Aggressive behavior in pigs — whether it is tail-, flank-, ear- or vulva-biting — is a frustrating management problem, leading to costly losses.  Incidents of tail-biting, in particular, are among the top behavioral problems in gilt development units (GDUs) and grow-finish pigs that can lead to economic losses due to reductions in gain, secondary infections, death or carcass condemnations.

What are the causes of tail-biting in pigs?

Studies have shown that pigs are attracted to the taste and sight of blood, and if a pig draws blood from accidentally biting a pen-mate’s tail, doing so could elicit the negative behavior in that individual pig or even spread to the entire group of pigs. However, natural behavior is only one piece of the puzzle. Numerous other factors can increase the prevalence of tail-biting, such as environmental stressors (e.g., temperature variation, lighting, ventilation, etc.), dietary issues and health challenges.

Four tips on how to prevent tail-biting in pigs

1. Start with the basics: Feed, water, ventilation, temperature and stocking density  

• Feed: Providing ready access to feed is essential for optimizing average daily gains. Conversely, restriction of or inadequate access to feed will cause slower growth and can contribute to aggressive behavior, such as tail-biting. Feed restriction is most commonly caused by out-of-feed events that are the result of equipment malfunctions, feed bridging or feed management errors. The second-most common cause of feed restriction is feeder settings being adjusted too tightly.
• Water: Just as with feed, it is important to provide ready access to drinking water. Restricting the water intake of pigs can lead to reduced feed intakes and may also contribute to aggressive behavior. Make sure all of the pigs have enough water access points and that the flow rate is adequate enough to meet their water needs.
• Ventilation: Poor ventilation, especially in the late fall and winter months, can quickly induce aggressive behaviors. Make sure the ventilation is adequate enough to at least remove pit gasses from your facility. Poor air quality in barns irritates animals and is a major catalyst accelerating aggression in pigs.
• Temperature: In warmer months, heat stress is of great concern and is something that barn managers and employees should keep an eye on. When pigs reach their upper critical temperature, they begin to experience heat stress, which can trigger negative behaviors, such as tail-biting.
• Stocking density: Overstocking induces extra stress in animals due to the increased competition for feed and water resources in the pen. As such, it is critically important to relieve stocking density by evenly distributing pigs throughout all of the pens. Limited space in pens is a common trigger for tail-biting.

2. Provide balanced nutrition

Nutritional imbalances or improperly balanced diets are contributing factors that can increase the likelihood of aggressive behavior. Under-budgeting and/or under-formulating lysine for high lean growth genetics can lead to vice behavior by restricting the genetic growth potential of the animal. Inadequate sodium in the diet can also lead to aggressive behavior.

3. Look for signs of health challenges

Significant viral challenges, like PRRS and the flu, can lead to increased incidences of aggressive behavior in pigs. Consult your veterinarian on the best course of action to relieve any health challenges in your operation.

4. Keep calm and entertain

Pigs are naturally very curious animals that utilize their mouths as a means of exploring and learning more about their environment. As such, providing enrichment that is stimulating and that biologically relieves stress is crucial.

The AllBite block, from Hubbard Feeds and Alltech, is a molasses-based block designed to discourage tail-biting and other aggressive vice behaviors. AllBite adds a new stimulus to the pigs’ environment, thus allowing pigs to exhibit foraging behaviors and to bite and chew on the block instead of their pen-mates. 

AllBite combats aggressive behavior through two mechanisms: it contains biologically active calming agents that reduce stress within the pen, and it is delivered in a form that provides a sensory stimulus to a group of pigs. Researched and tested in the field, AllBite has a 93% success rate in reducing or stopping tail-biting. The key is early identification, followed by the introduction of AllBite into pens where tail-biting and other aggressive behaviors are occurring.

While changing diets to mitigate negative behaviors is a common practice, dietary changes are often not implemented early enough to effectively prevent those negative behaviors from manifesting. Also, most vice behaviors only affect a small group within a larger population, so changing diets can sometimes become costly. With its unique delivery system, AllBite addresses both issues, since blocks can be placed in pens as soon as tail-biting occurs, and the blocks are only supplemented in the pens where pigs are exhibiting vice behaviors.

During a tail-biting outbreak, it is important to try and identify the biters and treat and/or remove the bitten pigs to prevent the behavior from spreading to other pigs. The root of vice and aggressive behavior is multi-factorial, and the mechanisms of this behavior are not fully understood. However, a quick response is key to helping prevent or stop vice behaviors in pigs. Tail-biting is a universal concern, and, as animal caretakers, maintaining the welfare of our pigs is our daily responsibility.

