My friend has a wonderfully bred Arabian mare (18 years old) who has been difficult to breed for many years. She did have a lovely foal two years ago, but has not been able to conceive since then. Sometimes she does not come into heat even with teasing and the hormone shots. We have been thinking she may be a good candidate for embryo transfer-- Do you know of a source for this in Texas, or do you have any suggestions?

Texas A & M will probably be the best place for you to start, but I must warn you that older mares are generally not good donor mares as the conceptus seem to be of a poorer quality (this is also another reason why one sees a higher incidence of EED in older mares), so AI would probably be a better starting point, using a single insemination as close to ovulation as possible and following up the breeding with oxytocin use as outlined here.

Good luck!

I have just recently purchased a mare. This is the first time I have owned a horse as well as cared for one completely. She is in heat presently, and I was wondering how long this lasts? I also wondered when she will be in heat again?
Thanks for any advice you can give me!

The entire cycle is approximately 21 days - that is from ovulation to ovulation.

Estrus ("heat") lasts approximately 5 to 7 days and most mares ovulate in the last 24 to 48 hours of estrus.

Diestrus - that stage in between "heat", is therefore about 14 to 16 days.

Generally the mare should be bred on an every-other-day basis starting on the third or fourth day of "standing heat" (which is the stage at which she will accept the stallion) until she rejects tha stallion's advances. Breeding more
often than avery other day, except in special circumstances (with a subfertile stallion for example) will usually not produce a greater chance of pregnancy and in fact may well reduce the chances owing to a greater post-breeding uterine inflammatory response.

Hope this helps.
