Cattle Today – Features Articles on Best Practices for Cattle Nutrition, Including Advice on Pasture Management and Supplemental Feeding

Introduction

Cattle production is a complex enterprise that requires attention to genetics, health, reproduction, and most importantly—nutrition. Proper nutrition is the cornerstone of a successful beef or dairy operation. It not only ensures optimal growth and productivity but also contributes to the health and well-being of the herd. In recent years, publications like Cattle Today have consistently offered practical, research-backed insights into cattle nutrition—focusing particularly on pasture management and supplemental feeding.

This article aims to distill best practices featured in such publications, offering cattle producers a detailed guide to optimizing cattle nutrition through modern methods of forage use and targeted supplementation.

The Importance of Nutrition in Cattle Production

Nutrition directly affects:

• Reproductive efficiency
• Milk production
• Growth rates in calves
• Immune response
• Longevity of breeding stock

Cattle nutrition is typically categorized into:

1. Forage-based (pasture or hay) diets
2. Grain or concentrate supplementation
3. Minerals and vitamins

Finding the right balance between these categories depends on pasture quality, the age and purpose of the cattle (e.g., lactating cows, finishing steers, or replacement heifers), and environmental factors such as weather and soil quality.

Best Practices in Pasture Management

A significant portion of cattle nutrition comes from forages. Effective pasture management can not only improve forage availability but also reduce feeding costs.

1. Rotational Grazing

• Definition: Moving cattle between different pastures (or paddocks) to allow grazed areas time to regrow.
• Benefits:
• Prevents overgrazing
• Promotes regrowth of forage species
• Enhances soil fertility and reduces erosion
• Implementation Tips:
• Divide pastures into 4–10 paddocks
• Allow 21–30 days rest between grazing
• Use mobile fencing for flexibility

2. Soil Fertility and pH Management

• Soil Testing: Should be conducted annually to determine lime and fertilizer needs.
• Lime Application: Adjusting soil pH to 6.0–7.0 improves nutrient uptake by grasses and legumes.
• Fertilizer Use: Nitrogen boosts grass growth; phosphorus and potassium support root development and forage quality.

3. Weed Control

• Integrated Approach:
• Mechanical (mowing)
• Chemical (herbicides)
• Grazing pressure (targeted grazing)
• Timing is critical: Herbicides are most effective during early growth stages of weeds.

4. Forage Diversity

• Warm-season grasses (e.g., Bermuda, switchgrass) and cool-season grasses (e.g., fescue, ryegrass) offer year-round grazing.
• Legumes (clover, alfalfa) provide natural nitrogen and boost protein content.

Supplemental Feeding: When and What to Feed

While high-quality pastures provide a solid nutritional base, supplementation is often necessary to meet specific nutritional demands—especially during:

• Winter
• Drought
• Breeding and lactation
• Rapid growth phases

1. Energy Supplements

• Provided when forage is low in total digestible nutrients (TDN).
• Common options:
• Corn
• Barley
• Oats
• Molasses

These are particularly important for lactating cows and finishing cattle.

2. Protein Supplements

• Needed when crude protein in forage drops below 7–8%.
• Sources:
• Cottonseed meal
• Soybean meal
• Distillers grains
• Urea (non-protein nitrogen) – use with caution

Protein is vital for rumen microbes, which are key to digesting fibrous forages.

3. Mineral and Vitamin Supplements

• Cattle require:
• Calcium (Ca)
• Phosphorus (P)
• Magnesium (Mg)
• Selenium (Se)
• Salt (NaCl)
• Vitamins A, D, E
• Delivery methods:
• Free-choice mineral blocks or loose minerals
• Injectable or feed-mixed options for specific deficiencies

4. Ionophores

• Feed additives like monensin and lasalocid improve feed efficiency and weight gain.
• Also help reduce methane emissions from digestion.

Water: The Forgotten Nutrient

Water intake drives feed intake. On average, a 1,000-pound cow drinks 10–20 gallons/day, and even more in hot weather. Poor water quality or limited access leads to decreased intake of both forage and supplements.

Water Management Tips:

• Clean tanks regularly
• Ensure easy access from all paddocks
• Monitor flow in automatic systems

Evaluating Body Condition Score (BCS)

Monitoring cattle using BCS (scale of 1 to 9) helps identify nutritional deficiencies early.

• Target BCS:
• Cows at calving: 5–6
• Heifers: 6
• Bulls: 5.5–6.5

Thin cows may have trouble breeding, and overconditioned cattle may have calving difficulties.

