This experiment was conducted to determine the dietary threonine requirements for Nile tilapia. The fishes (37.61 ± 1.16 of initial weight) were allotted to a completely randomized design with four treatments, three replicates and 25 fishes per experimental unit. It was used a reference diet with 27% of CP and 3,000 kcal of DE/kg, supplemented with L-threonine, resulting in diets with 0.92, 1.06, 1.21, and 1.35% of total threonine. Synthetic amino acids were added to mantain their profile according to […]
