Bovine respiratory disease (BRD) is the number-one cause of feedlot cattle death in North America and represents more than 70% of all feedlot death and sickness. BRD is the single-largest source of morbidity and mortality in feedlots, causing an estimated $2–3 billion in losses annually (Fulton 2009; Irsik 2006). So how do you treat BRD?

First, you need to know that the phrase “treating BRD profitably” is nearly an oxymoron. Once an animal gets BRD — or shipping fever, as it’s sometimes called — four separate economic factors are negatively impacted: treatment costs increase, productivity decreases, labor costs increase and the likelihood of a BRD re-treat, chronic re-treats and/or death increases as well. Especially in a tight beef cattle market, relying on being able to treat BRD while staying profitable is practically impossible.

What is BRD and how do you spot it?

BRD is the general term for any disease of the upper respiratory tracts (e.g., bronchitis, rhinitis, tracheitis) or lower respiratory tracts (e.g., pneumonia). It is known as a “disease complex,” stemming from three factors usually working in combination: stress, a viral infection and a bacterial infection. BRD normally impacts cattle in the first four weeks after weaning, and it can be fatal.

Symptoms of BRD:

• Droopy ears
• Fever
• Lethargic behavior 
• Lack of appetite (going “off-feed”)
• Rapid, shallow breathing
• Coughing
• Bloody or excessive nasal discharge

Four strategies for beating BRD in your feed yard

A common cliché in sports is that “the best defense is a good offense.” The same principle applies to BRD. The best way for you to defend against having to treat for BRD is to have a proactive, offensive-line strategy that prevents BRD in your receiving program. Here are four things you should do to prevent BRD:

1. Reduce stress at all costs

Investing a bit more to ensure the receiving health of your cattle will pay big dividends when it comes to BRD. Remember: cattle have just endured a long, strenuous trip to your yard, so doing everything you can to reduce their stress upon arrival is critical. This begins with providing a good, clean environment with as little overcrowding and dust as possible. Pay special attention if and when adverse weather occurs (e.g., excess heat, cold, rain, etc.) and adjust accordingly to accommodate them. Be sure to provide sufficient bedding as well so the animals can get some much-needed rest. The initial process of co-mingling can introduce countless diseases, even beyond BRD, so giving cattle to have a clean place to rest will allow them to both settle down and fight off any health challenges.

Additionally, having your team trained in low-stress handling practices will help keep cattle calm when they arrive. This means limiting the amount of yelling, excessive noise and the use of electric prods to keep stress to a minimum.

2. Provide good nutrition early and often

There are three keys to preventing BRD via nutrition. Though often overlooked, the first and most important key when cattle are arriving to the feedyard is getting them to drink water. Water is a critical first nutrient. After a long, stressful trip, getting cattle clean water as quickly as possible will help them acclimate and address any dehydration they could have experienced during transportation. The second key to preventing BRD is providing highly palatable, nutrient-dense feed. Especially during the first four to five days, getting cattle to eat much of anything may be a challenge. A good choice to include in your ration would be either a wet or dry distillers grain (depending on what is available in your region). Distillers grains are high in protein, very palatable and are generally cost-effective for a start-up ration.

Sometimes, the smallest ingredients can have the biggest impact on your cattle’s health. Providing the right micronutrients to maximize health and performance is the third and final nutritional key to preventing BRD. Establishing good gut health and mineral status proactively are paramount when attempting to stop BRD before it starts. Feed additive products from Alltech, such as Bio-Mos, can help drive gut health, and Alltech’s Bioplex and Sel-Plex support maximum trace mineral status. Both of these products are backed by peer-reviewed scientific research and have been used by producers as a part of their comprehensive BRD programs.

3. Establish a vaccination program with a vet you trust

Step one in this process may be developing a relationship built on trust with your vet. This goes beyond just “knowing” your vet to actually having full confidence that the vaccinations you are providing will set your animals up for success. A skilled local veterinarian is your best ally to make sure that the vaccines are working most effectively to fight BRD outbreaks. Furthermore, vaccination histories should play an important role in where you source your cattle. For example, finding animals who have been vaccinated as many as 45 days pre-weaning and again before shipping will help boost your ability to prevent BRD in the feed yard.

4. Use your tools wisely: Good pen riders and technology

Remember, cattle are animals of prey — meaning that they will do everything they can not to appear sick or wounded. A skilled pen rider with a keen eye is still your best preventative tool against BRD. Not every case of BRD can be prevented, but putting an end to it before it becomes critical can make all the difference. There can be as much as a three-to-five-day gap between when an animal begins to experience the symptoms of BRD and when those symptoms can be visibly detected. This makes early identification all the more important for a pen rider. The longer BRD goes undetected, the more “catching up” an animal will need to do once treated. That means lost money for your yard. As such, checking animals multiple times a day is good, profitable prevention against BRD.

New technologies continue to aid in the preventative fight against BRD. Many of these technologies still need further development before being profitably introduced, but progress is being made. Early detection swabs, drones, smart ear tags, facial recognition cameras, sensor-based hydronic shoots and much more will help reduce the labor needed to effectively manage cattle and improve overall animal welfare.

