By the end of 2012 Smithfield Foods transitioned 38 percent of pregnant sows on its company-owned hog farms in the U.S. from gestation stalls to group housing systems. The world’s largest pork processor and hog producer is on track to completely phase out individual gestation stalls in the U.S. by 2017.

In addition, Smithfield’s international hog production operations will complete their conversions from gestation stalls to group sow housing for its company-owned farms by 2022. Smithfield's hog production operations in Poland (AgriPlus) and Romania (Smithfield Ferme) completed their conversions to group sow housing on company-owned farms a number of years ago. The company's Granjas Carroll de Mexico (GCM) and Norson joint ventures in Mexico are phasing out gestation stalls on company-owned farms by 2022.

Smithfield announced, in 2007 its decision to convert to group housing for pregnant sows on all company-owned U.S. farms based on input from customers.
