Chicago Mercantile Exchange (CME) live cattle futures gained on Tuesday, helped by strong cash prices and technical support, Reuters reported, citing analysts.

"Cash market is still hanging in there at $179 to $180 area. More than that in the north. So August was too big of a discount," said Alan Brugler, president of Brugler marketing. "If cash isn't going to go down, we've gotta go up."

CME August live cattle futures added 1.45 cents to 179.500 cents per pound. Most-active October live cattle gained 2.300 cents to settle at 181.825 cents per pound, the biggest daily gain since July 14.

August feeder cattle futures lifted 2.875 cents to 248.425 cents per pound.

"Today was just the ideal combination of higher fat cattle and lower feed costs. You're going to bid that into the feeders," said Brugler.

CME lean hog futures eased after reaching fresh four-month highs, though demand and cash prices provided support.

"They're still in a steep uptrend," Brugler said. "Technically there's not much resistance."
