I have a mare who was bred once last year and took on the first cycle. She was ultrasounded at 18 days and was determined to be in foal. And never came back into heat after that. And she is one you cannot miss her cycles on. We had her pastured with the stallion and they never bred again. She should be due(342days) April 4th. But she is not showing AT ALL. Are there some mares that just don't show. This is her 2nd foal, the last being 7 years ago. She is a long bodied mare, but I would have thought she would show some by now. I guess my question is how late in the pregnancy can a mare reabsorb.

Dani, If it makes you feel any better I have a mare that will be 340 days Apr.12 and she isn't showing at all either. But, I do know that she is in foal because I have felt the baby moving and on occassion have even seen it move. This mare has never shown that she is in foal with any of her pregnancies, and I have also wondered why it is that some mares are capable of hiding their pregnancies so well. As for reabsorbing, I think it is usually within the first 30 days but I could be wrong. Start putting your hand on the mare's belly and see if you can feel some movement. You'll have to be patient though because it could take a while to feel anything. That was the only way I knew that my mare is still pregnant. If it wouldn't have been for feeling foal movement, I would have sworn she was not in foal right now.

Dani...mares can absorb I believe into the 4th or 5th month. They say past 120 days you are usually ok but on some occasions they can either absorb, slip, abort. Mares tend to lay dormant for the winter with less sun light also so she may not have come back into heat for the winter. Is she showing any signs of bagging up or anything. I would have my vet out to stick an arm in to determine if she is still pregnant. No sense having sleepless nights waiting for a foal if you don't have to. Is she a large barreled mare? Good luck.

Actually there is no such process as "absorbing", "resorption" or "reabsorption". In all cases, the pregnancy is lost through the cervix, but (especially early in the pregnancy) the conceptus or embryo is so small that it is not detected. There is therefore, no correct answer as to how late a mare can "absorb"!
The technically correct terminology is:
Prior to day 15 of pregnancy: Early embryonic death
Between days 15 and approx. 40: Embryonic death
After about day 40: Fetal death
I do however always encourage persons facing a dilemma in the spring as to whether their mare is still pregnant or not to have the mare checked! This may be achievable by rectal palpation, but is definitely achievable by estrone sulfate assay.

Just thought I would add this mare IS in foal after all. She is at 341 days and still not showing at all...LOL So I guess this mare just carries it well! Thanks for all the input!

Dani My mare did not show til she was 7 1/2 months and she is an Arab. Some of the larger / longer bodied mares might not show at all depending on how the foal is positioned.
Good Luck and let us know when she foals
