We’ve found that with most of our mares - by day three after the 2nd dose they are usually ready to breed with a 5 follicle and A cervix. So watch your timing on this if you are shipping semen. We use mostly frozen so it’s not a problem if they go fast.

That’s one thing that has me the most worried! My vet recommended giving it Friday and I was worried that they would be close to ready by Sunday/Monday and then wouldn’t have enough time to give the S/O notice for shipping the semen (chilled)! I’m a little more optimistic right now as I just gave the second dose, and with you saying about three days has been your number, we should hopefully be in okay shape! I am getting them to the vet’s at 9 a.m. Monday and are ultrasounding them ASAP, and all three S/O are aware of my Lutalyse plan, etc., so know to be expecting a call quickly if things are progressing like they should (and also if they aren’t). Two are maiden and one has had three foals before but only been bred live cover, so it should be an interesting season:lol:
Average time from time prostaglandin is given to ovulation is 9.5 days. However, if the mare has a mid-cycle follicle, she can literally ovulate in less than 24 hours. So, before giving prostaglandin it is strongly suggested that the mare be checked to insure there is no mid-cycle follicle.
Hope that helps!

Holy wows! Haha I definitely am a newbie at this and wish I woulda asked that question first, too! Well, if they do ovulate early and we miss this cycle, that’s okay…we’ll just hit it on the next cycle then:lol: Thanks for the information on that! I will be sure to keep that for future reference!

Have you had success using the ‘cycling dose’ to get rid of a hemorrhagic follicle?
I have a young mare with a stubborn one that will not go away. Wondering if I need to break out the big dose for her. Yuck.[/QUOTE]
I have a mare with the same problem since last fall. If you find a solution, please let me know. Mine is currently undergoing the P&E method, and it appears to be failing.
Kathy - we’ve never had a mare go that long from the 2 shots to being ready to breed. The longest was 6 days. In a couple cases we had nothing at day 3 and then day 4 or 5 we had a follicle that was coming on very fast.
I think if there is no follicle that is already developing, it depends on what is normal for that mare. One of my mares progresses from a 2.5 to a 4.5 and soft in about 36 hours on a regular cycle for her.

I used to be skeptical of the time frame. But I always check the mares before administering the prostaglandin. And, when there has been no follicle larger than a 25 mm, the mares have almost always gone 9 days without fail. Occasionally, I’ll get one to go more quickly, but usually it’s only by a couple days. If the mares have a larger follicle when checked, I don’t bother administering prostaglandin. Funny as the mare we just bred to Red Wine went 9 days exactly, and that included using hCG.
With that said, we do a large number of mares every year and we “do” check before giving prostaglandin, so perhaps we just have a better idea of exactly what’s going on. I know many (most?) breeders give prostaglandin to have some time line as to where there mares might be as most mare owners don’t have stallions hanging around to assist in telling them <smile>.

Hit the nail on the head with that one! I don’t even have so much as a gelding around to try and “man up” to the job!:lol: Only one of my four mares shows her heat cycle. That particular mare is not on my property and is pastured with a gelding. My other three ladies are all I have at my house and have never shown signs of cycling:)
We do track cycles very closely on all the mares and keep rather detailed records. We also always palpate before giving the prostin. Guess we just have mares that go fast!
My mare is going through her 2nd bought of a hemorrhagic follicle. The first one regressed fairly quickly after administration of Estrumate. We had her one Regu-mate afterwards for 30 days. Within 14 days after stopping the Regu-mate she developed another one. This time however she seems to be going through occurrences of high fever increased heart rate due to pain every other 48 hours… Shot was given 8/1/2019 high fever on 8/4/2019 and 8/6/2019. Is this normal?
Kathy is long gone from this forum but they do have a FB page by the same name if you want to ask there. What does your vet say?
THIS…a reduced dose over two days is kinder, safer…and just as effective!
