Abstract

This study was performed to investigate the effect of Coccidia infestation on several biochemical parameters in laying hens. One hundred and twenty laying hens were assigned into two groups; the first one contained 20 chickens and kept as control group. The second group includes 100 chickens infested with Coccidia. Blood samples were collected by slaughtering of the birds. The obtained results revealed that, significant decreases in serum glucose, total protein, albumin, globulin, (A/G) ratio, total cholesterol, triglyceride, HDL, LDL, VLDL, SOD, iron, calcium and inorganic phosphorus in Coccidia infested hens as compared with control group. Furthermore ALT, AST, alkaline phosphatase, MDA and CAT were significantly increased in Coccidia infested hens on comparison with control group. From the obtained results it could be concluded that Coccidia infestation affecting laying hens caused a marked biochemical changes of some investigated blood parameters.
