My 3 1/2yr maiden App mare has shown regular seasons until mid-Spring. She showed once to the stallion at the beginning of Spring and then not again. In fact, that season was so strong I had to move her to another part of the farm as she was determined to get to him and he to her.

I am going to get the vet out to check her if she doesn't cycle soon, but just wondered why a mare could just suddenly stop showing. Are there any other reasons apart from pregnancy which might be a reason? No, she was not covered:-)

If you have moved her completely away from the stallion that may be the reason. A few of my mares wont show unless there is a stallion nearby then they cycle like clock work

Check out the article about silent heat mares on this web site.

Thanks Jos:-) She has shown a heat regularly throughout each breeding season since she was a yearling. For it to suddenly stop two months ago is really weird. Usually the sign of a pregnancy but she can't be in foal as she hasn't been covered. From what I understand in the article silent heats are not something that just happen are they?

Hi Jenni, the stallion runs alongside the mares and all are separated by both post and rail and electric fencing. I remove her from the stallion during her heat as I do not want to temp fate and have an accident. If she is not in season she is alongside the stallion. I wouldn't usually expect a mare to show a season if there isn't a stallion or gelding nearby;) At least, I haven't experienced this in my 20yrs of owning and breeding the occasional foal.

Some mares will show a cycle wether anyone else is around or not some must be teased to get to show and others the mere presence of a nearbye stallion will make them show

I'm sure it does, but not in my herd.

Horses are sentient beings, so environmental variables can have an impact. If the stallion to whom she has shown in the past "says" something unpleasant to her, she may not show to him in the future - so yes, cessation of estrus behaviours can indeed stop and start.

Mares can and do show to other than a stallion. I've even seen mares displaying estrus to inanimate objects and humans, although that is rare than other horses! :-)

I wondered about the former, if perhaps she'd got too close to the electric fence and been burned and it had perhaps stopped her physically showing to him. She had been showing such strong seasons though.

I should have clarified it by saying that my mares do not show to anything other than the stallion and my problem anyway is that she is not showing anymore.

An update on the mare is she started showing to the stallion yesterday afternoon. She is only just starting to come into season again.

I'm finding it odd that she didn't show to the stallion for two cycles, and now starts showing again.

The vet is coming out in the next couple of weeks to u/s anyway, but I'm mighty relieved that she seems to be on track again after having had my fair share of problem breeders in the past.

Other than the above noted reason (sentient beings), there is also the possibility that the mare had an anovulatory hemorrhagic follicle which delayed estrus - something that is slightly more common at the very beginning and end of the physiological breeding season, and which could take 60-90 days to resolve (making the timing about right).

Thanks very much Jos. Could she have still come into season once at the beginning of Spring like she did (ie just over 2 months ago) and then not again for two seasons and again now? This mare has really flummoxed me!

If you read the article about AHF's that I gave the link for, you will see that some do not produce luteal tissue, and consequently the mare will not return to estrus until the AHF has resolved by itself - typically 60-90 days. That is therefore one possibility.

As you now indicate "spring" as being just over 2 months ago, I presume you are in the southern hemisphere, and that opens another normal possibility up - that the mare is still transitional. Talk to your vet about it, and they will [probably] be able to explain it more in detail.
