I was reading in an old veterinary book from 1989 that if a good amount of semen/fluids spill out of the mare when the stallion dismounts, then the cover was no good, and the breeding should be repeated in an hour....I have heard differently from others, and think the opinions in the book are simply outdated...

But.. The stallion that I'm trying to breed my mare to dumps quite a bit on the ground when he pulls out of my mare. He seems to get in there really good, and stays up on the mare to rest for several long seconds after seemingly ejaculating. I'm just wondering if I should be concerned that he is not depositing the semen properly into the cervix or not...

Also, he was mushroomed when he pulled out after the first cover, but when we bred them again two days later, he wasn't mushroomed when he pulled out, although he had definitely ejaculated. Should I be concerned about this? It was a little swollen, but not anything like it should have been.

There are 3 portions to an ejaculate - pre-ejaculate, the clear fluid one sees dripping prior to breeding; sperm-rich fraction, which is about the first three ejaculatory spurts and contains most of the sperm; and the tail-fraction of the ejaculate, which consists of the secondary sex gland secretions including seminal plasma and gel fraction (if there is any).

It is typically the tail-fraction of the ejaculate one sees dripping out of the mare if anything is seen. During breeding, the penis is introduced into and in some case through the cervix into the uterus at the time of ejaculation, so it is only the very end part of the ejaculate (the tail-fraction) that drips out as the stallion dismounts.

The only exception might be if there was a very small stallion and a very large mare involved. In that case, try and equalize the heights.

As long as the stallion ejaculated, there is no reason to be concerned about a lack of glans engorgement at the time of the dismount.

Thanks. I was sitting there reading the veterinary manual and thinking about how stupid it sounded. I guess that it goes to show how much ideas about breeding have changed in 20 years. Everything else about the process was text book. He is a great teaser and a gentleman. I guess I was just wondering, because when I have been present at hand-breedings in the past, I've never seen such a large volume come out of the mare.

In the old days vets were advise to pull the placental remains from the mare after foaling, subsequent science has modified that position to leave intact and promote natural expulsion to complete stage 3 labour with oxytocin.
