John 250, when I worked for Smithfields, we had a lecture from the procurement manager supplying the mill at Rosehill NC, he explained their buying policies, including buying local feed quality corn and wheat ahead from corn belt farmers, even a few cents per ton makes a saving with the volume purchases. Imports are not always conventional grain sources, but they will buy surplus rice or even tapioca if the volume and price are right. There were many price cutting measures mentioned including re-cycling hog mortalities, using the rendered fat for an added energy source for the hogs, and the carcase meal used for the \butterball turkey rations.
