My horse mostly gets apples from fruit. When it's apple season in late summer and autumn, the whole herd gets a handful of apples with their daily grains or just so in the pastures, but they are always from local or personal orchards, with no chemicals used in the process of ripening. I watch out not to give overripe apples, though, as they can get a horse gasey.
He also gets rasberries, blackberries and blueberries, if I pick them in the forest myself or if he gets to munch on a rasberry bush (he LOVES that, leaves, branches and berries go down his throat instantly). However, I don't give him any fruits that are exotic to our country - watermelons, bananas, peaches and such, as I don't want him to ingest any chemicals that might have been used in growing and transporting this produce.
He also gets a variation of local vegetables, mainly beetroots, carrots, kohlrabi and such, in a moderate quantity, as a tasty addition to his everyday feed.
I have come a long way, to surrender my shadow to the shadow of my horse.
