Embryo transfer (ET) is widely practiced in other species and humans but remains a fairly rare practice in horses. The reason is because of both practical problems that remain unsolved and the lack of acceptance by some breed registries, most notably Thoroughbreds. None the less it remains the best option is some cases. The advantage of ET include:
  • breeding mares that have medical or physical reasons they cannot carry a foal to term,
  • breeding mares that need to continue to compete during the normal gestation,
  • the possibility of creating multiple foals from a mare during a single season.
With improved techniques ET will gain greater acceptance and become a more important equine reproduction technique. This article discusses the current status of ET, the technical problems, success rates, and techniques. Included are a number of scientific research summaries.
