Gibson and Dakota Sparks, herd managers at White Rock Farms

Dakota has helped White Rock Farms to maintain a less than 1 percent death loss on the farm since the beginning in 2014. She attributes this astounding success to four key elements: an employee dedicated to calves, cleanliness, a prevention approach and no cutting corners.

How White Rock Farms has kept their calf death loss to less than 1% since 2014

1. An employee dedicated to calves

Dedicating an employee to calves can be difficult for many farms, but as a farm grows, it becomes even more important.

Dakota is the manager of White Rock Farms’ calf area, a responsibility she takes very seriously. Feeding

calves twice a day starts with the White Rock Farms’ team removing water buckets and replacing them with milk buckets. This gives employees the opportunity to check calves while emptying, cleaning and refreshing water. These opportunities to observe calves are important for identifying any illnesses or abnormalities, so Dakota and her team devote their full attention to the task.

2. Cleanliness

Once utilized, every hutch is cleaned. All sand and gravel are removed, and the hutch is kept vacant for one to two weeks.

Once ready for a new resident, Dakota’s team utilizes a layer of black cloth at the bottom to keep the sand from falling through and then adds new gravel. This attention to detail reduces disease transmission from one calf to another, giving newborn calves the best possible opportunity for a healthy start. Not only are the hutches cleaned and sanitized after each calf, but calf buckets are sanitized after each feeding.

After the calves are fed milk, their buckets are cleaned in a three-stage process:

Image removed.

  1. The first water bath includes 125°F water with soap.
  2. The second bath contains 145°F water with soap.
  3. The third and final bath holds cold, chlorinated water.

Buckets are then stacked to air dry before the next feeding.

3. Prevention approach

Antibiotics are used only in instances of severe illness, but are rarely needed, according to Dakota. By taking a preventative approach, the need for therapeutic treatment is minimized.

White Rock Farms pasteurizes all colostrum and milk that is fed to calves and frequently utilizes electrolytes in water to help give calves a little boost. Dakota remarks that, when used properly, there can be substantial cost savings to pasteurizing milk for calves, especially once the cost of the pasteurizer is recouped (which occurred in two years for White Rock Farms).

4. No cutting corners

All colostrum is tested. This test is to identify the quality of the colostrum based on IgG antibody levels in the milk. If it meets the requirements, it is then used, refrigerated or frozen if not utilized within 24 hours. The frozen containers are organized and marked with the necessary information to enable easy retrieval of bags.

Roddy is confident the extra investments are worthwhile, as evidenced by heifers that are outperforming their mothers. With a solid foundation of nutrition, their calves have a healthy jumpstart on reaching breeding age with minimal illness.

White Rock Farms is a customer of CPC Commodities, based in Cowpens, South Carolina and is currently feeding the following Alltech products: Select GH®, Yea-Sacc®, Integral® A+, Bioplex® Hi-Four, Optigen® and Sel-Plex®

How can your sows get more from fewer minerals?

Submitted by aeadmin on Thu, 08/17/2017 - 00:00

Traditionally, mineral supplementation has been achieved through the use of inorganic minerals. However, developing technologies have ushered in a new era in mineral nutrition.

The newest edition of the “Brazilian Tables for Poultry and Swine” verifies the efficiency of organic mineral supplementation in monogastric animals, with farmers starting to implement organic mineral nutrition and seeing improvements in efficiency and gains in performance. Today, we know that feeding the right form of mineral is key to optimizing herd performance, health and productivity.

Studies show that organic trace minerals (OTM):

  • Offer higher bioavailability than inorganic minerals (Close 2006).
  • Have high biological activity (Peters and Mahan 2004, 2014).
  • Reduce concerns about negative mineral interactions (Peters et al. 2014)

Piglet quality starts with the sow

Switching mineral forms can have a significant impact on your sow productivity and your overall pig production. Sows transfer a significant amount of minerals to the fetus during pregnancy (Mahan et al. 2009), meaning that the gestation and lactation periods are crucial times in the sow’s productivity and in her piglets’ viability.

A study published in the Brazilian Journal of Animal Science found that sows given the organic form of trace minerals produced piglets with increased weight at birth and, after 21 days, higher iron content in the liver and blood.

