AUSTIN -- For the week ending Feb. 5, feeder cattle auction price trends were mixed, mostly $3 lower to $3 higher per hundredweight with a few to $9 lower and receipts late in the week limited by wintry weather. Fed cattle prices were $2 higher. Cotton and grain prices were higher on continued strong global demand and tight supplies. Wheat had an added boost from concerns that extremely cold weather on the Plains would damage the crop. . . .
