Small Intestinal Helminth Parasites in Slaughtered Sheep and Goats in Hawassa, Southern Ethiopia
نویسنده
چکیده
This study was carried out from November 2007 to March 2008 to identify the species and to determine the burden of small intestinal helminth parasites of sheep and goats slaughtered in Hawassa, southern Ethiopia. Intestines of 116 sheep and 71 goats were examined using standard procedures. Three species of parasites namely Trichostrongylus colubriformis, Bunostomum trigonocephalum and Moniezia expansa were found infecting intestines of both sheep and goats. The overall prevalence of nematodes was 93.1% and 91.5 % in sheep and goats respectively. Moniezia expansa was identified in 69.0% sheep and 55.0 % goats. The prevalence of T. colubriformis and B. trigonocephalum in sheep and goats were 83.6% and 77.5% and 50.8% and 38.0% respectively. There was no statistically significant difference in the prevalence of the parasitic worms between the two species of animals (P >0.05). The mean adult worm counts of T. colubriformis, B. trigonocephalum and scolices of M. expansa in sheep were 641, 25.1 and 42.6 respectively, while they were 543.8, 19.7 and 33.9 in goats. There was no significant difference in worm burden among the same species of parasites between sheep and goats (P >0.05). The study animals, in general, had light to moderate worm burden. The study indicated a high prevalence of intestinal nematodes and cestodes in sheep and goats slaughtered in Hawassa with light to moderate degree of infection.
