Description |
The present study has been taken up on sero epidemiology of bovine viral diarrhoea (BVD) in dairy cattle of the north-western zone of Tamil Nadu. A total of 500 sera samples were subjected to indirect ELISA to assess the BVD seroprevalence in the study area. Out of 500 sera samples screened, 66 samples were found to be positive for BVD antibodies with a per cent positivity of 13.20 by indirect ELISA. Out of 62 farms screened, 17 farms were found positive for BVD with a per cent positivity of 27.41. Out of 500 samples, 77 sera samples were randomly selected and screened for BVD antibodies by virus neutralization test, 22 sera samples were found to be positive with a per cent positivity of 28.57. Among the 22 positive sera samples, 16 samples (72.72%) were positive for BVD-1 and 19 samples (86.36%) were positive for BVD-2. Twelve samples showed both BVD1 and BVD2. Among the virus neutralization-positive samples, 13 animals (59.09%) showed reproductive failure, two animals showed enteritis & mastitis, 27.27% (6/22) animals were pregnant and did not show any clinical signs and one animal showed pneumonia. It was concluded that the BVD1&2 genotype causes reproductive failure among the dairy cattle of Tamilnadu
