Feeds that are low in fiber but high in digestible nutrients, including grains, consisting of by-products, and oilmeals.
A horse should not be fed a diet that consists only of concentrates and water, as the animal's digestive system also requires significant quantities of fiber or roughage. The customary source of roughage is hay.
Some common concentrates are barley, bran (made from wheat), commercially prepared rations (content varies), corn, cottonseed meal, linseed meal, oats, roasted soybeans, sorghum, soybean meal, sweet feed (a mixture of oats, corn, bran, pellets, and molasses), and wheat.
