Lean hog futures also finished mixed as traders weighed Friday's softer prices for pork against a USDA report showing brisk consumption.
CME August hogs rose 0.1 cent, or 0.1%, to $1.0092 a pound. CME October hogs futures fell 0.1 cent, or 0.1%, to 92.47 cents a pound.
The USDA's cold-storage report from Friday showed higher supplies compared with June of last year, but a consumption rate that is rising, which points to brisk exports and potentially more buying by China, traders say. China has vowed in recent weeks to control the spiraling price of pork there.
Cash hog prices were reported mixed.
Some plants that bought aggressively Friday were quoting steady prices or didn't purchase additional hogs Monday, according to livestock dealers. Others were paying 50 cents to as much as $1 per hundred pounds higher to secure additional hogs after high temperatures and humid conditions slowed feed consumption and weight gains in the animals last week.
The USDA's pork carcass composite value, a measure of wholesale prices, on Friday fell 80 cents to $98.93 a hundred pounds.
The terminal markets traded mostly $1 higher prices from $65 to $66 a hundred pounds on a live basis.
