Calving season is gametime for a cow herd, and producers want to make sure that their cows are in peak condition prior to kick-off. The best way to measure the condition of your cow herd is by utilizing body condition scores (BCS). As the name suggests, a BCS is an estimate of a cow’s condition or the amount of fat they are carrying.

The amount of fat — and its placement — determines BCS.

Body condition scoring is an easy and effective tool for producers to use, but a familiarity with the fat deposition and skeletal structure of cattle is required to properly determine BCS. The key areas used to evaluate the degree of body fat on cattle are the ribs, brisket, hooks, pins and tailhead. Typically, for beef cattle, a scale of 1 to 9 is used to indicate BCS, with 1 being emaciated, with all of the cow’s ribs and bones easily visible, and 9 being obese.

• Thin cows have a BCS of 1 to 3
• Moderate-condition cows have a BCS of 4 to 6
• Fat cows have a BCS of 7 to 9

The ideal BCS for mature range beef cows at calving is a score of 5, and for calving heifers, an ideal BCS would be a 6. This difference in BCS at calving is because heifers are still growing and have a higher nutrient requirement for growth compared to mature cows.

Evaluate BCS prior to calving and breeding.

Timing is important when evaluating body condition scores. Producers should aim to evaluate BCS prior to the calving and breeding seasons. Suggested evaluation timepoints include 90 days prior to calving, breeding and the start of the winter season. This will give the producer enough time to try to improve BCS if cows aren’t hitting their target prior to breeding and late gestation.

Body condition scores can be used as a nutritional management tool. For instance, depending on a producer’s facilities, cows can be sorted into groups using BCS. Cows that meet or have above-target BCS scores need no special nutritional intervention and can maintain condition on quality range pasture. Cows with low body condition scores or replacement heifers could be supplemented with additional nutrients to improve or maintain their body condition during calving and breeding.

Another good time to evaluate BCS is heading into winter grazing. Cows that are thin at the start of winter grazing will require supplemental feed just to maintain their body condition, as energy requirements increase up to 40% during the winter. Additionally, trying to improve BCS during the winter is going to cost 20–30% more than during the fall.

 A poor BCS can negatively affect a cow’s calf.

The productivity of a cow herd depends on keeping them within the producer’s ideal BCS. It is well-established that a poor BCS can have detrimental effects on a cow’s reproduction. Thin cows take longer to come into heat and, therefore, only have one chance at rebreeding. Over-conditioned or fat cows can also negatively impact reproduction rates. However, a poor BCS can also affect the overall health and performance of a dam’s calf.

The relationship between cow BCS and calf performance is based on the energy requirements of the cow. To maintain an ideal BCS, cows must have enough energy to support all of their bodily energy requirements. When a cow’s energy requirements are not met by her diet, then she must use the energy stored in her body as fat. The more stored energy she uses, the further she moves down the BCS scale.

There is a priority use for energy for bodily functions, as outlined below:   

Priority energy use by cows (adapted from Short et al., 1990)

1. Basal metabolism
2. Grazing and other physical activities
3. Growth
4. Supporting basic energy reserves
5. Maintaining an existing pregnancy
6. Milk production
7. Adding to energy reserves
8. Estrous cycling and initiating pregnancy
9. Storing excess energy (i.e., fat deposition)

This hierarchy shows that maintaining pregnancy (i.e., gestation), milk production and reproduction are all lower on the list of energy-use priorities. This illustrates the importance of cows consuming enough energy from their diet to meet their maintenance requirements before energy can be used for pregnancy and milk production.

A cow’s BCS affects her reproductive ability, too.

Evaluating BCS at 90 days prior to calving — when cows are about to enter late gestation — is critical, as this is a moment in time that could impact the future growth and performance of her calf. Seventy- five percent of calf growth occurs during the last 60 days of gestation, meaning that the cow’s energy requirements are going to be higher for the last 60 days of her pregnancy. If cows are thin going into the third trimester of pregnancy, then there could be reduced calf growth due to a lack of energy available for supporting the pregnancy.

Smaller calves are more prone to sickness after birth. Weaning weights have also been shown to be lighter when cows have a poor body condition. Until weaning, milk is the major energy and nutrient source for calves. If cows are in poor body condition, they lack the energy necessary to produce the quality milk needed for calf growth.

Research has shown that herds that maintain cows with the ideal BCS ranges (5–7) have better calving and weaning percentages, which are a measure of the herd’s overall reproductive and production efficiency. Thin cows are going to have a harder time maintaining pregnancies and growing calves. A poor BCS leads to fewer pregnancies, fewer calves weaned and calves weaned at a lower weight, which leads to lower overall returns.  

Body condition scoring helps evaluate the nutritional status of the cow herd.

