AUSTIN -- For the week ending Sept. 7, feeder cattle prices reported by Texas auctions were $4 lower to $3 higher per hundredweight (cwt) compared to the previous week. Texas direct feeder cattle sales were $1 to $3 higher. Fluctuating grain prices and the possibility this year’s corn crop might be smaller than previously predicted has introduced more uncertainty for feeder cattle buyers. This also has resulted in some instances of lower prices in spite of the shrinking supply. Fed cattle prices were steady. Wholesale beef prices were lower. Weekly beef export sales were down 24 percent from the previous week, but 17 percent higher than the prior four-week average. Cumulative sales for the year are down nearly 16 percent from last year. . . .
