Resumo
This study aimed to test the effect of the ingestion of tryptophan on the self-balancing of the portion and the productive performance of Nile tilapia in the juvenile and adult stages. For this purpose, tryptophan supplemented diets were prepared as follows: RC (3,2g amino acid kg-1, control), R2 -6,40g kg-1, R4 -12,80g kg-1, R6 -19,60g kg-1 and R8 -25,60g kg-1, offering two portions for the selfbalancing tests. The results showed that Nile Tilapia self-balanced daily consumption of tryptophan, improving feed intake, weight gain, standard length and feed conversion. The results indicated that juvenile and adult Nile Tilapia is capable of regulating the amino acid consumption at 8,40g kg-1 and 8,20g kg-1 of the diet, respectively.
