When it comes to work, Murphy-Brown goes 'whole hog.' The livestock production business is the world's largest hog producer. Murphy-Brown maintains some 895,000 breeding sows (more than 90% of which are genetic lines that produce the leanest hogs possible) and brings to market more than 16 million hogs annually. It operates about 450 company-owned farms in a dozen states, as well as international operations. The company extends its hog production through partnerships with more than 2,000 independent farmers and contract growers in the US. Murphy-Brown is part of meat maker John Morrell, itself a subsidiary of pork-processing giant Smithfield Foods.
