Bovine Viral Diarrhea Virus (BVDV) is a Pestivirus classified into two genotypes, “Type 1” and “Type 2”, that infects domestic and wild ruminant herds world-wide. In addition to cattle, BVDV is also known to infect camelids and deer. Related viruses include hog cholera virus in swine and border disease in sheep. For cattle producers, the virus causes an estimated $2 billion per year in economic losses through decreased weight gains, decreased milk production, reproductive losses, and death.
