Lean hog futures closed higher with the biggest gains made in the late 2011 and 2012 contracts, lifted by limit-up corn prices.
April through July overcame losses from month- and quarter-ending profit-taking earlier in the session, rallying to close higher as well on widespread gains in other commodities.
April lean hogs closed up 0.17 cent at 93.72 cents a pound, highest since Feb. 10. June, the most-active contract, was up 0.72 cent, or 0.7%, at $1.0387, the highest level in the life of the contract.
The gains show that traders of lean hogs in the end focused on the high feed costs driven by limit higher corn prices, a broker said.
"We're not going to add any to the hog herd at these higher [feed] costs," said Ken Jolliffe, analyst with BIS Commodities.
In the cash markets, pork processors were quoting mostly flat prices for a few additional loads to be delivered this week but some higher bids are seen for deliveries next week, said livestock dealers and market managers.
Wholesale pork prices Wednesday climbed $1.51 per hundred pounds to $94.78, a fresh seven-month high. The pork carcass composite value is approaching the all-time high of $96.74 hit on Aug. 24, 2010. Wednesday's carcass value was up 30% from a year ago and the year-to-date average increase is up 23%.
