The present work was conducted to investigate the prevalence of bovine brucellosis on the basis of serological test viz., MRT, RBPT, STAT, I-ELISA during the period from February, 2015 to May, 2016. The prevalence of brucellosis was recorded, 10.53%, 12.69%, 13.08% and 13.84% in bovine by MRT, RBPT, STAT and I-ELISA respectively. Sex-wise higher prevalence rate was recorded in female cattle (14.06%), Age-wise highest prevalence recorded in the age group of 3-7 year (15.09%), breed-wise higher prevalence in crossbred cattle (20.00%) and cattle from organized farm recorded higher prevalence (15.65%) than unorganized farm by I-ELISA. Prevalence rate on the basis of previous history or clinical symptoms recorded highest in case of aborted cattle (64.24%) followed by retention of placenta (47.13%) in cattle.
