Mineral Nutrition for Grazing Beef Cows: Intake and Quality

When beef cows are grazing over the next few months, nutrient requirements for energy and protein are generally met by the forage, and thus vitamin and mineral supplementation is the primary nutritional concern. Most producers provide free choice mineral to cows during this time and assume that it is providing adequate amounts of the necessary minerals. However, there are some important factors to consider to ensure mineral requirements are met.

First, and most important is mineral intake. Cows do not consume free choice mineral consistently throughout the summer grazing season. Some believe that cows will consume what they need, but that is not the case. Salt intake is the driving factor affecting mineral intake. If cattle are consuming significant amounts of salt in the forage, then they will decrease intake of high salt mineral and vice versa if they are consuming small amounts of salt in the forage. Adjusting the amount of salt in the mineral is the best way to regulate intake, and if plain white salt is provided mix it with the mineral otherwise cattle will consume the salt instead of the mineral.

Availability and location of clean water can also impact mineral intake. Mineral supplements generally have a high salt content, and cattle will want a drink after consuming mineral. And may stop consuming mineral sooner if water is not readily available. Placing mineral feeders relatively close to water sources can help if mineral intake is less than desired, but having mineral feeders too close to loafing areas can result in overconsumption of mineral.

The form mineral is provided can also affect intake. Cows will generally consume less mineral per day when in block form than in loose form just for the simple fact that the amount of mineral consumed per minute is lower with blocks. It is important to provide several blocks at once so multiple animals can consume mineral at the same time. Also, lower intake of mineral blocks means that the mineral concentration in the block should be increased accordingly. Blocks may be a good option during times of the year when cattle want to overconsume loose mineral. Mineral tubs on the other hand are consumed in greater amounts than loose mineral by cows, generally by design as tubs usually provided added protein and sugars to aid in digestion of more mature forages. However, the high palatability of tubs can easily result in overconsumption.

Individual cows also do not consume the same amount of mineral with some cows consuming less and some cows consuming more than desired. In a recent study at the USDA-ARS For Keogh Livestock & Range Research Laboratory, there was a 3-fold difference in mineral intake among cows in the herd. Currently, very little is known about the variability in mineral intake among cows and the reasons this variability exists. In this study there was no statistical difference in calf weaning weight or postpartum interval between cows consuming the most versus the least amount of mineral, but there appeared to be a linear trend that as cows consumed more mineral, calf weaning weight decreased. There could be several reasons for this that need to be explored before management strategies can be developed.

The most important aspect of mineral intake is to monitor intake. Adjustments to salt content or mineral form cannot be made accurately if the current level of mineral intake is not known. The date mineral is delivered, amount of mineral delivered, and the number of cows in the herd should recorded to compute the average daily mineral consumption. Mineral intake can then be managed accordingly.

The second factor of mineral supplementation is the quality of the mineral, which includes concentration of individual minerals in the supplement, bioavailability of the mineral sources and mineral deficiencies of the forage, all of which affect the ability of the mineral supplement to meet the mineral requirements of the cow herd. Soil mineral content and plant availability, forage species, and forage maturity affect the mineral content of the forage consumed by the cow. Different regions of the US differ in mineral content of soils resulting in different mineral content of forages grown in that region. Other characteristics of the soil, such as clay content and pH, also affect the availability of soil minerals for uptake by the forage plant. Thus, mineral supplements should be formulated for the region of the country where they will be used.

Forage species also differ in mineral content even when grown in the same soil. In broad terms, legumes are different than grasses, and cool-season grasses are different than warm-season grasses. For all forage species, mineral content is generally greater in lush growing plants than more mature plants. Additionally, more mineral is associated with the plant cell wall, which is the less digestible fraction, as the forage plant matures. The proportion of individual minerals also changes as the forage plant matures. Thus, the concentration of individual minerals in the supplement should change in different times of the year.

