U.S. lean-hog futures are expected to open higher after setting another all-time high in electronic trade. Pork prices continue to set new records daily, including Wednesday.

Meanwhile, cash-hog prices are expected to be firm as hot weather that has limited weights support the market. Gains could be limited by outside markets, including a stronger dollar and sharply lower equities.

CME August lean hogs were recently up 0.525c at $1.05175/pound.
