Abstract

Aiming to evaluate spray-dried yeast on the performance of reverted Nile tilapia fingerlings, 175 fingerlings, with 0.72 ± 0.18 g, distributed in complete randomized design with 5 treatments and 5 replicates, in a 50 L aquarium with 7 fingerlings, were used as the experimental unit. The consumption used 100 fingerlings, with 7.2 ± 0.84g, distributed in complete equal design with 4 replicates in an aquarium with 5 fries, was the experimental unit. Isoprotein and isoenergetics with growing levels of yeast (0.0%, 1.5%, 3.0% 4.5% and 6.0%) diets was used. A linear growth (P < 0.05) was observed for means of final weight, final length, protein efficiency rate. A linear decrease (P < 0.05) was observed for conversion rate and food intake showed no statistic difference (P > 0.05). The best performance of reverted Nile tilapia fingerlings was provided by diet with 6.0% yeast ration level
