Ultrasound/Progesterone Assay

[albahurst]

I had a mare ultrasounded on Monday for a foal check. One horn was not visible because the mare's bladder was full. Since we could not be 100% sure from the ultrasound, I had the vet do a Progesterone Assay, which indicated no pg. Now, however, today I needed to chat with the vet regarding another matter of this mare and she said we do not know for sure if the mare is in foal or not. I was thinking the Progesterone Assay would have given us a pretty good clue about that matter. The mare should be about 50 days if she was in foal.

Anyone have experience with this type of scenario?

WE USE BET REPRO LAB IN KY... http://www.betlabs.com/ MAYBE ASK WHERE YOUR TEST WAS SENT... ASK FOR A COPY OF THE RESULTS AND MAYBE COMPARE THE NUMBER FOR YOUR MARE TO THE NUMBERS GIVEN ON THIS WEBSITE... GO TO THE EQUINE SECTION AND IT WILL GIVE YOU A CHART. BE A DETECTIVE... I HOPE THIS HELPS. REALLY A PMSG LEVEL SHOULD BE USED ON MARES AT AROUND 50 DAYS...

The vet ran it at her clinic. She said the other test was a possibility at about 60 days, so that is why we did not do it this time around and just ran the other.

I am thinking I may need to do the test you suggested?

This mare never came back into heat, that I could detect, and she shows heat cycles very clearly. This would be her first breeding, as she is only three.

Thanks!

At 50 days it is very easy to see a pregnancy.

If she was pregnant, the vet missed it.

Well, the first vet missed it! I took my mare to another vet that I think does a great job- (110 miles away, though) and there is a foal in there, for sure. Exactly as I thought- guess I should go on my instinct about my mares. Anyway, just found out late this afternoon about the foal. This vet said it was very easy to detect- at 53 days.

Now, I am curious about the Assay, though. Wonder if the first vet ran the test incorrectly or ?????
