Document Summary
Animals must be able to convert dietary protein into amino acids. Most protein sources used in feeding animals are 75-80% digestible. Plant protein sources can contain various inhibitors that affect protein. The portion of amino acids that are retained by the animal. Aas readily absorbed in the anterior portion of the small intestine. Balance of amino acids being absorbed affects the biological value of the pro. Proportions of available amino acids present in the protein source, especially the es biological value. Number of grams of body weight gain of an animal per unit of protein consu. Efficiency of growth measured by comparing body nitrogen uptake resulting resulting from feeding a comparable group of animals a protein-free diet from. Computed by multiplying the digestibility of a protein by the bv. To obtain an ideal balance of amino acids at the most economical price. Metabolized and used as a source of energy. Quality is less important to ruminants than simple stomached species.
