Cattle futures closed slightly lower on the session yesterday after choppy and two-sided trade earlier in the day. Many traders remain concerned with weak demand indications after the East Coast storm may have disrupted barbeque and restaurant demand trends. In addition, packer demand for live inventory may be slower than normal this week with one less slaughter day in the schedule for next week. Short-term demand factors are still a concern for cattle, as the market tries to absorb the negative impact of Hurricane Irene on East Coast demand. Lost demand from large storms is normally not recaptured at a later time, and the decline in beef prices due to the slower moving pipeline might have a negative impact on cash prices over the near-term. Some traders feel it may take lower beef prices to move the extra supply left in the wake of the storms. Cash cattle traded at mostly $112.50 last week, and packers are bidding $110.00 this week with offers mostly at $113.00 to $116.00. Boxed beef cutout values were down 35 cents at midsession yesterday and closed $1.63 lower at $184.57. This was down from $187.11 the prior week, and is the lowest beef market since August 16th. The showlist is close to unchanged from last week so the market is leaning toward a slightly lower cash market over the next few sessions. The latest US Consumer Confidence readings were poor, which have added to increasingly negative demand concerns. The estimated cattle slaughter came in at 127,000 head yesterday. This brings the total for the week so far to 254,000 head, up from 252,000 head last week at this time but down from 258,000 head a year ago.