There are several sources of minerals that can be used in manufacturing a mineral supplement: oxide, sulfate, chloride, and organic. These sources differ in bioavailability, which is the ability of the mineral to be absorbed and function in the body. Generally, organic sources are the most bioavailable, but the increase in bioavailability compared to the other sources is not equal among mineral elements. For example, organic selenium is 40% more bioavailable than selenite, but organic manganese is only 25% more bioavailable than manganese sulfate. Sulfate and chloride sources have similar bioavailability, and oxide sources have very low bioavailability with the exception of magnesium oxide, which is similar to magnesium sulfate or magnesium chloride. Knowledge of the source of the mineral element in the mineral supplement can be important, especially in areas where mineral antagonists are prevalent in forage plants.

There are several factors to consider and manage when it comes to mineral supplementation of grazing beef cows. Make sure that the mineral supplement is formulated for the soils and forages in the appropriate region of the US. Monitoring mineral intake is the most important aspect because even the best formulated mineral cannot meet cow requirements if the mineral is not consumed in the proper amount.

Role of Research for the Future of Beef Production

Known cattle production efficiency and health problems, new challenges and opportunities, changing economic and societal situations, and human curiosity all drive the need for beef cattle research. Recognizing the need for research means that cattle producers, scientists, and many other stake-holders agree that there are opportunities to improve diverse areas of cattle health and well-being, production, and economics. From a veterinary perspective, investigations of management, genetic selection, and technology interventions to increase reproductive efficiency, improve forage utilization, avoid disease, and enhance disease treatment effectiveness are exciting areas of research. Because of ongoing research, veterinarians and beef cattle producers can look forward to having more information and new tools to improve cattle health and well-being, production efficiency, and long-term sustainability.

Careful and accurate observation of cattle and their environments plays an essential role in scientific research, but observation alone will not lead to new understanding about how to improve cattle production. Research combines careful observation with specific strategies to account for the natural variation that occurs when different individual cattle are treated identically, and with methods to limit unintended biases from interfering with a true interpretation of how cattle behave and respond to different environments and treatments.

 The reason that cattle research must be carefully planned is that cattle health and well-being and production efficiency are influenced by a complex interaction of many biologic and economic factors. The biologic factors include: cattle genetics, forage quality and availability, the presence and types of different disease risks, the varying impact of temperature, humidity, and other environmental features on different cattle, how cattle respond to the stresses they encounter, and many other factors. Observations of relatively few animals or observations taken over a short period of time often fail to allow a person to accurately understand the many factors that interact to cause an outcome.

Because of these challenges, even well-planned research projects can only answer one or two fairly limited questions at a time. But a long-term approach to solving the important questions facing cattle veterinarians and producers through a series of studies carried out on a variety of cattle types, ages, and environments, slowly allows researchers to build an understanding of the interacting factors that can be managed to improve cattle production.

Some of the interesting areas being researched now include: investigations into the role that genetics plays on which cattle are most likely to be resistant to various diseases, research comparing the ability of diagnostic tests to more accurately identify cattle that can spread disease to other animals, and comparisons between different methods of preventing or treating diseases that commonly affect cattle. In addition, there are very interesting investigations of how cattle management can enhance utilization of available forages, and how nutrition at one stage of life affect other stages of life. There are also exciting areas of research to improve reproductive efficiency of cattle by investigating more accurate ways to sort bulls into high- and low-reproductively sound classifications, to enhance the fertility of cows, and to reduce the risk of abortion in pregnant cows. Many studies are looking for ways to utilize new technologies such as computers, genetic testing, GPS tracking, and miniature robots to improve cattle production. Other areas of study include investigations of cattle behavior, grazing patterns, rumen function, growth efficiency, response to vaccinations, and resistance to disease based on time-tested production methods.

Regardless of the area being studied, research is a slow, step-by-step process with very few leaps in new knowledge. But the results of multiple well-planned research studies evaluated over time and across different production situations gradually adds to our understanding of the factors that impact cattle health and well-being and production efficiency. Current cattle producers and veterinarians benefit from many decades of research that has provided valuable strategies and tools that are used daily. The research that is being conducted today will provide additional breakthroughs in the coming years.

