Five hundred and forty 7-days old female quails, averaging 21.50 g, were used during 35 days. A completely randomized blocks design with five replicates and 18 females per experimental unity was used to study the effect of six digestible methionine plus cystine: digestible lysine ratios (0.48, 0.53, 0.58, 0.63, 0.68 and 0.75) on the traits evaluated during the growing period. Final weight (g), weight gain (g), feed intake (g), feed conversion (g/g), feather rate (%), chemical composition (%) (dry matter, […]
