Corn (Maize) is a common and usually economical cereal grain to feed horses. It is also highly palatable and has a high dietary energy content. However, corn is also high in starch, lower in fiber and crude protein level and quality than other cereal grain choices.
Corn can be fed whole, cracked, flaked or rolled. Ground corn should not be fed to horses, as it passes through the small intestines rapidly which causes fermentation in the hindgut, increasing the risk of colic and founder.
