One of the horses at my new barn eats bananas whole with the peeling and all. He only likes them when they’re really ripe and a little mushy. Still kind of freaked me out to watch him eat it, LOL.
Mine will eat them with the peel on too. Heck, they will eat just the peel after I ate the banana.
A friend’s horse loved pickles, fries with ketchup and ice cubes that had been in soda or anything sweet.
My current mare adores jelly, plain and cinnamon doughnuts. She also eats all standard horse treats (apples, carrots, premade treats) and supplements. Weirdly, she wouldn’t eat peppermints when I first got her but a few years later she loves them. We haven’t been that adventurous yet but I’m pretty sure she’d enjoy most food items.
My old mare, on the other hand, would eat pretty much anything - she would even eat Bute tabs out of your hand if you gave her treats before and after. Harvest cheddar sun chips, bread, oranges, fruit loops, fruit rollups, Skittles, grapes, chocolate, soda, Propel, NutriGrain bars, Oreos… the list goes on. The only thing she hated? Alfalfa pellets.
The two donkeys taught the young mare to love bananas and oranges, and their peels. Halo oranges are preferred, followed by Mandarins and regular oranges last.
The young mare will also practically maul you for a handful of IPA beer. She’s the only beer drinker at our place, except for the humans.