Producers should routinely check the body condition scores of their herds to continually monitor the condition and nutritional status of the cows. If a large portion of the cow herd has a low body condition score, the herd nutrition should be evaluated to make sure that their energy and protein requirements are being met. A prolonged poor BCS can have a harmful impact on production outcomes, which can also negatively impact the economic returns of an operation. Evaluating BCS to determine not only the herd’s reproduction readiness scores but also its nutritional status is an opportunity to positively impact calf performance.

The receiving period can be a stressful time for cattle. Recently, during the Alltech ONE Ideas Conference, Dr. Carlo Sgoifo Rossi gave a presentation titled “Receiving With Ease: Minimizing Stress During the Adaptation Phase.” Dr. Sgoifo Rossi is currently an associate professor in the department of veterinary science and technology for food safety at the State University of Milan. Utilizing his perspective and knowledge of the European beef production system, Dr. Sgoifo Rossi shared some information about the various considerations related to stress and adaptation that producers should keep in mind when implementing feeding programs and management practices.

When cattle are undergoing a transition like weaning and receiving, they experience stressors, including:

• Transportation
• Interactions with other cattle
• Interactions with humans
• Changes in nutrition

These stressors can have a major impact on cattle and can lead to such issues as changes in their immunodeficiency, reduced rumen motility, altered nutrient absorption, increased nutrient requirements and an upsurge of mineral excretion by the kidneys.

Receiving stress can lead to BRD

Regarding immune function, one common but highly concerning issue is bovine respiratory disease (BRD), which can strongly affect the performance of cattle. As illustrated in Figure 1, cattle who arrive and are treated for BRD can exhibit a decrease in average daily gains. It is also important to understand that animals who experience BRD often produce meat with lower marbling and quality grades. Considering all of these factors, mitigating BRD is important not only for the animal’s quality of life but for the producer’s bottom line and the consumer’s satisfaction.

Appropriate sanitary conditions make a difference

While the health of newly arriving animals is impacted by their location of origin, it is also greatly affected by the sanitation and management of the receiving location. According to Dr. Sgoifo Rossi, “The type of vaccination, the type of antibiotics used (and) the type of anti-parasitic product can affect the sanitary conditions of our animals.” Dr. Sgoifo Rossi encouraged producers to approach sanitation with an understanding of their specific herd and facilities and posited that, for some beef production systems, the strategy of going “all-in and all-out with cleaning and disinfection” is the best approach.

Nutrition is critical in the cattle business

When talking about management, we must be sure to properly feed and rehydrate the cattle upon arrival. Ensuring that clean drinking water is readily available and being conscious of the arrival diet are both crucial. Feeding the arrival diets in small amounts multiple times a day is recommended, as this will reduce competition among the animals, giving each of them an opportunity to receive adequate amounts of protein and energy. Arriving cattle can sometimes be considered high risk, making this a critical period for helping them recover properly and get back to normal rumen functionality.

Studies have shown that the appropriate arrival diet should have a crude protein and dry matter composition of less than 13%.

“Several studies show that if we improve the crude protein level of adaptation diets or the energy level of adaptation diets, we increase not only the incidence of morbidity but also the severity of morbidity and, consequently, the risk of mortality,” Dr. Sgoifo Rossi said.

Additionally, with the arrival diet typically being richer in forage and higher in fiber, reducing the chop length of the fiber will also reduce the likelihood that animals will sort through the ration. This is important, because sorting can cause cattle to eat too much starch or protein, which can lead to fluctuations in the pH level.

Consider all of the nutritional needs of arriving cattle

Unsurprisingly, it is also important to consider the nutrients available in the arrival diet. Providing new-arrival animals with the proper nutrients will improve their immunity, digestibility, and energy and protein balances.

To recover rumen and immune system functionality in newly arrived cattle, it is important to consider diets that include the following:

• High levels of digestible fiber
• Yeast
• Mannan oligosaccharides (MOS)
• Slow-release nitrogen
• Vitamins
• Minerals

As mentioned previously, the arrival period is so critical for getting cattle right. Vitamins, minerals and other supplements can help improve their feed and can be fundamental in helping these cattle adapt to their new home. In his presentation, Dr. Sgoifo Rossi mentioned that studies have shown that organic zinc and selenium, live yeast and mannan oligosaccharides can be huge players in the reduction of morbidity and mortality in these potentially high-risk cattle.

Too often, producers and nutritionists underestimate the importance of these ingredients, leading to negative results. Dr. Sgoifo Rossi shared a study completed in Italy that examined the mineral status and mineral plasma levels of cattle after arrival. This trial focused on the evaluation of various mineral levels in the blood immediately after arrival. As shown in Figure 2, 83% of new-arrival beef cattle were in a deficient or sub-deficient condition regarding their copper availability, and 30% displayed deficient or sub-deficient zinc availability and reserves.