Again, your best defense against BRD is a good offense. By putting these preventative strategies in place, you are giving your cattle the best chance to be healthy and profitable. Your ability to combat the number-one feedlot disease can and will make a big difference for your operation today.

According to the Centers for Disease Control and Prevention (CDC), Salmonella is the cause of an estimated 1 million food-borne illnesses in the United States every year, including 19,000 hospitalizations and more than 300 deaths. The most common symptoms of a Salmonella infection are diarrhea, fever and abdominal cramps. Serious Salmonella infections are more likely to manifest in those who are under 5 years old or are over 65 years old, or in those with weakened immune systems (e.g., diabetics or cancer patients). Although illness from Salmonella is often the result of improper food preparation or several other factors, poultry producers and backyard flock owners can help reduce consumer risk through good management practices.

Potential sources of bacterial contamination include: 

• Wild birds/pests (e.g., beetles, flies or rodents) 
• Water 
• Visitors 
• Hygiene 

In poultry production, there are eight key areas that must be given attention in order to reduce bad bacterial contamination on-farm and aid in the prevention of Salmonella.

1. Clean facilities and dedication to biosecurity:  Residual contamination from previous flocks is a common cause of Salmonella in birds. Cleaning areas that birds often touch (e.g., drinking and feed containers) or frequent (e.g., the coop) before the birds arrive and after they leave can help reduce the prevalence of Salmonella. Effective biosecurity and pest control are also key to avoiding contamination in the coop. 

2. Feed:  Contaminated grains and feed ingredients can increase the risk of Salmonella in the final feed. Use heat-pelleted feed, and source feed from mills that maintain stringent quality standards. 

3. Water management:  Water management is a crucial part of any Salmonella control program for poultry, since water can serve as a medium for the organism to spread from bird to bird. Chlorination, as well as the use of organic acids in drinking water, can help to reduce Salmonella levels in the flock. 

4. Dust:  Like water, dust can also foster the spread of Salmonella. Try to keep dust levels in and around the coop below 3 milligrams per cubic meter. 

5. Litter and manure management:  Poultry litter and manure with high moisture and pH levels allow Salmonella to thrive. Managing the moisture and pH of the litter and manure can be effective ways to prevent it from spreading. 

6. Managing gut flora: Establishing and maintaining proper gut flora soon after hatching is critical for mitigating Salmonella contamination. Programs that include the use of probiotics, organic acids, enzymes and yeast technologies have proven effective at maintaining optimal gut health. Several Alltech products that can support gut health — including Sel-Plex^®, Bioplex^®, Allzyme^® ;SSF, Bio-Mos^®, Yea-Sacc^® and Integral^® A+ — are incorporated into all Hubbard Premium Quality poultry feeds.

7. Coccidiosis: Intestinal challenges caused by poor gastrointestinal integrity can have a major impact on Salmonella levels in broilers. As such, strong coccidiosis management should be part of every Salmonella control program. 

8. Vaccination: Especially at the breeder level, the use of vaccines has the potential to reduce the prevalence of Salmonella among day-old chicks. You should only purchase chicks from a reputable source. While vaccines can be applied to backyard poultry, a poultry veterinarian should be consulted to design a suitable program for your birds. 

Cleaning and personal hygiene for your safety 

People can get sick from eating Salmonella-infected meat or eggs or by touching infected poultry or housing. Birds can carry Salmonella but show no symptoms or signs of illness. Fortunately, however, there are several factors that can boost protection: 

• Always wash your hands with soap and water (or use hand sanitizer) immediately after touching birds, their housing, eggs or meat. Require visitors to do the same. 
• Do not allow backyard poultry inside your home, especially where food or drink is prepared, served or stored. 
• Wear a specific pair of shoes when taking care of or visiting birds that you do not wear elsewhere. Leave this footwear outside and request that visitors to do the same. Rubber boots are a popular option. 
• Do not eat or drink where poultry live or roam. 
• Do not kiss or snuggle backyard poultry and then touch your face or mouth. 
• When cleaning the equipment or materials you use to raise or care for your birds, do so outdoors, not inside.
• Any individuals with potentially weakened immune systems should not touch the birds.
• Source young birds from government-inspected hatcheries or reputable sources that have a bird health plan.
• Maintain a clean coop and collect eggs often. 
• Clean dirty eggs with fine sandpaper, a brush or cloth — but DO NOT wash eggs with cold water, as this can pull Salmonella into the egg.
• Refrigerate eggs after collecting them and cook them thoroughly before serving.

To expand on the CDC statements regarding Salmonella in backyard flocks, many of these precautions should also be applied when going to a feed or retail store that offers baby chickens, turkeys and/or ducks for purchase. Many stores are now enclosing the birds in an effort to discourage handling, but it is still a good idea to wash and/or sanitize your hands prior to leaving the store.

