i am a new stallion owner - prior to this spring i used a stallion station for my breeding. last fall i had a seven year old stallion given to me and i am on a really steep learning curve here.

february 5, we put the stallion out with two mares. stallion was fine for a few hours, then decided he had to cover one of the mares. she went through the fence (no injuries thank goodness) and that was the end of our pasture-breeding. hand breeding only from now on! mare that the stallion attempted to breed has now not come back into heat - all the other mares on the place have been cycling but this one.

i have been teasing her every other day for the past three weeks and she shows absolutely no interest in the stallion whatsoever. it did not occur to me that she might be pregnant because the 'act' was not completed before she decided she did not want to cooperate.

my question is - is there the possibility she is pregnant even though the stallion did not 'finish'? does ejaculate ever leak out prior to the end?

to be safe, i have a wee foal test ordered but it is not here yet and i thought i would ask. if the test is positive, the ultrasounding will commence. thanks much for any insight.

When the stallion ejaculates, he penetrates into and sometimes even through the cervix into the uterus. The ejaculation occurs at great speed and pressure, so at least the initial portion of the ejaculate is placed directly into the uterus through a combination of penile position and hydraulic pressure. Unlike some other species, the ejaculate is not routinely placed in the vagina.

There are three portions to an ejaculate:
  • Pre-ejaculate, which is the clear fluid seen dripping from the penis prior to intromission;
  • Sperm-rich portion, which is the first three or four ejaculatory spurts and contains the majority of the sperm;
  • Tail-fraction, which contains the seminal plasma and gel (if there is gel) - essentially the major volume of the ejaculate.
As you can see from the above, it is entirely possible that sperm were deposited into the mare's uterus and she could be pregnant. If one sees "leakage" at dismount, it is most commonly part of the tail-fraction, which is most likely going to be gel with a little seminal plasma, not the sperm-rich portion.

Make sure you get the Wee Foal 38 day test kit, not the Wee Foal 120 day test kit (presuming this is the range that your mare is in). They are not interchangeable. If your mare is already 120 days along, then ultrasound is not going to be much help. Note that you cannot use the Wee Foal 38 kit prior to 38 days and in fact are better waiting until around 45 days as the hormone being tested for (eCG) is not reliably present until that time frame commences.

thank you jos! i felt foolish asking, but if you do not ask, you do not learn. the mare should be at 42 days today (thank goodness we only have a one day window) and the kit ordered is the 38 day test.

thanks again!

Get her ultrasounded and checked for twins. It's a little late, but better late than never...!!!

thank you brenda and jos. yes, an ultrasound is definitely in order... i am still confounded over this pregnancy. funny how one can try and try and try to get a mare in foal, but the stallion knows when to get the job done. thanks again.