Weather can be a stressor

Weather can play a significant role in cattle stress, and more thoughtful management practices should be implemented with the weather in mind. Spring, summer and fall are less of a concern when it comes to sanitation management, but winter is a critical period for sanitation. Producers often forget to consider the relationship between temperature and humidity during the winter and how it can lead to cold stress. This can create a potentially dangerous environment for cattle and can result in increased incidences and more severe cases of BVD. As shown in Figure 3, low-temperature, high-humidity environments can create a risk area where sanitation conditions are an issue, leading to a slower adaptation for arriving animals.

As previously mentioned, there are challenges leading up to and during the receiving period that can result in the highest risks of morbidity and mortality. Implementing the proper sanitation and vaccination protocols, providing sick animals with antibiotics, being proactive about their nutrition, and understanding which management practices to use based on the origin of your cattle, as well as their transportation details and the time of year, are all effective ways to mitigate any potential challenges associated with receiving cattle.

With the changing global climate, many people are becoming more aware of how they impact the environment on a day-to-day basis. And the same goes for horse owners, as more and more equestrians explore sustainable horse farm management practices.

While achieving sustainability in the equine industry may seem daunting, the good news is that there are many avenues for us to explore, and each one makes a difference!

If your horse is boarded at a facility, you may not have control over some common environmental pitfalls, such as manure management or preventing overgrazing of horse pastures. However, almost every horse owner has some say in their horses’ nutrition, and luckily, with a few easy changes, your horses’ diet can become more environmentally friendly.

Trace mineral supplementation in horse feeds

Since they only make up around 2% of a horse’s diet, minerals are often underestimated — but they are actually responsible for hundreds of thousands of functions within the horse’s body, from the development of joint cartilage to maintaining healthy hair and hoof quality.

In the equine digestive system, the bulk of the vitamins and minerals included in the diet are absorbed in the small intestine and taken into the bloodstream to be distributed throughout the body for use.

Macrominerals or major minerals, such as calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur are required in larger amounts than the microminerals or trace minerals, which include copper, zinc, manganese, iron, selenium, cobalt and more. But while the requirements for trace minerals might be smaller, they are majorly important for horse health. 

While hay and pasture grass contain vitamins and minerals in varying levels, depending on the soil quality, processing, region, etc., horses often require additional supplementation for optimal health, which is why grains and other supplements are generally formulated with minerals.

Providing adequate amounts of minerals — but not too much — is best for the environment

Interestingly enough, horses are unable to store large amounts of excess minerals in their bodies, and research has shown that exceeding 100% of their mineral requirements results in higher mineral excretion (i.e., mineral-rich manure), which has important environmental implications.

In her presentation at the Alltech ONE Ideas Conference in June, Dr. Mieke Holder explained what happens when excess minerals are fed to horses. In a brief nutshell:

1. Horses produce about 50 pounds of manure per day.
2. That manure sits outside in pastures or is picked out of stalls but is then left to compost outside.
3. When fecal material gets wet from any type of precipitation, the minerals that have been excreted begin to solubilize.
4. Excess minerals can run off and join surface water or move through soil layers (which is known as “mineral leaching”) and end up joining the underground water supply.

The other piece of the mineral puzzle lies in fecal microbial organisms. Recent research from Dr. Holder’s lab has shown that the bacteria in the feces accumulate some of the minerals that are excreted. Providing minerals in a form that encourages accretion, or “feeding,” by fecal bacteria should continue to be explored, as that appears to decrease the amount of minerals leaching into soil and water.

To bring it all together, Dr. Holder’s research has shown that providing increased levels of trace minerals in horses’ diets also increases the levels of phosphorus that leach from those diets. Given that phosphorus is an element of great environmental concern, it is crucial that minerals are not only fed at the appropriate levels but in bioavailable forms as well.

Organic minerals for horses

Dr. Holder defines organic minerals as minerals that are bound to a ligand carrier, such as a protein or amino acid chelating agent. Several examples of organic trace minerals are those offered by Alltech as Bioplex® (copper, zinc, manganese, cobalt and iron) and Sel-Plex® (organic selenium). In contrast, inorganic minerals are complexed with a compound, such as a carbonate, chloride, sulfate or oxide.

While research over the years has shown varied results in terms of the differences between organic and inorganic minerals in horses’ diets, several compelling studies have shown that organic minerals are absorbed at higher levels and are more readily usable by the horse’s body than their inorganic counterparts. When organic minerals are absorbed at higher levels, that also means that fewer minerals are excreted, which can help protect the environment.

