Chicago Board of Trade corn futures slipped on Wednesday, following a pullback in crude oil prices and mounting concern over domestic demand for feed use, traders said.

But prices got some support on news that frosty temperatures are expected in the US Midwest on Saturday, which could threaten newly planted corn crops and developing soft red winter wheat.

CBOT most-active July corn settled at $3.14-1/4 a bushel on Wednesday, down 2-3/4 cents from Tuesday's settlement of $3.17 a bushel.
