Abstract

Brucellosis is one of the most serious diseases in developing countries. For epidemiological study a total of 200 lactating cows were screened for brucellosis from private dairy farms of Satna and Jabalpur. The information pertaining to age, parity, history of abortion and vaccination status of individual cow was recorded. For screening of brucellosis, milk and sera samples were collected and tested by MRT, RBPT and STAT. The overall occurrence of the brucellosis in cow was recorded as 13.50% by MRT, 18.00% by RBPT and 26.00% by STAT. Higher occurrence of brucellosis was found in crossbred cows 18.18% by MRT, 22.72% by RBPT and 34.09% by STAT, in comparison to indigenous cows i.e. 4.41% by MRT, 8.82% by RBPT and 10.29% by STAT. Age wise highest occurrence recorded in cows above 6 years of age while no seropositivity was observed in cows up to 2 years of age.
