Identification of gastrointestinal endoparasites in sheep (Ovis sp.) at various ages in Arjuna Farm, North Sumatra

Gastrointestinal endoparasite is an infection that causes a decrease in the productivity level of sheep so that it detriments to the farmers. The purpose of this study was to compare the type, the prevalence and the intensity of endoparasites in each age group. Samples were taken as many as 7 fresh feces from each group of lamb, virgin, and adult from a total of 21 sheeps. Fecal samples were examined and prepared using the E.P.M Mc Master Protocol while endoparasites were identified under microscopical examination. The results showed 5 species of gastrointestinal endoparasites, i.e Eimeria sp., Dicrocoelium sp., Haemonchus sp., Strongyloides sp., and Capillaria sp. Eimeria sp. showed a prevalence of 85.7% in commonly category and intensity of 2216.6 or super infection category. Haemonchus sp. had a prevalence of 85% (common), an intensity of 671.4 (very severe), and the Strongyloides sp. had a prevalence of 85% (common) and an intensity of 200 (very severe). The lambs were found to be infected by Eimeria sp. with a prevalence of 100% (common) and an intensity of 2871.4 (super infection). Haemonchus sp. had a prevalence of 100% (common) and an intensity of 1200 (super infection), Strongyloides sp. had a prevalence of 71% (usual) and an intensity of 860 (very severe) and the Dicrocoelium sp. had a prevalence of 14% (often) and an intensity of 400 (very severe). The adult sheeps were found to had Eimeria sp. with a prevalence of 100% (common) and an intensity of 371.4 (very severe). The Haemonchus sp. had a prevalence of 14% (often) and an intensity of 200 (very severe). Strongyloides sp. had a prevalence of 57% (frequent) and an intensity of 200 (very severe) and the Capillaria sp. had a prevalence of 14% (often) and an intensity of 100 (severe). The prevalence and intensity of endoparasites in sheeps at Arjuna Farm was classified as very high.