Seasonal Strategies for Cattle Nutrition

Spring & Summer

• Maximize grazing
• Rotate pastures every 5–7 days
• Monitor for fescue toxicosis

Fall

• Prepare for winter with stockpiled forages
• Start mineral supplementation for breeding cows

Winter

• Feed hay + energy/protein supplements
• Test hay for nutrient content

Best Practices in Cattle Nutrition: Pasture Management and Supplemental Feeding

Cattle nutrition is a multifaceted discipline that involves not only providing the right feed and supplements but also managing pastures effectively to ensure that the animals receive adequate nutrition throughout the year. One of the most important aspects of cattle nutrition is the management of pastures, which serve as the primary source of feed for most cattle. Well-managed pastures can support cattle health, productivity, and overall performance while reducing the need for expensive supplemental feed. However, pasture quality can fluctuate based on factors such as seasonal changes, soil fertility, grazing pressure, and weather conditions. This is where rotational grazing practices play a significant role in ensuring that pastures remain productive and provide adequate nutrition to cattle. Rotational grazing involves moving cattle between different paddocks or sections of pasture, which allows grazed areas to recover and regenerate before being grazed again. This method prevents overgrazing, which can lead to pasture degradation and a decline in forage quality. By rotating cattle regularly, producers can help maintain the health of their pastures, promote better soil fertility, and increase the productivity of the land. Additionally, rotational grazing can help extend the grazing season, reducing the need for supplemental feed during periods of pasture scarcity. When implemented correctly, rotational grazing not only improves pasture quality but also supports the environmental sustainability of the operation by preventing soil erosion and improving water retention in the soil. Pasture management goes beyond simply rotating grazing areas, however. Effective soil management is equally important in ensuring that pastures remain healthy and productive. Soil fertility directly impacts the quality and quantity of forage that can be produced. Regular soil testing is essential to determine the nutrient content and pH levels of the soil, which in turn informs decisions about lime and fertilizer applications. Lime is commonly applied to raise soil pH to an optimal level of 6.0 to 7.0, which enhances nutrient availability to plants and improves the effectiveness of fertilization. Fertilizing with the appropriate blend of nutrients, such as nitrogen, phosphorus, and potassium, is also essential to maintain healthy pastures. Nitrogen, for example, is critical for promoting grass growth, while phosphorus supports root development, and potassium helps improve plant resilience to stress. In addition to these macronutrients, pasture plants also require a range of micronutrients like calcium, magnesium, and sulfur, which play important roles in plant metabolism and overall health. Applying the right combination of fertilizers based on soil test results ensures that pastures have the necessary nutrients to support healthy plant growth and, by extension, provide the best nutrition for cattle. Along with proper soil management, maintaining forage diversity is a key strategy for improving pasture quality. Different types of grasses and legumes offer various nutritional benefits, and having a diverse mix of species in a pasture helps ensure a more consistent and reliable forage supply. Cool-season grasses, such as ryegrass and fescue, provide high-quality forage during the spring and fall, while warm-season grasses, like Bermuda and switchgrass, thrive in the summer and provide valuable grazing when cool-season grasses slow down. Incorporating legumes like clover and alfalfa into pastures is also highly beneficial because legumes fix nitrogen in the soil, reducing the need for synthetic nitrogen fertilizers and improving the protein content of the forage. Legumes also provide cattle with more digestible and protein-rich forage, which is especially important during times of high nutritional demand, such as lactation or rapid growth phases. Alongside effective pasture management, supplemental feeding becomes necessary at times when natural forage is insufficient to meet the nutritional requirements of cattle. Supplemental feed can help address gaps in nutrition caused by seasonal changes, drought, or poor forage quality. Energy supplements are often used to ensure that cattle receive enough calories, particularly when pasture quality is low in energy or during times of higher demand, such as in the winter or during lactation. Common energy supplements include grains like corn and barley, which provide easily digestible carbohydrates that support weight maintenance, growth, and milk production. In addition to energy, protein supplementation is often required, especially when forage protein levels are inadequate. Protein is essential for growth, reproduction, and milk production, and deficiencies can lead to reduced fertility, lower birth weights in calves, and poor performance in finishing cattle. Protein supplements include soybean meal, cottonseed meal, distiller’s grains, and alfalfa hay, all of which are high-quality protein sources. In some cases, non-protein nitrogen sources, such as urea, can be used to supplement protein intake. However, urea should be used carefully, as it requires proper rumen function for effective utilization and can cause toxicity if overfed. Beyond energy and protein, minerals and vitamins are also critical components of cattle nutrition. Cattle require a variety of minerals, including calcium, phosphorus, magnesium, and salt, to support bone health, nerve function, and overall metabolism. Calcium and phosphorus are particularly important during the lactating phase, as they are involved in milk production and bone development. Deficiencies in these minerals can lead to conditions like milk fever or rickets in young cattle. Magnesium is crucial for muscle function and preventing conditions like grass tetany, especially when cattle are grazing lush, rapidly growing pastures that are low in magnesium. In addition to these major minerals, cattle require trace minerals such as selenium, copper, zinc, and manganese for optimal immune function, reproduction, and growth. Providing free-choice mineral supplements, either in the form of mineral blocks or loose minerals, ensures that cattle can access the minerals they need to support their health. Vitamins A, D, and E are also essential for cattle. Vitamin A is critical for vision, immune health, and reproduction, while vitamin D helps with calcium absorption and bone health. Vitamin E acts as an antioxidant and supports immune function, helping cattle resist infections. While some of these vitamins can be obtained through high-quality pasture, supplementation may be necessary, particularly in winter when forage quality is lower. In addition to these basic nutritional requirements, water is arguably the most important nutrient in cattle nutrition. Cattle consume large quantities of water daily—often as much as 20 gallons per day for an adult cow—especially when they are consuming dry feed like hay or grain. Water is essential for digestion, nutrient absorption, and overall metabolism, and without adequate water intake, cattle cannot fully utilize the nutrients in their feed, leading to reduced performance, health issues, and even dehydration. Ensuring that cattle always have access to clean, fresh water is one of the most basic but essential management practices in cattle nutrition. Finally, monitoring the body condition score (BCS) of cattle provides a practical way to assess whether nutritional needs are being met. BCS is a simple visual and tactile assessment of the fat reserves on a cow’s body, with a score range from 1 to 9, where 1 is emaciated and 9 is obese. Maintaining a BCS between 5 and 6 is ideal for most cattle, particularly cows that are about to calve. Cattle that are too thin may require additional feeding to improve body condition before breeding or calving, while overconditioned cattle may need to be fed less to avoid calving difficulties or metabolic issues. By closely monitoring BCS and adjusting feeding strategies accordingly, producers can ensure that their cattle are well-nourished and able to perform at their best. In conclusion, best practices in cattle nutrition are built on a combination of sound pasture management techniques and strategic supplemental feeding. By implementing rotational grazing, ensuring proper soil fertility, maintaining diverse forages, and supplementing with appropriate energy, protein, minerals, and vitamins, producers can meet the nutritional needs of their cattle year-round. Monitoring water intake and body condition score further enhances the ability to manage cattle nutrition effectively. With careful planning and management, cattle can be kept healthy, productive, and profitable, ensuring long-term sustainability for the operation.

