Abstract
The objective of this study was to evaluate the effects of the inclusion of extruded soybean in diets for piavucu ( 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 piavucu 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. KEYWORDS: alternative feedstuff; digestible energy; fish production; Glycine max L; nutrition.

Summary
EFEITO DA INCLUSÃO DE SOJA INTEGRAL EM RAÇÕES EXTRUSADAS NO DESEMPENHO DE JUVENIS DE PIAVUÇU (Leporinus macrocephalus L.). Com este estudo objetivou-se avaliar o efeito da inclusão de soja integral em rações extrusadas com diferentes níveis de energia digestível na dieta de juvenis de piavuçu (Leporinus macrocephalus L.). Foram distribuídos 100 peixes com peso inicial de 5,06 ± 0,41 g, em 20 aquários (80 L), num delineamento inteiramente casualizado com cinco tratamentos (0; 20,0; 35,0; 50,0 e 67,5% de soja integral nas dietas) e quatro repetições. Isocálcicas, isofosfóricas, isoaminoácidicas para metionina e com diferentes valores de energia digestível (3.193; 3.326; 3.413; 3.510 e 3.621 kcal/kg) foram fornecidas aos peixes durante setenta dias. Concluiu-se que a inclusão de soja integral nas rações para juvenis de piavuçu é viável, podendo substituir parcial ou totalmente o farelo de soja, sem prejuízo de desempenho, embora proporcione maior deposição de gordura na carcaça.
