We gave both Penny and Queen Prostagladin before breeding them last year. I believe both mares just sweated and acted a tad colicky, but no real issues whatsoever. Just wanted to throw that in

At least five days and preferably six. There must be a fully formed corpus luteum for prostaglandin to be effective. Any earlier than that and it's just not effective.

You literally "COLIC" the horse in many instances, some go down hard, some don't even bat an eye and get a bit grumpy for a few hours.

Only if you are using the archaic method of giving 1, 2 or 3 mls of prostaglandin. Research now has proven that giving 2 consecutive microdoses of prostaglandin (1/10th to 2/10th mls) over two days will have the same end results without the dramatic side effects. If your vet is still using the higher doses, he/she's not keeping up with the latest research. And, that's OLD research...at least 6 years old now.

With regards to breeding on the foal heat, research also shows that if the mare OVULATES at least 10 days post foaling, the conception rate is comparable to any other breeding cycle. However, if the mare is bred and ovualtes before that 10 day mark, there is a considerably higher incidence of early embryonic death.

Hope that helps!

Last vet that applied that and I gave it wasnt' my vet....haven't asked my own yet....

I was just assigned to pop the meds.

LOL

Okay so I have one mare on regumate which Wed will be the last dose. My question is the vet wanted to insert antibotics in her before we breed her. He said it would help the folicule stick better or something to that effect and I posted about it and someone gave me a link that it's not good to insert the meds so I'm confused on that too? Should I not or call a different vet or just try breeding her without the meds. He said too that if there was any infection it would wash it out as well.

Now tomorrow my other mare starts her foal heat 9 days from birth and from what I'm reading its really not healthy on her so I want to cut her cycle short so tell me exactly what I need to do. Are we going to Regumate her for 10 days and then breed her? So when would I start her regumate? I don't want a much later breeding date were running on a mid yr foal. Any suggestions would be helpful. My friend uses a shot that brings the mare in in 4 days does anyone know what shot that might be?

So I could breed her after the 10th day and if she takes it should be safe or should I be safe and just short cycle her. We are doing live cover. Is she more fert. on foal heat or short cycle? Thanks

Mares can and do ovulate in the face of progesterone. Indeed, it is essential for pregnancy maintenance! Using Regumate to try and target ovulation and get the mare to cycle "on schedule" while it may work, is not as reliable as using P&E (progesterone and Estradiol 17 beta)

My question is the vet wanted to insert antibotics in her before we breed her.

Then I'm assuming he's run a culture and cytology and identified the pathogen he wishes to treat? If not, he may very well be doing something that can CREATE a super infection.

He said it would help the folicule stick better or something to that effect

Rubbish. Using antibiotics are only effective if one is treating a pathogen. Otherwise, at the very least, you are throwing away money and at the very worst, may create problems.

and I posted about it and someone gave me a link that it's not good to insert the meds so I'm confused on that too? Should I not or call a different vet or just try breeding her without the meds. He said too that if there was any infection it would wash it out as well.

<sigh>...Your call. I'm not to contradict what your veterinarians doing, he's the doctor afterall. But, I would certainly educate myself and do what I believe is right for my mare...not what someone is necessarily dictating what needs to be done! You "do" have a voice in how your mare is treated.

Now tomorrow my other mare starts her foal heat 9 days from birth and from what I'm reading its really not healthy on her so I want to cut her cycle short so tell me exactly what I need to do.

As I noted in my previous post. Breeding on the foal heat is just fine, so long as she ovulates at least 10 days post foaling and there were no complications with teh foaling, no placentitis, no retained placentas, no dystocias, etc. Normal healthy foaling.

Are we going to Regumate her for 10 days and then breed her? So when would I start her regumate? I don't want a much later breeding date were running on a mid yr foal. Any suggestions would be helpful. My friend uses a shot that brings the mare in in 4 days does anyone know what shot that might be?

If you're going to short cycle her, allow her to go through her heat cycle. When she's no longer teasing, count 6 days and give a shot of prostaglandin. Using Regumate may very well be ineffective and expensive.

Hope that helps!

As most know here, I'm NOT a fan of live cover and on a foal heat, I definitely wouldn't do it. It's definitely a trainwreck looking for a place to happen and with a young foal in the middle of things, it can get really dicey, especially if the mare is protective of the foal. Short cycle the mare.

Okay I'm gonna short cycle her so she will be 9 days since birth tomorrow so I should keep teasing her? And when she doesn't tease as in squirt then I'm going to count 6 days then give the shot and then how many days after the shot do I breed her? So Regumate isn't as effective? It cost me like 58 bucks for 10 days and it may not work? The other is better your saying. Well I hope my mare takes. My vet didn't do anything other then Ultrasound her and said everything looked good. I was worried about infection but he said just a tad fluid on Uterus and that normal sometimes nothing to worry about. So he said we would insert the antibotics to make sure no infection and help folicole to stick so thats not right? I thinking I may just try breeding her 2 days after the regumate. I may consult a different vet and see what they say. I'm fixing to go check out your details on short course. Thank you!

Some excellent information, Equine Repro, and very good to know. Thanks.

[BettyBootsy]

Yes! Thank you!
