This research aimed to evaluate spray dried alcohol yeast (Saccharomyces cerevisiae) and zinc (zinc oxide) as pronutrient in initial diet for Nile tilapia (Oreochromis niloticus L.). The experimental diets, isoproteic (30.00%DP) isoenergetic (3200kcal DE/kg diet), were supplemented with three levels (0.50, 1.00 2.00%) (150, 300 600mg/kg). An additional no was used. experiment a factorial 3 x (yeast zinc) plus an treatment (control) four replications completely randomized block design. Weight gain, apparent feed conversion, specific growth rate, protein efficiency digestibility coefficients dry matter, crude protein, total lipid gross energy of diets analyzed. acted fingerlings the 1.00% 300mg Zn/kg diet, presented better responses on performance coefficient. There positive interaction between weight conversion coefficient energy.
