Retention of the placenta is very common post-foaling in Draft (heavy) horse breeds. They also seem more likely to develop laminitis if expulsion of the placenta is delayed. Oxytocin after foaling is an effective way of inducing placental expulsion. Many Draft horse owners, tie a damp towel to the hanging placenta if it has not come away pretty quickly after foaling. If that doesn't work, then Oxytocin is given. Obviously preferably given by a vet but if a vet is not available for whatever reason, then a knowledgeable breeder can give it.
My daughter, who owns all our horses, has never had a problem yet with a retained placenta and her vet is always close by, but in an emergency, she would probably have to give Oxy.
The list I showed here, was put together by members of my forum. Obviously few would have all the items on hand and it was purely a list of possible items one would/should have on hand during foaling season.
We personally never bother a mare while foaling and wouldn't become involved unless there was an obvious problem. We do bring them in to the foaling stall though, a few weeks before their due date. It has an outside area with 6' stallion fencing, since we have wild animals about.
We don't like to leave our horses out in the paddocks to foal if at all possible. Nobody wants to search around for a placenta in the dark, if a mare foals at night, or have to help a mare if needed during foaling, far away from the barn.
The mares are shut in the foaling stall at night with a camera to be watched from the house.
My daughter doesn't allow all and sundry to come in and watch births. We really like to leave mares alone to get on with it quietly. Most usually, my daughter is the only one in attendance if needed and not in the stall with the mare. Last year however, she did allow my eldest granddaughter to view her first equine birth.
Okay, interesting. I didn't know draft crosses were more inclined to retain a placenta. I actually DO keep oxy in the house, for my dogs, my foundation bitch had an enormous litter the last time around and the vet advised it, although in the end I never used it, for my dogs a dose of calcium usually does the trick to supplement contractions.
Many of the things on your list I actually have on hand standard at any rate, again for whelping puppies. There are a few specific items I don't (such as an ob shoulder glove, a colostrometer, and the vitaflex foal response). I have Probios, assuming it's the same thing I give my goats? That's the name brand, anyways, it's just probiotic bacteria? And I have suture wire instead of fishing line. Will the colostrometer be necessary when this is not a maiden mare? She was definitely an over-producer with her last colt.
tealamutt ~ yes I am going to go ahead and have the vet do the ultrasound, I'll be calling for that tomorrow. I unfortunately do not have cameras in the barn (wish I did!) I've been getting up and checking Freyja at night, but only once during the night as so far I really don't think it's going to be that soon. I expect she'll wait until I'm not around, no matter what I do anyways. Goodness me I'm glad I won't have to go through this again! Dogs are so nice and predictable with giving birth, you just take their temp and it doesn't lie
I probably wouldn't dose the mare myself at any rate, but out of curiousity how would I calculate dosage?
You know, that's what I love about this forum. I learn new things all the time.
