The aim of this study was determine the apparent digestibility coefficient (ADC) of dry matter (ADC(DM)), gross energy (ADC(GE)), crude protein (ADC(CP)), amino acids (ADC(AA)), and phosphorus (ADC(P)) of the corn, rice bran and wheat bran subjected to extrusion process for Nile tilapia (Oreochromis niloticus) juveniles (101.6 +/- 3.1 g). A reference diet (RD) was formulated based on soybean meal as protein source. Then, test diets were obtained by replacing 30% of the RD with the ingredients tested. Chromic oxide was used as inert marker (0.1%). Feces collection was performed by sedimentation tanks with conical bottom (300 L). The ADC(CP) and ADC(AA) were 66.71 and 69.9%, 59.71 and 66.08%, and 67.89 and 76.63% for corn, rice bran and wheat bran, respectively. Corn was considered the best energetic feed to Nile tilapia, for presenting the highest values of ADC(DM) (98.42%), ADC(GE) (93.49%) and ADC(P) (67.16%).
