They are extremely palatable to horses and are easy to chew, even for older equines whose teeth may not be in perfect condition. They are more easily digested in comparison with heavier whole grains like wheat and corn. Oats are somewhat less susceptible to mold than corn or wheat, and unprocessed oats retain their quality well when properly stored. Shelf life is reduced after oats have been processed. Starch content of oats ranges from 43 to 61%, averaging around 53%.

Thus, oats have developed a reputation as a “safe” grain for horses...Read more here:
