Seroprevalence of infectious bovine rhinotracheitis in crossbred cattle of Kerala
Seroprevalence of IBR in 719 crossbred cattle of Kerala was studied using Avidin-Biotin ELISA. Sera samples were collected from cattle belonging to different places of Kerala covering all the districts. Samples were collected randomly from cattle of different age, managemental practice, breed, se...

| 520 | 3 | |a Seroprevalence of IBR in 719 crossbred cattle of Kerala was studied using Avidin-Biotin ELISA. Sera samples were collected from cattle belonging to different places of Kerala covering all the districts. Samples were collected randomly from cattle of different age, managemental practice, breed, sex, parity, different health status and also from different farms. Samples were subjected to Avidin-Biotin ELISA for detecting antibodies against BHV -1 infection. Out of 719 sera samples tested 14.88 per cent gave positive result for BHV -1 antibodies. Animals reared under rural farming system showed high seropositivity ,. (18.75%) to B HV -1 infection than animals under organised farms. Seroprevalence of BHV -1 antibodies was more in animals with some history of disease (22.6%) than apparently healthy animals. This result is highly significant (P<O.Ol). Prevalence of BHV -1 antibodies is found to be more in crossbred cattle when compared to non-descript cattle. Seroprevalence of IBR in various age group revealed that percentage of positiveness to BHV -1 was more in animals above three years of age. Serological evidence of !BR is very less in younger animals. Also animals after one parity and above had a high percentage of seroprevalence than heifers and calves. Animals from different farms were tested for antibodies against BHV-l infection. Private farms had a high seroprevalence of IDR infection than University farms and Government farms. There is significant difference •. between private farms and other farms. Seroprevalence of IBR among cattle with different clinical manifestations were tested. High percentage of seroprevalence noted in respiratory form of infection (33.33%). Seroprevalence ofIBR in crossbred cattle of Kerala detected as 14.88%. | |
