Twin ovulators do so habitually, so will regularly do the same thing over and over. Why is he terminating the whole pregnancy, rather than pinching one of the twins?
Although rare, horses can produce twins from a single fertilisation. However, in this case I assume your mare is double...
Glad you could answer the colour question TrueColours, thank you! :)
With regard to the extender comment, I just wanted to say that I do not believe this is the case. In 1994 Kotilainen et al performed a study looking at inflammation and semen type. They concluded that:
1) The components...
This could be a sign that there is some infection present - vaginitis, or something deeper/nastier, or it could be nothing or might be something unrelated to the pregnancy... but it's not possible for anyone here to diagnose via the forum, so if you are concerned, get your vet to check! Waiting...
Actually the extender does not cause any additional reaction (except in a very tiny minority of cases where the mare is sensitive to an antibiotic in the extender).
Mares in a natural cover scenario are exposed to the stallion, and therefore produce their own oxytocin - which causes the...
Uterine fluid is a natural response to insemination, but left unchecked those mares with delayed uterine clearance (DUC) have a very low chance of pregnancy. However, giving you a 50/50 chance estimate is probably rather unfair. Lavages like that may help, but it depends on the pattern of her...
He won't jump a dummy? I bet we could get him on the dummy, or ground collecting.
In the meantime, it looks like I may be down in Cornwall again this weekend at some point. Otherwise try Mel Hannah at Trenerth, or James Lukas - haven't used James, but I know he does work in that area.
Good...
And on top of that, I'm fairly sure that the stallion didn't even ejaculate if you watch the video closely! Pregnancy rates aren't going to be great if they keep doing that.. terrible, terrible, terrible.
OK... So I would look at the following:
1) Does the AI'ing vet know what they are doing? Are they truly experienced and successful at inseminating with frozen semen?
2) Is the semen proven?
3) Is she suitable? Ideally she should be younger than 14 and be reproductively sound, or she...
A mare cannot be teased into season. Her cycle is independent of stallions or geldings around her... otherwise how could a mare in a wild harem ever maintain a pregnancy?
The worry is that some geldings can achieve erections, and if he penetrated the cervix then that would cause the foal to...
Read Jos' article, rather appropriately entitled: I gave my mare prostaglandin but it didn't work!

This was quoted on another thread the other day, and is a super article - well worth a read!
In a normal delivery, the placenta ruptures and the amnion (white membrane) presents at the vulva.
In a red bag delivery, the placenta separates from the uterus prematurely and doesn't rupture. Therefore a red, velvety membrane presents instead.
The premature separation vastly reduces, or even...
