"Prime medium butchers," weight, 220-280 pounds, very smooth and highly 

 finished. "Light butchers" are of the same general type but lighter weight, 

 180-220 pounds. Butcher hogs comprise about 25 per cent of the hogs coming 

 to the Chicago market, and are commonly used for the fresh meat trade. Prime 

 butcher hogs, whether heavy, medium, or light, represent the highest quality of 

 fat hog. (Courtesy Illinois Agricultural Experiment Station.) 



"Prime heavy hogs," weight 350-500 pounds, the extreme of the fat or lard 

 type. At one time these hogs were much more numerous on American markets 

 than they are today, the decrease being due to the decreasing demand for fat 

 pork. (Courtesy Illinois Agricultural Experiment Station.)
