The present study was conducted to ascertain the sero-prevalence of bovine tuberculosis in cattle population of Haryana state. A total of 100 blood samples were collected from randomly selected cattle of a few gaushalas and tested with a commercially available kit to detect the presence of antibodies against Mycobacterium antigens in serum samples. Out of total 100 serum samples, 69 (69 %) samples were found positive for presence of antibodies against M. bovis (BTB) or/ and M. avium (NTM/ Avian TB). The results were compared using chi-square test. The comparison of results for antibodies against M. bovis was found statistically non-significant (p> 0.05) with respect to breed, age, location and gender. The results for antibodies against M. avium were found statistically non-significant (p> 0.05) with respect to breed. However, the results were statistically significant with respect to age, location and gender (p< 0.05). It was evident from the study that the sero-prevalence of bovine tuberculosis was considerably high in the selected cattle population. It could be predicted that cattle were infected with the organism and could be a potential source of infection for other animals as well humans also.
