I have two horses that eat the whole banana. Some love the peel, some don’t. Just depends.
Peel it. You can give apples, peers, grapes, bananas and berries in reasonable quantitied. No tomatos, no kiwis. Peaches and apricots, without the kernel.
Depends on what the horse likes I guess lol
My boy loves bananas, I peel them and give hem to him ☺️
