History shows that production profitability is closely tied to several key factors, one being cost of gain. Producers can use their records on specific input costs and gain calculations to benchmark their enterprises. Simply, cost of gain can be used to make good business decisions.

Management records indicate that feed costs can account for 50-70% of the cost of producing beef, and should include both purchased and raised feed. The cost of raised feed is computed using the opportunity cost of feed grains, hay, pasture lands and other feedstuffs produced by the ranch and utilized in the cattle growing operation.

Feed per unit of gain (feed efficiency) has remained a very important factor in producing profits or losses. Feed conversion or efficacy is typically assumed to be an indirect indicator of profitability. The calculation for feed efficiency is: total feed consumed ÷ (weight sold – weight started). Therefore, as the name implies, it is a simple ratio of feed divided by amount of gain or a ratio of average daily intake divided by the average daily gain. Feed efficiency is usually a fairly straight forward number to generate.

The next step is to link economics to biology. By using the feed cost instead of feed consumed, making an expression of feed costs per unit of gain, one has converted a biological equation to an economic indicator.

Total cost of gain can be divided into the compartments that make up the gain. For example, researchers and nutritionists agree that Amaferm^® will increase average daily gains of stocker cattle about 0.2 pounds per day. This weight gain is in addition to the 0.2 pounds per day that will be realized from the mineral, trace mineral and vitamin supplementation in the Gain Smart^™ minerals. With a total supplementation cost of about 12¢ per head, per day, the cost of gain for Gain Smart mineral is only 30¢ per pound. Cattlemen will always be drawn to supplements that efficiently enhance gains, lower the overall cost of gain and improve profits.

It is a widely known and accepted fact that supplementation is a large portion of cash costs for every cattle operation. Protein is a crucial nutrient in a beef cattle diet (or any species for that matter). Unfortunately, protein supplementation is frequently a high-cost item in the nutritional program, and therefore, often ignored.

Protein is essential within the diet of a ruminant to supply the ammonia needed for microbial growth and provide the amino acids needed for absorption from the small intestine. A deficiency in protein can limit microbial activity, microbial protein synthesis and rate of digestion. All of these can impact feed and energy intake. Furthermore, if an animal receives insufficient amounts of protein, production of meat, milk and wool can be dramatically reduced.

However, when a producer is supplying supplemental protein to their livestock, they don’t always think about how much of that protein the animal is actually utilizing. Regardless of the nutrient, there is a portion that can and can’t be utilized by the animal. The component that is available to be utilized by the animal is considered “digestible”. On average, only about 40% of supplemental protein can actually be digested by the animal and used for growth, reproduction, lactation, etc.

So how can we make digestibility of protein more efficient? By increasing production of microbial cell protein (MCP). Microbial cell protein is the purest form of protein (up to 80% digestible) and is derived from bacteria present in the digestive system. Amaferm^®, found in EVERY BioZyme product, has been shown to result in an average increase in MCP of 34%, which correlates to more performance and ultimately more profit in your pocket.

In addition to the use of Amaferm, here are a few extra tips to proper, economical protein supplementation.

1. Identify your animal’s requirements.

In order to develop a cost effective supplementation program, you must first know the protein and energy requirements of your animals. Requirements for protein vary throughout the year and are dependent on the animal’s stage of production. For example, growing calves and cows in early lactation have some of the highest protein requirements. From weaning to puberty, cattle experience the largest increase in protein deposition throughout their lifetime. In turn, their requirement for dietary protein is particularly high as well. In regards to a cow that has just calved, her requirements are highest the first two months post calving due to the increase in protein demanded for lactation; while her lowest requirements are seen post-weaning. A cow’s protein requirement will begin to gradually increase again as fetal development increases.

2. Identify what is in your feed.

The second step in creating a successful supplementation program is knowing the protein content of your total diet. Protein can come from pasture, stored forages and supplemental feeds such as grain. BioZyme provides lab testing and ration balancing services free of charge to its customers. By understanding the nutrient profile of your available feedstuffs, you can better identify what supplements you can add to your feeding program to meet nutrient requirements and optimize animal performance without over or under feeding.

