Hi @JB! Thanks for the reply!
Unfortunately, I board and can’t really play around with forage much (without it costing me a fortune). We wanted to do allergy testing (intradermal, not blood) for her asthma/EIPH/hives, but supply chain issues prevented that - vet doesn’t have enough of the allergens. So, absent knowing what she might be sensitive to, it would be darts at a wall adjusting her forage. I would buy alternative forage if I knew what she was sensitive to.
Nothing has changed in the hay of late. Same forage. Same supplier. Same batch… maybe mixed with a new batch.
She seems to be the only one reacting to something. Previously with her asthma/hives, other horses with sensitivities would also cough, so I had some indicator that it might be the hay. She’s isn’t coughing now and hasn’t had hives this year, and she the only one having ANY reaction whatsoever (nobody else has fecal water, diarrhea, hives or coughing)… so unless it is an allergy specific to her, not sure whether it is forage related. Her hay is soaked, not rinsed, if that makes a difference.
My mare previously had loose stools that resolved well on GUT for two years - more like regular diarrhea/cow patties. In the last month or so, now she has (usually) well-formed fecal balls with excess fecal water or (more occasionally) cow patties. Always, though, with excess fecal water. Her bedding is SOAKED under her poops and it splashes in the crossties. She also developed basically diaper rash as a result (since resolved with desitin). Oh! And she NEVER poops on the arena - I can count on my fingers the times she has in 2.5 years - but now it is a daily occurrence. Yesterday, she pooped in crossties, then in arena, then twice in the wash rack. Four times in about 2 hours.
I don’t want to go on a fishing expedition, nor do I want to pay a million dollars for supplements, but I also want to fix this.
