Does anyone know whether there has been any research on breeding pony mares to large horse stallions? I heard mention once of an experiment done at a Canadian University where pony mares were bred to draft horse stallions. According to the person posting the info, it was found to be safe as far as delivery of the foal. I hope to find some good research or veterinary articles establishing safety factors to consider. If you know of any research or articles, I would greatly appreciate leads. Or if you have experience in this area, let me know what you think.

I dont really have a solid answer to help but I had heard that the mare really 'monitors (for want of a better word) the size of the foal but that it is best not to go to extremes of size...

Why would you want to do that cross?
My vet tells me that at one point they did an experiment where they bred Shire stallions to Shetland mares and vice versa. The foals from the Shetland mares were small, and the foals from the Shire mares were large. Unfortunately it would appear that they did not track the adult height of the offspring which would have been interesting to know.

I have a section A welsh stallion (11 hands) that I plan to breed to larger mares to produce large hunter ponies. I know that I can go the AI route but with the smaller of the mares I would like to try natural cover. I would like to know if there is any guidance on making the depression in the ground for the mare. How deep? How steep? Sides?

Dig the hole about the same depth as it is heighth between the stallion and the mare. Make the hole about three foot wide. I would also make the sides straight up and down.

You would be better off breeding on a hillside if you have that option. The trouble with a dug hole is that if the mare walks out of it during the breeding process, then she "grows" while at the same time, the stallion is walking into the hole, so he "shrinks". Breeding on a hillside, if the aimals do move forward, they both get lower at the same rate.

We have bred our 10 hand pony to larger stallions for 4 years, without any problems. The first time it was to a 14.2 hand stallion, and they other times have been to our 16 hand QH stallion. Everytime she has a small-ish foal that grows like a weed for the first 6 months, and ends up lovely.

I have a 17.2 hh stallion I am breeding to a 15.2 hh mare and a stock 14.2 hh mare. I have a 13 hh mare I am afraid to breed him to but she would make a lovely cross with him. I am just worried about the whole live cover thing with her. I think I would have to go AI for sure. She has had four foals but not with anything as large as my guy! Did they use AI with the horses in the experiments? How did the mares do with foaling and nursing?

The Maternal Effects on Growth and Conformation in Shire Horse-Shetland is a study they did in england that may be avalble at your local library in the journal PROCEEDINGS OF THE ROYAL SOCIETY OF LONDON. I couldn't find it on the internet, but it does exist in print. My univerity library has 4 copies. If I get a chance sometime this week I'll look it over for you.

My vet told me about an experiment that was carried out where thoroughbred embryo's were transferred into small pony mares. Even though the embryo's were genetically 100% horse, the ponies all delivered with no problems. The study proved that foetal size is directly related to the size of the placenta. On the downside apparently the "mini" thoroughbreds were slightly deformed

Yes, research has shown that the foal typically grows to fit the uterus but the general rule is that the stud shouldn't be more than 2 hands bigger than the dam.
