    This is not my horse, but the horse that is next door to mine in the barn. I know hes older, I beleive she said in his 20's. His manure is so dark, almost black. She, (the BO) told me when the vet was out this week, he commented on the manure, saying it was too dark, didnt give her a reason that she recalled. I am just curious what would cause that and if its a sign of any problems going on inside??? Hes on the thin side too. Also, her vet said that it is VERY important for horses to have yeast in their diets to help with the digestive system. I never heard that before, but then again, i've never been so involved with equine nutrition till this past year when I got my horse back. :wink:

    Blood can cause dark manure like that. I would be seriously looking at cancer or ulcers or something of that nature.

    I also know when our boys were getting limited amounts of poor quality hay, they had dark manure, and it was somewhat hard. Now that they are on free choice good quality hay, their manure has lightened up and is the normal consistency, and there is A LOT more manure!! Woohoo!

    I can say the hay isn't that great. Also, the pasture is coming in, but slowly, so they were on round bales, those have been eaten down for the most part and the horses are mostly trying to consume the grass right now. I know this particular horse is on some oats and alfalfa pellets as well as a few other supplements.

    I would start with a half tube of Probios and the rest the next day, if no change then time to call the vet.

    I know this horse is on a daily probiotic right now. How effective it is, not sure. I honestly have never seen such dark manure.

    The Vet should perform a fecal occult blood test to determine if there is digested blood in the feces. I certainly second JB and Rio on the consideration for diagnosis based on the symptoms presented.

    The vet told her if his diarehha returns he will then perform blood tests to see whats going on. Apparently he had a horrible case of the runs for two weeks. She started him on the probiotic, power packed him, on the advice of the vet, and changed his feed. It stopped. but now the manure is black. I wouldn't doubt he has ulcers..She rescued him from starvation about 9 months ago.

    Oh my poor thing. I can pm you on a pharmacy (in the united states) that her Vet can contact about getting omeprazole paste to treat equine gastric ulcers, it is where my Vet sends out for it for his patients. Much less expensive than ulcerguard, same ingredients, about 200.00 for a thirty day treatment. My Vet does this for rescue horses. He is a saint.
