CORREA, G.S.S. et al. Total methyonine + cystine requirement for meat type quails during the growing phase. Arq. Bras. Med. Vet. Zootec. [online]. 2006, vol.58, n.3, pp.414-420. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352006000300020.
Total methyonine + cystine requirements during the initial (7-21 days of age) and final period ( 22-42 days of age) of the growing phase were estimated for meat type quails in a completely randomized experimental design with six treatments, five replicates and 13 quails per experimental unit. Weight gain (g), body weight (g), feed consumption (g) and feed : weight gain ratio (g/g) were evaluated for quails fed on .73, .79, .85, .91, .97 and 1.03% methyonine + cystine diets. Meat type quails fed .95% and .73% methyonine + cystine diets during the initial (7-21days of age) and final period (22-42 days of age) of the growing phase show maximum weight gain.
