Resumo

The objective of this study was to evaluate the effects of the inclusion of extruded soybean in diets for piavuçu (Leporinus macrocephalus L.) juveniles with different levels of digestible energy. A hundred fish with initial weight of 5.06 ± 0.61 g were distributed into 20 aquarium (80 L), in a entirely randomized design with five treatments (0.00, 20.00, 35.00, 50.00 and 67.5% full fat soybean in the diets) and four replications. Isonitrogenous, isocalcium, isophosphorus, isoaminoacids for methionine diets with different digestible energy values (3,193; 3,326; 3,413; 3,510 and 3,621 kcal/kg) were given to fish for seventy days. The criteria evaluated were weight gain, length increment, daily feed intake, feed gain, protein efficiency ratio and survival rate. No differences (P>0.05) were observed among treatments regarding the performance criteria. We concluded that the inclusion of full fat soybean in piavuçu juveniles diet is a viable option, and it may partially or totally replace soybean meal, without decreasing performance, while providing greater deposition of fat in the carcass.
