A cross sectional sero-prevalence study was carried out in Bokoji Town during March 2014 in order to determine the prevalence of bovine brucellosis. A standard questionnaire format was used to collect information relevant to the epidemiological investigation such as species, age and sex. The study subjects included 384 cross bred cattle reared under intensive management system. Blood samples were collected from animals above six months of age. The study animals were selected using simple random sampling method. A total of 411 blood samples were collected from jugular vein of each selected animal after proper restraining. The individual animals in the study were identified by their respective identification numbers or names. About 5-10 ml of blood was collected in plain vacutainer tubes. The blood samples will be allowed to clot at room temperature. Serum was separated from clotted blood by decanting to cryogenic vial and was kept in a deep freezer (-20 °C) till tested serologically using the Rose Bengal Plate Test. The collected sera were tested by (RBPT) Rose Bengal Plate agglutination Test in Asella Regional Veterinary Laboratory and the sero-prevalence of bovine brucellosis in these areas was found to be 0%. We appreciate the practices of the farms on the control of bovine brucellosis infection in this district. However, the following general sanitary measures are of some beneficial effect in preventing and controlling this disease for the future: Newly purchased animals must be isolated and tested for brucellosis before introducing them to the herd, contact during grazing with animals of unknown status must be avoided and Brucellosis test of all animals should be done at least once in a year.
