The USDA said domestic corn stockpiles on March 1 totaled 7.745bil bu, eclipsing analysts' expectations for 7.628bil bu. That March 1 figure was 10.5% higher than stockpiles March’14, thanks in part to record corn production last year. The report suggested use of the grain by domestic livestock farmers in the last quarter also may have been lower than expected as producers substituted DDGS into feed for cattle and pigs. USDA predicted U.S. growers would seed 89.199mil acres with corn this year, down from 90.597mil in 2014, but higher than analysts' expectations for 88.684mil. USDA's projection for planted acres of corn "was a bit of a surprise". May Corn declined 18 1/4 cents, or 4.6%, to $3.76 1/4 a bushel.