Drought-Related Reasons to Wait on Spring Turnout

Some places of the eastern Great Plains have received some rain, and the drought monitor looks a little better, but much of the Great Plains and Intermountain West are still in moderate to severe drought and areas of extreme drought are increasing. Warmer temperatures and a little moisture have caused some pastures to begin greening up, but without additional rain plant growth will be limited.

Turning out on these pastures too early will have detrimental effects on plant growth. Cattle will graze off the leaf area limiting the ability of the plant to photosynthesize sugars, which will require the plant to pull sugars from the roots. Without rain to stimulate more leaf growth the plant will rely more heavily on nutrient reserves in the roots, possibly decreasing the root zone and capacity to pull the limited moisture from the soil. This stunting of plant growth and reduction of the root zone will have negative effects on forage production in future years.

So, what can you do? Keep cattle off the pasture as long as possible with the optimism of more rain. Continue to feed hay or find other feed resources that may let you economically extend the winter feeding period. In a previous newsletter we discussed limit feeding cows. The difficulty is that lactating cows have their greatest nutrient requirements during this time from calving to rebreeding. Thus, feed expenses will be greater than the last few months. In late gestation, hay with total digestible nutrients (TDN) of 57% and crude protein (CP) of 10% will meet the nutrient requirements of a 1300-lb cow (Figure 1). But in early lactation, the same cow producing 20 lb of peak milk will require TDN of 59.5% and CP of 10.5%. To make up this nutrient deficit will require 4.5 lb/day of a supplement that has TDN of 75% and CP of 20%.

As Dr. Larson, likes to say “There is something magical about green grass.”. As a nutritionist, I am not sure about the magic, but early spring grass has a nutrient profile that will promote fleshing of early lactation cows (Figure 1). Cows that are in a positive energy balance from calving to rebreeding typically return to estrus sooner and rebreed better. There will be tough decisions to make this spring, because neither spring turnout or continued hay and supplement feeding are likely to be without consequences.

Cattle Handling Facilities

Many animal health interventions require that cattle be gathered to a handling facility that allows individual animals to be separated from the rest of the herd and confined in a squeeze chute. In situations where all the cattle in a pasture or pen are healthy and are going to be handled to give animal health products such as vaccines or parasite control, or to monitor body condition score or pregnancy status, the facilities have to be large enough to accommodate all the cattle in the group. When a few cattle from the herd need to be examined or treated for disease, the facilities have to allow safe and efficient separation of the desired animals from the rest of the herd and then adequate restraint in a squeeze chute to allow access for close inspection of areas on the animal’s body that require treatment. Cattle should be able to be moved from the pasture or pen to the working area and through the handling facilities with a minimum of stress to both the cattle and producer.

Because cattle are prey animals and can easily react to contact with people and dogs with a ‘fight or flight’ response, it is important to prevent cattle from becoming agitated when being handled. Cattle are herd animals and tend to become fearful when left alone. Strategies to minimize fear include moving cattle slowly and quietly and always moving cattle in small groups. Do not use dogs to move cattle in confinement, and minimize the use of electric cattle prods. Because cattle balk at moving or flapping objects, the crowding pens, single-file alley, and loading ramp should be monitored to make sure that nothing within the line of sight could cause them to react. As cattle are moved from the pasture or pen toward the working facility, do not over-crowd them. Never fill the crowd pen – rather only add enough cattle to be about one-half of capacity, and then do not “crush” the cattle with the crowd gate to force them into the single-file alley. The crowd gate is used to follow the cattle, not to shove up against them. Cattle should have room to move around in the crowd pen with the only visible route of escape being the alley. If a lone animal refuses to move, release it and bring it back with another group.

Cattle have excellent wide-angle vision (in excess of 300 degrees) due to the wide position of their eyes and can see behind themselves without turning their heads. And while cattle do have depth perception, they have difficulty seeing the size and shape of objects at ground level when their heads are raised. To see depth near the ground, cattle have to lower their head, perhaps explaining why cattle balk at distractions at ground level. Because contrasting patterns caused by fence or panel shadows will cause balking, lighting considerations are important for moving cattle smoothly through handling facilities. In addition, cattle in a dark area will move towards a dim light but they tend to balk if they have to look into the sun or a bright light. Because cattle may refuse to enter a dark, indoor working alley from a bright, outside crowding pen, it may be necessary to extend the alley outside the building or to cover the crowding area to prevent sharp contrasts in lighting that cause cattle to balk at important points in the handling facility.

