Have you had a vitamin/ mineral test done? Not the hair pulling, but the blood analysis? There are only a few labs (I think) that have the capability to do it. It is different from a blood chemistry panel. UNiversity of Michigan does mine. I had a horse that the vet could find nothing wrong with, did blood panels, fecal & urine tests, teeth checked, wormed, tubed more than once to force fluids and feed, antibiotics and everything I could throw at him.
Even had our water tested for contamination. Finally I begged to have him checked for toxins from possible contact with flood water, and a vitamin/ mineral panel was all they could really do. Turns out he was severely deficient in some areas and required injected supplementation. 2 days after his first shot, he had his appetite back, after about 6 weeks, he had packed on the pounds to be up to a 3.5/4 on the scale.
The test is cheap, I think it cost me less than $50 with shipping. As long as your horse has normal chem panels, I would say that organ failure isn't *yet* the cause.
