This increase in exports reflects the expansion in ethanol production that occurred over this same period, rising from just under 4 billion gallons in 2005 to more than 14 billion gallons in 2014. While U.S. corn exports still exceed the volume of DDGS exported, these markets are linked because each ton of corn processed into ethanol produces just under a third of a ton of DDGS. Ethanol production accounted for 38 percent of U.S. corn use in 2014/15, while exports were less than 14 percent, but DDGS exports represent another way that U.S. corn production enters global markets.
