Who We Are

The Equine Theriogenology service is composed of three faculty who are board-certified specialists in veterinary reproduction that work exclusively on the equine and companion animal reproduction services. Additionally, the service has two resident veterinarians who are training to become specialists. The service has two dedicated veterinary technicians who assist the veterinarians and senior level veterinary students in managing the service.

Stallion Services

The Center offers stallion services including collection for semen processing and shipping, stallion training, and stallion management for the breeding season. When select client-owned stallions stand at Auburn University, the faculty and staff manage all aspects of the semen collection and shipping process including primary contact with mare owners to ensure the shipment arrives on time. The staff at the ERC are in communication with the stallion owner and semen is shipped only when a breeding contract is confirmed. Semen cryopreservation (freezing) is also offered and can be performed during a short visit or anytime during the breeding season while the stallion is standing at Auburn. For pricing and booking information, contact the Large Animal Teaching Hospital front desk at (334) 844-4490 or email stallions@vetmed.auburn.edu.