3. Identify which product best fits your management situation.

Generally, protein supplementation is needed in the late summer when forage quality is at its lowest and when grazing crop residues in late winter. For fall calving herds, forage protein is usually limited during early lactation. BioZyme offers a variety of high-quality protein supplements to meet a producer’s supplemental protein needs. The Concept•Aid^® POWER Products all contain 20%, all-natural CP and provide enough vitamins and minerals to serve as a replacement for loose mineral supplements. VitaFerm^® offers its POWER protein supplements in tub, meal and block form to fit differing management scenarios, allowing for maximum convenience along with improved animal performance. As a more economical alternative, the VitaFerm 30-13% Protein Tub offers a higher protein level in a smaller feeding rate, as well as a complete mineral package in every feeding.

Proper protein supplementation at various stages of production can prove extremely beneficial to overall animal productivity. The Amaferm advantage present in VitaFerm products increases the rate of digestion, allowing animals to meet their nutrient requirements faster and on less feed. Increased forage digestion provides for greater microbial growth and production of microbial protein to provide the animal with more protein for growth, lactation and reproduction.

Many producers are currently in the midst of weaning madness. There is a plethora of information on weaning management techniques, vaccination protocols and feeding recommendations. Regardless of your operation’s weaning procedures, the most important considerations should be keeping calves healthy, on feed and gaining weight. Ensuring a seamless transition from a milk-based diet to dry feed and hay starts with proper nutrition to maximize performance potential and prevent sickness.

Prior to weaning, a calf’s diet consists of milk that is energy rich and packed with protein, vitamins and minerals. Therefore, when a calf is weaned those nutrients a calf received from milk must be replaced with high quality forages and additional supplementation. Whether you are turning calves out on grass or leaving them in a dry lot, here are some important factors to consider:

Weaning on grass: It is important to consider the quality of the forage if turning calves out on grass post weaning. During this time of year, many forages are in a declining state of nutrient content. As a result, supplemental feed may be required for calves to achieve desired
weight gains.

Weaning in a dry lot: Calves weaned in a dry lot must learn to eat from a bunk if they have not been exposed to them prior to weaning. It is important to consider bunk space (at least 12 inches per calf) and bunk height so that smaller calves can reach feed and water.

Weaning stress coincides with a time in a calf’s life when its trace mineral status is at its lowest. A calf is born with elevated levels of trace minerals (copper, zinc and selenium) acquired in utero. Unfortunately, weaning often depletes these mineral stores. This, combined with the additional protein and energy needed to accommodate the rapid growth of calves during this stage of production, means proper nutrition is crucial. BioZyme^® offers a wide variety of products to meet your operation’s nutritional needs during weaning. Here are some of the products producers have had success implementing within their weaning nutrition programs:

Vita Charge^® Stress Tub: A 50 or 200 lb. cooked molasses tub that contains Amaferm^® and MOS to support digestive health and promote feed and water intake during times of stress and/or recovery from sickness. MOS traps bad bacteria limiting their ability to do harm to the animal. The Stress Tub conveniently allows beef cattle to get their daily dose of organic trace minerals, vitamins and B vitamins without additional handling.

VitaFerm^® Sure Start^® Pellet: A highly palatable, pelleted vitamin and mineral supplement for beef cattle formulated with a high concentration of vitamins and minerals to alleviate the negative effects of stress. This product contains high levels of vitamin E, niacin and thiamine, as well as organic zinc, cooper and manganese, and a double dose of the Amaferm^® advantage. It encourages calves to come to the bunk and provides a smooth transition during the most stressful time in a calf’s life.

Gain Smart POWER 37: A pelleted, 37% natural protein, vitamin and mineral supplement that provides a cost-effective way to promote gain and general herd health. Contains a nutrient package specifically designed to balance high grain diets and supplemental protein, as well as organic copper and zinc plus added iodine for maximum bioavailability to the animal to support hoof health and immunity.

Sure Champ^®: A pelleted vitamin and mineral supplement that can be top-dressed or mixed in a ration to improve digestive health, stimulate appetite and optimize health. Typically used in show cattle, Sure Champ is a versatile product that contains 25% protein and elevated levels of highly bioavailable vitamins and minerals to achieve maximum performance potential. Sure Champ contains organic zinc, copper and manganese and the maximum allowable level of selenium. Added vitamins of A, D and E, niacin, and B-12 allow for added growth, bloom and overall health.

