ations in their relative market values. Three grades usually are

Market Classes and Grades for Feeder and Stockeb Swine 
Feeder and Stocker Swine are those hogs and pigs that arc intended 
for further development by growth and fattening. As a general 
rule thev lack sufficient thickness and firmness of finish or fat to 
qualify for the better grades of slaughter animals. When such animals 
are used for immediate slaughter, however, they automatically are 
classified as Slaughter Hogs and Pigs and are graded according to the 
standards for slaughter animals. Normally Feeder and Stocker Pigs 
constitute a relatively small proportion of the total number of swine 
marketed annually. 
There are five possible classes for Feeder and Stocker Hogs. They 
are: Barrows, Gilts, Sows, Boars, and Stags, and three possible 
classes for Feeder and Stocker Pigs. They are : Barrows. Gilts, and 
Boars. Barrows and Gilts are the only classes of Feeder and Stocker 
Swine that appear on the market in considerable numbers. Feeder 
and Stocker Barrows and Gilts arc generally grouped together when 
offered for sale on the market. 
The usual market weight groups for Feeder and Stocker Hogs and 
Pigs are relatively narrow. 
The grades for Feeder and Stocker Hogs and Pigs are: Choice, 
Good. Medium, and Common. (See Circular Xo. 561). Market (lasses 
and Grades of Swine.)
