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.

Have 4 yr. old mare born 3/00.
Mother died of colic 8/99, fetus transplanted.
Guessing more expensive than embryo transfer, Wondering if the odds of succcess are more,less or same?

Dr. O- Not sure, the mother died 8/9/99, was not sudden, she had been having increasingly severe colic episodes for several years. The transplant had normal birth 3/22/00. Done at Cre Run, in VA, large Arab flattrack breeding and training farm. About 7.5 months in birth mother.
They might have 50-70 births a season there, vets on staff, probably stand by mare if mother lost giving birth, but this was different, from a resource standpoint alone, can't be very common. Might be written-up somewhere, never asked them. Be a good nature/nurture study. I have her older half sister, same genetic mother, their attitudes are similar.

Timothy I have to admit to being very skeptical about a "fetus transplant". I have never heard of this even being attempted in any specie including humans so assume this is actually a embryo transplant done prior to day 9 of the pregnancy.