Cattle like to maintain visual contact with each other, so in most situations, the single-file alley leading up to the squeeze chute should be at least 20 ft. long (30 to 50 ft. for larger facilities) to allow each animal to see others ahead of it. Don’t force an animal into a single-file alley unless there is plenty of room. If cattle see a dead-end, they will most likely balk, therefore, blocking gates in a single-file alley need to be “see through” so cattle can see the animals ahead.

To protect all the people handling cattle, the corrals, working facilities and chutes must be in good repair and must match the operation and cattle. Gate latches and latches on the squeeze chute (head-catch and squeeze) must have scheduled, proper maintenance because slipped latches are very dangerous. All persons using the squeeze chute should know where the pinch points are, and the arc of movement of squeeze bars and head catch handles. Pipes slid behind cattle to serve as a back-stop are dangerous because an animal moving either forward or backward rapidly before the pipe is fully engaged can trap a person between the pipe and the side of the alley or chute. And to prevent being injured directly by an animal, do not get in the crowding area or alley. Also, the working area should be easy to clean and provide non-slip flooring in the crowd pens, alleys, chutes, and the exit from the chute.

While good working facility design, construction, and maintenance are important for safe and efficient cattle handling, the people handling the cattle probably have the greatest impact on the level of stress inflicted on the cattle and handlers and the ease that cattle move through a facility. Most cattle producers know of people who handle cattle particularly well (as well as people at the opposite extreme). We use terms like cow-sense, common-sense, or stockmanship to describe people who are able to observe cattle behavior accurately and then respond to that behavior so that cattle move exactly where the handler wants them to move. Although there may be some in-born personality traits or skills that make some people naturally better cattle handlers, good cattle-handling training that emphasizes unlearning bad habits and learning low-stress cattle handling habits can benefit anyone who routinely works with cattle.

            It is easy to recognize that handling cattle is required for many, if not most, animal health procedures. In order for health and production management interventions to provide the greatest benefit to a cattle herd, the cattle must be handled through good facilities quietly, efficiently, and with minimal stress.

Limit Feeding Cows in Drylots

Dry weather across most of the central plains since last fall is creating signals, that a major drought may be on the horizon for this grazing season. The reliance on pasture of most cow herds means that some hard decisions will likely need to be made. The primary decision revolves around feed sources to replace hay or pasture or stretch hay or pasture. Several commodities can be used to replace or stretch hay and pasture; mostly by-products from grain milling.

Two key nutrients are total digestible nutrients (TDN) and crude protein (CP). TDN is the measure of energy used with beef cows, and is the nutrient needed in greatest quantities to maintain performance. CP is the next nutrient needed as far as quantity. Feeds have different concentrations of TDN and CP, and have different costs. Figure 1 illustrates the cost per unit of nutrient of common commodities, which is an effective way to compare feed cost. Hay at $100/ton has the lowest cost per unit of TDN and CP. However, when hay reaches $200/ton, which may happen in severe drought situations especially if trucking long distances, it has the greatest cost per unit of TDN and second greatest cost per unit of CP. Additionally, hay supplies may be limited even if hay is the cheapest source of nutrients.

Currently, corn at $6.50/bu is the least expensive source of TDN followed by soybean hulls at $210/ton and dried distiller’s grains at $280/ton. Dried distiller’s grains is also the least expensive source of CP making it a valuable feed. Therefore, a mixture of corn, soybean hulls, and dried distiller’s grains would be an economically and nutritionally viable option to replace or stretch hay or pasture.