Additionally, take extra precautions when cooking or handling raw chicken. Try to limit the exposure of raw chicken to temperatures above 40 degrees Fahrenheit (e.g., leaving raw chicken out on the kitchen counter). Always cook poultry thoroughly — use a meat thermometer to ensure that the proper temperature is met — and disinfect surfaces where meat was stored or prepared. The safe internal temperature for cooked chicken is 165° Fahrenheit (75° Celsius).

Foot rot is defined as a contagious disease in cloven-hoofed mammals that causes inflammation of the foot and subsequent lameness (Blood and Radositis, 1989). Lameness in all sectors of the beef industry can lead to decreased performance. It is estimated that approximately 20% of lameness in all cattle — dairy and beef — is attributed to foot rot (Step, et al., 2016). However, in the beef industry alone, it is estimated that closer to 75% of all diagnosed lameness in cattle is attributed to foot rot (Currin et al., 2009). Cattle in the feedlot have been reported to have close to half a pound lower average daily gains while they are combating foot rot (Brazzle, 1993). Therefore, foot rot represents a significant economic loss to the industry due to decreased performance.

What causes foot rot?

Bacteria are responsible for the cause of foot rot. The main foot rot-causing bacteria in cattle is Fusobacterium necrophorum, a ubiquitous bacterium found in the environment. Researchers have isolated it on the surface of healthy feet, in the rumen and in the feces of beef cattle. Other bacteria that are present on healthy feet can increase the virulence of F. necrophorum and, therefore, increase the incidence of foot rot (Currin et al., 2009). It is not until there is an injury to the foot — caused by walking on rough surfaces or standing in wet, damp and/or muddy conditions, resulting in a weakening of the foot tissues — that the bacteria sets in and wreaks havoc on the foot. Another common cause of foot rot is when cattle quickly go from wet conditions to dry conditions. This can cause the skin to become chapped and cracked, giving F. necrophorum a chance to enter the tissues of the hoof. Mineral deficiencies in zinc, selenium and copper are also known causes of foot rot (NRC, 2017). Because foot rot can be caused by a ubiquitous bacterium, it is not considered contagious.

Symptoms of foot rot

Clinical foot rot will present with the following symptoms:

1. Extreme pain, leading to the sudden onset of lameness
2. Elevated body temperature
3. Bilateral swelling of the interdigital tissues, around the hairline and coronary band of the hoof. The swelling may lead to greater-than-normal separation of the claws
4. Necrotic lesions in the interdigital space, with a foul odor
5. Decreased feed intake

These symptoms can be similar to the symptoms of other foot issues that are common in beef cattle. For example, digital dermatitis, commonly referred to as hairy heel wart, is often mistaken for foot rot when cattle become lame (Step et al., 2016). However, digital dermatitis only affects the skin in the heel bulb area and up to the area of the dew-claw. Digital dermatitis also does not produce a foul odor, is more centralized and is contagious.

How to treat foot rot

Once the proper diagnosis is made, foot rot can be treated. Treatment for foot rot is most successful when completed early, toward the beginning of its onset. The most common method of treatment is via tetracycline antibiotics (Currin et al., 2016). It is crucial to consult a local veterinarian for recommendations about antibiotics and the proper dosage levels. Other common treatments include rubbing a sterilized rope or twine between the animal’s toes to remove the necrotic tissue, followed by applying a topical antimicrobial and simply keeping the foot clean and dry while antibiotic treatment is given.

There are practices that can help reduce the risk of foot rot in a herd. For example, if caused by wet and muddy conditions, ensure proper drainage and the sloping of pastures or barns, such that moisture doesn’t collect in locations where cattle often congregate. Additionally, smoothing rough areas and ensuring that pastures and pens are kept clear of sharp debris that can cause abrasions or scratches to the hooves can help keep foot rot at bay. Simply ensuring that cattle are fed proper levels of minerals has shown to reduce the incidence of foot rot. Zinc is known to be critical for maintaining the integrity of the skin and hoof (NRC, 2016); thus, zinc should be fed at proper levels — and even elevated levels, if foot rot is known to be a common issue (Kellems and Church, 2010). Organic complexes of zinc are commonly included in beef diets at normal levels. However, with the increased bioavailibity of zinc in its organic form, it is wise to ensure the proper zinc status of the herd to reduce the incidence of foot rot. Although iodine is not known to be a mineral involved directly in foot integrity, dietary EDDI, a common source of iodine used in mineral supplements and premixes, has shown to be beneficial in the prevention of foot rot.

Foot rot is a significant cause of lameness in beef cattle and can result in a major economic and production loss in some herds. Although foot rot-causing bacteria can be found everywhere and are sometimes unavoidable, quick treatment early on and practicing proper pasture and pen maintenance can help to reduce the chances of clinical foot rot in beef cattle. Also, making sure the zinc and iodine levels are properly maintained during all stages of production in forms such as EDDI and organic complexes such as Alltech’s Bioplex Zinc can maximize protection against foot rot.

Technology can help us manage busy schedules, stay on track with our fitness goals and connect with family and friends who live far away. In many ways, the newest tech gadgets can also be advantageous for our pets — but do they have any downsides? In humans, for example, too much time spent engaged with our phones can be detrimental to our mental and physical health. So, is there such a thing as too much technology for our pets?

