 Still, that interest seems to be light, at least partially due to concerns that consumer demand is slowing down, and there is always the chance those buyers could wait until after the USDA's cattle on feeder port Friday afternoon to complete this week's activity. Boxed beef was lower with light movement. Choice was down $1.00 and a dime at $3.1816, and select beef was $3.15 lower at $2.9844. The estimated cattle slaughter of 121,000 head was down 1,000 on the week and just over 1,000 on the year.
