Prevalence of ovine and caprine fasciolasis in and around Assela town of Oromia Regional State, Ethiopia

Abstract

Coprological and postmortem examinations were made on 903 and 180 animals respectively to assess the prevalence of ovine and Caprine fasciolasis in Assela and its surroundings. Out of 657 sheep and 246 goats examined coprologically, 32.9% and 15.9% respectively were found to be fasciolasis positive in sheep and goats . On the other hand of the 110 sheep and 70 goats examined by postmortem examination, 31.8% and 7.1% respectively were found fasciolasis positive respectively. The study revealed significant variation in the prevalence of the disease between species (χ2 cal = 25.54,
d.f = 1, P < 0.001) and between study areas (χ2 cal =60.37, d.f = 2, P < 0.001) commonly for both species, and it showed significant variation between the months the study covered (χ2 cal = 37.3, d.f = 3, P < 0.001) and among the age groups considered (χ2 cal= 13.53, df = 1, P < 0.01) in ovine species.
