This has been the most frustrating breeding season! Background...All mares have been cultured clean, are of normal weight, & have all vaccinations. Mare# 1 is 14 years old had one foal when she was 3. Mare#2 is 12 years old and is maiden. I started in March with Regumating mares #1 & #2 for 15 days, then used Dinoprost IM and then inseminating mares when ready. As a matter of practice I always use Oxytocin 6 hours post breeding 1cc IM.
Mare#1 At 20 days was pregnant, great placement. Mare#2 At 20 days looked like she was absorbing. Rechecked Mare#2 at day 32 and wasn't preg. Upon vet's orders, I Dinoprosted again Mare#2 & AI when ready. Had vet out prior & after AI. Vet said looked like I got her on ovulation. Ultrasounded Mare #2 at 25 days - Pregnant, but not really sure if she would keep, edges not clear. Ultrasounded Mare #2 again at day 60 Not in Foal.
Now Mare#1 is rechecked at 60 days and its gone! So I Dinoprost her again, Ultrasound day prior to AI, Ultrasound day after AI, Oxytocin 6 hours post ovulation, Vet says I got her on ovulation. Preg check at 18 days , yes Preg, but looks small. Recheck at 53 OPEN. So if this is not frustrating enough here is my other mare...
Mare #3 ~ she had a foal this year, has always had foals easily for the last 3 years. I culture her at day 16 after foaling, all clear. I Dinoprost her on day 20 after foaling. She comes in and we AI on the 24th & 26th day after foaling. We preg Ultrasound checked her at 16, Yes in foal then at day 37 & 61 still in foal. I wanted to preg check at day 96 because of the loss of my other mares so I did and the vet says upon ultrasound the fetus looks small, but its still there. He said if he had only palped her he would say she was preg , but only around 45 days so he's concerned if she's trying to absorb. So we rechecked her at 114 days, yes still pregnant, but small and he thinks she's trying to absorb. Foal is still on the side of this mare and she is big. We're about ready to wean, as she 4 months old, but both eat well. This mare is a little thin, not bad . I have upped her hay and Equine Senior. I have just put her on 10cc Regumate a day. The vet is doubtful, but says perhapse the foal being at the side is taking the extra progesterone. WHAT DO I DO??? This is crazy. Any ideas? Could this mare just have a small fetus at this point, or ??? On the only positive note... I did AI another mare at the farm and on the 2nd try I did get her preg and she rechecked twice in foal at the latest being at 71 days strong & with heartbeat. Should I do anything with her? OK...long letter...lets see if we have any ideas???? For location we're in Minnesota, close to North Dakota. Mares are always in the barn, let out for exercise daily on a somewhat of a pasture/arena. I've been told a lot of mares are late absorbing in this area by other breeders, some are blaming "army worms"??? Don't know if this is true or not or are we just looking for ghosts that aren't there?

I had a mare when I would A.I her she wouldn't keep it. But when I live breed her she stay's with foal. Maybe that's it! Good Luck

Lori- This is a very frustrating situation. You have followed your mares carefully and have attempted to follow suggested protocols.

I would suggest that on mares #1 & #2 you keep them on Regumate for 120 days starting on day 5, post ovulation. It will be expensive, but you stand a better chance of maintaining a pregnancy. The protocol for Regumate is 90-120 days, considering the late absorption of your mare, I would go the entire 120.

How is mare #3 doing? Did the weaning and Regumate help any? Yes, you could have a small foal, but it would be a very small foal to be seen by ultrasound on day 96. The amount of growth could be followed in the first few months, by ultrasound. Usually, nearing day 60 it is difficult to get the pregnancy to fit on the screen. If the foal were growing at an expected rate, although small, all should be well. The fact that the pregnancy was estimated at 1/2 the expected size, is not promising. I hope that it is all working out for you.

Yes, that's what we are most likely going to do about the Regumate on the mares. The #3 Mare seems to be getting larger in the belly area, the weaning has helped her start to gain some weight back, probably wishful thinking though. I'm waiting till the middle of OCT and I will have the last Ultrasound done on her then that will tell the tale if we have or do not have a pregnancy. I'm not expecting much, but you never know. Hopefully next year will be better, thank you for your input.

Ok, here's the strange tale. We ultrasounded at 150 days and the mare is still pregnant, pregnancy looks dark with definite borders, but the size is about the size of a silver dollar. Shouldn't be this small though, not even this small. So I guess we wait and see. We removed foal from her side about a month ago and mare is slowly regaining weight. Vet thinks we'll lose this one becuase of size, but any ideas would be appreciated.
