CME live and feeder cattle contracts rose due to commodity funds increasing their net long positions, driven by near-record cash cattle prices and a lack of herd rebuild. Lean hog futures also increased due to stronger pork cutout values and position squaring before the weekend and Christmas holiday. The U.S. Department of Agriculture's Cattle on Feed report showed a slight decrease in placements and marketing compared to the previous year, but placed and marketed numbers were roughly in line with expectations. The U.S. hog herd size remained stable from the previous year, and the U.S.-Mexico border's closure to cattle imports due to New World screwworm further restricts U.S. cattle supply, supporting futures.
