A comprehensive biosecurity program is the first line of defense in keeping the pig farm safe from outside threats and risks. But what role does nutrition play, both in the sustainability of our food chain and how we reduce the risk of viral diseases in our pig populations around the world?

In a panel discussion at Alltech’s ONE Idea Conference, Dr. Barry Kerkaert, president of Pipestone Management, Dr. Scott Dee, director of applied research at Pipestone Veterinary Services and Dr. Jon De Jong, president of Pipestone Nutrition, discussed how a porcine epidemic diarrhea (PED) outbreak in their farms led to a surprising discovery about how it was transmitted and what they have done to help prevent future issues.

Feed as a risk for viral transmission

As people in livestock and agriculture know, a huge part of a farmer’s success depends on animal health. When a farm is challenged by diseases such as porcine reproductive and respiratory syndrome (PRRS) or PED, it is all-hands-on-deck to determine what caused the outbreak and stop it from spreading further.

When PED was first introduced into the United States in 2013, affected farms initially seemed to have no connections, whether animal, transport or people connection. Questions arose surrounding what was causing the virus to spread so rapidly. Then, in early 2014, four barns in the Pipestone system had an outbreak in under 24 hours, prompting an investigation that would eventually lead to a breakthrough discovery about the role of feed in viral transmission.

The feed mill connection

Part of Pipestone’s thorough investigation was looking into the feed mill. As they continued to dig deeper into how PED spread in these secluded farms, they found that the four farms all received feed out of the same batch from the same feed mill. However, other farms fed using the same mill with no disease issues were fed out of a different batch. Because of this discovery, Pipestone decided to pursue feed’s role in transmitting the virus aggressively. Dr. Scott Dee and Pipestone’s veterinary and nutrition teams quickly concluded that feed, based on their observations and collected data, was responsible for moving this virus throughout their farms. It was a monumental discovery — the first time in the history of veterinary medicine that the transmission of PED had been shown experimentally through feed.

Now, seven years later, new studies show that other viruses, such as PRRS, African swine fever (ASF), foot-and-mouth disease (FMD), hog cholera or classical swine fever (CSF) and Senecavirus (SVA), live in feed and provide even more evidence that feed ingredients represent a risk for transporting pathogens at domestic and global levels (Dee et al., 2018).

The cost of an outbreak: The financial and human toll

When thinking about disease outbreaks on their sow farms, Pipestone considered the cost to both the farm and the downstream flow. It is estimated that for their farms, with around 5,400 sows, a PRRS break would cost $1.5 million. The cost to include their preferred mitigant as part of their biosecurity program was approximately $0.30–0.40 per weaned pig.

“When I start thinking about mitigation, and we just do the math, $0.30 a weaned pig annualized off those sow farms, we need to prevent one PRRS break every 22 years from feed in order for that mitigation product really to be a breakeven, to pay for itself,” Dr. De Jong said, explaining how using their mitigant of choice was a no-brainer. “So, when we looked at it, it seemed like, geez, I sure think we can reduce at least one break in a 20-year timeframe with the use of a mitigant specifically targeting some of those higher-risk times of the year when we've got some cold weather up here in Minnesota and South Dakota.”

However, the financial toll of a disease outbreak is just a piece of the puzzle. When looking at a mitigation plan, farmers make decisions based on the health and safety of their pigs. Still, it is also vital to recognize an essential of sustainability: the employee — their health and attitude, which makes them want to come to work every day. When the animals are unhealthy, the team’s morale deteriorates, and that can result in higher turnover, usually leading to poorer results.

Biosecurity starts with feed safety

Does feed pose a disease contamination threat on a farm? Absolutely. Is it the leading risk or the only risk? Absolutely not. However, it is part of a biosecurity program that needs consideration and thought. While other factors contribute to disease risk, a comprehensive biosecurity program is one of the most important programs a farm can put in place. It acts as the farm’s guard to keep it safe from outside threats and risks, and the first line of defense starts with feed safety.

Aquaculture, in contrast with capture fisheries, has remained stable over the last few decades. The industry continues to grow and contribute to the increasing food supply for human consumption, reaching worldwide production of 80 million metric tons (Mt) in 2016. To sustain its growth, the aquaculture industry is highly dependent on commercial feed sources. The inclusion rate of traditionally used finite and expensive marine protein and fat sources from wild-caught fish (i.e., fishmeal and fish oil) in the diets of farm-raised fish species will continue to decline, and the industry has already shifted to crop-based raw materials to meet the rising demand for aquafeeds.

Fish require several carefully chosen raw materials to provide them with a healthy diet, but fish-based proteins are not essential. The industry has recognized this, and there are now many fish feeds with 0% fish-based protein ingredients and an industry average (FIFO Factor). Plant-based feed ingredients increasingly replace marine-based components, and therefore, an enhanced level of understanding of the nutritional quality of raw materials derived from plant sources is becoming increasingly crucial for aquafeeds. Moreover, the higher inclusion of less-expensive plant sources may introduce a series of anti-nutritional factors (e.g., protease inhibitors, phytates, saponins, glucosinolates, tannins, non-starch polysaccharides) and/or increase the occurrence of mycotoxins in fish feed; factors that may affect the quality and safety of aquafeeds.

Mycotoxins in aquaculture feed

Mycotoxins are fungi that can grow on crops during growth, harvest, processing or storage. The development of these fungi is climate-dependent and most commonly seen in tropical regions. In these climates, the fungi produce chemical compounds known as mycotoxins and can have a greater impact on animal health.

Fish farming is a diverse industry, and each aquaculture species will have different sensitivities to the impacts of mycotoxins. These can cause a reduction in performance — reduced growth and increased feed conversion ratio (FCR) — and increased disease susceptibility and mortality rates. As these issues can be attributed to other concerns, the risk can often be overlooked and underestimated in aquaculture.

Mycotoxins are mainly detected in plant-based feedstuffs, readily present in corn, wheat and soybean meal. Increasingly, the occurrence of mycotoxins has been reported in aquafeeds. There are over 50 different types of mycotoxins, but the most commonly known and most prevalent is deoxynivalenol (DON).

Effects of deoxynivalenol on the health and growth of farmed fish species

Accumulation of DON in fish can be harmful and impact their performance. In terms of occurrence and toxicity, DON has been characterized as the most high-risk mycotoxin in aquafeeds. Its effects include:

1. Ribotoxic stress response: DON binds to ribosomes, inducing a “ribotoxic stress response” that activates mitogen-activated protein kinases (MAPKs).

