Foal Size

Hi Guys,

I'm thinking about breeding my quarter horse mare and I was wondering about foal size. My mare is about 13.2 HH because she was stunted as a foal. She is supposed to be about 15.2 HH. She is big and thick but not very tall. So, what size do you guys think a foal would be out of her and a 16 HH stallion? The stallion is also a quarter horse but he doesn't have as much muscling as she does. Do you think the foal would more closely resemble the mare or the stallion? Any ideas, experiences? Thanks!!


Side Note: I'm not a backyard breeder...I've put a lot of thought into this because I want to improve on my horse's traits. Also, I was informed by a vet that she shouldn't have any trouble delivering the foal because the mare determines how big the foal can get while she is carrying it.

No guessing on the size. It all comes down to a crap shoot. You could get larger or smaller then either the sire or the dam...

If your mare was supposed to get to 15.2 and the stallion would be 16 it would be reasonable to expect the foal to eventually grow to somewhere around the same. By the same token, if the mare was stunted and is small now, then her foal may not get as big as you would expect. She may have a harder delivery of a bigger foal, too.

I don't think the mare decided how big the foal is going to grow to, its not that simple. Thinking of dogs, all the time there are pups that are to big for the female and die during birth. The same token can happen in this, what exactly made your mare stop growing? Just curious.

Actually the mare does decide how big the gets foals in utero.....you can breed a sheltand mare to a clyde stallion and the foal will only be as big as the mare's uterus will allow......but once the foal is born genetics take over.

:roll: Actually, if I am remembering rightly, that has proven to not be totally true. In most cases it seems to work that way, but there is always the chance the foal will be to big. Otherwise, if the mare controlled the in utero growth, there would never be any deaths from foals to large for a mare to birth.

There are exceptions to every rule....but generally it holds true.....often malpresentation is more of a worry than size.

I see lots of ponies being breed to horses with no issues.

The foal will not get too big for the mare's uterus...but that doesn't rule out other problems. Apparently horses don't have the same problems as dogs. My mare is shorter than she is supposed to be because she did not receive the proper nutrition when she was a foal or when she was in the womb.
