Pepper is a 14 year old mostly foundation Quarter Horse mare. She's 15.1hh and has a lovely personality. Recently, I figured out (with much speculation and much help from forum members) that she has EPSM.
Purchased for $500, Pepper came to us with terrible teeth, terrible body condition, and terrible burrs in her mane and tail (these were more heinous to brush out than anything else). Her EPSM symptoms were interpreted as general laziness and mysterious lameness for about one and a half years, by vets and farriers alike. EPSM was never even considered. Pepper is on 10 acres of pasture 24/7. Her list of symptoms were:
- Strange lameness/stilted gait that seemed to come from nowhere, disappearing some days and being terrible others.
- Reluctance to trot or increase above a leisurely walk. When she did trot, she limped terribly.
- Reluctance to stretch or yield her hind
- Atrophy on her back and hind
- Reluctance to cooperate with the farrier
This fall, after a bad drought this summer and the grass shriveling up in August, to remain shriveled the rest of the year, these symptoms disappeared. Pepper was a new horse. I attributed it to farrier work and a pair of shoes.
This winter, due to the cold snap, I figured I'd feed the horses sweet feed to get their supplements and as a treat. After two weeks of sweet feed, Pepper's symptoms escalated to:
- Kicking her right hind leg up, randomly, at nothing. I thought it was due to the leg straps of her blanket, but she did not stop when the blanket was removed.
- Extremely stilted gate, especially on the hind
- Wobbling
- Arching her back and "tucking up" her belly
- Reluctance to move
- Cocking her hind foot "at rest" constantly, even while eating
- Camping her front legs under
- Standing with her hind feet extremely close together
- Depression
This thread is to compare photos and monitor improvement.
Pepper's new diet is:
1. Triple Crown No Starch
2. Rice Bran
3. Canola Oil (Cocosoya oil ordered today, we'll see when that arrives; oil and the rest of the following were fed to her pre-diet)
4. MSM
5. SmartMuscle
6. Grand Hoof Pellets
She hates it all. Hopefully the cocosoya will be good.
The following photos are day one of no sweet feed. They are in consecutive order.
