Abstract
A cross sectional study was carried
out to identify the seroprevalence and risk
factors associated with bovine viral diarrhea
(BVD) infection in non vaccinated dairy cattle
herds of north western part of Tamil Nadu
between September 2014 and August 2016. A
total of 500 sere samples were collected from
62 dairy herds and indirect ELISA was carried
out for BVD antibodies. A pre defined
questionnaire which included variables
related to herd size, frequency of purchase and
pattern of purchase of new animals was
collected from each herd. A herd with one
animal positive for BVDV antibodies
considered BVD sero positive to calculate
herd sero positivity. The overall sero
prevalence in the study population was
13.20%. The Chi square model showed that
flock size, location and animal purchasing
pattern were the potential risk factors
associated with BVD infection in dairy cattle.
