AUSTIN -- For the week ending Feb. 19, feeder cattle auction prices were steady to $10 higher per hundredweight with tight supplies, higher fed cattle markets and renewed demand following the winter storms earlier in the month. Fed cattle were up sharply as processors sought to line up supplies in anticipation of higher prices later in the spring. Cotton prices continued to rise because of the tight supplies and strong demand. New export sales to Mexico helped support corn prices. . . .