For example, glutathione peroxidase, a selenium-dependent antioxidant enzyme, showed increased activity after exercise in horses fed Sel-Plex® versus horses who received inorganic selenium (in the form of sodium selenite).

Other recent research has shown that supplementation with organic trace minerals can help improve joint cartilage indicators and antioxidant activity in growing horses.

Given that we want our horses to be around for many more years than the typical production animal, the fact that there is evidence indicating that organic trace mineral supplementation can help maintain horses’ health, development and performance is notable.

Minerals as an equine management tool

Thanks to Dr. Holder’s presentation, we know for sure that:

• Horses have mineral requirements that are often unmet by forage alone. Trace minerals, despite only being required in small amounts, have great value in preventing health problems.
• Feeding excess minerals to horses is not only financially wasteful but also has a negative impact on the environment.
• Prioritizing high-quality mineral nutrition for our animals may not be the most common or well-known route for minimizing our environmental impact, but it could make a huge difference.
• As a horse owner, you can read your horses’ feed and supplements labels to learn whether the trace minerals included are offered in an organic form, which can be identified by names that often include the words “proteinate,” “chelate,” “amino acid complex” or “methionine.”
• Seek to feed the best-quality nutrition, not only for your horses’ health and performance but to help mitigate any environmental hazards as well.

I want to learn more about nutrition for my horses.

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!

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.

For any cow-calf operation, a primary goal is to enhance the ratio of pounds of calf weaned per cow bred annually. A critical component of reaching this goal is keeping the herd as close to a 365-day calving cycle as possible. To this end, shortening the postpartum anestrus interval and increasing first-service conception rates to reduce the need for cattle rebreeding are key topics of discussion and research within the industry. Both nutrition and body condition affect anestrus and conception, dictating the cows’ ability to rebreed successfully.

Identifying and correcting problem cows between calving and breeding is not an easy proposition. As such, the best option is to set a cow up for success before calving by ensuring that her BCS is between 5.5 and 6 and that her nutritional needs are met.

Return to estrus

The length of the postpartum anestrus is fundamental to determining the calving interval. Given a typical 283-day cow gestation period, cows must have a postpartum interval of 82 days to produce one calf every 12 months. Cows cycle from anywhere between 30 to 100 days after calving, with nutrition and cow age contributing to the anestrus length. In beef cows, the uterus returns to its non-pregnant size by around 30 days post-calving. Before cows are ready to cycle normally, an additional 10 days is required to complete the uterine involution.

Beef cows that calve early in the season and cycle early have better chances of fully completing their uterine involution and returning to their normal cyclicity before the start of the breeding season. Cows that are cycling before starting the breeding season are most likely to conceive on first breeding — and within the first 21 days of the breeding season.

Research has also shown that the nutritional requirements for beef cattle in late gestation affect the cow’s health and return to normal cyclicity. The importance of body condition scores and nutrition in relation to conception and pregnancy rates has been thoroughly studied, with results indicating that:

• Cows need access to sufficient protein and energy to calve with a BCS between 5.5 and 6. Not only is being in the proper condition important for allowing the cow to produce high-quality colostrum, but this BCS must then be maintained throughout the breeding season.
• Underconditioned cows are slower to cycle, skewing the 365-day calving cycle, and cows that lose condition between calving and breeding are significantly less likely to conceive.
• Immediately following calving, the cow is using the nutrition she is provided with to recover from the stresses of the gestation period and calving, as well as to produce milk for her new calf. Only after those needs are met will the cow redirect her energy and nutrients toward preparing for the next breeding season.

A significant body of external work supports the use of fat supplementation to enhance reproduction, generally in relation to managing cattle BSC and/or avoiding a negative energy balance in transition animals. In these cases, oleic acid (C18:1) may be the preferred fat source, as it boosts energy being partitioned toward the cow’s body reserves. 

Alternatively, stearic acid (C18:0) is preferentially used as an energy source, and dietary supplementation may reduce the cow’s reliance on mobilizing her body reserves. All fat feeding should be carefully considered — especially the type of fat and the timing of the feeding, as there are instances in which supplemental fat has reduced reproductive efficiency by increasing anestrous, reducing intake and, in turn, the energy balance, or inhibiting prostaglandin synthesis.  

Conception success and embryo mortality

A lot of attention is given to conception rates in beef cattle. However, research from Ft. Keogh in Montana indicates that 90–100% of cows will conceive at first breeding and that it is actually early embryo mortality that gives rise to many open cows. 

