FILIPETTO, Jorge Eugenio da Silva et al. Replacement of bovine liver by corn gluten, wheat gluten and soybean meal in rations for piava (Leporinus obtusidens) post-larvae. Cienc. Rural [online]. 2005, vol.35, n.1, pp.192-197. ISSN 0103-8478.

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.

Keywords : piava; post-larvae; wheat gluten; protein sources; corn gluten; soybean meal.
