Corn Facts

Corn price futures for the July 2021 contract increased from $4.68 per bushel in early January to $6.56 in the week ending April 30. The U.S. stock to use ratio is 9.2 percent and continuous questions related to U.S. corn acreage in 2021 means there is tremendous uncertainty regarding corn prices for the rest of this year.

Using projected corn prices, feeding costs of gain is expected to peak in the third quarter. However, each increase in corn price results in an increase in feeding cost.
