AUSTIN -- For the week ending Sept. 14, feeder cattle prices reported by Texas auctions were $8 lower to $6 higher per hundredweight (cwt) compared to the previous week. Texas direct feeder cattle sales were steady and the Oklahoma City National Stockyards were mostly steady to $1 higher. Several locations noted significant discounts on unweaned calves compared to their weaned counterparts. Tight supplies continue to support feeder cattle prices, but volatile grain markets have created more uncertainty for feeder cattle buyers. Fed cattle prices were steady. Wholesale beef prices were lower. Weekly beef export sales were up six percent from last week and eight percent higher than the prior four-week average. Cumulative sales for the year are down 15.1 percent from this time a year ago. . . .
