Prevalence of Three Liver Parasites in Sheep and Goats in Al-Madinah Al-Munawwarah , Saudi Arabia Kingdom

Abstract

The epidemiological status of cysticercosis, hydatidosis and dicrocoelosis in sheep and the production practices of sheep farmers that increase the risk of exposure of sheep to their infectious agents were studied in Al-Madinah, during 2011-2012. A total of 450 sheep and 1650 goats were inspected randomly at an abattoir survey and the prevalence of hydatidosis, cysticercosis and dicrocoelosis was recorded as 0.4%, 13.3% & 0.6% in sheep and 0.16%, 1.8% & 0.0% in goats respectively. The prevalence of cysticercosis increased dramatically in days of wedding parties to more than 75% because a large number of sheep was brought from one grazing endemic farm. The improper disposal of dead animals, the access of farm dogs to offal of slaughtered sheep, the farmers carelessness to treat their dogs with anthelmintic, and the grazing of flocks in fields where stray dogs have free access; increased the sheep and goats risk of exposure to hydatidosis and cysticercosis.
