Seroprevalence of Bovine Viral Diarrhea Virus and Factors Associated with the Serological Status in Dairy Cattle in Western Region of Thailand

Background: Bovine viral diarrhea virus (BVDV) causes productive losses and reproductive failure in dairy farms. This study defined the seroprevalence determined factors associated with BVDV infection cows western region of Thailand. Methods: Blood samples were collected from 732 30 randomly selected herds. The antibody was detected using a commercial indirect ELISA kit (IDEXX®BVDV Total Ab, IDEXX Laboratories Inc., Maine, USA). A questionnaire about herd management used to collect data via interviews farm owners. variables identified by Fisher’s Exact Test (p less than 0.20) then analyzed multivariate logistic regression. Result: Individual prevalence 36.89% (270/732), while 93.33% (28/30). Significant risk based on univariate analysis as area, size, feeding type, history abortion, pen calving, biosecurity pet 0.05). Biosecurity no disinfectant (p=0.02) (OR, 1.32; CI 95%, 1.038-1.669), (p=0.03) 4.72; 1.142-19.501) abortion (p=0.00) 0.02; 0.004-0.140) significant, regression analysis.