In order to live their best lives, pets only require the right nutrition, care, exercise and attention. While technology will never replace a cat curled up in her owner’s lap or a devoted canine companion lying at his owner’s feet, it can simplify life with pets in several ways.

1. Nutrition: An estimated 60% of cats and 56% of dogs in the U.S. are overweight or obese. As such, a tech tool for weight management can be a real life-changer for chubby pets. Smart feeders and smart scales can help with portion control. Smart feeders for multi-pet families ensure that each pet is given the right amount of food and can also help cut down on fights over the dinner bowl. Smart water bowls encourage drinking and are a simple way to monitor whether or not pets with medical conditions are drinking enough.
2. Veterinary care: Apps can help connect pet parents with vets and other healthcare providers. Visits to the veterinary clinic can be both stressful and inconvenient, but a virtual visit or text chat with a vet can eliminate some of those issues. At-home doggy DNA tests can unravel the mystery of a mixed-breed dog’s genetic makeup, allowing owners to learn more about the potential health issues linked to their pet’s breed and background. Microbiome test kits identify the type of microorganisms living in our pet’s digestive tract, giving us further insight into their health, immunity and behavior.
3. Exercise: GPS devices and step trackers can tell us just how active our pets have been during the day. Are they couch potatoes, or are they running laps around the living room? This data can help us determine whether a 30-minute walk will be enough to wear out our pup at the end of the day or if we will need to spend more time at the dog park. This technology can also help us locate our pets if they decide to go on an unapproved solo adventure.
4. Cameras: Who doesn’t want to see what their pets get up to when they’re left at home alone? Whether it’s separation anxiety — in the pet or the human — or a burning desire to help your fur-baby become the next viral video star, smart cameras give us a peek at what our pets do when we’re not around. They can also help keep our pets safe in the event of a fire or break-in. And who knows? You may even catch them doing a little counter-surfing — in which case, you can offer them a quick scolding via video chat.

Pet technology certainly has its advantages: smart cameras help keep both our pets and our homes safe, walking around the block in order to earn a badge on an app is still exercise, and texting with your vet can provide peace of mind. Ultimately, however, we should remember that pets are pretty low-tech; their biggest desire is usually just the pleasure of our company. Technology will only continue to improve and make our lives easier — for example, autonomous robots designed to automatically scoop dog poop are currently in the works. This begs the question, though: Will we eventually be plagued with too much data from our pets? All we know right now is that this is a possibility. In the end, owners will be best-served to remember that an app, a smart bowl or several hours of livestream video will never replace what we love most about our pets and the joy we feel in caring for them.

Tests of varying scientific nature and credibility are widely alleged to have the ability to differentiate between good and bad organic trace minerals (OTMs). The basic parameters that can be analyzed include mineral percentage, nitrogen-to-mineral ratio, percent of bound mineral, molecular weight, bioavailability and stability. While some of these analyses can provide meaningful and valuable information about defined or individual products, understanding the limitations of these tests is critical if they are to be successfully applied in the assessment of OTMs.

Mineral percentage

Accurate quantification of the total mineral content of OTMs is routinely used by all manufacturers, and cost comparisons between OTMs will consider this when calculating their relative value. Total mineral content, however, gives no information regarding OTM bioavailability and, as such, is limited in terms of calculating the true relative value of a product.

Nitrogen-to-metal ratio

Calculating the molar ratio of nitrogen to metal can be a useful way to assess glycine-based chelates. When assessing more complex products, such as proteinates, the nitrogen-to-mineral ratio will not give an accurate reflection of the true potential for mineral bonding. More complex amino acids can bind metal atoms through their side chains via sulfur and oxygen atoms. As there is no involvement of nitrogen in this side chain bonding, it is possible to underestimate the potential for binding by only considering the nitrogen-to mineral ratio. The nitrogen content of various products can also be artificially inflated, giving the false impression of a product with high nitrogen-to-mineral ratio.

Solubility

It is often asserted that an OTM must be soluble to be bioavailable, but many peer-reviewed publications have shown that insoluble OTMs have the potential to be more bioavailable than their soluble counterparts. An evaluation of OTM solubility will be of little benefit unless one considers the effects of the digestive processes and the changing pH environment within the GI tract.

Molecular weight

Numerous claims have been made about comparing OTMs based on size, and these claims erroneously indicate that a smaller-sized bonding group creates a more stable and more bioavailable OTM. Correlating the molecular weight of an OTM with its stability constant indicates quite clearly that, rather than size being of critical importance in generating a stable OTM, the type of bonding group is of far greater significance.  

Bioavailability

In vitro lab-based assays, which attempt to assess bioavailability, have been developed, making use of cell culture-based assay systems that can determine the transfer and uptake of minerals across cellular membranes. These techniques, however, can’t accurately reflect the influence of digestion on the OTM. As such, their value when comparing different products is limited.

Stability

When we talk about the stability of OTMs, we are referring to the bond strength that exists between the bonding group and the mineral; the greater the bond strength, the more stable the product. Polarography can be used to assess the bond strength of OTMs — but polarography is only suitable to test materials in solution and can only assess the soluble fraction of organic mineral products. OTMs are increasingly solubilised as a result of the in vivo conditions of the GI tract, so the results of the polarographic tests alone should be interpreted with caution.