Implementing any of these products will take your nutrition program to the next level and ensure continued weight gain and improved immune response of newly weaned calves. For more information, contact Lindsey Grimes, BioZyme Nutrition Coordinator, at (816) 596-8779.

Heat stress impacts cattle performance and costs millions of dollars in annual economic losses. Animal responses to heat stress include reduced dry matter intake, decreased average daily gain, decreased milk yield, decreased fertility and poor reproduction.

As Figure 1 reflects, the severity of heat stress is commonly estimated by temperature-humidity indexes (THI).

Some have hypothesized that it is not just the extent of heat stress alone that affects animals, but also the duration of the heat stress. This is supported by anecdotal evidence from the field, where it is commonly observed that adequate night cooling reduces the impact of heat stress during multiple-day periods of elevated temperature and humidity.

It is also presumed that the minimum threshold where animals begin experiencing heat stress is a function of the production level of the animal. For example, in growing steers the threshold is considered to be a THI of 84, whereas in a high producing lactating dairy cow the threshold will be considerably lower, starting at a THI of 70. At the same ambient temperature, a higher-producing dairy cow will have to dissipate more heat to the environment than a lower-producing cow of the same size.

In addition to reduced performance, physiological responses to heat stress include increased respiration rates and body temperatures elevated above 39°C (102.2°F). Body temperature rises when cows are no longer able to dissipate body heat to the environment, and is a very sensitive indicator of heat stress. Cows may exhibit panting and drooling as behavioral and physical responses to heat stress.

Feeding Amaferm^® during heat stress has multiple benefits including improved digestibility, increased energy availability, improved rumen function and decreased loss of performance. The improved digestibility observed with Amaferm provides more energy to the animal during heat stress when intake is reduced. Amaferm has been shown to improve milk yield performance with lactating cows under heat stress (Figure 2) and help maintain body condition (Chiou et al., 2002). The benefits of Amaferm in dairy cattle production can also be translated to beef brood cow and feedlot performance. In summary, feeding Amaferm during heat stress can:

• Increase digestibility.
• Increase energy availability.
• Improve microbial protein yields.
• Help stabilize rumen function and pH due to stress disrupting feeding patterns, which can lead to consumption of unusually large meal size.
• Improve milk yields and help maintain body condition.
• Improve overall performance.

Calving season is here for many producers and right around the corner for others. It is time to begin thinking about health protocols for newborn calves. Those first few weeks of life are a stressful period in young calves’ lives, but by ensuring they receive the proper nutrition, vitamins and minerals, producers can make sure calves achieve a strong start.

Healthy calves start with healthy mother cows. At this stage of the cow’s life, it is important that she receives a nutrient-rich diet with the appropriate amount of protein. By working with your BioZyme Area Sales Manager or one of the nutritionists, they can assist with forage testing and ration balancing to get cows on the right track.

We recommend a high-quality breeding mineral like Concept•Aid^® be fed a minimum of 30 days prior to calving through breeding season. Concept•Aid is high in vitamin E and selenium, which are important for colostrum quality. Colostrum production begins as early as 4-5 weeks prior to calving, so you want to make sure that the cow is ready. Once the calf is born, it is important that it receives colostrum within the first 24 hours. However, for maximum immunity, receiving colostrum within six hours is best.

Encouraging your customers to give a dose of Vita Charge^® gel or a Vita Charge bolus at birth and/or tagging will help calves more successfully deal with stress. Vita Charge gives the calf a boost of B-vitamins to encourage intake. Vita Charge also contains Amaferm^®, a prebiotic that multiplies the good bacteria in the calf’s stomach. At this point in the calf’s life, it doesn’t make sense to give a probiotic as the calf is a functional monogastric, and therefore, probiotics won’t help the rumen.

As calves begin to mature, putting a Vita Charge Stress Tub in an area where the cows can’t get to it, such as a calf hutch or bedded shed, can provide additional health benefits. In addition to vitamins, minerals and Amaferm, the Vita Charge Stress Tub contains MOS that can greatly help with scour issues and promote overall health.

It is best for your customers to contact their local veterinarian about vaccinations. Recommended vaccinations can vary greatly by geographic region, and a local veterinarian will be able to give the best advice.