Best Practices in Cattle Nutrition: Pasture Management and Supplemental Feeding

Cattle nutrition plays a pivotal role in ensuring the productivity, health, and overall well-being of a herd. For cattle producers, understanding the delicate balance between pasture management and supplemental feeding is crucial for achieving optimal results. Properly managed pastures can significantly reduce feed costs, while supplementation ensures that nutritional deficiencies are addressed, especially when natural forages are insufficient to meet the cows’ needs. As the agricultural world continues to evolve, understanding the science behind pasture management and supplementation, along with their effects on cattle performance, becomes more essential.

At the heart of effective cattle nutrition is pasture management. Pastures are the primary source of nutrients for most cattle operations, but their quality and quantity can vary dramatically depending on a range of factors such as climate, soil type, grazing pressure, and pasture species. The first step in ensuring that pastures provide optimal nutrition is to implement rotational grazing. Rotational grazing is a system where cattle are moved between different paddocks, allowing previously grazed pastures to recover and regrow. This practice not only promotes better forage regrowth but also helps in preventing overgrazing, which can degrade pasture health and productivity over time. The principle behind rotational grazing is to give each pasture enough rest between grazing cycles to allow grass and legumes to regenerate, ensuring that cattle always have access to fresh, high-quality forage. Typically, pastures are divided into multiple paddocks—anywhere from 4 to 10—and cattle are rotated based on the specific forage growth cycle. This method improves soil fertility as well, because it enables natural fertilization from cattle manure without causing long-term depletion of soil nutrients. When done correctly, rotational grazing leads to healthier pastures and reduces the need for supplemental feeding, especially during the growing season.

Another key component of pasture management is maintaining soil health. Healthy soil is foundational to providing nutritious, high-quality forage for cattle. Soil tests should be conducted regularly to determine the nutrient levels and pH balance. Lime may need to be applied to adjust soil pH, as grasses and legumes generally thrive in soil with a pH between 6.0 and 7.0. Fertilization is also essential, particularly in areas where soil fertility has been depleted. Nitrogen, phosphorus, and potassium are the three primary macronutrients that should be monitored. Nitrogen is particularly important for promoting grass growth, while phosphorus aids in root development and potassium helps plants withstand stress. Maintaining the right balance of these nutrients ensures that pastures remain productive and healthy, reducing the likelihood of having to rely heavily on supplemental feed.

