Have you ever noticed a loss in hair color of an anhidrotic horse, or hoof problems. Also, sweat glands have tiny granules which respond to the stimulation of the catecholamines to produce the sweating effect. Studies show that it takes about 4 days to see an improvement on a special diet for anhidrosis. Generally, the horse will recover its appetite or respiration will fall to near normal. About a week later the animal may spontaneously start to sweat if the temperature and humidity are in the eighties.
Light training can start within a weeks of beginning to feed the special diet.
There are a large number of racehorses affected to some degree with anhidrosis. It looks as though this supplementmay neverget to market so that these horses can be helped. We all want to have scientific proof that products work before we spend our money, or our client's money on them. There ought to be more lenient rules for products which are actually feed supplements,butwhich theFDA classiSes as drugs. This would open the door to development ofmore specialized feed additives, which could benefit horses with vadous types of medical and physiological problems.
