Recent attempts to control the production of hogs in the United States bring up many questions as to the nature of the hog enterprise and variations in the hogs marketed in different regions.

This bulletin presents information on: (a) The differences in the weights of hogs marketed in different parts of the United States; (b) Certain trends which have developed in the location of the com, hog and packing enterprises; (c) Data regarding the shipment of slaughter hogs from central markets; and (d) the variation in pork requirements in different areas.

A considerable portion of this information is rather common knowledge among packers and others in the hog trade but is not so commonly understood by producers of hogs.