2. Oxidative stress: DON causes oxidative stress in cells by damaging mitochondria function, either through the excessive release of free radicals — including reactive oxygen species (ROS), which induce lipid peroxidation — or by decreasing the activity of antioxidant enzymes.

3. Impacting epithelial cells in the digestive tract: Predominantly, rapidly proliferating cells with a high protein turnover, such as immune cells, hepatocytes and epithelial cells of the digestive tract, are affected by DON.

4. Reduced growth rate: In Atlantic salmon diets, 3.7 mg/kg of DON resulted in a 20% reduction in feed intake, an 18% increase in FCR and a 31% reduction in specific growth rate. In white shrimp, DON levels of 0.5 and 1.0 ppm in the diet significantly reduced body weight and growth rate, while FCR and survival were not affected.

5. Decreased immune system response: Mycotoxins impair optimum animal performance by affecting intestinal, organ and immune systems. These, in turn, negatively impact overall performance and profitability.

6. Reduced feed intake: A study conducted by Woodward et al. (1983) showed that rainbow trout had a sharp taste acuity for DON. Their feed intake declined as the concentration of DON increased from 1–13 ppm of the diet, resulting in reduced growth and feed efficiency

The impacts will vary on many factors, including the quantity, feeding level, duration of exposure and aquatic species. A recent meta-analysis completed by Koletsi et al. (2021) highlights the risk of DON on feed intake and growth performance. In parallel, data was collected to quantify the risk of exposure in fish. The extent to which DON affects feed intake and growth performance was evaluated by employing a meta-analytical approach.

Having completed a full meta-analysis of the current research and trial data available for the aquaculture species, Koletsi et al. concluded that the current recommendation for the limit of DON in fish diets is too high and needs to be reviewed in order to protect the welfare of fish and maintain an economic advantage.

Preventing mycotoxins in aquaculture

Maintaining a good management system will help to control the mycotoxin risk. However, some mycotoxins remain stable, even after high-temperature extrusion processing. For this reason, additional steps should be taken to mitigate the risk. Alltech mycotoxin management tools, such as Alltech 37+® and Alltech® RAPIREAD, help farmers and feed producers identify their total mycotoxin risk (REQ). Evaluating risks associated with mycotoxins on animal performance and financial losses can be more rapid than ever before.

At this point, most of us know that the gut microbiome is an important component of overall health. With estimates asserting that mammals contain around 10 times more bacteria than cells in their bodies — and 1,000 more microbial genes — the importance of a healthy gut cannot be overstated.

While many of us have heard about prebiotics and probiotics for dogs and cats, the new term on the block is “synbiotics,” which are simply an effective and beneficial combination of pro- and prebiotics for cats and dogs. Current research shows that the right combination product could be a game changer in pet food diets.

How do prebiotics and probiotics for dogs and cats work together?

Here’s a quick refresher:

• Probiotics are consumable live microorganisms that have beneficial effects when fed in the appropriate concentrations.
• Prebiotics are fiber or fermented ingredients that pass through the GI tract undigested and positively influence the microbes in the gut.

In simple terms, probiotics are good bacteria, and prebiotics help feed those good gut bugs.

Synbiotics were created as specific combinations of pro- and prebiotics that work well together. Basically, synbiotics are selective strains of bacteria with specific prebiotics that best support those microbes.

Once in the body, synbiotics can act in various ways to support health.

What do prebiotics do in the body?

Upon being ingested, prebiotics pass through the animal’s stomach and small intestine without being broken down by hydrochloric acid or digestive enzymes. Once they reach the large intestine, prebiotics get to work as the “fuel” for the good bacteria in the gut.

Prebiotics work together with probiotics to maintain a delicate balance and diversity of organisms in the GI tract. As probiotics are fueled, the body reaps more benefits.

Additionally, as prebiotics are fermented and used by probiotics, short-chain fatty acids — such as butyrate and other postbiotics — are generated. These postbiotics are used by the cells of the GI tract as a nutrient source, which further contributes to a healthy gastrointestinal tract.

What do probiotics do in the body?

Different probiotic strains have different mechanisms of action in pets. Some examples of how probiotics can influence health include:

• Competing with and displacing bad bacteria in the GI tract by attaching to the intestinal lining
• Producing antimicrobial substances like fatty acids
• Inactivating toxins
• Up-regulating the production of beneficial metabolites
• Enhancing immune system function
• Supporting the integrity of intestinal epithelial cells

While many strains of probiotics are used in dogs and cats, some of the more common and widely researched include Enterococcus faecium, Lactobacillus acidophilus and Bifidobacterium spp. animalis.

Multiple studies have shown that the gut bacteria composition of dogs experiencing digestive diseases, such as chronic diarrhea and inflammatory bowel disease, is altered compared to the gut bacteria of healthy dogs, which suggests that probiotics for dogs with diarrhea and other dysbiosis-inducing conditions may be one solution for better health.

What benefits do synbiotics provide?

As stated above, the whole point of synbiotics is to create one combination product that provides a net benefit for the animal based on synergistic pre- and probiotics.

Research trials involving pre- and probiotics for cats and dogs that study the most effective mixture of strains are limited, and the results of the trials that have been conducted vary greatly due to the myriad ways to test changes in the gut microbiome, as well as the different concentrations of beneficial bacteria and fiber being offered and the timing of administration with respect to other foodstuffs or medications. That being said, let’s look at what we do know.

One study in healthy, trained sled dogs found that a synbiotic that included E. faecium, Bacillus coagulans, L. acidophilus, and multiple prebiotics and vitamins led to an increase in Lactobacillaceae bacteria and the concentration of butyrate, as well as a decrease in diarrhea. In cats with chronic diarrhea, administration of a proprietary synbiotic blend improved fecal scores significantly after only 21 days.

Several studies have investigated the use of synbiotics in cats in conjunction with clindamycin, an antibiotic known to induce significant GI changes and distress in both pets and humans. In one trial, the use of a synbiotic with clindamycin in previously healthy cats illustrated synbiotics’ potential ability to mitigate some loss of beneficial bacteria. Additionally, the cats receiving the synbiotic also seemed to have altered levels of polyamine synthesis. Polyamines aid in the repair of the intestinal lining and have anti-inflammatory properties, so this is particularly interesting and will require more research to fully understand.

While the science continues to evolve, what we already know for sure is that supporting the microbiome and continually improving the gut ingredients available for pets will be hugely important in differentiating pet food brands.