In addition to soil health, forage variety is another critical aspect of pasture management. Different species of grasses and legumes provide varying nutritional benefits and growth patterns. Including a variety of species in a pasture can improve its resilience and productivity throughout the year. Warm-season grasses, such as Bermuda grass, switchgrass, and big bluestem, thrive in the summer, offering a reliable source of forage when cool-season grasses slow down. On the other hand, cool-season grasses like fescue, ryegrass, and orchardgrass are better suited to cooler temperatures and offer valuable grazing during the spring and fall. Legumes such as clover, alfalfa, and trefoil are excellent complements to grasses because they fix nitrogen in the soil, improving overall pasture productivity. The inclusion of legumes in pastures not only increases the protein content of forage but also reduces the need for nitrogen fertilization, making it an environmentally sustainable practice.

Despite the best efforts in pasture management, however, there will be times when supplemental feeding is necessary, particularly during periods of nutrient deficiency. This is where understanding supplemental feeding strategies becomes vital. Cattle’s nutritional needs vary throughout the year, depending on the season, stage of life, and physiological condition. For example, during the winter months, pastures may not provide enough nutrients to meet the energy needs of the herd, especially if the pasture has been grazed down during the fall. This is where energy supplements, such as grains like corn or barley, become particularly useful. These energy-rich feeds can help cattle maintain body condition and ensure that they do not lose weight during the colder months when forages are less abundant.

Protein is another key element that may need to be supplemented. Protein is crucial for supporting the growth of cattle, especially for calves, heifers, and lactating cows. The protein content in pasture can drop significantly during certain times of the year, particularly during droughts or when forage quality declines. In these cases, protein supplements such as soybean meal, alfalfa hay, or distiller’s grains can provide the necessary boost to keep cattle growing and productive. Urea, a form of non-protein nitrogen, can also be used in certain feeding regimens to help meet protein needs, but it must be used carefully to avoid digestive disturbances.

In addition to energy and protein, mineral and vitamin supplementation is essential for maintaining the overall health and productivity of cattle. Minerals like calcium, phosphorus, magnesium, and salt are vital for maintaining bone health, supporting metabolism, and ensuring proper muscle function. Cattle also require trace minerals such as selenium and zinc, which play a role in immune function and reproduction. Many minerals can be supplied through free-choice mineral blocks or loose minerals that cattle can consume as needed. Additionally, vitamins A, D, and E are essential for various bodily functions, including immune health, skin integrity, and reproduction. While some of these nutrients can be obtained from pasture, supplementation is often necessary to meet the full requirements, especially when pastures are deficient in certain minerals or vitamins.

One often-overlooked aspect of cattle nutrition is water intake. Water is, by far, the most important nutrient for cattle, as it is involved in nearly every metabolic process, including digestion and nutrient absorption. In fact, cattle can consume up to 20 gallons of water per day, depending on their size and environmental conditions. Without access to clean, fresh water, cattle will not be able to fully utilize the nutrients they consume, leading to reduced feed intake, lower productivity, and increased susceptibility to disease. Water quality should be regularly monitored, as contaminants or poor water quality can deter cattle from drinking enough and impact their overall health.

Lastly, monitoring the body condition of cattle is a critical practice in ensuring that nutritional needs are being met. Body Condition Scoring (BCS) is a system used to assess the nutritional status of cattle on a scale from 1 (emaciated) to 9 (obese). A BCS of 5–6 is ideal for most cattle, particularly cows at calving, as it indicates that they are well-nourished but not overweight. Cattle with too high or too low of a BCS may require adjustments in their feeding regimen, either through more supplementation or a reduction in feed intake.

In conclusion, effective cattle nutrition requires a comprehensive approach that combines good pasture management with appropriate supplemental feeding. By utilizing practices like rotational grazing, soil management, and maintaining a balanced and diverse mix of forages, producers can ensure that their cattle are receiving the proper nutrition year-round. Supplementary feeds, when necessary, should be carefully selected based on the specific needs of the herd, whether for energy, protein, or minerals. Additionally, regular monitoring of water quality and cattle body condition ensures that nutrition is continually optimized. With proper nutrition management, cattle can reach their full genetic potential, leading to healthier animals, better production outcomes, and ultimately, greater profitability.

Summary & Conclusion

Proper cattle nutrition, rooted in strategic pasture management and smart supplemental feeding, is essential for animal productivity and long-term profitability. Grazing systems like rotational grazing, combined with soil and forage management, set the foundation for high-quality feed. When pasture alone cannot meet the herd’s nutritional needs, supplements—from grains to minerals—help fill the gap.

Water access, seasonal adaptation, and regular condition monitoring round out a robust nutrition plan. As highlighted in Cattle Today and similar resources, producers who invest in learning and applying these practices are more likely to enjoy higher conception rates, better weight gains, and healthier herds.
