Journal Title: Journal of Animal Production Advances - Year 2013, Vol 3, Issue 6
Abstract
A cross-sectional study was conducted in Menz Gera Midr Woreda from October, 2010 up to December, 2010 with the objective of determining the prevalence of ovine fascioliasis and to identify the effect of putative risk factors on the intensity and rate of ovine facioliasis infection. The study method involved was collection of a faecal samples and corpological examination using standard sedimentation technique and questionnaire survey. A total of 384 sheep were sampled from the study area. The sampling method has involved all age group, sex and four ago-ecological zones. During sample collection information concerning history of deworming, observation of bottle jaw,ascites and husbandry system were gathered on the livestock owners. Based on this study the overall prevalence of ovine fascioliasis was found to be 40.9%, and a total of 40 sheep owners were interviewed and 95% (n=38) have observed bottle jaw (locally it is recognized as Kuakult, Mawulie) on their flock and 25% (n=10) respondents have encountered ascites on postmortem. Among the respondents 87.5% (n=35) deworm their flock twice a year and 5% (n=2) deworm their sheep when showing bottle jaw. From this study the result of stastical analysis of various factors with risk of ovine fascioliasis indicated that there was no significant difference between Sex (x2= 3.59, p=3.84), Ag e (x2=1.9, p=3.84), and Agro-ecology (x2=2.38, p=7.84). However the prevalence of ovine fascioliasis was relatively higher in older individuals(greater than one year),female individuals and in frost or wurch agro-ecological zones than individuals with less than one year age, male individuals and the rest agro-ecological zones respectively. Then in conclusion the overall prevalence of ovine fascioliasis indicated that it was the major factors for the reduction of livestock product and productivity of the study area and strategic deworming of the flock is better to prevent the disease.
