Prevalence and economic importance of liver parasites: Hydatid Cyst, Fasciola species and Cysticercus tenuicolis in sheep and goats slaughtered at Addis Ababa abattoir enterprise in Ethiopia

摘要

This research was designed to determine the prevalence of?Cysticercus tenuicollis,Fasciola?and Hydatid cyst and to estimate the magnitude of the direct financial losses attributed to the condemned liver of sheep and goats slaughtered in the abattoir. Ante-mortem examination was done to determine the origin and age of animals slaughtered. Post-mortem inspection was conducted on a total of 1152 animals comprising 576 sheep and 576 goats and (288/1152) 25% livers were?condemned due to parasitic induced gross lesions. From 176 (30.6%) positive sheep, 45 (7.81%) were infected by C.tenuicollis, 108 (18.75%) by?Fasciola?and 23 (3.99%) by Hydatid cyst. Similarly from 112 positive goats, 91 (15.8%), 13 (2.26%) and 8 (1.39%)? C.?tenuicollis,?Fasciola?and Hydatid cyst were recorded.?Fasciola?was leading cause of liver condemnation in sheep and?C. tenuicollis?in goats. Hydatid cyst was responsible for lowest condemnation rate. A statistically significant difference was observed between species and origin of small ruminants for?Fasciola, C.?tenuicollis?and Hydatid cyst with P < 0.05. The abattoir’s financial losses due to condemnation of liver by parasitic induced gross lesions accounts approximately 157,684 ETB annually.
