Three hundred and ninety six reverted Nile tilapia (Oreochromis niloticus), from Thailand strain, averaging initial weight of 0.86 ± 0.02 g were used to evaluate the effect of feeding methionine plus cystine:lysine levels, based on the ideal protein concept, with deficient levels of digestible lysine (1.40%). The experiment was analyzed as a completely randomized design, with six treatments, six replications by treatment and 11 fishes for experimental unit. The treatments consisted of five diets with different ratios of digestible methionine […]
