Elevated beef values have supported cattle futures for months, and traders now are assessing whether high prices could begin weighing on beef demand at the end of the summer outdoor grilling season. Losses, however, were limited as cash cattle prices remained at a premium to futures, analysts said. Packer bids at midweek this week suggested cash cattle prices could be at least steady with last week. Beef packer margins remained in the black despite tight cattle supplies and firm cattle prices as beef values hovered near multi-year highs. Feeder cattle futures followed live cattle lower, with the October contract ending the day down 2.200 cents at 361.500 cents per pound.