Percent of bound mineral

Historically, determining the percent of bound mineral required utilizing filtration through a low-molecular-weight membrane. The mineral retained behind the filter was assumed to be bound, while the mineral in the filtrate (solution) was assumed to be unbound. Such methods, however, are subject to manipulation, as changing the pH of the buffer can cause precipitation and lead to false estimates of the true bound mineral percentage.

The only validated assays that fully quantitate the bound mineral level of an OTM utilize techniques known as ATR-FTIR (attenuated total reflectance Fourier transform infrared) and PXRD (power X-ray diffraction) and were developed by researchers at Alltech’s European Bioscience Centre.

The first assay uses a form of infrared (IR) spectroscopy to measure the bound mineral percentage, whereas the second assay uses a form of crystallography to measure the unbound mineral level. These two assays are complementary to each other, and both are peer-reviewed and published. In the case of the IR assay, this was independently validated and verified by the Central Reference Laboratory (CRL), which reports directly to the European Food Safety Authority (EFSA).

Conclusion

While simple tests based on mineral percentage, nitrogen-to-mineral ratio, molecular weight, bioavailability and stability are used by different manufacturers, these tests only provide limited information about individual products and are not suitable for comparing different classes of product. If products will continue to be compared through these tests, understanding their limitations is critical.

The only validated assays to assess mineral chelation are based on the use of techniques known as ATR-FTIR and PXRD and were developed and validated by researchers at Alltech’s European Bioscience Centre.

Today, most of us rely heavily on technology to simplify all aspects of our lives, from communication to organization. On average, Americans check their smartphones once every 12 minutes, and many report experiencing anxiety or feeling unsettled when their phones are off or out of reach. This makes sense; our phones often contain apps that help us juggle the endless activities and commotion surrounding our daily lives. And the options are seemingly endless — we have apps to tell us about the weather, to help us keep track of our fitness and finances, and even to build our grocery lists.

Considering how integral this technology is to modern life, it comes as no surprise that apps are also starting to make an impact on the horse world. There are a variety of options available that cater to every equestrian, from the casual pleasure rider to the broodmare manager at a top Thoroughbred farm. No matter who they are designed for, these apps often share one common goal: to simplify horse care and provide instant access to important information.  

Apps for tracking your ride

Whether you are a high-level competitor showing horses at the upper levels or a backyard pleasure rider out for a weekend trail ride, there are apps available to improve your ride. For instance, the Hylofit and equinITy apps help monitor fitness by tracking the heart rates of both horse and rider; they also monitor performance data to allow for the real-time assessment of performance and recovery during workouts. This rapid and continuous feedback allows riders and trainers to adjust their conditioning programs to ensure that their elite equine athletes will achieve optimal fitness.

For the pleasure rider, apps like Horse Rider SOS and Ride With Me act as an extra safety measure, especially for those who ride alone or in unfamiliar areas. These apps can provide peace of mind by monitoring your movements during a ride. When the app notices a period of inactivity, which could be the result of a dangerous situation — for instance, if the rider has fallen and cannot call for help — the app will alert the rider’s predetermined emergency contacts and share the rider’s location.  

Apps for horse health

The days of frantically trying to remember when your horse was last shod or when you are next scheduled to see the vet are over, thanks to apps like Horse Keeper and Horse Health Tracker. These apps allow you to access your horse’s health information — from their body weight to their vaccination records — in a single swipe. Both apps monitor weight and body condition, allowing you to keep notes about the diets of individual horses. They can even sync with your smartphone calendar to provide you with reminders about upcoming healthcare appointments, and they allow you to share this data with other users. And if you become aware of an issue or a problem, an app like Horse Side Vet Guide^® can give you access to information and practical advice, which could be helpful to have on-hand prior to contacting your vet.

Apps for barn management

Along with these apps for riding and tracking horse heath, there are other apps to help equine professionals run their businesses more efficiently. The University of Minnesota’s Hay Price Calculator app provides an easy way to compare hay prices by calculating the price per ton of baled hay. The PonyApp allows barn managers to track their horses’ daily activities, manage expenses and even add reminders about their stable, while also providing industry news and information. For the active trainer working with multiple students and horses, apps like BarnManager and StableSecretary can help maintain plans for both the short term (e.g., lesson scheduling) and the long term (e.g., yearly competition goals) — and this information can also be accessed by clients.

Looking for something more particular or focused than the previously mentioned apps? There are endless options, with new apps being released almost daily. For the international competitor, the FEI RuleApp provides on-the-go access to rules and regulations. For the racing enthusiast, Equibase Today’s Racing allows you to track your favorite racehorses in your very own virtual stable. For those who simply want to connect with other horse enthusiasts, there are options like The Equestrian App or Huufe: For Equestrians, which serve as social media platforms designed exclusively for equestrians. No matter what you’re looking for, you are sure to find something useful, thanks to the many apps tailored to nearly every aspect of equestrian life.

