The elephant staff also visually inspects the hay before feeding it for things like odor, foreign material, sun damage, and maturity. The remainder of the elephants’ diet is made up of produce, beet pulp, Vitamin E, browse, and supplements. Produce: The elephants receive carrots, sweet potatoes, oranges and apples as part of their daily diet. They also eat novel produce such as pineapple, onions or papaya, ordered weekly as enrichment. Just like people, they have favorite fruits and vegetables and tend to prefer the sweet fruits to the green vegetables.