A 1300-lb cow in late lactation requires about 14 lb of TDN and 2.10 lb of CP per day. A mixture of 15% dried distiller’s grains, 20% corn, 35% soybean hulls, and 30% hay fed at 20 lb/day (80% of ad libitum intake) would meet the TDN and CP requirements of the cow. The calf will consume about 4 lb/day of hay or pasture for a total of 24 lb/day. If calves are weaned early at 4 months, 15 lb/day will meet the TDN and CP requirements of an early gestation, dry cow, but then the calf will eat 7 lb/day of mixed ration to gain 2 lb/day for a total of 22 lb/day.

If the price of hay is $100/ton, it is more economical to feed the lactating cow with a nursing calf at $2.11/day, but if the price of hay is $200/ton, it is more economical to wean the calf early and feed a dry cow plus calf at $2.49/day. If the price of hay is $150/ton, then both management options cost the same. This economic calculation is based on the prices of feeds used, and the tipping point will depend upon local hay and commodity prices.

Even though feeding commodities to beef cows and calves can be an economically viable option, it requires the correct management. Feeding large amounts of commodities to beef cows who have full access to pasture or hay will not save much hay and result in greater feed costs. The cost savings is in the fact that less total feed (reduction in hay intake) can be fed to maintain cow performance, which requires limiting access to pasture or hay. It does not require a fenceline feedbunk and mixer wagon. Use the resources you have such as labor, hay intake can be limited by restricting access to the round bale feeder by moving cows in and out of the pen with hay feeders. Early-weaned calves also require more managerial skills in that they are more susceptible to disease and require daily feeding and observation. The rumen of these young calves is not developed enough to effectively digest long-stem hay, and they require moderate energy diet based on grains and commodities to perform well.

Finding alternative feed sources during a drought can be challenging especially if the drought is widespread and hay has to be hauled long distances. Grains and byproduct commodities are viable alternatives that can be used to maintain performance of the cow herd, but feed costs are going to be greater. Additionally, limit feeding moderate concentrate diets to beef cows and managing early-weaned calves requires the correct facilities and managerial skills.

Beef producers have many demands on their time and attention. One of those demands is to achieve excellent health for their herd. In general, cattle can remain healthy in a wide variety of environments and when under a variety of stresses. However, young calves, cows around the time of calving, and cows and their fetuses in the early stages of pregnancy are more at-risk for experiencing health problems than cattle of other ages. In addition, individuals or herds that have to deal with more than one problem at the same time can have severe health problems.

In my opinion, the secret to excellence in herd health is to focus on time-tested aspects of animal husbandry while utilizing some aspects of more modern technology.  The term “animal husbandry” may have gone out of favor in some circles, but it describes the care and feeding of livestock based on good observation skills and a daily commitment to the health and welfare of the animals. Focusing on maintaining good forage availability, good body condition of cattle, and a clean environment that allows for protection from severe weather and predators are long-standing attributes of the best cattle producers. In the past century, additional tools have become available to help improve cattle health. These include advancements in forage management, feed evaluation, internal and external parasite control, vaccines for disease prevention and control, tests for the identification of cattle carrying contagious organisms, and genetic selection to reduce the risk of calving difficulty and other common problems. Combining these modern technologies with age-old husbandry skills allows today’s beef producer to achieve a level of health for their cattle herds that was not possible in the past.

Good cowherd nutrition is built on the foundation of good forage production and management. Abundant growing grass is a fantastic feed that usually results in excellent health of grazing cattle. Cattle can use a wide variety of plants for a healthy diet, but if drought or over-stocking reduces the amount of forage that cattle can consume, health problems are likely to follow. All forages are deficient in salt and providing salt throughout the year is necessary in all parts of the U.S. In addition, other minerals are also needed in cattle diets, but in many areas the available forages provide all or most of a herd’s other mineral needs. In areas or pastures with known mineral deficiencies, specific minerals such as phosphorus, copper, zinc, selenium, or other minerals will need to be supplied. During the winter or other times of the year when forage is dormant, protein and other nutrients may need to be supplemented to ensure that the herd is receiving an adequate diet to maintain body weight and optimum health. Research at universities and other locations over the past several decades have provided nutritionists and veterinarians with valuable information and tools to balance forage-based diets for cattle at the different stages of production such as growth, pregnancy, and lactation.

