Out of 250 animals tested, 2% showed positive reaction. The higher prevalence of bovine brucellosis was recorded in pregnant cows (3.45%) than non-pregnant cows (1.23%). The age wise prevalence of brucellosis in cows older than 4 years of age were found to be more susceptible to infection. The prevalence of brucellosis in cows above four years of age was recorded 2.56% whereas, 1.10% positive cases were found in cows having less than 4 years of age. The prevalence of brucellosis in cows with repeat breeders, previous abortion and retention of placenta was recorded 1(1.64%), 3(12%) and 2(7.41%) respectively. The highest prevalence was recorded in cows with a history of previous abortion. The prevalence was higher in retention of placenta in comparison with repeat breeder cases. Keywords:
