My horse has just an apple and some carrots in summer as a feed when if is not worked a he is a fatty, and has them in his feed in winter - he loves them but if he has them in his feed he does not get them as treats
mine get apples and carrots every day. they also get pears, plums, nectarines, peaches, mango, kiwi fruit, bananas, parsnips, turnips and swede as and when i buy them. and they eat the blackberries that grow in the field.
