Bovine Viral Diarrhea is considered as one of the difficulties in industrial livestock whole world. If it went out of control, can causes significant economic losses. The eradication of the disease requires serological and molecular studies due to the presence of animals with persist infection. This study’s purpose is prevalence assessment of this disease in Golestan province. In order to do this, serum samples were taken from 200 cows (which) selected from industrial and traditional farms in 6 cities of the Golestan province randomly and they were tested for the presence of antibodies against BVDV by standard ELISA kits. The results showed that the prevalence of BVD antibodies in obtained serums is 22/92 percent. The most prevalence is related to the Bandar-e-Turkman county and the least prevalence is related to the Aliabad county. The prevalence of the disease in industrial farming system was more than traditional one (p<0.1) and there was a significant relationship between increasing age and number of claves with increasing antibody titer. Thus, the high serum prevalence of infection in farms in Golestan province refers to spread of pollution and economical importance of controlling the disease. Emphasis on changing the approach to livestock industrialization can help controlling the disease beside other preventive measures.
