of feed lot and grass fed beef cattle. Phos-phorus requirements for maintenance are lower Expensive grasslands demand efficient utilization of forages. Calcium and phosphorus requirements are shown in Tables 4 to 12. Table 5 indicates figures for four different calving times. Beef magazine also publishes a Feed Composition … Calcium requirements are similar to those in the 1984 NRC report because new information is not sufficient to justify a change. Visual observations of body condition score and weight change are valuable for assessing cattle response to their diet. Creep feeds with 33% In the accompanying table, certain chemical constituents are shown. practical importance in beef cattle. Nutrient Grass Feed Lot References w-3 fatty acids Higher Lower (11, 15-30, 40, 47, 48) w-6 … • Explain how a balanced and cost effective nutrition program is essential to the success of any beef cattle operation. • Provide tables that list the nutrient requirements of beef cattle. Feeding Recommendations for Beef Cattle Field pea is a very palatable feedstuff for all classes of beef cattle. Nutritional management includes understanding the nutrient composition of feedstuffs and the levels required by cattle for optimal performance. this is a function of its chemical composition and the ability of the animal to derive useful nutrients from the feed. The following table is a general guideline for understanding feed composition, but a feed analysis should be requested to more accurately determine feed value for your situation. the response of cattle and sheep when fed a feed, however, can be termed the biological response to the feed in question. Before each of these nutritional qualities is examined Table 1. Calcium requirements are adjusted to 50 percent true absorption. For more information see Nutrient requirements of beef cattle. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production. Protein, calcium (Ca) and phosphorus (P) requirements are expressed as grams per day. The nutrient composition of by-products varies widely. Nutritional Composition of Feedstuffs for Beef Cattle Gerry Kuhl, Extension Specialist Danny Simms, Former Extension Specialist Cathy Bandyk, Extension Assistant Animal Sciences and Industry Kansas State University Agricultural Experiment Station and Cooperative Extension Service These typical nutritional values are based on 1982-84 National The tables of feed ingredient composition are significantly updated. From the table below it can be determined how much protein a feed is supplying. the table represent averages from numerous different sources, such as the National Research Council’s Nutrient Requirements of Beef and Dairy Cattle publications, commercial laboratories, research trials, and other publications. of thumb in using field pea for beef, dairy, sheep, swine, and poultry. Nutrient Composition of By-Product Feeds. This feed may best be used in diets where nutrient density and palatability are important, such as creep feeds and receiving diets. • Discuss the nutrient requirements of beef cattle. Knowing the forage’s nutrient composition enables one to calculate the nutrients a cow gets from the grazing, as a percentage of her total requirement. This will depend on the time of the year she calves, as the nutrient availability varies considerably within the calendar year. Potential nutritional differences between feed lot and grass fed beef.
