In animal feeding, steam flaked grains are used to improve feed efficiency and increase meat and milk production. Whole grains (corn, barley, wheat, rye) are conditioned with live steam to increase the temperature and moisture level, then flaked between large diameter rolls. Flaking increases the surface area of the grain, and causes a percentage of the starch to be gelatinized. Both the feed form and increased levels of starch gelatinization improve the bio-availability of the energy and nutrients available in the grain.
