Abstract: Cross-sectional study of nematode parasites of sheep and goats was conducted from November 2008 to May 2009 in Hawassa with an attempt to determine the prevalence rate and worm burden of abomasal and small intestinal nematode of sheep and goats. A total of 180 post mortem examination (112 sheep and 68 goats) slaughtered in different restaurants in Hawassa town were examined. Five species of nematode were identified in both animal species with the overall prevalence rate of 72.3 and 36.8% of small intestinal nematodes in sheep and goats, respectively and 82.1 and 61.8% of abomasal nematode in sheep and goats, respectively. The specific prevalence rates observed for nematode were 75.9, 4.5 and 29.4% in sheep and 55.9, 2.9 and 26.4% in goats of Haemonchus contortous, Trichostrongylus axie and Ostertagia (Teladorsagia) circumcinecta, respectively and 63.4 and 29.4% of T. Columbriformis in sheep and goats, respectively and 47.3 and 23.5% of Bunostomum trigonocephalum in sheep and goats, respectively. There was statistically significant difference (p<0.05) in the prevalence rate of the parasite with age and species of animals while Trichostrongylus axie has no significant difference (p>0.05). The present study showed that nematode of sheep and goats are the most prevalent problem in the study area affecting the health of those animals and appropriate control measure should be instituted.
