          Abstract

          Este trabalho foi realizado em duas etapas, com o objetivo de avaliar o efeito dos glutens de milho e trigo, e do farelo de soja, em substituição ao fígado bovino no crescimento de pós-larvas de piava (Leporinus obtusidens). Na primeira etapa, foram elaboradas rações com glúten de trigo ou milho, em substituição ao fígado bovino nos níveis de 25, 50 e 100%. O glúten de trigo foi mais eficiente que o de milho como substituto do fígado bovino, sendo que até 40% de substituição proporciona maior tamanho e sobrevivência das pós-larvas. Na segunda etapa, foi avaliada a substituição dos 40% de glúten de trigo por farelo de soja, em níveis crescentes de 25, 50, 75 e 100%. A substituição do glúten de trigo por farelo de soja em até 75%, apresenta os melhores índices para pós-larvas de piava, aos 21 dias de idade.

          Translated abstract

          The objective of the study was to evaluate the corn and wheat glutens and soybean meal in partial replacement to the bovine liver in granulated rations for rearing of piava post-larvae. In the first experiment meals were elaborated with wheat and corn glutens in substitution to the bovine liver in the levels of 25, 50 and 100%. The wheat gluten was more efficient as substitute of the bovine liver, and up to 40% of replacement showed the highest fish size and survival. In the second experiment, the replacement of the wheat gluten by soybean meal in growing levels of 25, 50, 75 and 100% of the 40% of inclusion of the wheat gluten obtained in the first experiment was evaluated. The substitution of the wheat gluten by soybean meal up to 75% provides the highest size for piava post-larvae, at the 21 days of age.