• Approximately 25% of cows suffer embryonic loss before the 28th day of their gestation period, with a further 8% of pregnancies lost before day 42. 
• Unlike late-term pregnancy losses, early embryo mortality is often not noticed on the farm. These losses are often miscategorized as cows that didn’t catch on the first round of breeding.
• Embryo mortality is estimated to cost U.S. cattle producers $1.4 billion annually as a result of open cows, lost productive days and rebreeding costs. 
• Embryo survival is affected by a variety of factors, including maternal and fetal nutrition, genetics, maternal stress, parity and health. As a result, research examining this issue is limited, and often, no clear answer for reducing embryonic loss is determined.  

How nutrition affects reproductive success

Balancing energy and protein in cow diets is important, as lower conception rates are often observed in cows with very high dietary protein intakes. Excess protein can increase the urea concentration in uterine secretions, which results in elevated prostaglandin levels. As prostaglandin is a signal for the body to return to cyclicity, this mechanism may be partly responsible for early embryonic losses in some herds.

As with body condition maintenance, research indicates that fat supplementation may additionally have a direct impact on reproduction.

• Dietary fat has been reported to increase follicle formation in super-ovulated cows, possibly by increasing the serum insulin levels as a mediating step. 
• Luteinizing hormone (LH) secretion, which triggers ovulation and CL development, is controlled in part by an animal’s energy status; thus, fat supplementation that enhances the energy balance will also aid in LH regulation.
• Dietary fat supplementation has also been reported to increase serum progesterone. A poor-quality CL or insufficient progesterone can both be responsible for pregnancy losses before implantation, particularly in cows that are bred on their first cycle after calving. This once again highlights the importance of early calving to provide cows sufficient time to complete their anestrus and return to normal cyclicity before the start of the breeding season.

Beyond energy and protein, trace minerals — such as copper, zinc, manganese and selenium — play key roles in health, metabolism and the general nutritional requirements of beef cattle. Sub-clinical deficiencies in trace minerals can lead to reduced cyclicity and diminished reproductive health. Minerals impact colostrum quality and calf immunity, but their value for the cow should also not be forgotten. 

Optimizing trace minerals can aid in maintaining optimal uterine health by reducing the risk of:

• Metritis.
• Retained placentas.
• Other adverse events that lengthen the time needed for uterine involution and a return to normal cyclicity.

Nutrigenomics research has also shown that minerals affect several metabolic pathways related to the preparation of the endometrium for implantation.

Other factors affecting success

The period before the start of the calving season is a good time to go over your herd health plan. Connect with your veterinarian and other experts to ensure that your management and vaccination programs are in line with the best practices for your region.

This is also a good time to make sure that your recordkeeping is up to date. Diagnosing breeding and reproductive issues is often an exercise in looking back. Working from accurate records can make the difference in identifying the underlying causes and developing a plan to prevent them next year.

The bottom line

Beyond the importance of individual nutrients, timing the supplemental feeding of cows correctly is important. The last 50 to 60 days of the cow’s gestation period are well-known to be critical for colostrum quality, as well as calf health and growth — but preparation for calving and rebreeding go hand in hand. As it takes time for nutrients to be absorbed, metabolized and take effect in the animal, a feeding program to support reproductive soundness and breeding-related stresses should begin before calving and continue through the confirmation of pregnancy.

A few key indicators to monitor are the percentages of mature cows calving during the first 21 days of the calving season and of late-season-calving cows. If either of these metrics run above average, it is time to take a close look at your calving and breeding season program.

Simply put, cows need to be set up for successful rebreeding before calving. Waiting to think about the breeding season until after the calf hits the ground is too late to affect major change in your cow herd’s performance.

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.

Are you looking to improve the efficiency of your cattle? Studies have shown that organic trace minerals outperform inorganic minerals when it comes to cows and their calves. Dr. Anne Koontz, Alltech research scientist, discusses the benefits that organic trace mineral supplements can provide to the calf immune system and average daily gains, as well as how they affect cow fertility and reproductive efficiency in cattle.

The following is an edited transcript of Kara Keeton’s interview with Dr. Anne Koontz. Click below to hear the full audio.

Kara:              I'm joined today by Alltech research scientist Dr. Anne Koontz to discuss organic trace minerals in beef cattle. Thank you for joining me today.

Anne:             Thank you for having me.

Kara:              Anne, trace minerals: are they that secret weapon in our feed that everyone knows exist but we don’t fully understand what they do?

Anne:             I think we've always known the importance of trace minerals, but what we're really seeing, with new research that's coming out, is we're diving into things that we didn’t know they were doing for us, and we're seeing some benefits and really putting data to those benefits and understanding them a bit better.

Kara:              So, when you're talking about the benefits, what are the minerals specifically that we're talking about? And tell me about some of the benefits that they're providing to our animals.

Anne:             Right. When we're talking trace minerals, we're really talking about things like zinc, copper, cobalt, selenium — those minerals that are in very small amounts in our feeds. They get a little bit overlooked. We all toss them in, but really understanding the levels and the forms that are important is something new.