How to market synbiotics

Adding a winning combination of probiotics and prebiotics to pet food diets is not only advantageous for good gut health and an optimal pet immune system but could also be profitable for businesses.

With pet parents always looking for an “edge” for their pets, adding a custom combination product that fits your brand’s needs is crucial for brand awareness and recognition. In a crowded marketplace, the smallest ingredients in the bag are often the biggest market differentiators.

Additionally, in the human nutrition marketplace, the idea of synbiotics is becoming more and more mainstream, which means that people will soon be looking for this word on pet food packaging.

When marketing synbiotics to consumers, here a few tips:

1. Identify the main reason why your company chose these particular strains of bacteria and supportive fiber.
2. Boil your main “why” into less than 10 words for each strain or fiber source.
3. Educate consumers so that they understand why your brand has selected these particular ingredients and why what you are offering is different from other brands.
4. Communicate obsessively via your channels. If it feels like you are repeating the same language, then you are doing it right! Most people need to hear something at least seven times before it really solidifies as fact in their brains.

As a company founded on science, Alltech’s technologies continue to be researched as extensively as they have for the past 40 years. We can help identify the custom blend of ingredients that would best serve your pet food brand based on your unique needs, processing techniques and marketing strategies.

Okay, let’s get real: While nutrition is one of the most important ways to influence any animal’s health, feeding horses is not rocket science, and we tend to overcomplicate equine nutrition.

While performance horses often have more specific nutrient requirements than the average horse at maintenance, all horses have the same general needs, and keeping it simple when it comes to feeding is the best method for reaching maximum horse health.

Here, we will break it down step by step so that you can make sure your horses receive exactly what they need.

1. Determine your horses’ energy needs based on their exercise and training schedule.

Before we get ahead of ourselves, it is important to take an honest inventory of your horse’s training regimen. The key word here is “honest” — but we’ll get back to that in a moment.

According to The Nutrient Requirements of Horses (NRC), there are four categories of activity level and intensity:

• Light exercise: One to three hours per week of mostly walking and trotting.
• Moderate exercise: Three to five hours per week of mostly trotting, with some walking and cantering and some skilled work, like jumping, dressage, cutting or ranch work.
• Heavy exercise: Four to five hours per week of trotting, cantering, galloping and skilled work.
• Very heavy exercise: One hour per week of speed work and/or six to 12 hours per week.

Generally, the only horses that fit into the “very heavy” category are racehorses, elite endurance horses or three-day-eventing horses, while most other horses fit into the light or moderate exercise categories.

It’s very easy for us to overestimate our horses’ workload. Keep in mind that modern horses evolved from animals who often traveled 40 to 50 miles per day! They had to really work for their meals, which is not the case for domestic horses. The reason it is important to be honest with yourself about your horse’s activity level is that if you have a horse in the light or moderate category who you unintentionally feed at the heavy or very heavy level, you will likely be at risk for overfeeding, which can have detrimental and debilitating health consequences for your horse.

You may be surprised to learn that some horses who do light to moderate exercise do not require energy in amounts much higher than what is needed for maintenance. On the other hand, some performance horses require up to twice as much energy as a horse at maintenance. It’s all about taking each individual animal’s unique blend of genetics, age and metabolism into account, as well as their exercise intensity and duration. A qualified equine nutritionist can help you determine the winning formula for your horse.

2. Always, always, always start with hay (and a hay test).

Energy can be supplied in the diet by carbohydrates and fat. Carbohydrates fall into two categories: non-structural and structural.

Non-structural carbohydrates (NSCs) come from sugars and starches, primarily from grain concentrates. Most performance horses require some form of NSC, and while there is no reason to fear feeding sugar and starch — sometimes glucose is necessary! — they do tend to be more problematic for our equine friends. As such, it is important to limit the NSCs in the diet to what the horse really needs based on its age and exercise intensity.

Structural carbohydrates, on the other hand, include fiber from forage sources and are one of the most critical components in making sure that the horse’s hindgut functions optimally. Remember: A happy hindgut equals a happy horse.

The large intestine in the horse’s digestive tract is home to billions of beneficial microbes that digest fiber and produce volatile fatty acids (VFAs), which are used as a source of energy. This is the reason why hay alone can meet the energy requirements of some horses. Fiber helps keep the large intestine at the correct pH balance and greatly reduces the risk of colic. After all, forage is what horses were designed to eat and should always be fed at a minimum of 1% of the animal’s body weight per day. The forage component of a horse’s diet also takes pasture grasses into account, so be sure to factor in how much turnout your horse receives.

If you are feeding performance horses, invest in a hay test, which will tell you the exact nutrient levels and help you determine which nutrients need to be added to the diet (based on equine requirements) in the form of grain and horse supplements.

We should also note that good-quality fat is an easy — and, often, safer — way to increase energy in a performance horse’s diet. Fats will be used by the horse’s body during aerobic exercise, which can help save the glucose from NSCs for high-intensity or long-duration exercise. 

3. Remember the importance of water and salts.

While these nutrients are often overlooked, adequate access to fresh, clean water and iodized salt is crucial for all animals, but especially for performance horses.

When exercised in hot, humid weather, horses could lose up to four gallons of sweat per hour! Additionally, horse sweat is hypertonic, meaning that it contains higher levels of electrolytes than what is circulating in the body. Human sweat, in contrast, is hypotonic, meaning that there is a higher concentration of electrolytes circulating in the body than what is in our sweat. This means that giving a sweaty horse plain water will only further dilute the concentration of electrolytes in its body. Given that electrolytes are required to maintain the fluid balance and electrical activity of each cell, they are hugely important for performance!

In normal circumstances when a horse is only emitting small amounts of sweat, an iodized white salt block or loose salt, in addition to hay and grain, will do the trick. If weather and exercise — or some other form of stress, like long-distance travel — lead to prolonged, excessive sweating, providing a high-quality electrolyte supplement with potassium, sodium and chloride is a very good idea.

4. Don’t overdo protein.

Many horse owners accidentally misunderstand how protein should be used in their horses’ diet. As mentioned above, adding energy (or extra calories) to the diet is done with carbohydrates or fat. While protein and, more specifically, levels of certain amino acids are required for growth, muscle and the maintenance of body systems, protein is an inefficient energy source.

Horses have requirements for essential amino acids, the most important of which are lysine, methionine and threonine. This is another reason why investing in a hay test will help you to balance your performance horse’s diet. 

