Hello, I know that a study was made by breeding Draft Horses to small Ponies.These informations were provided by Dr.Garth Graham of Guelph University located in Ontario Can. He told me to go ahead and breed my 12.1H ponie to my 16.3H stallion.They noticed that the foal is born smaller due to the uterus size but tends to grow faster.Another reproduction specialist told me the same thing. BUT all my vets. and friends with a great deal of experience in breeding horses think I'm "crazy". Did you find any informations on that subject?

A mare will not generally produce a foal larger than she can deliver. Genentics will kick in and a small foal at birth can grow quite quickly.
The foal gains much of the fat during the last 30 days of gestation. If you are concerned about a difficult delivery, consider that an overweight mare is at more risk of a difficult delivery. Fat does not mean heathly, and I find that many horse owners associate a fat mare as a healthy one.
I have one mare that is a smaller type, and has had 3 foals. The first 2 looked skinny and gawky to me at birth. She had no trouble with the delivery. I intentionally feed her a higher fat diet during this last pregnancy, and the delivery was her most difficult. I had to assist her by gently pulling during contractions.
The foal was the size of a week old colt. He looked prettier than the others at the same age, but would have caught up in weight gain anyway. My point is, watch the weight gain if you are concerned about a smaller mare having a difficult delivery. The more fat surrounding those shoulders of the foal, the harder it is to push out.
