AUSTIN -- For the week ending Jan. 1, feeder cattle auction prices are not available as all locations covered by Market News were closed for the holidays. The fed cattle market was sharply higher following increases in wholesale beef prices and as processors rebuild post-holiday supplies. Cotton prices were sharply lower after China raised interest rates and set a lower cotton import quota for 2011. Corn and grain sorghum were higher amid ongoing concerns that dry weather in South America will reduce already tight global supplies. Wheat was higher because of the continued dry weather in the major growing areas of the U.S. Central Plains. . . .
