ABSTRACT
The purpose of this study was to assess the prevalence of parasitic diseases in domestic hens that acquired from the poultry market between March 2023 and October 2023. In order to analyze blood parameters (Hb, PCV, RBC, and WBC), sixty mature chickens were employed. Blood samples (1 ml) were taken from each chicken’s jugular vein and placed into an ethylene diamine tetraacetic acid test tube. The tube was then gently shaken. The results were obtained using the Cell-Dyn Ruby equipment. The dissected intestinal portions of the sacrificed chickens were extracted in order to look at the pathological alterations, and the chickens’ intestines were checked for the presence of parasites. The findings showed that the overall rate of helminthes infection was 86.67%, with Cestoda accounting for 84.62% and Nematoda for 36.54% of cases (many of which had mixed infections). Five species of cestodes were recorded included: Raillietina echinobothrida (71.15%), Raillietina tetragona (38.46), Raillietina cesticillus (13.46%), Choanotaenia infundibulum (17.31%), and Hymenolepis sp (53.85%). There were three type of nematode: Ascardia galli (28.85%), Heterakis gallinarum (21.15%), and Epomidiostomum (7.69%). Our results showed that there is significant decreasing in the concentration of Hb, PCV, and RBC (P values= 0.021, 0.009, 0.034) respectively of chickens infected with helminthes compared to the control group. While the WBC was noticed with increased significantly (P value= 0.045) in the infected chickens. Histological examination of the chickens’ intestinal sections showed heterophilic infiltration together with villi and mucosal gland loss and degradation.
