Chemical composition and availability of nutrients in ingredients for poultry feeds

Comunicado Tecnico, Empresa Brasileira de Pesquisa Agropecuaria (34): 4
Chemical composition and availability of nutrients in ingredients for poultry feeds
To assist in precise formulation of balanced and economical feed mixtures for poultry, chemical composition, contents of crude and metabolizable energy and of individual amino acids and also available tryptophan, were tabulated, on the basis of laboratory analysis and biological trials, for home-produced groundnut meal, whole or defatted rice meal, meat-and-bone meal from pigs, citrus pulp, barley with or without husks, maize gluten meal with 23 or 60% crude protein, crushed maize, combined feather and hydrolysed offal meal, incubator waste meal, soya bean meal and wheat bran. Results differed from those obtained in other regions and, especially, countries. Variations were greatest for items of animal origin.
