This work evaluated the effect of different milling degree of feeds on Nile tilapia performance during sex reversal period. A completely randomized design with four treatments and six replicates was utilized. The treatments were the milling degree of feed by 0.25, 0.50, 0.70, and 1.00 mm screen. The diets used fulfilled larvae necessity. Data of weight (W), length (L), daily gain weight (DGW), factor condition (FC) and survival (S) were evaluated. Data were submitted to ANOVA and regression analysis in case of significant difference were detected (P = 0.05). Only W, DGW and FC presented significant difference between treatments, showing a quadratic effect (P < 0.05) and better results to 0.60, 0.60 and 0.63 mm of feed milling degree, respectively. Diet with milling degree of 0.60 mm screen was recommended to Nile tilapia reversion phase
