Additionally, mares vaccinated for the first time and
bred to a carrier stallion should be isolated from other
equine for 21 days after breeding. Owners of breeding
horses considering vaccination should consult their veterinarians
if the horse may also be shipped in interstate or international
commerce. A specific pre-vaccination protocol to assure
the horse was test-negative prior to vaccination may be
required, because vaccinated horses will test positive
for the disease.
“Several horse breeders and a number of equine veterinarians
have contacted the TAHC about EVA and to urge Texas equine
producers to take all necessary precautions to prevent
establishing EVA in Texas horses,” said Dr. Hillman. “Equine
producers and veterinarians believe this disease can be
handled through judicious application of best management
and biosecurity practices, coupled with appropriate use
of testing and vaccination of breeding animals.”
“The current EVA situation will be reported to TAHC commissioners
at their meeting Tuesday, Dec. 5, in Austin,” he said.
“Development of EVA rules is not anticipated at this time.
Horse breeders are urged to work with their veterinarians
to institute best management and biosecurity practices
immediately to protect their investment and the health
of their animals. EVA can be prevented and controlled
by sound management practices and selective use of the
EVA vaccine.”