There are several opportunities to increase both feed efficiency and weight gain with creep feeds. Just as cattle genetics and management practices have advanced over the last several generations, nutritional knowledge and practices have evolved. This has allowed calves to continually improve, meeting the increasing demands of cattle producers and consumers alike.

Previously, protein and energy were the primary nutrients that nutritionists balanced in nursing calf diets. Now we can add feed additives (specifically yeast and yeast byproducts) and provide bioavailable trace minerals (organically sourced) to further advance the benefits of supplementing young cattle.

Leading the way in yeast technology

Alltech has more than 35 years of experience and is a leader in providing yeast technology based on research from both laboratory and animal production settings. Alltech’s Yea-Sacc® Extra contains a yeast culture specifically selected for their influence on animal performance. Yea-Sacc^® Extra provides the nutritional platform needed to enhance fiber digestion and stabilize ruminal function and pH.

Sel-Plex^® is Alltech’s proprietary form of selenium-enriched yeast and is the first European Union-approved and U.S. Food and Drug Administration-reviewed form of selenium-enriched yeast. Supported by more than 19 years of research, Sel-Plex is also the most proven form of selenium-enriched yeast. Alltech is currently the world's largest producer of natural selenium.

Providing a competitive advantage

Yeast culture and yeast cell wall components are effective products that have been fed to cattle for years and have been shown to exhibit a variety of beneficial properties that positively impact animal performance and health. Production applications of yeast cultures and yeast cell wall components include use in the diets of both low- and high-stress cattle, inclusion in creep feeds and inclusion in feeds for conventional, natural and organic production systems. Their components have proven beneficial in improving rumen health, stimulating the immune system, protecting against harmful bacteria such as E. coli and Salmonella, and promoting growth without the use of antibiotics.

More specifically, yeast culture stimulates digestive microflora, which in turn positively affects dry matter intake, rumen pH and nutrient digestibility. Yeast culture complements and stimulates the growth of ruminal cellulolytic or fiber-digesting bacteria. This leads to an increase in the rate and efficiency of ruminal fermentation. These microbial populations actively break down feedstuffs and help make more nutrients available to the calf for its growth and immune system. An increase in microbial protein can also be realized due to the stimulation of rumen fermentation and is readily available to calves as an excellent source of dietary protein. Because the animal’s appetite is stimulated, stress is reduced and a more consistent dry matter intake is maintained.

Proven results

Research reveals that daily gain and feed efficiency was improved in 21 out of 23 cattle feeding trials (91 percent response). Approximately 2,500 head of cattle were involved in the trials, and the levels of response were such that the net economic return was approximately 10 cents per head per day on feed.

In pasture situations, by including yeast culture in a free-choice creep feed, it has been shown that increased digestibility results in better forage intake and forage utilization by the animal. A three-year trial at The Ohio State University confirmed that providing yeast culture to grazing beef cattle can produce heavier calves at weaning. Their results indicated that including yeast in cattle diets produced calves that averaged 16.2 pounds heavier weaning weight. Another research facility has reported that there may also be benefits related to feeding yeast culture in rations containing ethanol co-products. The studies indicate yeast culture contains nutritional metabolites that co-products lose during the ethanol process.

Benefits of including yeast in nursing calf diets:

• Promotes digestion and utilization of nutrients
• Reduces fluctuation in pH and keeps rumen microbes steadily active, which speeds feed digestion and rumen turnover, allowing greater intake
• Promotes the growth of fiber-digesting bacteria in the rumen, thereby supporting the rate and extent of forage breakdown
• Stimulates activity of the bacteria that convert lactic acid to propionic acid
• Promotes rumen stability, avoiding the wide variations in rumen pH that interfere with fiber digestion and feed intake
• Provides consistent and highly cost-effective returns through greater performance
• Optimizes animal performance
• Supports mineral retention

In this seven-part series, Alltech Crop Science looks at esca and natural-based solutions for the disease.

Esca, a wood disease affecting grapes all over the world, is one of the biggest modern threats to grape production. Esca is a complex disease involving several different fungi. It attacks the main vine of the plant and can destroy it within a few days; there is no questioning the unstoppable pace at which this disease progresses.

Esca is one of the oldest-known diseases to afflict grape vines, having been noted by the Greeks and Romans and damaging vineyards quite heavily in the early 1900s. In twentieth-century France, more than 5% of vines were killed by esca each year. Because the disease grows at a slow but progressive pace, even the larger, well-established vineyards could be totally destroyed by esca in 15 to 20 years.

Esca was first successfully controlled in 1903, when sodium arsenite was used as an insecticide on grapes and quickly proved its ability to limit esca and other wood diseases. In fact, thanks to the use of sodium arsenite, research on the disease effectively stopped in 1920 — only to begin again in 1980, when a potential ban on the product was discussed.

Sodium arsenite, which was noted as being highly toxic and carcinogenic in 1987, was banned in France in 2001 and by the rest of Europe in 2003. Subsequently, grape growers have seen a re-emergence of esca, and, since 2001, 6–7% of vines must be replaced annually. Additionally, along with the traditional form of esca, a new form appeared — an “apoplectic” form that can cause the vine to dry up entirely within the first few hours of showing symptoms.

