摘要: Two experiments were carried out in order to estimate the requirements of digestible valine and isoleucine for growing meat quails. In experiment 1, 2160 quails with 1 day age, not sexed, used, distributed a completely randomized design 4x4 factorial arrangement, four levels (0.90, 1.10, 1.30, 1.50%) (0.80, 1.00, 1.20, 1.40 %), totaling 16 treatments three replications 45 per experimental unit. The body weight, weight gain, accumulated biomass linearly increased function influenced quadratic way estimating 1.38% isoleucine. 2, 1440 quails, (0.82, 1.02, 1.22, 1.42%) (0.73, 0.93, 1.13, 1.33%), 30 performance from 15 35 days age was affected by diets. It concluded that maximum quail one 14 1.50% 1.38%, respectively, corresponding relations: valine: lysine 95% isoleucine: 88%. lower evaluated, period old, 0.82% 0.73% isoleucine, relations 52% 46% sufficient meet nutritional without compromising performance.
