Abstract

Soybean meal is an important source of protein in the diet of poultry bird. However, it has antinutritional factors which have to be taken care. Therefore, the study was carried out to determine the effect of replacement of solvent extracted soybean meal (SBM) with expeller extracted soybean meal on pathology of various organs along with serum AST, ALT, Urea and Creatinine. The study was carried out on day-old broiler chicks (n=180), which were kept and randomly divided in to 5 groups (A, B, C, D and E). Birds of these groups were given treatment by replacing 0%, 25%, 50%, 75% and 100% of solvent extracted SBM with expeller extracted SBM, respectively. The trial lasted for 21 days. Birds were fed iso-nitrogenous and iso-caloric diets. All the birds from each group were slaughtered. The results indicate that the effect of expeller extracted soybean meal on kidney, liver and pancreas were severe in birds given 100% expeller extracted SBM. However, where 100% solvent extracted SBM was used the changes were less severe. While, the changes in intestine were more severe in birds given 100% solvent extracted SBM. The results on serum creatinine and urea supported histological changes seen in kidney in respective groups. However, the results of serum AST and ALT did not correspond well, as in liver, more severe changes of necrosis were noted in birds given 100% expeller extracted SBM, while the values of these enzymes were the lowest. It is concluded from the present study that birds kept on 100% expeller extracted and solvent extracted soybean meal showed effect on various body organs, while 50% of both the solvent extracted and expeller extracted soybean meal in combination gave better results
