Study on the Prevalence of Ovine Fasciolosis in Wadla Woreda, North Wollo, Ethiopia

A cross - sectional study on the prevalence of ovine fasciolosis was conducted in Wadla district from October 2016 to June 2017. A total of 384 fecal samples were randomly collected directly from the rectum of individual animals. Parasitological investigation was performed using sedimentation technique. From a total of 384 copro - logical ly examined samples 130 sheep were found positive for fasciolosis with an overall prevalence of 33.85%. From the study peasant association Kone, Dorera, Betehar, Beteyohannis and Gashena were accounted for 34.61%, 32.47%, 32.89%, 35.06% and 34.21 % respect ively. The difference in the prevalence in the five peasant associations was not statistically significant (p> 0.05). The prevalence of ovine fasciolosis was computed for the different age, sex and body condition categories. The prevalence rate of fasciolo sis in young sheep 32.43% was less than 34.75% and the difference were not statistically significant (p>0.05). The prevalence of fasciolosis in sex groups in the present study was 34.69%, 32.98% in female and male respectively. On the other hand in the pre sent study area the prevalence of fasciolosis was found to be higher in sheep with poor body condition than those with medium and good body conditions with prevalence of 36.5%, 33.88% and 27.03% respectively. There is no statistically difference (p>0.05) b etween three types of body condition scores. It was concluded that ovine fasciolosis was prevalent, thus causing major economic lass in the study area. Hence, control strategies targeted on the parasite and the intermediate hosts as well as implementation of appropriate grazing management in the study area are warranted.
