Please watch how your horse sheds out this spring. Your horse could be developing metabolic syndrome and if so, they often get an extra wooly coat that seems to take forever to shed out. Horses with early metabolic syndrome can either get thick over the neck/mane area and have fat deposits sometimes looking like a lumpy butt OR some horses start dropping weight and have a big belly. Protein is necessary to build muscle regardless of what’s going on, but if your horse has metabolic syndrome you need a low starch feed…no sweet feed ever. I had a gelding that dropped weight very quickly and we had a double problem…metabolic syndrome and ulcers.
