World trade in feed grains (barley, corn, rye, oats, and other cereals, n.e.s.) more than tripled from 1962-85, while the number of countries participating in world trade increased 85 percent. Feed grain consumption has increased faster than production in most countries, so more countries entered world trade for their feed needs, thereby increasing the volume and changing the patterns of world trade in feed grains. This report is based primarily on world trade data of the United Nations and foreign trade statistics of countries not reporting to the United Nations.
