Hence knowledge of brucellosis occurrence in traditional livestock husbandry practice has considerable importance in reducing the economic and public health impacts of the disease. Methods A total of 1623 cattle sera were serially tested using the rose Bengal test as screening and complement fixation test as confirmatory tests. The Stata survey command was used to establish prevalences for the overall and individual variables while potential risk factors for seropositivity were analyzed using a multivariable logistic regression analysis. Results The results showed that 95 CI of the animals and 95 CI of the herds tested had antibodies against Brucella species. Village level seroprevalence ranged from 0 to 100 . A higher seroprevalence was observed in pastoral system than mixed farming although this variable was not significant in the final model. The final logistic regression model identified herd size with large odd ratio OR 95 CI and medium herds OR 95 CI showing higher risk of Brucella infection when compared to small herds. Similarly the odds of Brucella infection was higher in cattle aged above 4 years when compared to age groups of 1-2 OR and 3-4 years OR 95 CI . Herd level analysis of the risk factors revealed that large and medium herds as well as herds kept with multiple livestock species .
