SEROPREVALENCE OF INFECTIOUS BOVINE RHINOTRACHEITIS IN CATTLE.

A total 100 serum samples of cattle were screened for IBR in which 19 per cent samples were found to be positive by avidin-biotin ELISA (AB-ELISA). Animals of 3-5 years age group showed more seropositive (25.71 per cent). Breed-wise analysis of data showed highest seroprevalence of IBR in Holstein-Friesian breed (26.08 per cent) while Rathi cattle (16.66 per cent) and non-descript cattle showed (17.14 per cent) seroprevalence of disease.
