This message is from: [EMAIL PROTECTED] Hi Rhonda, I have a mare with exactly the same problem. She cycles fine, gets in foal easily, but will only carry for a few months before aborting. With her, the problem is a damaged uterine wall, probably from a uterine infection at some earlier point in her life. She has the hormones to support the pregnancy, but not the uterine structure, and so when the fetus starts to grow, she slips the foal. You might want to have your vet do a hormonal check-up on her (hormonal imbalance could cause the same problem), as well as a uterine biopsy. It's a simple procedure ,and will save you a great deal of stress if you can figure out what is going on. Jan