Horses doing light work can often meet their protein requirements (approximately 10% of their diet) from hay and pasture and the use of a ration balancer. Horses doing moderate to heavy work have higher protein requirements, which can typically be met with commercially fortified grain and/or the addition of alfalfa hay.

In general, a protein deficiency is not common in most domestic horse diets; in fact, it is more common for protein to be fed in excess, which will end up as a waste product. If you begin to notice a heavy smell of ammonia in your horse’s stall, this is a telltale sign that you may be overfeeding protein.

5. Help minimize and manage stress.

It’s no secret that performance horses endure stress. What we sometimes forget, however, is that this stress can impact almost every system in an animal’s body, from its digestive system to its musculoskeletal system. A well-rounded approach to managing performance horses includes taking all of these systems into consideration.

• Joint and hoof health: The concussion and force that a performance horse’s limbs must endure is substantial. Providing joint-specific nutrients, like glucosamine and chondroitin sulfate, and hoof nutrients, like organic zinc and biotin, can help protect joints and hooves before damage occurs.
• Antioxidants: Vitamin E and organic selenium are hugely important components in the performance horse’s diet to help combat muscle damage from the free radicals associated with exercise and metabolism.
• Immune function: Organic trace minerals are important constituents of joint and hoof health — not to mention that they help promote normal nervous system function and a healthy immune system.
• Gut health: The stress that performance horses are subject to in the forms of training, travel, new environments and more can absolutely impact their microbiome and cause digestive upset. Additionally, the need for glucose (i.e., NSCs) to power exercise is a reality for many performance horses. Gut nutrients, such as pre- and probiotics, can help minimize digestive distress and maximize safe feedings, travels and training days.

The key to feeding performance horses is moderation. No one ingredient or nutrient is beneficial when there is either a deficiency or an excess. Use common sense, pay attention to your horse’s behavior and cues, and seek balance with an equine nutritionist.

Alltech’s new line of premium equine supplements was formulated to assist with that balance. Lifeforce Elite Performance was designed to be the only horse supplement you’ll need in a performance setting to promote a healthy, whole-body stress response. We are certain that you will get your money’s worth — and your horse will also be able to tell the difference!

No matter the segment of the beef system, stress is a natural and unavoidable hurdle that the beef industry must learn to manage. Ironically, it is often the segmentation of the beef system that results in periods of stress. These stressful times often fall around transition intervals, when cattle move from one phase of production to the next. Weaning and feedlot receiving are two transition periods during which calves will experience multiple stressors. Prolonged exposure to stress has negative impacts on calf performance, and these negative effects can result in long-term issues.

When you consider the long history of the beef sector, stress is a relatively new issue being examined and discussed by those in the industry. In recent years, scientists and producers have begun to realize the impact that stress can have on calf performance. Fortunately, however, there are solutions for mitigating stress for your cattle during transitions. First, it is important to understand what can cause stress, as well as the consequences of that stress.

Stressors that can occur during weaning and receiving include:

• Separation from the dam

The social stress of being removed from the mother can be significant. One management practice that gradually weans calves is fence-line weaning. This technique involves placing weaned calves and dams in adjacent pastures that allow calves to be able see their mothers while being physically separated. Make sure you have sturdy fences with no gaps to prevent calves from crawling through to the other side.

• Transportation

It’s inevitable: At some point, cattle will need to be moved. There are many ways that producers can work to reduce stress during transportation — but similarly to humans travelling to new locations or making a big move, this major transition will likely lead to schedule changes and disruptions, changes in eating patterns, etc.

• Commingling

When groups of cattle are mingled together, they can expose each other to new pathogens. Even if the animals are on the same ranch but are from different pastures, producers need to consider a commingling strategy.

• Unfamiliar diets

Going from their mothers’ milk to feed might feel like a stark transition to some calves. The tips later in this article explain how to get calves to the bunk and help them transition to a new, healthy, nutrient-dense diet.

Stress can have consequences on production, including:

• Impaired growth. Stress causes muscle breakdown and can slow the growth of your cattle.
• Suppression of immune functions, which can lead to a decreased ability to resist infection and an increased susceptibility to getting sick.
• Altered behavior, like reduced feed intake.

A wholistic view of beef production is necessary to identify where leverage points exist within the production system. Recognizing leverage points allows for a more effective application of management practices to minimize stress and improve performance. In beef production, the most effective approach to minimizing stress is a preventative one. Implement practices that will help you foster and maintain a resilient herd. Resilient calves are going to be able to handle the periods of stress that are inherent within the beef system. The key to building resilient calves is implementing proactive management practices.

Outlined below are five easy and practical management tips that will help you produce resilient cattle.

1. Vaccinate prior to shipping.

Work with your veterinarian to establish a vaccination program prior to your animals being commingled and shipped. A vaccination program is essential to building a healthy immune system prior to animals being exposed to novel pathogens in a new place and when surrounded by other animals.

2. Castrate animals as early as possible.

Castration is a stressful but generally necessary management practice. Research has shown that animals experience less stress when they are castrated at a younger age. Some producers will castrate at birth, when they tag or maybe when they take cattle out to grass. Whatever fits into your management schedule, getting your animals castrated early will allow them to recoup before other stressors manifest throughout the following transition stages.

3. Minimize commingling.

Just like with humans, anytime you bring animals from different sources together, you run the risk of exposing them to pathogens. You can reduce this risk of exposure for calves by being strategic about minimizing mixing between sources of cattle. There is also an element of social stress as the newly commingled animals work to establish a pecking order.

4. Expose calves to feed bunks and water troughs.

Familiarize your animals with feed bunks and water troughs prior to shipping. This can help reduce stress during feedlot arrival, as getting calves to feed bunks prior to shipping will help them get onto feed quicker. The sooner they get on feed and start consuming water, the better they will bounce back from transportation stress.

5. Proper nutrition is essential.

When transitioning cattle, it is important to make sure that their nutritional requirements are being met. Meeting the cattle’s protein, energy and trace mineral requirements is essential for their immune function and growth. During periods of stress, it is common for animals to reduce their feed intake. In these cases, providing diets that are more nutrient-dense to compensate for reduced intake is recommended.

It is unrealistic to think that we can eliminate all stress from the production system, but we can minimize the duration and severity of the stress that animals experience. When utilizing these management techniques, consider a schedule that exposes calves to stressors gradually, rather than all at once. When calves feel high levels of stress and no mitigation strategies are used, they can experience critical setbacks. The most important reason to help calves through periods of stress is to set them up for success for the rest of their life — ultimately leaving you with healthy animals, a healthy reputation and a healthy bottom line.

