I'm not sure what to do. Should I cut alfalfa completely out of the picture? Since he's still a youngster, I thought the higher protein and calcium in the alfalfa would be good for him while he's still developing and growing.
My riding instructor suggested mixing his alfalfa in with his other meals rather than to give him one meal of alfalfa and the rest of grass hay.
I guess it makes sense that the alfalfa might be too rich for his system, given that he comes from a place where he essentially lived on dry scrub. Could it be better to try a slow feeder so he's not hitting his system with large meals and then going for a few hours with nothing? I've given him probiotics, which may or may not have helped very much. Like I said, he seems to get better and then it will hit again.
