Badiei K, Ghane M, Mostaghni K., Prevalence of bovine viral diarrhea virus antibodies in industrial dairy cattle herds, Onl J Vet Res., 24 (2):87-93, 2020. A cross-sectional study was done to report prevalence of bovine viral diarrhea (BVD) virus by indirect enzyme-linked immunosorbent assay (ELISA) test in industrial dairy cattle herds in suburb of Shiraz (Iran). Blood samples were collected from 952 dairy cows of different parities in 43 herds. None of the herds were vaccinated against BVDV. The cows were divided by location, herd size, and parity and production level. Five hundred seventy three (60.19%) cows were ELISA seropositive. However, the true BVDV seroprevalence was 59.46%. All of the herds were antibody positive against BVDV. Prevalence ranged from 37 to 86% within the herds. There were no significant differences between the presence of antibodies to BVDV and herd size. The proportion of seropositive cows increased with their parity (P<0.05), but there was no difference between seroprevalence of BVDV amongst cows in different production groups and location. Results suggest persistent infection was responsible for presence of antibody in blood.
