U.S. livestock futures ended mixed Friday in choppy trade, with hot weather, which could hurt demand, weighing on prices.

U.S. lean hog futures end mostly higher on support from pork prices and expectations of more Chinese demand.

CME lean hogs for August ended up 0.775 cents at 98.950 cents per pound while December fell 0.325 cents to 87.875.

The jump in pork prices was offset somewhat by the summer heat wave in the Midwest and its potential impact on demand.

Ginzel added that a failure to confirm more China purchases could cause prices to retreat.

Cash hog prices were reported mostly steady to firm. Some pork processors were looking for additional hogs to arrive the first half of next week. Selling interest was slowed by forecasts of a heat wave across much of the Midwest this weekend and most of next week.

Some producers may wait until the middle of next week before offering additional hogs for sale to allow the animals more time to gain weight and for a break in the hot temperatures, said livestock dealers.

The USDA's pork carcass composite value, a measure of wholesale prices, on Thursday rose 85 cents to $98.66 a hundred pounds, the highest since June 27.

The terminal markets traded steady with top prices from $63 to $65 a hundred pounds on a live basis.