                        What we see with trace minerals is we've always known that you have to have them there at a certain level, and especially in beef cattle. We've gone, "Well, there are trace minerals in the grass, so I'm not going to worry about it too much," but there are a lot of surveys that are showing that trace minerals in the grass are actually at levels that aren't sufficient to really promote the benefits we know that trace minerals (provide that) are important for us — so immunity, health, metabolism and reproduction, which is really what I focused on recently.

                        When it comes to reproduction, we know that low amounts of trace minerals in the diets of our cattle can cause problems in both the bulls as well as the cows. When we're talking about cows, we're seeing issues like lower fertility. Pregnancy maintenance rates aren't as good; we get good conception rates, but it's that maintenance of pregnancy that we're finding, if we focus on the minerals, we actually get better pregnancy maintenance.

Kara:              So, you're saying that, when you're looking at different animals in the sense of calves versus mama cows versus your bulls, you really have to take that into consideration when you're looking at applying trace minerals to the feed.

Anne:             Absolutely. All of your animals are going to need trace minerals, but the levels and the amounts that they need are going to vary depending on their life stage — and especially when you're talking about your cows. They're going to need different levels of minerals when they're pregnant than when they're lactating and than when they're dry and waiting for that next calf to come to the ground. Their mineral needs fluctuate, and we need to take that into account, but always be aware that they do need minerals pretty much all the time.

Kara:              How do Alltech's organic trace minerals, Bioplex and Sel-Plex, hold up in the gut in regard to stability, and how are they used in the different animals like you're talking about — different stages of life or production?

Anne:             This is another one of those areas that's sort of cutting-edge, and we're really starting to see some new things coming out here, and the stability area is really interesting. What we're finding is that, both in premix situations as well as in the gut of the animals, organic minerals hold their form and shape far better than inorganic minerals. Inorganic minerals are bound to, generally, some sort of an ion, and once they hit the gut, they break apart from that ion, and then they have the ability to bind other things. They can bind up important parts of your diet or other minerals so they're no longer available to the animal, and so the nutrition ultimately becomes less in that diet.

                        With the organic minerals, they don’t break apart and rebind and that sort of thing, and so, they're more stable and they're more available. When we really look at the availability as far as the bioavailability, what we find is that organic minerals can be as much as 130–200% more available than a sulfate form, and even more than that, from an oxide form of a mineral. So, we're able to use organic minerals at lower levels in the diet but get the same benefits, or use them at the same level and get higher benefits when we might be addressing a subclinical deficiency where we didn’t realize we had a deficiency because we didn’t see any outward effects of it, but the animal has the ability to respond to that slightly more available or slightly higher level of mineral in the diet.

Kara:              So how is this used on the farm, and how are farmers embracing this transition, possibly, from using inorganic — which I know has been used for years — to the organic minerals and more natural solutions in their production?

Anne:             The feedback from farmers has been incredibly positive, and it mirrors what we've seen in research. We've had research on this from the early '90s in bits and pieces, where we did larger-scale research looking at other issues but we just happened to collect a little bit of reproductive data on the side.

                        Starting about a year and a half ago, I started pulling out those bits and pieces of reproductive data and putting them all together in a response to a question we had from our sales team. What we found is that we could do this consistently through all these bits and pieces of trials over the last 30 years. Then, when we took those bits and pieces and said, “This is what we've been able to do with reproduction as far as increasing calving rates, increasing pregnancy maintenance and, ultimately, affecting calf production from the cows that were fed those organic trace minerals with higher weaning rates and higher feed liveweight gains,” that was quite exciting to our sales team and to our customers.

                        When we took it out into the field to the customers, the customers were reporting back exactly the same things we saw in university research trials. They're reporting back higher pregnancy rates, higher conception rates to AI (artificial insemination). They're reporting back that their heifers are reaching puberty earlier, so they're ultimately calving earlier in their life span. So, we're shortening the non-productive time of these animals on the farm, and that's very exciting for us, and it's very exciting for the consumers, because anytime the animal is not productive — if they're slow to cycle back during the breeding season and slow to get pregnant again, or if your heifers aren't reaching maturity until later in their life — you're feeding an animal that's not ultimately bringing you back any money on the farm. So, if we can shorten that time period that we're feeding unproductive animals, we're saving farmers money. We're ultimately getting closer to that beef production gold standard of one calf per cow per year.

Kara:              So, saving money, healthier cattle — these are all things farmers are looking for when they're looking at feed, when they're looking at production. What are some other things that you believe, as you continue your research, (you) are going to find in using trace minerals? And not just using — we've always used trace minerals, but using the organic trace minerals, and as you learn more about them — are there other things on the horizon that you're excited about or you think you're going to see?

