There are two categories that corn grown in the US is generally placed into. "Sweet" corn and "field" corn. The sweet variety is what you are used to eating. The field variety is used to feed animals, make alcohol, and in some commercially processed foods like breakfast cereals.
When distilling alcohol from corn the starches are used. If the remaining "distiller's grain" byproduct is fed to beef there is no loss in nutritional value. Cattle have a rumen, which removes the starch as waste anyway.
Field corn is one of the most important sources for feed. Cattle, hogs and even chickens use it.

The legs of the corn crib should be lashed with stove pipe to prevent rats and field mice from getting into the corn.
