AUSTIN -- For the week ending July 16, feeder cattle prices at Texas auctions were mixed, with sales early in the week mostly $3 to $6 higher per hundredweight and later-week sales mostly steady to $7 lower. Declines in fed cattle and futures markets contributed to the decrease. Fed cattle prices were $4 lower in spite of modestly higher wholesale beef values. Cotton cash prices declined because of continued weak exports and concerns about future demand. Corn and grain sorghum prices were higher amid forecasts for much hotter weather in the Midwest just as corn is beginning to pollinate. Wheat prices increased following a favorable supply and demand report. . . .