“By supplying Bioplex® trace minerals, we are providing the sow with minerals that are better absorbed, which in turn makes the sow more productive, and more minerals are passed on to her offspring,” says Russell Gilliam, Alltech’s U.S. swine business manager. “The end result is that we are able to lower income cost in producing a weaned pig.”

A “more with less” approach

Alltech’s innovative Total Replacement Technology™ was developed in response to modern production and the mineral requirements that are now demanded by your herd. Alltech has proven that modern management of mineral nutrition can be carried out by the inclusion of organic trace minerals in the form of Bioplex® and Sel-Plex® at significantly lower levels than inorganic trace minerals while still improving performance.

Now more than ever, efficiency is a primary focus in the pig industry. Improper mineral supply can have major consequences for health and productivity and, as a result, come at a high cost.

I want to learn more about nutrition for my pig herd.

Blurred lines: Traditional and organic farming

Submitted by aeadmin on Wed, 08/16/2017 - 00:00

When choosing between organic and conventionally grown produce, we tend to see it as an “all or nothing” decision. However, many growers are using techniques that have traditionally been seen in organic farming and are incorporating them into conventional farming.

The gap between organic and conventional growers is narrowing with every passing year as new technology is making it easier to incorporate more natural methods into traditional management practices.

Soil management

Many growers are turning away from using traditional tillage practices in an effort to nurture the agribiome in the soil. Instead of churning the soil annually, many will now till only when needed to combat soil compaction.

Soil testing

Soil testing is done to guide precision nutrient application. The grower can apply only the nutrients that are shown as deficient on the tests and only in the correct areas, thus increasing the efficacy of the nutrients while decreasing some of the costs associated with soil treatments.

Cover crops

Many conventional growers are also using various cover crops and polyculture, the practice of growing multiple crops in the same area. These practices aid in maintaining nutrient-rich soils through organic matter breakdown, and they also help prevent weeds.

Crop scouting

Early detection of pests, diseases and nutrient deficiencies through crop scouting can reduce the use of pesticides and other inputs and allow for more precise applications of treatments to address crop issues.

A natural approach

Naturally based crop inputs, such as those that use amino acid technology, are being used by growers throughout the plant growth cycle. These inputs result in improved soil biology, plant health and greater yields, all while decreasing the use of synthetic inputs.

More growers are coming to the realization that there is no need to compromise growth, yield or profit in the pursuit of improved sustainability.

For more information, or to discuss ways in which you too can incorporate some of these techniques into your operation, contact your local Alltech Crop Science representative.

Game of drones

Winter has come to the world as it is known to the hardworking honey bee. “Game of Thrones,” the popular HBO series based on George R. R. Martin’s bestselling books, set in a harsh world, its characters struggling as they face hard truths, might be a fitting metaphor for what is happening in the kingdom of the honey bee. But this is no game.

The European honey bee, Apis mellifera, is the most economically valuable pollinator of agricultural crops worldwide. Bee pollination is responsible for more than $15 billion in added crop value in the United States. Especially dependent on bees are specialty crops such as almonds and other nuts, berries, fruits and vegetables. And there is the product of the bees themselves: honey.

“Sadly, when all of this started to happen back around 2005–2006 with the bees just disappearing from their hives, nobody knew what to call it, so the media latched onto something called CCD, or colony collapse disorder, and that’s just a misnomer,” said Michele Colopy, program director at the Pollinator Stewardship Council in Akron, Ohio. “It is not explaining the issue well enough, and we would like the media to stop using it.”

In fairness to the media, the term originated in the mid-2000s with the U.S. Department of Agriculture (USDA), where scientists were scrambling for an explanation. But the origins of the term hardly matters.

Beekeepers had awakened to a nightmare of sickened, even vacant, hives.

Think of their anxiety this way, suggested Colopy: “Honey bees are a beekeeper’s livestock, and they suffer under the same health stresses as any four-legged livestock that doesn’t have wings.”

What happened? As Colopy stressed, in recent years, it has become clear that no single factor is responsible. According to the USDA, research is beginning to strongly suggest that CCD “may be a syndrome caused by many different factors, working in combination or synergistically.”

As in the mythical “Game of Thrones,” the very real forces arrayed against the kingdom of the honey bee, the hive, have converged to lay siege in many guises and from many directions.

Some likely candidates have recently been identified. There remains speculation about additional culprits.

