In some way, pretty much all body parts are used by one animal or another to eat. You may think animals don't use their eyes to eat, but most have to see the food they are eating, so technically animals use their eyes to eat. Every body part I think of seems to be involved in eating one way or another. I've never thought of it that way before.
A horse's hooves are like your feet except harder. they use them the same way you use your feet: walking, running, jumping......
