U.S. live cattle futures also fell, as the market's recent rally ran out of steam.
CME live cattle for August delivery closed down 1.45 cents, or 1.3%, to $1.117 per pound.
The market had jumped more than 10% in June heading into Wednesday, but the gains were not accompanied by an increase in open interest, leading analysts to question how long the rally could be sustained.
Traders also say packer demand is likely to decline in the next week as July 4 sales are finished.
Market losses accompanied by a tumble in corn futures, which could help spur more cattle production down the road. CME feeder cattle climbed on corn's slump. The August contract closed up 0.175 cents to $1.38 per pound.
