Document Summary
Energy evaluation of feeds (pg243-246, figure 15. 4) Monosaccharides (sugar): least complex, contain 5 or 6 carbons. Complex: protein that contains additional non-amino acid substances, such as. Lipid (lipoproteins: limiting amino acids: aa that are not provided in sufficient quantity to allow for the normal synthesis of a protein. Essential: must be provided via dietary means, or in the case of ruminants, via microbial action. Micro: trace; required in smaller amounts: vitamins: organic nutrients needed in very small amounts to provide for specific body functions in the animal (16 of them) Review questions: compare and contrast roughage and concentrate feeds. Cereal grains, oil meals, molasses, dried milk products. A hay sample measuring 15% and dm of 90% would have a cp on a as-fed basis of: . 09 (12) -3=9% digestible protein: discuss the importance of by-product feeds to the livestock and poultry industries, nutritional composition, cost competitiveness. Digestive tract sizes and capacities of mature ruminant animals.
