A Cross Sectional Study on the Coprological Prevalence of Ovine Fasciolosis in Amhara Sayint District, Ethiopia - Abstract
A cross-sectional study was conducted to determine the prevalence of fasciolosis in local breeds of sheep in Amhara Sayint district from November 2016 to April 2017. Fecal samples from 383 sheep, 164 from males and 219 from females, were collected and examined by standard sedimentation technique. The overall prevalence rate of fasciolosis was found to be 41.3%. The prevalence was compared among different risk factors. Additionally, month specific prevalence was recorded for comparison. The highest prevalence was recorded on November and March being 58.4 and 61.2 respectively. There was no statistical difference (p>0.05) between sexes of animals. However, there was a statistically significant difference (p<0.05) according to age, body condition, origin and the history of deworming. The results revealed that the infection was significantly higher in adult animals than in the young ones. The infection rate in poor body conditioned animals was highest and lowest in good body conditioned
animals. Animals originated from high land were most affected by the infection than those from low land. In a similar way, dewormed animals were found to be less challenged by the infection than the non-dewormed ones. The present investigation indicated that fasciolosis is a prevalent disease of sheep in the study area. Hence, it demands further studies on its economic significance. Fasciolosis is the important disease in the study area. Therefore, strategic and tactical control measures need to be implemented.
