I have a 14 year old mare that the previous owner told me was too small to be bred by live cover, but that she would have to be bred by AI the first time. They had her checked by a couple of vets and they said that she was too small for a stallion to enter her, so she would have to be bred AI the first time. They also said that she could deliver a foal with no problem and then be bred by live cover after that.
Does this sound reasonable? I haven't had time to get her to my vet since I bought her and I thought someone here may have had a similar experience.

huh? if she is too small for live cover how can she deliver a foal?!?!?!?
I am no expert but i feel pretty confident that "HE" is probably smaller than a foal....

I guess my thoughts would go with Kris on this one. As well, to ai a horse a humans arm must go into the mare. Humans arm vs. the penis of a male horse ? Depending on the human doing the ai procedure size seems to be similar, if not larger for the human males arm. You just don't stick the pipette into the mare, you must feel where the pipette is going for the procedure.

I have heard that if she is a smaller maiden mare it sometimes helps to have the hymen ruptured by a vet before breeding. My stallion has not had any problems with breeding a maiden mare. I was given a mustang paint mare that bred at 19 months old!! And at 2 1/2 she was only 14 h and she delievered a fine healthy filly with us..( we did put about 150lb of good flesh and she grew about 4 inches since we got her)

I too would be skeptical that the mare would safely deliver a foal. I know of someone recently whose poor mare had this problem but didn't know until after she was bred. Mare has been pretty torn and her future as a brood mare is over. Very sad.

The uterine environment is the determining factor for the fetal size, so it is unusual that a mare will produce a foal that is "too large" for her to deliver. Dystocia on the other hand can present a problem - and associated damage - regardless of neonate and mare size. Where problems usually occur they are often related to the width of hips and shoulders and depth of chest, and that is more a matter of genetics than mare size. It is always worth while considering the conformation of neonates from a certain stallion before breeding a deep/wide-chested/rumped stallion to a small mare. Height doesn't enter into it - this has been shown several times with research projects crossing draught stallions on Shetland mares (which foaled without trouble).
