Smithfield Foods, the largest hog producer and pork packer in the world, said it has cut hog production in the United States by 20 per cent.
It has closed a packing plant at Vernon, California, which prompted hog production cuts there.
It also cancelled contracts with 26 farms in Utah, closed 35 farms in Missouri and closed a packing plant in North Carolina.
It also cut production in Arizona and along the Atlantic Ocean coast.
Tyson Foods shut down one of its pork-packing plants this year.
The industry has been suffering hog production losses.
