We have a clydie mare who when we tried to inseminate her ran into a peculiar problem. Her cervix felt like she wasn't even in season in that it wasn't open, very tight but also poking out felt like the end of a sausage... the little knobbly bit about the size of the end of your thumb.
This mare has never conceived naturally (no wonder) so we had her ultra sounded to see if she was retaining fluid, if the ovaries were ok... that kind of thing and she got a clean bill of health there so we preceded with AI only to feel that weird cervix...
Have you any ideas or clues as to what that may be?

It would be hard to make accurate suggestions in the absence of actually being able to feel the cervix, but possibilities include:
  • The mare was not truly in estrus;
  • there are fibrotic changes to the cervix (more likely if she is an older maiden);
  • There is damage to the cervix from prior foalings (you don't mention if she has got pregnant by AI);
  • There is a congenital abnormality.
Sorry not to be of much assistance beyond that!

HI Jos, thanks thats a great help actually.
The mare has NEVER foaled nor conceived via AI, I would lean towards your suggestion of fibrotic changes perhaps... however she never conceived running with a stallion in her younger years either BUT in saying that I believe the stallion she was paddocked with back then was really old and not much chop on the viable semen front.
It could be that she doesn't come on properly?? We have had mares like this in the past so gave them PG and TA DAH! they came in properly and fell straight in foal.

Would a congenital abnormality show up easily on a scan if she was checked when in estrus?

Hi Again, as Dad is the AI tech round here, I asked him again what exactly it felt like and he said it felt just like a closed / tight cervix.
To bring Bonny in as we hadnt seen her show we gave her the two separate doses of 0.2mls of PG. It brought her in sorta kinda in that she came on for a very short amount of time only, a matter of days
Maybe a full PG dose would be worth a shot?
I can line it up so that its timed with our repro vets visit?

One of my mares, a Section B Welsh was live covered when she was 9yrs.(before I got her) but did not get in foal. I bred her when she was 11yrs by AI, not sure if you would concider her a maiden since she was bred earlier? When I insemenated her, her cervix felt like it had Saran Wrap over the opening and it was kind of firm at first but it seemed to relax some after a little massaging. I was able to gently wiggle my finger in the opening. She was palpated, had a large soft folical but I don't remember the numbers and was teasing in to the stallion. I insemenated her only once and she did get in foal. But it was wierd how it felt like it had plastic wrap over the opening even when she softened up. Oh forgot to add, her cervix was on the bottom and was about 1 1/2 - 2" long, if it matters. It seems that they are all different and you only know you did everything right when they are checked in foal. I hope you get your mare in foal.

Without ultrasounding or running a progesterone assay, you really aren't going to have a good indication of what is going on relative to the cycle. It is quite possible that the mare is a silent estrus mare (check the link for an article).

As far as giving Prostaglandin F and not seeing anticipated results, there are multiple reasons why that might happen - see our article on prostaglandin use to read about that. A dose is either going to work or not, so if the reduced dose worked in that manner, then a full dose would have had the same effect, with all of the possible sweating and cramping side-effects as well.

Thanks Jos. Somehow we managed to get Viv (our repro guy) to come along tomorrow, I will put the mare in the crush and get him to have a good investigation, I will post his finding here as I guess they may also be of interest or help to others perhaps sometime.

Is there anything in particular you would suggest me asking him?

Unfortunately I am away from the office, so did not get this until just now, so this may be too late. I would however recommend what the vet is almost certainly going to do anyway, which is a standard breeding soundness examination.

HI Jos, thanks for getting back to me. Well the vet has pretty much no idea what the issue is, everything looks like it should, she is putting up good follicles, nothing is inflamed, the uterus is smooth and healthy... her cervix just doesn't seem to open

This is a classic "older maiden mare" (follow that link for a pertinent article). The chances are good that you are feeling a fibrotic cervix. Use of manual cervical manipulation, possibly coupled with estrogens and a topically treated PGE1 cream (Mysoprostol) all during the estrus during which she is bred may assist.

Thanks Jos, Viv said she had a 3 . something (just cant remember) maybe a 3.4 coming along nicely so he said he would PG her as then we KNOW when to be checking her due to the fact she doesn't show well if at all mostly. This was last Tuesday (seven days ago) she started to show "interest" on day three but nothing happening yet re cervic and still yesterday only a slight dimple could be felt and no where to put the pipette... will try her again today to see whats going on.
Vet said everything looks good, she has good tone ect ect and that its just a matter of "manually stimulating the cervix" which he explained in detail... still I think Bonnie may have given her cervix away or left it somewhere

Bear in mind that giving Prostaglandin F in the face of a large follicle (and >3 cm is large) can result in a rapid onset of estrus and ovulation - as little as 24 hours. Consequently, your mare may have already ovulated and gone out of heat by the time she was checked, which would also result in her cervix being closed.
