摘要: To establish the amino acid requirements for broilers, ideal ratio of lysine to acids is used. This criterion based on small variation in proportion with lysine. Few studies deal broiler breeders. A factorial method calculating requirement was proposed by Fisher et al. (1973) egg production and body weight maintenance, including standard deviation an economic factor. Based this method, objective study determine efficiency utilization methionine cystine (Met+Cys) threonine (Thr) their (Lys).
