It was determined,in this work, the nutritional value of four energetic feeds (corn meal, sorghum,whole rice bran, and ground rice) for surubim juveniles. Apparent digestibilitycoefficients of dry matter (DM), crude protein (CP), and gross energy (GE) wereevaluated by food replacement methodology in a reference-feeding using 0.1%of chromic oxide as an external marker. It was used 240 fingerlings with anaverage weight of 30 g distributed in tanks fitted for faeces collection. Acomplete random design with four diets, each one with four replicates, was used.Apparent digestibility coefficient of dry matter for corn meal was 62.3%; forrice bran, 59.7%; for ground rice, 40.4%, and for sorghum, 38%. Digestibilitycoefficients for crude protein were, in this order, the following: 87.4, 83.8,85.3 and 81.1% and digestibility coefficient for gross energy were: 62.4, 66.4,46.9 and 47.8%. Among the evaluated feeds, the one with the highest digestibilityof dry matter, crude protein, and gross energy is the rice bran and the onewith the lowest digestibility is the sorghum.
