| dc.description.abstract | The current study was conducted to determine the prevalence of Gastro-intestinal nematodes of indigenous Bonga sheep breed in three sellected districts of Kafa and Bench maji zones of Southern Region from September 20 I 0 to April 2011. Cross sectional study fo prevalence r detenrunation using post mortem and fecal examination and longitudinal prospective study for characterization of the partial seasonal dynamics of nematodes was carried out in this study. A total of 60 animals were subjected to post mortem examinations and 2304 fecal samples were analyzed using standard coprological techniques (flotation and modified McMaster fecal worm egg counts). Questionnaire survey was conducted in randomly selected 6 PA's and 60 households from three districts. Results from coprological examination revealed the overall prevalence of nematodes in Bonga sheep were 96.7%. During post mortem examination, four nematode species (Haemonchus contortus, 76.8%), (Oesophagostomum colombianum, 43.3%), (Bunostomum trigonocephalul1l, 30%) and (Trichostrongylus axei 25%), were identified. Fecal examination results in all study sites from population of Bonga sheep during the two sampling periods (early rainy and late dry seasones) indicated significant differences (p<0.05) in mean egg count per gram of feaces. About 90 % of Bonga sheep had EPG value 50-800 the remaining had 801-1200. Polyparasitism predominated in all study areas varying from 100% in Adiokaka, and 95% in North bench and 95% in Gimbo districts. Absence of veterinary services and lack of helminthes control strategies were believed to be responsible for such higher worm prevalence in the areas. These findings indicate that nematode parasites are a serious treat to the existing small ruminant population and livestock productivity at large in these study districts and require an immediate professional intervention | |