If your pet food company produces balanced diets for puppies and kittens, you know that it is not always easy to differentiate yourselves from the competition.

With numerous options at the neighborhood pet food store and on the increasingly popular e-commerce sites, new pet parents are often bombarded with decisions. Should they go with raw diets for puppies? Dry or wet food for kittens? High-protein diets? Vitamin and mineral supplements?

Ultimately, you want pet consumers to choose your nutrition programs. Let’s look at three ways to make sure that your puppy and kitten diets stand out on the shelf.

1. Beware of the “high-protein” hype.

Yes, puppies and kittens have nutritional requirements that include high protein and calorie levels, but be wary of oversimplifying this message.

Protein sources are not created equal, and claiming that a food is “high protein” is not as important as the levels of essential amino acids that are present in the diets of young kittens and puppies.

Protein requirements for puppies and kittens are really requirements for higher levels of high-quality protein. Do your best to convey to consumers that your pet food brand contains excellent-quality protein from a traceable source that specifically meets the needs of a puppy or kitten.

Furthermore, taking a step backwards, a growing animal’s body also requires nutrients that support its cells’ ability to produce proteins.

Nutrients such as nucleotides, which are the molecules that make up an animal’s genetic material (DNA and RNA), are in high demand throughout the animal’s life, but never more so than during the growth phase, when the gastrointestinal and immune systems are developing quickly.

Nucleotides are found in high levels in the mother’s milk, but young companion animals still have an increased need for nucleotides, even after weaning. Research has shown that nucleotide supplementation in puppies increases their immune systems’ capacity to respond to dangerous diseases, such as parvovirus.

Arming your pet food with the organic molecules and amino acids that really matter for growth and development in puppies and kittens, such as those found in Alltech’s NUCLEO-SACC™, will deliver real results for your consumers and, ultimately, the pets they love.

2. Make it palatable.

This may seem fairly obvious, but reduced food consumption in growing kittens and puppies can lead to major growth and developmental problems.

It is important to communicate to pet owners that while the desired growth rate for both puppies and kittens is “slow and steady” so as to prevent the over-development of their musculoskeletal systems, young animals will grow the quickest in their first 6 months of life and need to be fed in line with those needs.

Building your puppy and kitten diets with highly palatable ingredients, such as glutamic acid, can help promote feed intake in a controlled manner. Additionally, using a body condition scoring system can help to guide nutrition for kittens and puppies. Teaching pet owners how to use body conditioning can help prevent under- or over-development.

For both dogs and cats, body condition is typically assessed on a scale of 1 to 9, with 1 being severely underweight and 9 being obese. An ideal body condition for cats and dogs is between 4 and 5, where their ribs can be easily felt but not seen and a waistline can clearly be identified.

In growing companion animals, body condition is likely to change more rapidly, and there could very well be some “awkward” growing phases. All is well. The important thing is to keep their body condition in mind so that you can adjust their diet as needed before anything gets too out of whack.

Overall, helping consumers understand that growing pets require a balanced diet that meets their increased nutritional demands without overloading their body systems is key. Designing pet food diets that are palatable and therefore encourage consumption means that consumers are less likely to overfeed an imbalanced ration to compensate for what is missing, and that could have a hugely positive downstream effect on their pets’ long-term health.  

3. Focus on functional nutrients.

Functional nutrients are those that may provide health benefits beyond the basic nutritional requirements. Regardless of what type of pet food your company produces, be sure to include functional nutrients that can assist with young companion animals’ proper growth and development.

One functional nutrient that often goes unmentioned is inositol. Inositol is a sugar that is found naturally in the body. Inositol supports proper nerve and muscle function, in addition to optimal cell membrane development. Because of its role in cell structure, it is important for growing animals to have quality sources of inositol in their diets.

Additionally, ensuring that your young companion animal pet food contains 100% organic trace minerals (including copper, zinc, manganese, iron and selenium) will provide a huge boost to your nutrition program. Trace minerals are especially critical during growth to ensure the proper development of all of the animal’s body tissues. Organic trace minerals have been shown to be absorbed and utilized at higher rates in the body than their inorganic counterparts, which means that development and performance can be improved just by feeding your brand’s diet!

Summary

Ultimately, you care about your pet food diets because you care about the puppies and kittens who will be eating them.

Adding sufficient levels of functional nutrients — such as essential amino acids, nucleotides, inositol and glutamic acid — in addition to high-quality essential trace minerals will make your pet food brand the best it can be while also ensuring incredible results for your customers’ new family members.

The pathology of cattle consuming endophyte-infected tall fescue varies greatly based on the weather and the alkaloid concentration. The most readily apparent signs of fescue toxicosis include reduced feed intake, weight gain, milk production and reproductive efficiency, as well as tissue necrosis and a rough hair coat. Decreases in productivity caused by fescue toxicosis are estimated to cost U.S. beef producers more than $2 billion annually (Kallenbach, 2015).

Absorption of alkaloids

Calculating the animal’s retention of ergot alkaloids is difficult due to biotransformation. Generally, it is estimated that 76–92% of consumed ergot alkaloids are absorbed, with the other 8–24% excreted in the feces. The math on alkaloid absorption and excretion doesn’t always add up, as alkaloids are broken down and/or biotransformed into numerous metabolites. Most alkaloids are ultimately excreted in the urine as lysergic acid.

Fescue alkaloids and microbiome shifts

An emerging area of research is the interaction between fescue alkaloids and the microbiome. Decreases in the Erysipelotrichaceae family and increases of Ruminococcaceae, Lachnospiraceae and Clostridiaceae, as well as abundances of Planctomycetes, Chloroflexi and Proteobacteria phyla have been reported for cattle grazing infected fescue. Fescue seed extract, when added to in vitro fermentations, led to increased populations of tryptophan-utilizing bacteria. Considering the tryptophan base of ergot alkaloids, this increase likely indicates an up-regulation in detoxification capacity. The characterization and identification of the three isolates with the highest conversion abilities found that all three were gram-positive, spore-forming rods that produced ammonia from tryptophan, classified as Clostridium sporogenes.

Receptor-binding of fescue ergot alkaloids

Due to the structural similarity of ergot alkaloids and serotonin, dopamine, norepinephrine and epinephrine, several receptor types in numerous tissues are affected during fescue toxicosis in cattle. This results in a wide range of effects on physiology and metabolism. As more research examining the underlying mechanisms is completed, the connections between ergot alkaloid receptor-binding and animal performance grow more complex.

