U.S. lean-hog futures were also mixed as traders weighed record pork prices and supportive fundamentals against broader concerns over the U.S. economy.

CME August hogs rose 0.7% to $1.038 a pound, while October hogs slid 0.32 cent, or 0.4% to 93.67 cents a pound.

Pork prices hit a record Monday for the fifth-straight session on strong export demand and tightening supplies. The USDA's pork carcass composite value, a measure of wholesale pork prices, rose 73 cents to $105.37 a hundred pounds, which is 5% higher than last week.

A prolonged summer heat has slowed the weight gains of slaughter-ready hogs, which has in turn tightened supplies as producers bring lighter animals to market.

"This incredible spike in temperatures across the Midwest and Iowa...has really stressed the animals," said Alton Calo, analyst at Steiner Consulting Group.

At the same time, China has said it will act aggressively to rein in spiralling food prices there, which has in turn supported prices of pork and corn.

Futures felt pressure from a broader market sell-off tied to legislation in Washington that will raise the U.S. debt ceiling. Some economists have said the package will weigh on the sputtering economic recovery in the U.S., while others have said the deficit reduction measures should have been stronger.

Cash hog prices were reported steady to higher on buying interest by several processors needing additional loads to fill this week's slaughter schedules. Lighter carcass weights and tightened supplies due to the recent heat wave also helped prop up prices.

The terminal markets traded from steady to as much as $1.50 a hundred pounds higher with top prices ranging from $68 to $74 a hundred pounds.