Anne:             There are some things I'm particularly excited (about) and am hoping to start looking at a bit more deeply. One of the things that keeps coming back to us is that, within the beef industry, as I said before, we don’t have an issue with conception rates. Our cattle are incredibly fertile. We get 95% or greater conception rates. What we do see as an issue is early pregnancy loss. There's some data out of Fort Keogh with Dr. Gary in Montana that says 25% of those cattle that conceive lose pregnancy before 28 days. So, it's that very first bit, where we didn’t maybe quite realize they were pregnant, so we thought maybe they didn’t conceive — but what he's saying is, it's not the conception; it's that early pregnancy loss in the first 28 days.

                        So, what some of the research we have at Alltech has shown is that we're getting better pregnancy rates from AI in beef cattle, and we're getting fewer services per conception in dairy cattle, which is the same way of looking at something, but looking at it from a different angle. So, what I firmly believe is that those two numbers are showing us that we're getting better maintenance of pregnancy during that first 28 days, so I'd really like to get a chance to dive deeper into that and really specifically look at that in some of our research.

                        The other thing that's particularly interesting to me going forward is taking this to some of our purebred and AI systems and looking at embryo, flushing an embryo quality on that side of the beef industry. We've got some very preliminary data there from the field, where people have used this, that shows we're getting better embryo quality, more transferable embryos and things like that out of these embryo-flushing situations, so I'd like to dive a bit deeper into that and see what we can do on that side as well.

Kara:              That's exciting. I know that your area of specialty is with beef cattle. Do you work with dairy cattle as well?

Anne:             I do. I actually work with pretty much any species.

Kara:              Okay. Well, that's what I was going to ask. What you're learning from beef cattle, and utilizing organic trace minerals in beef cattle — are you also doing research or are there researchers at Alltech looking at this in other livestock?

Anne:             There absolutely are. A lot of the research that I was able to find when I started looking into this, and seeing what we already had in our databases, came from the dairy industry, and so, we've seen this consistently in the dairy industry. We can see this consistently in the beef industry. There are some indications that we see something very similar in the swine industry. Poultry is a little bit funny because eggs are a bit different than a pregnancy, but on the pig industry, what we're really seeing is that we're getting heavier birth weights, we're getting more pigs per litter, and those pigs are thriving more after birth when the sows are fed Bioplex minerals.

Kara:              Trace minerals (are) maybe not a secret weapon, per se, since we've always used them, but maybe it's the organic and natural direction that is something that's going to make a difference to producers down the road.

Anne:             I think that's accurate.

Kara:              Okay. Well, thank you so much for joining me today, Anne.

Anne:             Thank you for having me. It's been a pleasure.

Kara:              This was Dr. Anne Koontz, Alltech research scientist.

Have a question or comment?

African swine fever (ASF) is a highly contagious and deadly disease that affects domestic and wild pigs regardless of age and sex. ASF cannot be spread to humans and other non-swine animals and livestock and is not a threat to human health. However, humans can carry the virus on their clothing, shoes and equipment and can spread the disease unknowingly.

Historically endemic to African countries, ASF has been spreading rapidly throughout Asia and parts of Europe through 2018 and 2019. What are the symptoms of ASF, what can we do to prevent the disease, and are there any treatment options?

Signs and symptoms of ASF

• High fever (40.5–42oC)
• Sudden loss of appetite
• Hemorrhages on skin and internal organs, particularly lymph nodes
• Diarrhea, vomiting (sometimes with bloody discharge)
• Abortion
• Depression
• Coughing
• Difficulty breathing
• Sudden death
• High death loss

While these symptoms are similar to classical swine fever (CSF), ASF is caused by a unique virus that is distinct from CSF. Unusually high mortality rates among pigs of all ages can be a strong indicator of ASF. However, the only way to know for sure which virus pigs might be infected with is through laboratory testing. If you notice any of the symptoms mentioned above in your herd, contact a vet as soon as you can to ensure that the correct quarantine and treatment are completed. This could help limit the damage on your farm.

Tips to prevent ASF from entering your farm

It is possible to keep ASF out of the farm, even in countries where ASF is endemic. Here are nine prevention measures you can take to avoid ASF.

​

1. Implementation of strict importation measures for animal products:

Ensure that neither infected live pigs nor pork products are introduced into areas free of ASF. ASF-positive countries can have their animal exportations restricted or prohibited as a result of the detection of infected meat. Check infected regions before importing products that could potentially be contaminated.

2. Proper disposal of all food waste from aircrafts or ships coming from infected countries.

Furthermore, no human food waste should be fed to pigs.

