Beef, it's what's for dinner thanks to National Beef Packing Co. (NBPC). One of the biggest US beef processors, it produces name brand boxed, case-ready, portion-controlled, and other fresh and frozen beef products for 900-plus domestic and export markets. The company offers Naturewell Natural Beef and NatureSource brand beef, marketed as US-raised, corn and pasture grass-fed Angus cattle, free of antibiotics or added hormones. National Carriers, a 1,200-unit refrigerated trucking subsidiary, transports the meaty lineup within the US. Holding company Leucadia owns about a 79% stake in NBPC and U.S. Premium Beef, which markets beef through NBPC.