Today, there are no registered chemical or biological solutions for mitigating this disease. Studying and developing traditional solutions for combatting esca are difficult because of its complexity.

Esca impacts producers economically on multiple levels: the use of prophylactic measures (of debatable efficacy) can increase costs, while pulled-out vines, reduced yields and money spent on replantation can reduce income.

France, for example, estimates that 11% of the nation’s total number of grape vines are non-productive as a result of esca. Between 2003 (when sodium arsenate was prohibited there) and 2007, Spain saw the number of affected vineyards grow from 1.8% to 10.5%. This rate continues its upward trend — and epidemiological studies carried out in Tuscany, Marche, Abruzzi, Apulia and Sicily showed that, in regions like central and southern Italy, among others, the incidence of esca has reached an extreme 60–80% in older vineyards.

Alltech Crop Science explores natural-based solutions for esca

Alltech Crop Science, a global leader in natural-based, innovative solutions, is exploring alternative programs to help farmers protect their vines. Our global research centers and alliances, particularly in Spain, are leading the charge to solve this problem — and have already seen promising initial results.

For many, fall calving lies in the near future. Have you considered whether your cowherd’s summer mineral program is up to par? Implementing a proper mineral program is essential, as it can help determine the best way to maintain optimal reproduction with early conception rates while also boosting calf health and growth. We only get one calf per cow per year, so if there are any missteps in meeting our cow reproduction and calf growth goals, it will be a long time before corrections or improvements can be made.

During the late summer and into the early fall, forage quality is declining as the cow’s requirements are increasing for fall calving. Delivering minerals during this time is crucial in order to produce a healthy calf and ensure that the cow has what she needs to combat any stressors and to rebreed in time. For spring-calving herds, the period when calves are getting pulled and weaned is when the cow’s nutrient requirements are lowest; however, a proper mineral program is still necessary to provide for both the cow and her developing calf throughout the year.

Summer mineral programs

When considering a mineral program, bags and mineral feeders likely spring to mind, as these options have historically been used often and to good results. You may want to consider, however, thinking a little more deeply about some other summer mineral options that could help you stay on top of your herd’s nutrition program without the fuss and potential losses associated with dry granular mineral delivery. For instance, compared to bagged minerals, there are many inherent benefits provided by low-moisture blocks like CRYSTALYX low-moisture block mineral supplements.

Two of the biggest advantages of CRYSTALYX mineral supplements are their palatability and the uniformity of intake they ensure across all cattle within a pasture. Our research has demonstrated that more than 90% of cattle will frequent a CRYSTALYX mineral supplement, versus the roughly 60% of cattle that frequent an area where bagged minerals are available.

It is an undisputable fact that if your cows don’t eat the vitamin/mineral supplement you provide, they will not be able to capitalize on the additional nutritional benefits offered by that supplement. Reaching 30% more cattle within a herd helps ensure that nearly all of your cattle are receiving the added nutrients that encourage optimal performance. This is, without a doubt, the main reason that producers look to CRYSTALYX to help efficiently deliver their summer minerals.

That is certainly not the end of the list of benefits CRYSTALYX supplements can provide. There are a great deal of manufacturing processes and ingredients involved in creating a weatherized, bagged mineral that won’t blow away in the wind, wash down the creek in the rain or simply turn to stone after a downpour. What better weatherproof mineral could you offer than what already comes with CRYSTALYX?

CRYSTALYX low-moisture blocks are unaffected by wind or rain; cattle will simply slurp down any moisture that accumulates on the surface. And what could be more appealing to cows than a good-old consumption-regulated, low-moisture molasses block? There are a host of different intake limiters, encouragers and regulators associated with bagged vitamin/mineral products — but when cows actually want to consume your vitamin/mineral supplement presented in block form, they become unnecessary, as the nutrition is encased in a highly palatable, uniformly blended, dehydrated molasses block that keeps intake in check.

Let’s not forget how the minerals and vitamins are encased in a dehydrated molasses matrix, which is hugely beneficial, as it separates — and virtually eliminates — the reactivity that often exists between minerals and vitamins. Our observations have consistently revealed almost zero vitamin degradation with CRYSTALYX products when measured for up to and even beyond one year. This is certainly not the case with bagged minerals; harmful oxidative reactions begin to take place once the ingredients are mixed together, eventually destroying the vitamin potency.

One thing to remember when managing intake with CRYSTALYX mineral formulations is that the head count per container must be scaled up compared to the protein formulations. Follow the label recommendations, but generally, more cows per container — such as 40 to 60 head per barrel — should be considered to arrive at a 4-ounce intake. Compare this to our typical recommendation of 20 to 30 head for protein products, which are typically consumed in the 0.5- to 1-pound daily intake range.

Mineral feeders: Who needs them?

