Seroprevalence Study Of Bovine Brucellosis In Extensive Management System In Selected Sites Of Jimma Zone, Westernethiopia

摘要

The prevalence of bovine brucellosis was measured in cross sectional study in Jimma zone, Western Ethiopia using Rose Bengal Plate Test (RBT) and CFT from October 2003 to April 2004. The study animals consisted of 1305 local breed found in extensive system in five districts of in the zone. The overall individual animal prevalence and herd prevalence of 0.77% and 2.9% were recorded in five districts, respectively. Higher prevalences were observed in larger herd size (P< 0.001); older age groups were affected more than younger animals (P<0.05) in the extensive management system. No reactions were observed in male. Seropositivities of 8% were observed in animals with previous history of abortion. The study demonstrates that the prevalence of brucellosis in the area is low; however, there is probable risk of spread of the disease in the unaffected cattle population since there are no precaution measures taken in the areas that should have been practiced by farmers. Since the prevalence is below 2%, test and slaughter with compensation payment to farmers is recommendable.