What we know about “colony collapse disorder”

According to the USDA, researchers have documented elevated pathogen levels, and a wide array of pesticides have been present in the wax and pollen in both CCD-affected and non-affected apiaries, with none linked definitively to CCD.

Pesticides

“The wax (inside the hive) holds onto pesticides,” said Colopy. “It is a sponge. So, when a pesticide is brought into the hive on pollen or nectar or on the bodies of the bees, the toxin in the pesticide stays active for a longer time because it’s in the dark — most pesticides break down in sunlight.

“But it’s not that we can suddenly open the hive to sunlight to change this, because the wax still holds onto the toxin and protects it,” she continued. “The toxin leaches through the wax.”

Beginning in 2015, beekeepers began to report more bee deaths in late summer than in winter. It was a troubling sign. Hives are expected to be stronger and healthier in warm weather and more stressed in the cold months.

“What is happening at the end of summer is the full effect of the pesticides,” explained Colopy. “They build up across the summer, and the bees are eating these toxins. This slowly kills off the adult foragers. Then the whole organism of the hive is thrown off because different bees have different duties, based on their age.

“If you suddenly have too many foragers dying and everybody gets shoved ahead in their duties, you start to throw off the life cycle of the hive,” she continued. “The queen’s reproduction ability declines; there aren’t enough bees to help raise the brood, so you begin to slowly lose the population, and this is where that so-called ‘colony collapse’ comes in.”

Mites

In addition to pesticides, infestations of mites have taken a toll.

Varroa destructor, a parasitic mite, propagates within the brood cells of bees. The mites can do serious damage to their hosts' health, latching on and feeding on hemolymph, insects' rough equivalent to blood. Bees are left with open wounds, making them susceptible to infection.

Adding insult to injury, noted Kentucky State apiarist Tammy Potter, is a finding that Varroa mites can introduce viruses — one, in particular — to honey bee colonies.

“Lake Sinai virus, named for a lake in South Dakota, is fairly new,” she said. “It has characteristics that look remarkably similar to what we used to call colony collapse disorder.

“Forty-six percent of our (Kentucky) apiaries have high Varroa mite counts,” continued Potter, referencing the most recent USDA Honey Bee Health Survey. “There was only one from this particular year that did not have a virus present. The other 23 did.”

Researchers and the USDA have urged a change in management strategy, including more frequent sampling.

“Given the biology of the Varroa mite, the best management practice is to sample your bees for mites four times a year,” said Potter.

In 2015, the EPA approved the use of oxalic acid (OA) as a Varroa mite treatment. Various studies have shown OA to be effective in a variety of climatic conditions with an efficacy as high as 97 percent in a broodless period.

But it’s far too soon to breathe easy. Researchers at Purdue University have discovered that a sister species of the Varroa destructor mite is “shifting from feeding and reproducing on Asian honey bees, their preferred host, to European honey bees, the primary species used for crop pollination and honey production worldwide.”

While Varroa Jacobsoni mites have not been found outside of Papua New Guinea, Purdue researcher Gladys Andino said vigilance is needed to protect European honey bees worldwide from further risk.

"This could represent a real threat,” said Andino. “If this mite gets out of control and spreads, we might have another situation like V. destructor."

The Purdue researchers note with caution that “V. destructor made the same host leap at least 60 years ago, spreading rapidly to become the most important global health threat to European honey bees.”

The Honey Bee Health Coalition, an organization of beekeepers, researchers, government agencies, agribusinesses, growers, conservation groups, manufacturers and consumer brands, is holding its first Mite-A-Thon in September. The event is “a national effort to collect mite infestation data and to visualize Varroa infestations in honey bee colonies across North America within a one-week window.” The Varroa monitoring data will be uploaded to www.mitecheck.com.

Continuing research also focuses on additional possible CCD factors, such as the synergistic effects of the Nosema fungus and pesticides, and of pesticides and other pathogens.

Monocultures

Even before CCD came along, one of the biggest challenges for native wild bees has been the agricultural specialization that has produced huge fields of just one crop: the monoculture.

The almond groves of California, for example, are a sea of blossoms in February.

"But for the rest of the year, there's nothing blooming," Claire Kremen, a conservation biologist at the University of California, Berkeley told NPR. "In fact, in places where we have very large monocultures of almond, we don't find any native bees anymore."