Upfront equipment costs are one thing, but continued maintenance expenses are seemingly never-ending. Bulls are always looking for some sort of recreational equipment to rough up, and feeders are common targets. There are plenty of creative feeding methods for providing loose minerals. Some producers make it sort of a puzzle that cows must figure out in order to access the mineral — which can really make you wonder just how many cows are actually courageous or creative enough to put their heads into these feeding stations. CRYSTALYX supplements come with their own container — and if you request that they be provided in the degradable BioBarrel^®, you don’t even have to go out and pick them up; they just degrade away into the environment. It doesn’t get much easier or more environmentally responsible than that.

A CRYSTALYX mineral program to fit your needs

If you’re not yet convinced to take a fresh look at how you provide vitamin and mineral supplementation to your cow herd, stop by your nearest CRYSTALYX dealer to get the full scoop on how our mineral products can add value to both your cow herd and calf crop, thereby increasing your operational returns. When technology arrives that can take us light-years ahead, we should adopt it and make it the norm. Providing proper vitamin and mineral delivery on-pasture is as easy as finding the right CRYSTALYX product to meets your cows’ needs.

Fetal programming, also known as “developmental programming,” has been a hot topic for a number of years now. When we consider fetal programming from a nutritional perspective, we think of the lasting impacts gestational maternal nutrition can have on calves. I have often heard farmers and ranchers say, “If you take care of your cows, they will take care of you,” and this certainly rings true in this instance.

We often think about fetal programming during late gestation. Naturally, we begin thinking about the upcoming calving season after last year’s calves are weaned. We know that nearly 70% of fetal growth occurs during the last trimester — but for a calf to be able to grow at an exponential rate during that time and remain healthy during its postnatal life (which will correlate to increased performance and profitability), giving it a prenatal head start during early gestation will be most beneficial.

Unfortunately, however, maintaining a focus on nutrition often gets put on the back burner during early pregnancy. After all, there’s a lot to keep up with in the summer! Cows and bulls are turned out on grass, we’re busy with breeding, and we get caught up baling forages to feed cows with in the winter. You may think that the cows are doing just fine nutritionally, but they — and their developing calves — might be missing out on more than you realize.

Get with the (fetal) program

Although fetal nutrient requirements are minimal during early and mid-gestation (making up less than 12 percent of the cow’s total requirements), from a production standpoint, gestation begins exactly when the cow’s nutrient requirements are greatest, due to the increased demands of lactation.

The placenta and many vital fetal organs develop during early gestation, which continues up to approximately day 90 in cattle. The placenta is responsible for conveying all of the nutrients and oxygen to the growing and developing calf; it also removes waste products. The placental formation in early gestation is crucial for optimizing vascularity and nutrient transfer to maximize blood flow, which is important for the calf’s overall growth. Research measuring the placenta and studying its effects on gestation has shown that nutrient restriction during early gestation can continue to negatively impact the animal throughout the entirety of gestation, even if the cow is provided with their nutritional requirements during late gestation. The impact of restricting nutrients early on includes smaller placenta sizes and decreased blood flow to the calf (Vonnahme et al., 2007, 2013).

Along with the placenta, the calf’s organs also develop during early pregnancy. Cells are dividing at this time, and this early formation of the organ system is crucial for the calf once it is born. These developing organs — such as the lungs and the gastrointestinal tract — are necessary not only for survival, but also for reproduction and the growth of muscle cells. Studies show that nutrient restriction to the cow during this phase can negatively impact organ development and productivity later in the calf’s life; in other words, restricting the cow also restricts the calf’s genetic potential. Genetic selection happens when the producer is making mating decisions, but you can program the calf during gestation to help increase the profitability of your genetics by providing ideal growing conditions. You have worked too hard with too many generations of your herd to take a step back in calf performance potential by not providing the necessary nutrients during gestation.

In order for these vital organs to develop properly — and to maximize your calves’ genetic potential — make sure your gestating cows don’t run short of critical nutrients, like macro and trace minerals, vitamins and protein. These nutrients generally must be delivered to the cow in forms that go beyond simple pasture forages. An easy way to ensure that these nutrients are provided is through a self-fed supplement, such as CRYSTALYX^® Brand Supplements, which are formulated with Alltech’s organic Bioplex^®  trace minerals.

A simple way to provide supplementation

As we wrap up the breeding season and get closer to the fall season, pasture conditions and forage quality often begin to decline. We should keep in mind that this can be a stressful time of year not only for us, but also for our animals. Consider what your cows are consuming and think about whether they might benefit from supplementation, beginning now and continuing through early gestation and beyond. CRYSTALYX Brand Supplements are a simple solution to make sure that your cows are consuming the nutrients that both they and the calves by their side and in utero need. 

Let’s face it: the summer months are a busy time for us all. Whether you are getting things done around the farm or ranch, catching up with friends and family, or just trying to stay cool, your cows out on pasture may not be getting as much attention as they need. After all, they can’t take any time off during the critical period of early gestation. Fortunately, you can minimize time and labor — and give yourself peace of mind — by putting out a self-fed CRYSTALYX barrel, which will be available to your cows around the clock. Your cows will essentially be taking care of themselves, and by raising better-performing, more profitable calves, ultimately, they will also be taking care of you.