Individual animal sensitivity to infected fescue is affected by:

• Environmental conditions.
• The density of the receptors.
• The capacity for liver and ruminal degradation.
• Other genetic factors.

Fescue's effect on weight gains

Ergot alkaloid-induced vasoconstriction reduces heat dissipation, resulting in a variety of physiological fescue toxicosis symptoms in cattle, including an increased respiration rate and elevated core body temperature. Ultimately, this leads to lower weight gains — which is generally known as the summer slump, as animals spend less time grazing as a result of standing in the shade or water to cool off. In colder months, fescue-associated vasoconstriction combines with thermoregulatory vasoconstriction, resulting in tissue death in the extremities, which is commonly known as fescue foot.

Ergot alkaloid consumption also leads to:

• The thickening of the medial layer of blood vessels
• Endothelial cell damage
• Vascular stasis
• Thrombosis
• Ischemia
• Changes in blood pressure, among other cardiovascular effects

Fescue's effect on rumen fill

The frequency and amplitude of the ruminal contractions, as well as changes in eating patterns due to fescue toxicosis in cattle, combine to affect rumen fill, passage rates and intake.

• Vasoconstriction also reduces blood flow to the rumen, decreasing VFA absorption.
• Increased rumen fill provides a negative feedback loop, exacerbating reduced intakes.
• While the total tract digestibility of the feeds is generally unchanged, these alterations work in concert to reduce nutrient availability, contributing to the reduced growth rate frequently observed in cattle grazing fescue.
• Added to this are the effects of alkaloids on circulating serotonin levels, the hypothalamic center and tryptophan-related satiety.

Fescue's effect on energy metabolism

Ergot alkaloids affect energy metabolism primarily when alkaloid intakes are high and during heat stress. Growth differences in cattle during fescue toxicosis are most likely the result of reduced intake, as no differences in retained energy or energy partitioning were caused by alkaloid ingestion when feed intake was equal.

• When fed near maintenance, cattle had lower basal metabolic rates.
• At higher feeding rates, maintenance energy requirements increased.
• When combined with observed increases in fat loss and a higher capacity for gluconeogenesis in the liver, this indicates the prioritization of energy (when available) toward elevated respiration, thermoregulation and alkaloid detoxification.

Economic losses due to fescue toxicosis

As much as 75% of the economic losses attributed to infected tall fescue pastures are related to decreased calving rates.

For cows:

• Alkaloid consumption reduces the circulating levels of several hormones important for reproductive efficiency, including progesterone and estradiol.
• Changes in ovarian follicle development, oocyte quality and luteal function have been reported.
• When combined with vasoconstriction to the uterus and ovaries, it is no surprise that reductions in reproductive efficiency are seen in cows grazing infected fescue.
• There is speculation that vasoconstriction in the umbilical cord contributes to low birthweights and diminished fetal development.

On the bull side of the equation, research indicates that ergot alkaloids may:

• Affect sperm count.
• Increase the occurrence of abnormal sperm.
• Alter motility, especially during the summer months.

Fescue's effect on milk production and calving

The structural similarity of ergot alkaloids to dopamine results in reduced prolactin secretion from the anterior pituitary gland. Further, changes in gene expression in the mammary glands of cattle consuming fescue indicate alterations in their lipid metabolism and small molecule transport. Altogether, these changes translate to reduced mammary development and lower milk production. Similar changes in lipid metabolism can be seen in reduced levels of circulating cholesterol and the occurrence of fat necrosis (lipomatosis), and in some cases of long-term alkaloid exposure, these fatty masses can cause digestive issues and dystocia. 

Fescue's effect on hair coat and immune function

Reduced prolactin also leads to the rough hair coat that is often observed in cattle grazing infected fescue. Originally thought to be a retained winter hair coat, it is now known that low prolactin levels increase hair growth rates. As prolactin is a co-factor in humoral immune function, the long-term grazing of infected fescue can lead to depressed levels of immunoglobulins. However, as nutritional levels also affect immune function, more work needs to be done to determine whether altered immunocompetence is a direct result of ergot alkaloid consumption or a secondary effect of a diminished nutritional status. While there is no true fescue toxicosis treatment for cattle, there are ways to mitigate the challenges that fescue presents through management, nutrition and feed additives.

Proactive cattlemen are good cattlemen. They have the foresight to combat the inevitable stresses and other challenges their cattle will face. They know that weaning, transportation and other prolonged periods of stress can have a negative impact on immune function and, ultimately, the performance of their animals. So they act to mitigate that stress and, in turn, any health problems their beef cattle are facing. They know that prevention is cheaper than treatment, and they want to see their cattle thrive. Preventative health management practices are key for healthy cattle.

Vaccinations and nutrition have a symbiotic relationship in terms of maintaining healthy immune functions in cattle. While quality nutritional programs are the bedrock of healthy immune function, both nutritional and vaccination programs are important for successful preventative health management on a cattle operation. Preventative health management focuses on promoting an animal’s natural immunity and minimizing the negative growth responses associated with stress and other health challenges.

The role of vaccination

Vaccinating your cattle stimulates their immune systems to produce antibodies that specifically work to combat disease-causing viruses or bacteria. After vaccination, a healthy immune response should translate to a memory of those specific pathogens for the immune system. This memory ensures a rapid response if the animal is exposed to pathogens it has been vaccinated against and allows the animal to avoid infection. Disease challenges vary between different geographies, so it is important to work with your local veterinarian to develop vaccine protocols, as they can identify and walk through the specific needs of your operation.

Although your needs may vary based on your herd and geography, there are a few vaccines that we typically consider crucial for beef cattle, such as a scours vaccine and vaccinating for the bovine respiratory syncytial virus.

Implementing a beef vaccination schedule

While vaccination is generally important, establishing a well-constructed beef cattle vaccination schedule is crucial for vaccine success. One part of that plan — that is, the timing — can make the difference between failure and success. Vaccinations should be timed so that peak levels of antibodies are present when the animal is at the highest risk of infection. Keep in mind that peak levels of antibodies take several weeks to manifest following vaccination, so you’ll want to plan ahead.

The stage of the production cycle will determine the type and timing of the vaccine.

