Resumo: | The modernization of poultry laying hens resulted in birds more productive with lower body weight, lower feed intake and higher production efficiency. This modernization resulted in the need for feeding programs increasingly modern and efficient metabolically, especially for amino acids, meeting the demand biological maintenance, gain and production of the birds. In this context, knowledge of the forms of amino acids supplementation in the diet, on the basis total or digestible, is fundamental because of its participation in the formation of pullet and in the production and quality of eggs of hens and reduction in production costs. Diets based on digestible amino acids can provide productive and economic maximization and reduction in nitrogen excretion by birds. Methods for determining the digestibility of amino acids in foods can be: in vitro, indirect and direct, the latter being the most widely used scientifically.
