| Abstract | ||
| The present study was undertaken to investigate the effect of adding the Robenidine (Rop), as an anticoccidian and Tetracyclines (Tcs), as an antibiotic on certain blood traits and liver tissue of broiler chickens. A total of 180 chicks (Rose strain) were included in the study, chicks were divided into:- 1- Control group, the chickens are given water and fodders free from additional. 2- (Rop) group, the chickens were given water free from antibiotic and fodders containing on anti coccidian. 3- (Tcs+Rob) group, the chickens were given water containing antibiotic and fodders containing of anti coccidian. The chickens were given antibiotic Tetracyclines in a drug of 500 mg/0.5kg from the body weight. While, the anticoccidian Robenidine was added at the level of 0.5 kg for each Ton of fodder. The samples of the chickens were taken during four age periods 20, 35, 41, 48 days after hatching. The result showed a significant increase ( p≤ 0.05) in the (Tcs+Rob) group as regards weight of the chickens at 48 days, while it recorded a significant decrease (p≤ 0.05) in the second treated (Rop) group in the weight of the chickens in comparing with the control group. From the results of blood pictures, there was a significant increase in the percentage of Heterophils in both groups associated with significant decrease in the percentage of lymphocyte in both groups of 35, 41, 48 days when compared to the control groups. Other types of white blood cells did not exhibited any significant differences between the treated groups. The results of biochemical tests for the blood serum reveled no significant differences in activity of AST and ALT enzyme, while there appeared a significant increase (p≤ 0.05) in the total cholesterol level at the age of 48 days. From the tissue exam for the samples of the liver, Histopathological changes were noticed in the liver about the blood congestion and appearing inflammable tissue congestion was severe in (Tcs+Rob) group at the age of 41 days, while the inflammable tissue appeared in bigger size in (Rop0.) group at the same age. It could be concluded from the present study, the side effects of Robenidine and Tetracyclines in liver and blood tissues. | ||
