Abstract | ||||
Part II is a continuation of the previous study (part I) using the same experimental groups. It was carried out to investigate the effect of phytase and citric acid (CA) either alone or in combination on some blood traits and organ morphology in male broiler chicks from 8-40 days of age. The results revealed that all supplemented groups did not show any significant changes in hematological parameters. CA did not result in any significant changes in all measured blood biochemical parameters. Phytase did not induce any significant changes in AST activity, total cholesterol, HDL, triglycerides, urea, creatinine and glucose concentrations, while it increased ALT activity both in the overall mean and during most of the sampling periods. Supplementation of broilers feeds with mixed additives produced a significant increase in AST activity at 40 days of age, while total cholesterol concentration was significantly decreased. Triglycerides level was significantly increased at 24 days of age. Total protein level was significantly increased than phytase and CA supplemented groups at 24 days of age and then control group at 32 days of age. Blood glucose level was significantly increased at 24 days of age vs all experimental groups and at 32 days of age vs control and phytase supplemented groups. Histopathological examination revealed that the liver of chicks supplemented with phytase showed mild vacuolization in the cytoplasm of hepatocytes. The spleen showed lymphoid hyperplasia in white pulb of all supplemented groups, and the pancreas showed activation and proliferation in islets of Langerhans. | ||||
