Abstract | |||||
| The present study shows that the overall prevalence of gastro-intestinal nematodes in sheep was 58.18% in Mymensingh. Sheep were infested with Strongyloides spp. (7.7%), Haemonchus spp. (18.18%), Trichuris spp. (5.45%), Oesophagostomum spp. (9.09%) and mixed infection (14.18%). Twenty sheep were selected from fifty five sheep for this study which was heavily infected with gastro-intestinal nematodes marked by McMaster method. Sheep were treated with Vermic® (ivermectin) @ 0.23 mg kg-1 body weight. A significant (p<0.01) reduction of EPG count was found on 7th, 14th, 21st and 28th day of Vermic® (90.51, 89.85, 87.91 and 86.38%) treated sheep. The EPG count of untreated control group were significantly (p<0.01) increased about 7.88, 11.45, 20.15 and 30.26% on 7th, 14th, 21st and 28th day, respectively. After treatment with Vermic®, Total Erythrocyte Count (TEC), Hemoglobin (Hb) content and Packed Cell Volume (PCV) were increased significantly (p<0.01 and p<0.05) in sheep. On the other hand Total Leukocyte Count (TLC) was decreased significantly (p<0.01 and p<0.05) in all treated sheep. The body weight was increased significantly (p<0.01 and p<0.05) in Vermic® treated group. On the other hand body weight was decreased in untreated control group. Vermic® may be used as a broad spectrum anthelmintic against gastro-intestinal nematodiasis in sheep. | |||||
