A study was conducted to ascertain the prevalence of Bovine tuberculosis at 135 commercial dairy farms of five upazilas of Sirajganj district of Bangladesh during the period from January 2012 to December 2013. During two years study period a total of 270 blood samples were tested by Antigen® Rapid Bovine TB Ab test kit. The overall prevalence of bovine tuberculosis was recorded as 7.78%. Distribution on the basis of age, sex and breed revealed the significant relationship among the infection, breed, sex and age in the population. The prevalence was relatively high in older cattle (10.23%) and the highest prevalence was observed in the female (9.09%). The prevalence of tuberculosis infection was considerably high in most of large herds. It was evident from the study that cattle were infected with organism and caused a serious economic loss.DOI: http://dx.doi.org/10.3329/bjvm.v12i2.21276 Bangl. J. Vet. Med. (2014). 12 (2): 141-145
