Unusually strong winter season before laminitis - any relationship?
|
Carly
About 10 or so days before Quest's laminitis started, she had an unusually strong season. Aside from it being out of season (winter, cold), it was strange as it was very intense. The gelding she shared with even mounted her, and she kept pestering him, backing into him. She is not particularly mare-ish normally, and has much less intense seasons than other mares.
I'm wondering if this may have anything to do with the laminitis attack? Whether it's a sign of her hormones being all out of balance, or if high insulin can impact the breeding hormones? She seems to be in season again now, and very frustrated being on box rest, standing by the window staring and nickering at her gelding friend outside. I found her hay feeder strewn all over her stable and she was sweating and breathing fast, but she'd also refused her food with pain relief. Her crest seems to have gone very hard again, but I don't know if that's just because of her alert and tense posture. -- Carly Butler Nottinghamshire, UK, 2020 https://ecir.groups.io/g/CaseHistory/files/Carly%20and%20Quest https://ecir.groups.io/g/CaseHistory/album?id=282557 |

How far apart were these cycles and how long did they last?

She had a season 12th November, the day she returned from vet (with arthramid and tildren given). I wasn't sure if she fully came out of it as she remained friendly with the gelding.
She was very strongly in season on 1st December and the gelding mounted her 3rd December. It carried on another 3-4 days I think. 12th Dec, noticed pulses so off grass 14th Dec Laminitis. She'd also had grass glands come up - which she has never had before. -- Carly Butler Nottinghamshire, UK, 2020 https://ecir.groups.io/g/CaseHistory/files/Carly%20and%20Quest https://ecir.groups.io/g/CaseHistory/album?id=282557 |

I don't think the grass glands (parotid salivary glands) are related but from your description I would be suspicious of an IR-ovarian syndrome, known as polycystic ovarian syndrome in women. Go here https://www.ecirhorse.org/proceedings-2015.php and download by presentation on ovarian abnormalities. Send it to your vet. You could either have a work up done or ask your vet if you can try a week or two of estradiol as a diagnostic test. The response to estrogen is pretty dramatic if this is the issue and it won't hurt her if it's not.

That's interesting, thank you! I'll send the information to my vet. A lot of the features are consistent with her history/presentation.

We can't get the LH or FSH done here anymore but progesterone could be of value if your vet wants to investigate it, and ovarian ultrasound. It doesn't happen to every mare with EMS but the timing of crest hardening and laminitis close to showing estrus is typical.
