|OSU Hosts Horse Owner's Symposium - Control and Prevention of Equine Viral Arteritis|
Horse owners recently attended a symposium on equine healthcare, which was hosted by Oklahoma State University Center for Veterinary Health Sciences and Department of Animal Science, Division of Agricultural Sciences and Natural Resources, and the Oklahoma Cooperative Extension Service.
While many important topics were presented, one particular segment covered the control and prevention of Equine Viral Arteritis (EVA). EVA is a disease that affects horses. In the acute phase of disease it causes generalized illness primarily of the respiratory tract. It can also cause abortion in pregnant mares and pneumonia in new born foals. In stallions after the acute respiratory illness resolves, 30–60 percent may become persistently infected shedding virus only in the semen from months to many years, serving as the natural reservoir in the horse population.
According to Reed Holyoak, DVM, PhD, DACT, associate professor of Theriogenology and Bullock Professorship in Equine Theriogenology, the key is to restrict dissemination of EVA in breeding populations. Dr. Holyoak offers these tips to help horse owners prevent EVA.
“If these practices were implemented, over a number of years we would see a great reduction in the number of carrier stallions,” says Dr. Holyoak. “Following these recommendations would effectively eliminate the primary reservoir of EVA.”