Meeting the protein requirements and improving nitrogen efficiency in cows under different physiological conditions can become more precise with the use of this additional  tool for diet formulation

[DUNBOYNE, Ireland and ESPOO, Finland] – An innovative laboratory fermentation method for assessing the ruminal breakdown of dietary protein ingredients has been created by Alltech and Alimetrics Research. The novel technique was developed to evaluate feed protein sources and involves measuring the proportion of certain amino acids that is converted to specific end products over 24 hours.

Scientists from Alltech and Alimetrics collaborated on the study, which has been published in the scientific journal Frontiers in Veterinary Science and compares the rumen degradability and effects on rumen fermentation of three protein sources: whey protein, soybean meal and yeast-derived microbial protein.

The assessment of protein degradation in the rumen of live animals has historically proven difficult, and although analysis of overall protein can be done, tracking the origin of protein from a specific feed component cannot be done with great certainty. In addition, ruminants have a low overall efficiency of nitrogen utilisation, with between 70– 95% of the nitrogen in diets excreted in dung and urine, according to the Food and Agriculture Organization of the United Nations. The use of this novel in vitro technique can help to overcome such challenges as it allows protein sources to be ranked according to their degradability by rumen bacteria.

“When it comes to comparing protein sources, we believe this tool is particularly useful when some known and commonly used benchmark products, such as soybean meal, are included in a study,” said Dr. Juha Apajalahti, managing director at Alimetrics.

Data from the study indicate that the yeast-derived microbial protein was the most resistant of all three protein sources to being degraded in the rumen, with less than 15% of the amino acids of interest being converted to end products measured. Additionally, the study showed that the level of the protein breakdown product, ammonia, from yeast-derived microbial protein was able to be taken up by the rumen bacteria, reducing excess rumen ammonia accumulation. Evaluation of other parameters demonstrated that the yeast-derived microbial protein was able to extensively stimulate rumen fermentation to the same extent as soybean meal.

These data not only suggest that this novel method is suitable for assessing ruminal breakdown of protein feeds, but also that yeast-derived microbial protein could potentially provide a more sustainable, and equally suitable, alternative to products such as soybean meal.     

“In terms of research methodology, this provides us with a robust model for screening products, both for fermentation effects and the ability to bypass protein through the rumen,” said Matthew Smith, vice president at Alltech. “The findings from this study clearly demonstrate the value of our yeast-derived microbial protein in stimulating rumen fermentation and volatile fatty acid and microbial biomass production. The tool itself is one we can use in our own in vitro fermentation model, Alltech IFM™, to aid future development.”

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).

Over 50 mycotoxins can be tested for by the Alltech 37+ Laboratory

[DUNBOYNE, Ireland] New and emerging mycotoxins can now be analysed by the Alltech 37+^® Laboratory. In total, five new mycotoxins have been added to the testing panel, bringing the total number of detectable mycotoxins to 54. These new additions further increase the understanding of mycotoxin occurrence and the potential risk to animal performance.

Emerging mycotoxins refers to mycotoxins that are neither routinely analysed nor legislatively regulated. However, research has shown more evidence of their increasing incidence and potential toxicity to animals. The emerging mycotoxins analysed by Alltech 37+ include beauvericin; moniliformin; enniatins A, A1, B and B1; phomopsin A and alternariol. Fusaric acid also features in this emerging mycotoxin category.

“The Alltech 37+ mycotoxin analysis test is the cornerstone of the Alltech Mycotoxin Management program,” explained Nick Adams, global director, Mycotoxin Management, Alltech. “We now test for 54 mycotoxins. With this new analytical capability, Alltech is better equipped to understand how contaminated feedstuffs might impact animal performance and health.”

Due to their toxic properties, mycotoxins are a concern for livestock producers, as they can impact feed quality as well as animal health and performance. A world leader in mycotoxin management, Alltech’s 37+ test results provide a realistic picture of mycotoxin contamination in feed ingredients or total mixed rations, speeding up the process of diagnosis, and suggest effective remediation and help move toward an effective mycotoxin control plan.

“Since adding these mycotoxins to our analytical capabilities, we have already seen a high frequency of samples with these contaminants,” explained Dr. Patrick Ward, Ireland Analytical Services Laboratory manager, Alltech. “As we test more samples and accumulate more data, we will strengthen our understanding of these mycotoxins.”

Between Alltech’s 37+ mycotoxin analytical services laboratories in Lexington, Kentucky, and Dunboyne, Ireland, they have run over 30,000 samples, each searching for up to 54 mycotoxins in animal feed.

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.

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 

Yeast culture inclusion in creep feeds make them more nutritionally complete. If you would like to learn more about yeast, yeast cultures and Sel-Plex, take a look at these videos on alltech.com.
