I would like to explain why I describe the issues with foaling. We have some family friends who take great care of their horses but have had some bad luck. They have had foals with contracted tendons, map-positioning issues, foals with seizures and mares that colic after foaling. These are difficult things to watch and while it is rare it is devastating to see. Dbarabians you are very lucky to have been breeding as long as you have with so few issues. You also with all due respect have a farmers mentality with respect to horses that many people do not have. This is a good thing when you are in the breeding business. You regard your horses as horses and not as pets or best friends. That is not a sentiment that is shared by everyone who breeds a horse.
I know that foaling issues are rare but when they happen they are bad. I think a portion of the people I see in the world regard difficulties in equine pregnancy the same way they regard difficulties in human pregnancy. There are children born at 6 months gestation who are living. We don't have the same chances with pre-term equines. The other thing is that these complications while rare are often expensive, which is something that owners sometimes forget in the excitement of having a foal.
I am sorry for sort of hijacking that but I wanted to explain why I tend to be the one jumping on the "bad things happen when you breed" bandwagon.
