The USDA monthly Cattle on Feed report for August showed the number of cattle in feedlots was 10.656 million head, unchanged from pre-report estimates. July cattle placements were 1.922 million head, lower than last year and estimates. Marketings were 1.913 million head, slightly lower than last year but below estimates. Feedlot inventories are expected to remain below year-ago levels through the remainder of 2012 due to tighter supplies and high feed prices.
