MARKET CLASSES AND GRADES OF LIVESTOCK

GRADES 
A market grade for Swine, as for other kinds of livestock, is a 
specific indication of its degrees of excellence in relation to the entire 
range of excellence possible for such animals. Various classes, groups, 
and grades are shown in the schedules for Hogs and Pigs, and are 
fully explained in Circular No. 569, Market Classes and Grades of 
Swine. 
MARKET CLASSES AND GRADES EOR SLAUGHTER HOGS 
The market classes for Slaughter Hogs are: Barrows, Gilts. Sow-. 
Boars, and Stags. 
The grades for Slaughter Hogs are: Choice (Fat type), Choice 
(Meat type). Good, Medium, and Cull (fig. 8). These grades apply 
more specifically to Barrows. Gilts, and Sows. As a rule, Boars and 
Stags are not graded. The grades for Slaughter Hogs are fully 
explained in Circular No. 569 Market Classes and Grades of Swine. 
Significance of "Type" in the Slaughter Hog Classification.— 
The term ••type" is used only with the Choice grade and in combina- 
tion with the words "Fat" or "Meat" as "Choice (Fat type)" or 
-Choice (Meat type)," (fig. 9). These terms "Choice (Fat type)" 
(fig. 10) and "Choice (Meat type)" are used to designate and differ- 
entiate between two grades of finished Slaughter Hogs, both of which 
are Choice or No. 1, but the carcasses and cuts from each type are 
different in many respects. The carcasses have different proportions 
of fat to lean and produce different quantities or percentages of 
primal wholesale cuts of pork. The Choice (Meat-type) hog is rela- 
tively long and narrow and has a lower proportion of fat to lean 
than the Fat-type hog. The Choice (Fat-type) hog is wider in pro- 
portion to its length and depth and has heavier or thicker deposits 
of fat than the Choice (Meat-type) grade hog of the same weight.