So honey bees must be trucked in from all over the country. And the industry's migratory characteristic may also contribute to the colony collapse problem.

“If you start in South Dakota and you take your bees to California, where there are also honey bees from Indiana, Kentucky and Texas, that virus can be spread,” said Potter.

Time is money, and this travel leaves little time to sample for mites, which can be a lengthy process. However, necessity has inspired invention, said Potter.

“There is a new tool on the market to help beekeepers quickly sample their bees,” she said. “I think you will begin to see a significant decrease in hive mortality.”

The Varro Easy Check tool uses an alcohol solution to remove mites from up to 300 bees at a time.

Forage land development

Working in combination with the impact of monocultures is the development of countryside and forests. Much pollinator habitat has been lost to urban and suburban development as well as surface mining.

“Many pollinators are adversely affected when large, intact tracts of habitat are broken up into smaller, isolated patches by road construction, development or agriculture,” observed a joint study by the Center for Biodiversity and Conservation at the American Museum of Natural History and the Greenbelt Native Plant Center. “These habitat fragments may not be large enough to meet all pollinator needs by themselves.”

Honey bees are left without the diverse sources of nectar and pollen they need to thrive when confronted with multiple factors known to affect their survival, growth and reproduction, the study concluded.

How can we help the bees?

What can be done to improve survival prospects for these industrious, socially sophisticated creatures and the human agriculture that depends on them?

A survey of its beekeeper members by the Honey Bee Health Coalition found a demand for companies to offer supplemental pollen patties that address “specific regional, seasonal, and/or life cycle challenges and objectives.”

They identified two primary drivers for beekeepers to feed protein supplements: “to stimulate colonies to produce more brood at certain times of year; and to offer nourishment when natural pollen flow is lacking.”

Initial trials of the Alltech supplement Bee Pollen-Ate® suggest a promising response.

“We’re increasing brood during low pollen levels,” said Kyle McKinney, Alltech’s crop science manager in Costa Rica. “It means the whole hive is active and healthy. When the queen lays the brood, the worker bees come in and start feeding the brood and building up the comb to protect the brood. We know with certainty that what we’ve seen in Costa Rica, during low pollen season, supplementing with Bee Pollen-Ate, we have a healthier and more active hive.”

Acting as something of a worksite food truck, the quarter-inch-thick patty is placed atop the comb where the bees are working.

“They come up and they feed on the patty and go back to work,” explained McKinney.

There are numerous feed supplements on the market, and many beekeepers make their own “patty” of supplements.

“I see about a 50-50 split between people who want to make their own patty using their own recipe versus people who want to buy a finished patty,” noted McKinney. “But even those who make their own are using our Bee Pollen-Ate as the protein supplement.”

McKinney’s research partner, Tyler Bramble, general manager of Alltech ruminant nutrition in Visalia, California, said it appears that many commercial companies making pollen substitute products are in a race to see who can pack the most protein into a bee supplement patty.

“I’m not convinced that more is always better,” he said. “I think you really need to look at the form and the digestibility. We see in livestock animals deleterious effects as protein levels become ridiculous. It costs the animal energy to process and get rid of all that extra protein.”

The distinction between the Alltech product and others, Bramble noted, is the particular expertise behind its development.

“With Alltech’s core competencies being animal nutrition and yeast fermentation, we understand all the different parts of a yeast cell,” he said. “That’s our business. We fractionate the yeast cell, and, because of our knowledge of the yeast cell and its various components, we are able to pull out protein, carbohydrate and nucleotide-rich portions of the cell. That enables us to make a designer pollen substitute.”

With McKinney in Costa Rica, where it is now winter, and Bramble in California, where summer is in full force, the two are teaming up to carry out continuous trials of Bee Pollen-Ate. Their findings are anticipated by spring of 2018.

A “what if” to ponder

But what if all of our best efforts fail to restore the honey bee population to levels required for crop pollination? One possibility makes the long, deadly winter of “Game of Thrones” seem springlike by comparison.

There is the prospect that in the not-too-distant future, farmers might not have to rely on declining bee populations. For example, researchers at Tokushima University in Japan have used the CRISPR gene-editing technique to produce seedless tomatoes, which do not require pollination at all.
