Abstract

The present work aimed to evaluate the effect of metionine dietary levels on performance and chemical composition from Nile tilapia, during sex reversal phase. A 35 liter-aquarium with 15 animals was considered as an experimental unit. The treatments had been constituted by larvae feeding with diets containing 0.56; 0.65; 0.75; 0.85; 0.95% of total metionine. The animals were fed on ad libitum regimen. In the end of the experimental period, the performance parameters of length and weight, daily weigh gain, factor condition and survival were evaluated. The carcass chemical characteristics from animals as moisture, mineral matter, crude protein and eter extract were also evaluated. The data were submitted to the variance analysis (α=0,05). No difference (P >0.05) among treatments was observed. Results show that in rations for Nile tilapia, in this phase, the use of synthetic metionine affected neither the performance nor chemical composition of the animals
