University of Tehran Press Journal of Veterinary Research 2008-2525 56 2 2001 07 23 - - 16427 FA Journal Article 1970 01 01 Bovine viral diarrhoea virus (BVDV) Is a major reproductive pathogen in cattle population throughout the world. A significant percentages of cattle of Iranian dairy farms have been detected to be seropositive to BVDV. Recent field and experimental studies have confirmed the negative impact of BVDV infection on the early reproductive performance of cattle. In the past decade, much progress have been achieved to explain the pathogenesis for low fertility in cattle undergoing a transient infection with BVDV. Disturbance in follicular development, ovulation and consequently corpus luteum formation are the main adverse effects of BVDV infection around the time of artificical insemination in cattle. This paper focuses on recent advances in the understanding of the pathogenesis of early reproductive loss associated with BVD virus infection.
