I have a 9 year old Registered Paint. He has heaves which are under control. He slightly coliked on me about a month ago, since then he has dropped weight on his rump considerably. I am not sure why, but he has been wormed regularly and doesn't seem to be having any other weight issues except for a little in his belly area that we noticed. I have since put him on a Textured 12-10 sweet feed and increased the amount. If anyone has any suggestions on a supplement or other grain or additional grain I could give him please let me know. He gets 5 flakes of 2nd cut hay every day.
