Daily nutrient requirements for maintenance of mature lactating cows. Table 1. Feed and Ingredient Information is presented as Tables of chemical composition and nutritional value for an extensive list of feed nutrient constituents. One exception is that the NRC calculates the crude protein requirement for some classes of cattle to be less than 7 percent. These values were adapted from the National Research Council’s (NRC) Nutrient Requirements of Beef Cattle publication. The tables which follow give data for proximate composition, calcium and total phosphorus, and digestible energy. Nutrient Composition of Byproduct Feeds † Adapted from NRC (1996) and Preston (2014) Feed Composition Tables 2013 Feed Composition Tables. Fed.). 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. Coefficients for a given con- stituent and feed vary considerably and unless a large number of At the end of this appendix, tables for amino acid composition, extracted from NRC (1983) have been provided. In the accompanying table, certain chemical constituents are shown. they are fed.

Table 1. The tables include Nutrient, Mean, Number of Samples (n), Standard Deviation (SD), Coefficient of Variation (CV), and 10th / 90th Percentile values for Energy and Mineral components. Nutritional Research Council (NRC) does not provide carbohydrate recommendations for adult dogs, but they have a nutritional requirement for glucose. This is a function of its chemical composition and the ability of the animal to derive useful nutrients from the feed. The response of cattle and sheep when fed a feed, however, can be termed the biological response to the feed in question. Con- siderable latitude must be permitted in the choice of digestibility coeflacients suitable for general use. refers to the energy content of the feed; either may be used in formulating rations. in Tables 11.4 and 11.5.

National Swine Nutrition Guide tables on nutrient recommendations, ingredient composition, and use rates Swine nutrition and feeding management is a complex process. * Body Wt. Feed is the largest single item among the costs of producing pork, historically accounting for about 60% of all costs in farrow-to-finish systems. Complete composition data for many feeds in the feed library were not available, therefore, the computer program calculates only the amounts of DE, CP, Ca, P, Na, Cl, K and lysine provided by the dietary ingredients.

Nutrient Requirements of Goats:Angora, Dairy, and Meat Goats in Temperate and Tropical Countries; Committee on Animal Nutrition, National Research Council 8.5 x 11, 84 pages, 1981. Some data on the essential fatty acid composition of several lipids are given in Appendix V, under 'Lipids'. Modifications in the NRC Beef model (1996, 2000) and NRC Dairy model (2001) software the chemical composition data of table 1 show differences from other published tables due to selections made in the compilations. Table 5 shows the mineral composition of feeds commonly used in dairy cattle rations (U.S. The nutrient concentrations of selected Alberta-grown whole barley grain (Hordeum vulgare L.), three pure hays of alfalfa (Medicago sativa L.), barley, oat (Avea sativa L.), and four pure crop silages of alfalfa, barley, corn (Zea mays L.), and oat were determined and compared with nutrient concentrations of similar forages and a cereal grain reported in the National Research Council (NRC … Subcommitte on Feed Composition, Committee on Animal Nutrition, National Research Council 8.5 x 11, 156 pages, 1982. 42 beefmagazine.com March 2013 Nutrition ENERGY PROTEIN FIBER FEEDSTUFF DM % TDN % NE m NE g NE l (Mcal/cwt.)
