I just recently purchased a mare (in-foal) from a woman in Illinois. The mare was due to foal in late May, and I was to have her shipped to me this week. I got a frantic call Friday AM that the mare had aborted twins. The crazy thing is that the previous owner had her checked by her vet at 16 days, and 59 days and the vet said "healthy foal"---no mention of twins. I looked on the internet and 60 day of fetus are about 2.5 inches long. How could this not be seen?

It is my understanding that checking for twins should be done before 60 days. My vet likes to do a check on day 15 to check for pregnancy, then a check on days 30 and 45 for twinning and pinching off if necessary. By day 60, the foal or foals can be hard to spot as they can tend to dip behind the pelvic brim. One fetus could have easily been hiding behind the brim and only one was visible.

We check our mares a lot for twins. Twice is not enough. We check at usually about 15 days, 18 days, 20 days, and 25 days. Then again at 45 and 60 days.

It's happened many times, and sometimes even the best vet can't find a twin hiding. We feel that the more ultrasounds we do, the better chance we have of finding a twin.

We u/s at 18, 30. 45 and 60...but with certain mares on a slightly different schedule...if they usually twin we check more carefully, if they have lost a pregnancy in the first 45 days we are more careful, with a maiden with no history we may check more often...

We check at 15/16 days 18-20days, 30 and 45. The reason we check for twins at 15/16 days is that at day 16 the embryo becomes fixed and stops moving around the uterus. If the twin pregnancies fix close together it may make pinching of one difficult and both may be lost, prior to 16days the vet can move the embryo. The second san is done at 18-20 days because two ovulations may not be at the same time and there may be a second pregnancy that is 4-5 days behind the first and this may have been missed in the earlier scan.
