AUSTIN -- For the week ending March 12, feeder cattle prices at Texas auctions were mostly $1 to $9 higher per hundredweight. Tight supplies and higher fed cattle continue to support the market. Fed cattle prices were sharply higher as wholesale beef values continued to increase. Cotton and grain prices declined on Thursday in response to the U.S. Department of Agriculture’s supply and demand report then dropped even more on Friday amid concerns about the earthquake and tsunami that hit Japan. Japan is a major importer of U.S. agricultural commodities and is the No.1 overseas buyer of U.S. corn and pork. . . .