In addition to a commitment to provide adequate forage and supplements, the other aspect of animal husbandry excellence that has been passed down through the ages is to provide an environment that is clean and gives protection from weather and other stresses. Because cattle are housed outdoors, the natural occurrences of dust and mud are not completely avoidable; but throughout time, the best animal caretakers provided excellent environments for their cattle given the rainfall, snow storms, and other weather events that are common for their area. The best mud-control strategies for cattle on pasture is to make sure that cattle spread out and do not congregate in an area where the combination of rainwater or snow-melt and the hoof action of cattle result in deep mud. The amount of space needed to minimize the risk of problems due to mud will depend on the expected rainfall patterns for an area. Making sure that shelter as well as water, salt, and feed sources are spread to various parts of a pasture will keep cattle from spending too much time as a group in a small area. Mud control strategies for cattle that are housed in drylots include good design and construction of pens to allow water drainage, and frequent scraping to maintain a good pen surface. In areas of the country that can experience severe winter storms, cattle need to be able to find natural or man-made wind-breaks and to have access to areas with good draining that are free of standing water and mud.

One of the greatest advancements for cattle and cattle producers that modern technology has provided has been in the area of parasite control. Throughout history, worms (or internal parasites) and flies and other insects have caused tremendous discomfort, disease risk, and production loss for cattle. Appropriate use of chemicals to interfere with the life-cycles of parasites allows cattle producers to remove much of the negative effect of these pests. Because parasites are very numerous and have the ability to adapt to changing environments and risks, they continue to cause health and production problems. Internal parasites cause more severe problems in young cattle and in cattle that live in warmer parts of the country that have larger parasite populations because they lack the benefit of killing winter temperatures. By working closely with a veterinarian, cattle producers can implement strategies to control parasites for the short-term while making sure that they don’t contribute to the development of pests that resist chemical control.

The knowledge and technologies that make accurate EPDs possible provide a tremendous benefit to cattle producers by giving them tools to reduce the risk of calving difficulty. The period of time with the greatest risk for both calves and their dams is at and shortly after calving. Difficult births cause direct problems for both the dam and the calf and even if a calf survives a difficult birth, the stress of that event as well as reduced colostrum intake combine to increase his risk of death due to scours, navel ill, or pneumonia during the first few months of life. Through good bull selection and heifer selection and development, modern beef producers have tools to reduce the risk of difficult calving that earlier generations would envy.

And finally, an over-arching strategy to achieve excellence in herd health includes using vaccines to reduce the risk and severity of some important cattle diseases, and antibiotics and other modern drugs to treat illnesses and injuries that affect cattle. These advancements in disease treatment and prevention options are valuable, but they must be used correctly and as enhancements and not replacements for good cattle husbandry.  Following Beef Quality Assurance (BQA) guidelines to ensure that all products are administered using the proper injection sites, injection routes (under the skin, in the muscle, into the vein, etc.), dosages, and withdrawal times is a critical step when beef producer commit to excellence in herd health.

Spring Rains Bring Green Grass and Deep Mud

It has been abnormally dry across much of the cattle feeding country with moderate to severe drought in many places. Dry weather has made for good cattle feeding conditions across cattle feeding country. Typically, March and April are two of the wettest months of the year, which will be a blessing to most of the central plains and western US bringing spring pasture. But these wet months can also be times of extreme mud in dry lot situations. Cattle feeders in the Corn Belt are more likely to have issues with deep mud that can negatively impact cattle performance. Mud depths of 4 to 8 inches can decrease feed intake up to 15% primarily because cattle make fewer trips to the feed bunk. Mud-coated hair also does not insulate cattle well thus more energy is required to maintain body temperature. All of this can decrease daily gain 10 to 20% and increase cost of gain 15 to 25%. Given the dry conditions, it likely that interventions could still be used to minimize the negative effects of mud in the coming months. Correcting pen drainage issues, especially around the feed apron and water trough, and rebuilding mounds would be two important strategies to minimize the negative effects of mud.
