I don't have a photo at the moment, but our Arab mare was bred AI and checked via ultrasound in foal at 17 days after AI back in July. She would be due the 28th (AI was on the 20th of June) of May.
We moved her back here from Lexington, Ky, and we have no access locally to ultrasound and since she hadn't been palpated before, our vet didn't seem to want to do it since she is not the easiest to handle - she'd have to be tranquilized. . .so I thought we'd just wait it out and see.
This would be her first foal. She is a hard keeper, and we changed her feed about 1 1/2 months ago, and so I am not sure if her slightly heavier body is from the feed change or pregnancy. She hasn't appeared to be in heat, but I've NEVER seen a mare this close to foaling look this small - I really don't think she could still be pregnant, but my question is whether you guys have had a mare that DID not look pregnant a month and a week before foaling that actually was pregnant.
This was 20 days or so after AI last year. She MIGHT be a SLIGHT bit larger in the middle now, but I doubt it.
