US - Producers and veterinarians alike are struggling to find ways to manage a tiny, common swine virus, and understand why it is suddenly creating havoc in a growing number of U.S. finishing barns.Porcine circovirus is no stranger to the pig world. It's been regularly diagnosed in U.S. herds for years. In fact, there are only five or six herds known worldwide that have actually tested negative for the virus.
Iowa State University (ISU) has documented several hundred cases of the virus dating back to the late '90s. But its true impact on production has been questioned in a number of veterinary circles in recent years.
That's certainly no longer the case. Last fall, porcine circovirus-associated disease or PCVAD (formerly known as postweaning multi-systemic wasting syndrome or PMWS), began to inflict heavy losses across the hog belt.
