Abstract

This study was performed in order to estimate the prevalence of bovine viral diarrhea virus (BVDV), and to determine the main factors related to the prevalence of the infection in cattle of Santa Vitória do Palmar and Chuí counties, in Rio Grande do Sul State. Sera were submitted to the serum neutralization test and an epidemiological questionnaire was filled out in each herd to investigate variables that could be associated with this infection. The sera samples were collected in 85 farms, with or without clinical signs of BVDV infection. From 1.734 serum samples examined, 1.150 (66.32%) in 70 (82.35%) herds were positive. Variables that were identified as risk factors to seropositivity were mixed (dairy and beef) herds, extensive production, use of mechanical milking, use of artificial insemination or artificial insemination associated with natural service, use of the maternity unit at calving and absence of veterinarian assistance (P < 0.05). The results demonstrate the expressive dissemination of the BVDV in cattle of this region in Rio Grande do Sul.
