Abstract
A cross-sectional study was carried out to identify risk factors for bovine viral diarrhea virus (BVDV) infection in 62 randomly
selected dairy herds which were tested for BVD serum antibodies by using an indirect ELISA kit (IDEXX). Results from the chisquare
test analysis were interpreted by analyzing by chi-square test. A sum of 500 sera samples were screened and 66 animals
(13.20%) showed positive for BVDV antibody. Within herd, BVD seroprevalence was 12–65%. This study concluded that
epidemiological risk factors like location, herd size, housing patterns like, tail to tail system, roofing pattern, distance between
the manure pit and farm, and distance between farms were significantly associated with BVDV serological status (P < 0.05).
