Thanks Marty for sharing this interesting info I have printed it off for future reference.
I grew up with an "old horseman" for a father, whom would not have agreed with these new findings.
Interesting thing though, we had good horses and never had a horse colic on the farm, no foaling problems, or any major problems for that matter. I think these miniature horses are certainly a breed of their own when it comes to health issues. Thanks again for sharing. Wendy
