This experiment was carried out in of Fish Nutrition laboratory of the Departament of Animal Improvement and Nutrition (FMVZ), Unesp - Campus of Botucatu, State of São Paulo, Brazil). The study investigated the effect of raw full-fat soybean meal feeding on fingerlings Nile Tilapia (Oreochromis niloticus). The suitable level of consumption of raw full-fat soybean meal (RSF) was determined taking into account anatomopathological analyses. Each isoproteic (26% CP) and isoenergetic (3.000 kcal ME/ kg) diet contained raw full-fat soybean meal at 6.0%, 12.0% and 18.0% repectivily. Anther treatment without soybean meal was used as control. Forty-eight fingerlings with similar size and lenght (mean Wt ± SD: 6.47 ± 0.64g; and mean Lt ± SD: 54.94 ± 7.79 mm) were used at the beginning of the experiments. The treatments with 12.0 and 18.0% RSF induced a higher granulation level in the pancreatic cells and an increased vacuolition of the hepatocytes. This made evident a deleterious effect of the raw full-fat soybean meal at these considered levels (12.0% and 18.0% RSF).Downloads
