My mare 2 years ago aborted at 42 days...I had the vet come ultrasound as she started acting really silly mare in heat-like....he saw the embryo which was too small and said she was loosing it, and she did. The next year she did not get pregnant. This year she got pregnant on first cycle. 2 days ago, after 2 positive ultrasounds at 18 and 26 days, she started with the silly mare in heat thing again, and is now acting in strong heat (with discharge-infection?)
The vet at 18 days saw some fluid, but said not to worry. Fluid not apparent at second ultrasound.
Any thoughts on why abort 2 times with same timing? What steps to take? Is it too late to try to rebreed her?
Thanks

If it were my mare, I'd start with a uterine biopsy and culture. Abortions in the time frame you are suggesting are commonly associated with endometrial fibrotic changes, which can be identified per biopsy.

Have you tried Regumate? I would put this mare on that 5 days after breeding. Also, some folks use aspirin in pregnant mares for the first 40 days of pregnancy...it is supposed to increase blood flow to the uterus. We have one mare on aspirin therepay now. Whatever decide, good luck.

Eosinophils can be suggestive of windsucking. Have you put a Caslick's procedure in? That might be worth doing.

Re: Regumate use: read the article first! :-)

The article Jos suggested is good. As far as regumate, I would suggest talkig to your vet who is in the best position to make the decision since he/she will see your horse.

I do disagree with the progesterone bit tho'. I have on several occassions seen mares with mid-range numbers lose foals within 30 days ater a confirmed embyo.

I think that the article is more for folks who are considering putting mare on Regumate from the jump but in your case with 2 EED's, I would suggest (I am not a vet) that the fact that a culture has been done with negative results and there have been 2 EED's in this mare suggests that Regumate would be a good choice to try.

Of course the final decision is yours (and your vet's) but 2 EED's in 2 years is frustrating, expensive and I think at this point, you should try some other measures.

Whatever you decide, good luck!

Well, my local vet took a culture (no cytology, he doesn't do that...grrrr) will have results in a few days. He recommends short cycling and putting her on regumate as soon pregnancy confirmed. I did read the article and after thinking about it, I have decided I am definitely one of those breeders who needs the regumate, even if the mare doesn't...after 3 unsuccessful breeding seasons I am about ready to try anything. Last year we did the caslicks, but still no pregnancy.

Total waste of money doing a culture with no cytology. You would have had the same degree of reliability of results if you had elected to do nothing at all, but saved the expense... :-(

Update
I bred the mare, scanned her in foal at 18 days and started her on regumate. Checked her still in foal at 35 days and just checked her at 59 days, everything looks fine. Yeah!!!!
Now, how long to keep her on the Regumate?

We keep our mares on regumate through the pregancy but on decreasing doeses. Some people will stop part way through but we just don't want to chance it.

Before I remove a mare from Regumate, I check Progesterone level with a blood test, then if the value is high enough I wean her gradually.

By 100-120 days of pregnancy, progesterone levels should be base line and barely registering. Additionally, hormonal levels vary from day to day and indeed from hour to hour within the day. A decision made to continue supplementation based upon such a reading is invalid because (a) levels should be zero or close to zero at that point in the pregnancy; and (b) unless multiple readings are taken (i.e. multiple tests), there is no accuracy.

I have a 24-year old mare due to foal in two months. She has been on Regumate since the beginning and I plan to start decreasing it when she has one month to go. I'm not taking any chances.
