The August CME feeder cattle contract gained 3.275 cents to 233.95 cents per pound, rising above its 40-day moving average. The contract closed off its session peak of 235.15 cents after facing resistance as it neared its 30-day moving average.

CME's benchmark August live cattle contract settled down 0.375 cent at 170.775 cents per pound, settling below its 20-day moving average.

CME July hogs fell 0.575 cent to 91.275 cents per pound. Most-active August hogs dipped 0.3 cent to close at 89.675 cents a pound.
