Livestock Uses of Corn

Collectively, beef, poultry, pork and dairy producers represent corn
growers' No. 1 customer - consuming 5.6 billion bushels of corn
annually. Corn used directly as feed for domestic livestock represents
57 percent of all of the corn grown in the United States.

In 2003, beef cattle were fed more than 1.4 billion bushels of corn.
Hogs consumed 1.1 billion bushels.
Poultry another 1.3 billion bushels.
As a primary livestock feed source, corn is a key link in the meat
production chain. More than half of the U.S. corn crop puts meat on
America's dinner table. A bushel of corn fed to livestock produces 5.6
pounds of retail beef, 13 pounds of retail pork, 19.6 pounds of chicken
or 28 pounds of catfish.

Furthermore, most corn sold to other countries also is used to feed
livestock. In fact, 80 percent of corn raised in the United States is
fed to animals around the world
