"Mexico is devoting an increasing amount of its agricultural production to sorghum to feed cattle and other livestock. Twenty-five years ago, livestock consumed less than 6 percent of Mexico’s grain. Today at least one-third of the grain produced in the country is being fed to livestock. This in a country where millions of people are chronically undernourished."
