    Even without him being tall, there are reports of mares "cushing" (term for a camel going sternal, best term I can come up with for this application) to accommodate mounting by a stud. While not the "norm", it can happen

    Just because a mare is older doesn't mean she can't get prego.

    Try telling this to our mini pony. Every few weeks one of the mares has hoof marks on their rump. And he's gelded! He can't reach, but sure tries.

    Foal
    Man I have mixed emotions, I can't wait til Tuesday to know for sure. I've done research on older mares and found there is only 30% chance she is prego if covered only once, I'm sure she was covered more just not sure how successful he was. Does anyone know the likelyhood of the little guy getting it right more than a couple times? Guess I need to do some colt research too. If vet says she is pregnant and does not expect problems, I know there is always a chance, I think I'm going to let nature take its course, I'll just be extra prepared if that's possible.

    It's not really nature.............. In nature, the colts get kicked out and arent locked in a pen with a mare to themselves. The proven wild stud then breeds the mare, because he won the survival of the fittest thing enough to have his own herd of mares.
    In the mare and foals best interest, it would be good to abort.

    actually this statement is incorrect. There are minimal health risks with breeding an older mare as long as she is not a maiden. The more often/regularly she was bred, the easier it will be for an older mare to carry to term without issue. Of course the mare must be in good health and weight for this to hold true. There are risks, yes, however many of them cause the mare not to carry to term and abort early on which is nature's way of saying her body is not able to carry this baby. Here's some great reading:

    The Horse | Breeding the Older Mare
    Beyond that first 40 days, mares of all ages are at some risk of abortion due to a number of infectious and non-infectious causes such as twins, herpes virus, fescue toxicosis, etc. The older mare, in particular, is more susceptible to ascending uterine infections due to potential cervical incompetency and/or poor external conformation.

    I thought it was interesting to read that infection seems to be the highest cause of abortions in older mares and that it can be relatively well managed to prevent this.

    Also just as interesting was that overbreeding caused as many risks as underbreeding. By that I mean a mare that has produced a foal nearly every year will have uterine stretching, while a mare that has never produced and is a maiden in her late teens will have as many risks for the converse reasons. Ideally mares (intended as broodmares) should be bred every other year with a year off in between babies. Some breeders do 2 years bred, one year off which is also acceptable from what I have read.

    All that said - I know none of this really applies to the OP as this was not an intentional breeding. However should you choose to keep the baby (if the mare is pregnant) I wanted to share as that is a great article!

    I think I found the article you read-- It refers to older mares needing to be bred "twice as often" to achieve a pregnancy-- - IMO that means an older mare on average needs to be bred twice as many cycles as compared to a younger mare to get pregnant-- NOT that during each cycle, the mare needs twice as many covers.

    In most cases, It only takes ONE cover at the right time to impregnate a mare, no matter the mare's age.

    Sperm only live so long, so if one breeding took place at the optimum time in relation to the mare's ovulation, so that the sperm were alive and active when they reached a fertile ovulating egg, then pregnancy would be achieved from that one cover. Any covers made too early before ovulation would mean less chance of conceiving, because the sperm would be weaker or dead--they would have swum up the reproductive tract of the mare, but would have to "wait around" for ovulation.... any covers made after the mare ovulated would mean the egg was already on its way out or already gone and the sperm could have completely missed it.

    Said another way-- just because a mare is older does not mean that "banking" sperm in her reproductive tract by multiple covers would be of any benefit as far as rate of conception... because if the sperm are viable, timing is much more important than volume or frequency.

    Also, being covered more often than necessary can have adverse affects-- pathogens, germs, debri, etc are potentially introduced in the reproductive tract more often, and some mares actually have sort of an allergic reaction to semen, which can cause inflammation of the uterine lining, failure to expell excess fluid from the uterus, etc..... meaning, in some older mares, for optimum chances of a pregnancy, the less covers the better-- as long as the cover or covers that ARE made are well timed.

    Even this isn't really true. When I rescued my mare, she was housed with a tiny stud. I would guess he was like 10 or 11 hands!? And... few months later... little baby! She's a small petite girl now at 4 years old. It happens... somehow?
