The largest industry consuming corn is livestock and the livestock consuming the most corn is cows. Since corn and cattle are so dependent upon one another, the price of corn greatly affects the price of beef. The USDA and Economic Research Service estimate that it takes 7 pounds of corn to raise one pound of beef. That graph expresses in kilograms how much grain it takes to raise one pound of other meats.
The USDA explains that when corn prices raise as high as they have for an extended period of time, meat prices are greatly affected in a negative way. To see how inflated grain prices have effected meats and other food prices read this ERS report on food expenditures --->http://www.ers.usda.gov/briefing/cpifoodandexpenditures/