• Pre-calving: A scours vaccination should happen during late gestation so that the highest levels of antibodies are present in the colostrum. A new calf’s immune system is weak, leaving it susceptible to disease and reliant on colostrum to provide it with much-needed antibodies and protection.
• Pre-breeding: For added protection for replacement heifers and cows, it might make sense to implement a pre-breeding vaccination protocol. This should be done around 45 days before you are hoping to breed. 
• Bulls: Keeping your bulls protected may mean implementing an annual vaccination program. Similar to your cows and replacement heifers, these vaccinations may be most effective for bulls around 45 days before breeding.
• Weaned calves: Vaccinations should be given a couple of weeks before weaning so that peak antibody protection is achieved during feedlot arrival. With weaning, transportation, a new environment and mingling with a new group, this time in a calf’s life is the perfect storm for sickness. Vaccination provides calves with some protection as they start this new stage of their lives.

These programs and protocols are only as effective as they are managed. Poor animal health status at vaccination, improper vaccine handling and inadequate nutritional status can all lead to vaccine failure. A failed vaccine costs more than just the amount of product you had in the syringe; it can lead to loss of gain or even death throughout an entire group of calves. Likewise, it is important to understand that vaccines do not guarantee 100% protection and may only provide protection for a period. Even so, can we increase the effectiveness of the vaccine through proper nutrition?

The role of nutrition

Meeting an animal's nutritional requirements is essential for the proper development, maintenance and function of its immune system. Among the other health benefits good nutrition provides, it can also bolster the effectiveness of vaccines and provide longer-lasting protection for cattle. To achieve a nutritional status that supports immune responses, a cattle nutrition program must include energy, protein, trace minerals and vitamins.

• Energy: Immune responses require an abundance of energy. When cattle are exposed to a disease, their immune systems work hard. In terms of the energy hierarchy, an immune response comes before maintenance and production energy. However, shifting energy to the immune response will decrease the nutrients available for growth or maintenance and can cause a reduction in body condition in dams and reduce growth in feedlot animals.
• Protein: Proteins are used to produce antibodies. Since the goal of vaccination is to increase the production of antibodies, a protein deficiency can result in substandard antibody production. As with energy, shifting protein from growth to immune function can negatively impact animal performance.
• Trace minerals and vitamins: The amount of trace minerals and vitamins needed in the diet varies based on the age, role and geography of the cattle, but both vitamins and minerals play an essential role in immune function. Deficiencies in one or more of these nutrients can lead to reduced antibody production.

Nutritional needs at different life stages

Just like with vaccines, the nutritional needs of your cattle will vary based on your specific herd and geography. Factors that can contribute to the nutrition discussion on your operation include the type of facilities your cattle have access to, the feedstuffs used and whether your cattle have experienced health issues in the past. The most important factor, though, is the current life stage of your cattle, as this will dictate the most basic nutritional needs that should be met.

• Newborn calves: As mentioned above, calves are born with a high susceptibility to disease, requiring them to rely on colostrum to acquire those all-important antibodies. Calves should have a healthy gut from the very start so that they can better absorb the nutrients in colostrum and, as they transition to creep feed, maximize their potential for big gains.
• Weaned calves: Maintaining a healthy gut in your calves through weaning is crucial to supporting their gastrointestinal integrity, aiding in vaccine success during the receiving period and keeping them healthy in high-stress situations.
• Cows: The needs of the cows in your herd can vary based on their age and their current stage in the production cycle. Depending on the forage quality, cows may need mineral supplementation for optimum health, immune function and reproductive success.

Herd vaccination programs require an investment of both time and money, and quality nutrition is essential to safeguarding your investment. Talk with your veterinarian about putting together a solid vaccination and nutrition program for your operation. Remember: Proactive cattlemen are good cattlemen, and prevention is cheaper than treatment.

As an involved horse owner, no doubt you have spent time carefully selecting a feed to match your horse’s needs.

We are sure that you have read the purpose statement on the feed tag identifying the grain that will best suit your horse’s stage of life. You have likely even studied the guaranteed analysis to determine the feed’s crude protein, crude fat and crude fiber levels.

However, while this is a great start, there is a bigger story to be told from each bag’s feed tag — one that is more interesting than you may realize.

Understanding what the guaranteed analysis tells you

The guaranteed analysis is an excellent place to start when reading the feed tag because this table is all about what a feed company can guarantee is in their horse feed. This is important for maintaining consistency.

If you think about all the different ingredients in a bag of horse feed, including forage and grain products, the reason why these guarantees are important becomes more obvious. Ingredient prices and fluctuations due to the weather, the season and other variables can easily change the composition of a bag of feed.

Since rapid diet changes are not ideal for equine gut health, feed companies guarantee that certain nutrient levels (typically in a range, with a minimum and a maximum level) will be included in each bag.

The guaranteed analysis also guarantees that the nutrient levels meet the requirements established by the National Research Council and the Association of American Feed Control Officials (AAFCO). For horses, guaranteed analysis requirements include:

• Crude protein
• Crude fiber
• Crude fat
• Acid detergent fiber
• Neutral detergent fiber
• Calcium
• Phosphorus
• Copper
• Zinc
• Selenium
• Vitamin A

The guaranteed analysis on many horse feeds will also include lysine, which is the number-one limiting amino acid for horses. Sugar and dietary starch levels are also required to be guaranteed if a horse feed is marketed with any carbohydrate claims.

While each feed’s guaranteed analysis will differ, many share similar ranges of nutrients to meet a horse’s particular stage of life.

So, if many guaranteed analyses look similar, how does anyone manage to choose the best horse feed? As it turns out, there is quite a bit of information that cannot be found on the tag’s guaranteed analysis alone.

Read the complete ingredient list

The second piece to this puzzle involves reading the entire ingredient list on the feed tag. While this sounds boring — and sometimes daunting! — it can actually be quite eye-opening.

Here are a few things to look for:

• Organic vs. inorganic trace minerals
• Organic vs. inorganic selenium
• Any bonus ingredients, such as added probiotics for horses

Decoding minerals

Minerals are the backbone (literally!) of the horse’s body, making up every organ, tissue and cell. They play a role in every single body system, from skeletal and muscular development to nervous system function and hair and hoof health.

While only present in very small quantities in a bag of feed, they are crucially important for your horse’s overall performance.

Trace minerals make up a very tiny percentage of a horse’s daily intake, which is why their bioavailability is so important. Bioavailability has to do with the rate in which they are absorbed AND utilized in the body.

Organic trace minerals (e.g., zinc, copper, cobalt, manganese) are both absorbed at higher levels and are more readily utilized by the horse because they are presented in a form that mimics the form in which minerals are found in nature.

