The effects of the digestible lysine level were assessed in feeds for Nile tilapia fingerlings (Oreochromis niloticus), based on the ideal protein concept. Four hundred and thirty two reverted fingerlings were used, average weight 1.12 ± 0.02 g, in a randomized complete design, consisting of 6 feeds, six replications and twelve fish per experimental unit. The diets consisted of a basal diet with 29.12% crude protein and 3,000 kcal/kg digestible energy, supplemented with synthetic amino acids, resulting in six diets […]