3. Efficient sterilization and disposal of garbage: Avoid swill feeding (i.e., garbage feeding).

Feeding of catering waste is a high-risk practice; if the food waste is contaminated with ASF, it can infect a healthy herd. Do not expose food waste that wild swine species could access. Carcasses, discarded parts from slaughtered pigs and food waste should be disposed of appropriately. 

4. Rapid slaughtering of all pigs, infected or not (stamping out):

Recovered or surviving animals are virus carriers for life. Therefore, to avoid spreading the disease to other pigs and to prevent relapse, it is safer to slaughter both infected and potentially infected pigs. Stamping out tends to be a short-term method to eradicate the disease. Nevertheless, it is generally the most cost-effective method that allows farms to be free from ASF in the shortest time.

5. Strict on-farm biosecurity:

Keep viruses and bacteria out by complying with biosecurity rules, including proper disinfection of clothing and boots, as well as not bringing pork products that have not been properly heat-treated onto a farm. Farms should maintain dedicated footwear and clothing that stay on the farm.

6. Controlled animal and human movements:

Pigs should be sourced from trusted and certified suppliers. Vehicles, equipment and people are also fomites of ASF. Ensure that anyone who enters the farm has not been in contact with any other pigs over the past 48 hours. Farm visitors who have been in countries that are ASF-positive need at least five days of downtime before entering the farm. Vehicles and equipment should be properly cleaned and disinfected before entering the premises. As secretions and excretions from sick or dead animals are a source of ASF, carcass-hauling trucks are high-risk and should not enter the farm.

7. Disease surveillance and monitoring:

This is especially important when transporting live pigs and pork products. In addition, pig farms should maintain a strict health monitoring program. All sick or dead pigs should be inspected and examined for ASF. To detect ASF early, pigs slaughtered for own-home consumption should be inspected by an official veterinarian. Regarding staff training, holding regular prevention lectures and strengthening quality assessments as well as the daily records of feed ingredients is advised.

8. Efficient and early detection of the virus through laboratory tests:

Notify a vet immediately upon spotting signs of ASF, and get the pigs tested.

9. Strict quarantine protocol:

Strict quarantine measures should be applied in both ASF-free zones and infected zones to prevent the entry of the disease and/or to keep ASF from spreading further.

Treatments for ASF

• Currently, there are no treatments or vaccinations available for this animal disease.
• Preventative and cautionary measures can be taken to protect animal health.
• Contact between sick and healthy animals can transmit ASF. Therefore, infected animals must be isolated and culled immediately upon confirmation of ASF.

Did you know?

• North America and the Oceania region remain the only areas that have never had reported cases of ASF.
• ASF poses no risk to human health. Humans cannot get infected by ASF.
• ASF infects domestic and wild pigs, as well as a variety of soft-bodied ticks.
• Wild boars and warthogs can be carriers of ASF. Make sure they don’t come in contact with domestic pigs.
• Frozen meat from infected pigs can harbor the virus for up to six months.
• The ASF virus has been estimated to survive for up to 15 days in feces and five days in urine at 21°C.
• It takes 30 minutes of cooking at 70oC to deactivate ASF in meat products and 30 minutes at 60°C for serum and body fluids.
• Curing or smoking pork products does not destroy the virus.
• ASF can be transferred via feed (Niederwerder, et al., 2019). It is important to work with trusted suppliers and vendors to verify ingredient sources and determine what their biosecurity and quality programs entail.

The importance of feed safety and a favorable health status

Studies have shown that feed can be a carrier of certain harmful pathogens (Dee, et al., 2018). As an added layer of protection, put safeguards in place and utilize feed intervention technologies, such as acidifiers, to support the integrity and quality of your feed.

Acidifiers are known to have beneficial properties that “control bacterial growth in feed, […] inhibiting growth of pathogenic microbes” (Jacela, et al., 2009).

Products such as Guardicate™* have been shown to be effective for promoting feed safety and can be used as an important component of your farm’s greater biosecurity program. Over almost four years of research, Guardicate has shown its effectiveness as an acidifier, as it addresses feed quality concerns by helping maintain a favorable feed environment.

Together with other solutions, like Sel-Plex®, Bioplex® and Actigen®, Alltech’s nutritional technologies provide peace of mind that you are safe from the risks that could negatively impact your production while promoting a positive health status for your animals.

Improper mineral supply can have major consequences for the health and productivity of your herd. Improved mineral status has been shown to have a positive effect on immune function. The Alltech Mineral Management program focuses on feeding organic minerals such as Sel-Plex and Bioplex, which are better absorbed and utilized by the animal and, thus, can meet their nutrient needs for optimal health.

Gut health and the microbiome also play a key role in maintaining the overall health status of the pig. Actigen is able to support immune function, gut microbial health and gut function and development, promoting overall animal health and performance.

*Guardicate is only available in select countries.