On the feed tag, organic minerals will be listed as the mineral name, followed by the word “proteinate,” “methionine” or “amino acid complex.”

You can easily spot inorganic minerals because they will be listed as the mineral name followed by the word “oxide” or “sulfate.” For instance, the ingredient “zinc oxide” is an inorganic version, which is both cheaper and less conducive for optimal horse health and performance.

Read the feed tag to check the feed’s trace mineral status. Ideally, choose a feed that contains 100% organic zinc, copper, cobalt and manganese.

The selenium connection 

Selenium is also considered a trace mineral, and in horses, it is especially noteworthy because too much — or too little — can be detrimental and even fatal.

Selenium is a highly important mineral in the antioxidant pathway, which is why it is crucial for recovery, endurance and metabolism.

Inorganic selenium is easy to spot on feed tags and will be listed as “sodium selenite.”

Organic selenium, on the other hand, will be listed as “selenium yeast.”

Be careful: Some feeds use a mix of both types of selenium. Choose feeds that contain only 100% selenium yeast for best results.

Ingredients to support gut health for horses

Your final task in reading the ingredient list on the horse feed tag is to check for any bonuses. Yes, organic minerals should be non-negotiable, but it is possible for your horse to get even more out of its feed! Think of this like the prize at the bottom of the Cracker Jack box.

One example is added probiotics for horses. However, be careful how you interpret these, because not all probiotic supplements, or good gut bacteria, are created equal. You can always call the feed company to clarify how they source and add probiotics into their feeds to ensure their viability and efficacy.

Look on the feed tag for ingredients such as “yeast culture,” “hydrolyzed yeast,” “dried brewer’s yeast” or any specific strain of probiotic bacteria. These ingredients can increase your horse’s ability to fully digest and utilize the feed — thanks to beneficial bacteria — while also potentially saving you from having to purchase additional equine supplements.

A final word

While there is a lot more information that you can glean from a horse feed tag, start by looking for these three pieces of information: trace minerals (zinc, copper, cobalt, manganese), selenium and any added ingredients that support gut health in horses.

The guaranteed analysis is a good start, but it does not tell you anything about the quality or forms in which these very important nutrients are included.

Start reading the feed tag ingredient list, and do not hesitate to call the feed company to ask more specific questions. Nutrition is the basis of every animal’s quality of life. Take it seriously and you will absolutely see a difference in your horse’s health and performance.

Your primary focus as a producer is providing your calves with what they need to grow into healthy adult animals. To do so, gut health is key. Good gut health allows the calf to efficiently utilize the nutrients in the feed, giving them a strong, stable and healthy start.

However, helping a calf meet its true genetic potential is often easier said than done when there’s a battle going on at the microscopic level inside the calf’s gut. Understanding gut health in cows and calves and how to be a more proactive producer regarding your herd’s health will impact the overall efficiency and success of your operation.

Understanding gut health in cows and young calves

“An animal’s gastrointestinal tract is made up of billions of bacteria,” said Dr. Shelby Roberts, a postdoctoral research fellow at the Alltech Center for Animal Nutrigenomics and Applied Animal Nutrition. “This bacterial population is comprised of both some pathogenic bacteria and other bacteria that are beneficial to the animal. In a healthy gut, these bacteria keep each other in balance. Gut health problems start when this balance becomes offset and the bad bacteria start to outnumber the good bacteria.”

For bad bacteria to cause trouble, they must first attach to the gut, where they start to multiply. Antibiotics kill bad bacteria, but they can also kill good bacteria, so taking a different, more proactive approach when addressing calf gut health can be beneficial.

“Maintaining the good gut bacteria, while ridding the system of the bad bugs, is essential to promoting gut health,” Roberts said.

Good gut health benefits cattle in a few ways, including:

• The efficient utilization of feed
• Healthy weight gain
• Immunity
• Gut integrity

Taking a proactive approach to gut health

Traditionally, the gut has been thought of as just another part of the digestive system. However, we also know that it is an active component of the immune system.

Considering the dual function of the gut, one way to achieve optimum gut health in calves is to use a feed supplement created to promote good bacteria and support natural defenses. This preventative approach to animal health can help reduce the number of sick calves and, in turn, decrease the amount of antibiotic treatments as well. This can save producers valuable time and money during the busy calving season.

Over the last 20 years, Alltech has conducted research trials that have evaluated management practices that utilize nutritional technologies and the effects of those technologies on calf health and performance. Certain high-quality prebiotics, for example, have been proven to positively impact calf gut health. Prebiotics are indigestible food ingredients that selectively stimulate the growth and/or activity of one or a limited number of microbes in the gut. 

Establishing strong calf immunity starts with the dam

• At birth, calves are born with a naïve immune system due to maternal antibodies being unable to pass through the placenta, which leaves calves susceptible to disease.
• Colostrum, the first milk produced at calving, is one of the most important components of calf health. Colostrum is a calf’s initial source of the antibodies that are essential for protecting young calves until their immune systems are fully developed, which takes 1 to 2 months.
• Studies of perinatal mortality indicate that 4–12% of calves are born dead or die within 24 hours of birth. Numerous risk factors contribute to higher perinatal mortality rates, including failed antibody transfer from dam to calf, which only reinforces the importance of colostrum and early nutritional management for calves.
• There are numerous factors that can affect colostrum quality, including the dam’s age, breed and nutrition. Making sure that the dam’s nutritional requirements are being met prior to calving allows the dam to pass along quality stored colostrum to the calf.

Better health for improved performance

Producers spend a lot of time and money trying to improve the genetics of their herds. Calves that have both strong immune system development and a healthy gastrointestinal tract will be better able to utilize nutrients efficiently and reach their genetic potential.

“If we can make calves healthier and reduce the energy they spend keeping the bad bacteria in balance, it should result in better performance,” Roberts explained.

The principle of improved gut health for improved performance is best applied during periods of stress, such as weaning and feedlot arrival. These stressful times negatively impact animal health and growth due to exposure to new pathogens and periods of decreased feed intake. Improved performance resulting from increased efficiency can mean more money in the producer’s pocket. This can be achieved through:

• Improved animal growth (average daily gains)
• Reductions in calf treatments and morbidities

Trials have shown that, without a doubt, enhanced calf health and immunity translate to better growth and gains.

“Being proactive with the use of nutritional technologies and establishing a healthy gut could give a producer’s calves the leg up they need to reach their genetic potential,” Roberts said.
