My retired event/dressage horse will be 36 in January and he impresses the vets and all that know him with his amazing prescence. He has lost some teeth and cannot eat hay nor gain enough nutrients from grass. Therefore, I suggest the following: Add rice bran to the grain which should have very wrm water added to it so that mastication is easier. Add rice bran to the beet pulp(softened with the same temp. of water). Allow your horse to eat at his/her liesure; these geriatric souls need time without pressure to enable them to enjoy their mealtime!
