After reading a thread on here I'm worried as I have a 14.2 in foal to a 16.2 she is a maiden mare. I was told the mare can control the size of the foal but I have read she carnt. This mare is my life and bred from her to get a bigger version of her a fiesty hot pony. Has anyone had any trouble with this in mares Posted via Mobile Device
My mare had a foal this April. She is 14.2- 14.3 as well, and the stallion was a 17.2 (and growing) Clydesdale stud. There were no problems with the pregnanc or birth, and baby was born healthy, although she had a little trouble figuring out her long legs lol.
I think that as long as you stay within two hands, everything will be fine, although the stud was 3 hands taller than my mare, and everythig was still fine.
The foal will only grow as big as the mare's body will allow. If the foal is going to be huge, it will do the rest of the growing once it is born.
I forget when and where, but some scientists did a study on if the foal can actually grow bigger than what the mare can deliver, by breeding shetlands or mini mares, to shire stallions. All the mares delivered without trouble.
Here's a pic of my mare and filly when she was a day old. My filly is now 7 months and over 13 hands.
I don't think you'll have any issues. It's not like you bred a TB to a Shetland lol, the height difference isn't that bad really. I bred my 13.3 WelshXQH mare to a 15.3hh QH stud & she had no problems.
Horses are unique in that they almost never have any birthing problems. If the foal gets too big in the mare then she will get rid of it. I read about a study at a university where shetland mares were inseminated with draft semen. Every mare foaled a healthy colt that grew like a weed but stayed nicely healthy. Don't worry about your mare.
I had the same concern as I've been thinking about breeding my mare sometime down the line, and wanting to breed her to something a bit bigger. I would like to breed her to a warmblood at some point, and she's only 14.2ish hands. A breeder I talked to told me that the size of the stallion and the bone mass wouldn't make a difference as to the size of the foal while in the uterus. I wouldn't worry about the size difference, and definitely post pics when she foals.
Kevin's right - the baby will only grow so big as the mare can handle, it'll just grow fast after birth. Don't worry about it, but if you still are - talk to your vet... maybe have your mare cassilised?
