Can a stallion be tested for Eva status?

Can a stallion be tested for Eva status?

If blood test results are positive in a stallion, but there is no official documentation of negative EVA status prior to vaccination, the stallion must be tested for the presence of a carrier state. Virus isolation can be attempted on the semen from two separate ejaculations, or by mating two EVA-negative mares with the stallion.

Do you have to breed an EVA negative horse?

Blood samples for EVA testing should be collected from all horses before breeding, and virus isolation should be performed on imported semen before use. Strict hygiene and disinfection of instruments and equipment are essential to minimize spread of the virus. EVA-negative mares should be bred only to EVA-negative, noncarrier stallions.

How is Eva transmitted from horse to horse?

EVA is transmitted by infected mares, through the placenta, to their unborn foals. EVA is transmitted to breeding partners of acutely infected stallions and mares. The virus can be transmitted via fresh-cooled or frozen semen used in artificial insemination. How can EVA be prevented?

Can a mare get Eva and have an abortion?

Because EVA can lead to abortion in mares, it is a major cause for concern among horse breeders. But, control and prevention of EVA is easy, when one first understands some facts about the disease. What is EVA? Equine Viral Arteritis (EVA) is caused by the equine arteritis virus (EAV).

Why is Eva so important to horse breeders?

While it is rarely life threatening to otherwise healthy adult horses, EVA is of special concern to horse breeders because it can cause abortion in pregnant mares, death in young foals and render breeding stallions permanent carriers of the virus. Although EVA outbreaks occur infrequently, EAV is present in horse populations in many countries.
