Abstract

Study was conducted to assess the prevalence and economic loss associated to Fasciolosis in small ruminants slaughtered at Modjo Modern Export Abattoir (MMEA) Modjo in East Shawa, Oromia regional State, central Ethiopia. A total of 1000 animals (500 sheep and 500 goats; 250 animals each from 4 origins) were examined for the presence of Fasciola sp. Species, age and origin of animals was taken in to consideration. Liver incision, observation and species identification on the basis of size and morphology of adult worm were applied. An overall prevalence of 3.2% was registered. The prevalence was 5.6 and 0.8% sheep and goats, respectively. It was 1.25% in young and 4.5% in adult by age groups. The prevalence of 7.6, 0.8, 2.4 and 2.0% was observed in animals from Arsi, Borana, Jinka and Yabello in respective origin. Significant difference (P<0.05) was observed in occurrences of Fasciolabetween animals species and age as well as among origin of the animals. The prevalence of 1.9% Fasciola hepatica and 1.6% Fasciola gigantica was identified from positive cases. Significant difference (P<0.05) was observed in prevalence of F. hepatia in animal species, age and origin. Although insignificance difference (P>0.05) in F. gigantica among animal origin, significant difference (P<0.05) was observed between animal species and age groups. The current study also shows annual monitory loss of $3784.52 from liver condemnation as result of fasciolosis and other associated pathological and parasitological conditions. Therefore further studies on the epidemiology, seasonal dynamic of the disease, the snail intermediate host and impacts of the disease in animal production with implementations of fruitful intervention strategies in the animal origin areas necessary.
