CLASSES OF HOGS 
Hogs are divided into five classes ,such classes being based on sex 
condition. The classes of hogs are barrows, gilts, sows, stags, and 
boars. 
A barrow (figs. 11 to 13) is a male hog which was castrated before 
it had reached sufficient maturity to make reproduction possible and 
has developed physical characteristics peculiar to its class. As a 
rule castration is done when the animal is but a few weeks old. 
A gilt (figs. 14, 15, and 16) is a female hog which has neither had 
pigs nor reached a state of advanced pregnancy. 
A sow (fig. 17) is a female hog which has had pigs or has reached 
a state of advanced pregnancy. 
A stag (fig. 18) is a male hog which was castrated after it had 
reached sufficient maturity to make reproduction possible and which 
has developed many of the physical characteristics peculiar to the 
uncastrated adult male. 
A boar (fig. 19) is an uncastrated male hog which has reached 
sufficient maturity to make reproduction possible and has developed 
the physical characteristics peculiar to its class. Boars as a class 
show more pronounced development of the masculine character!stics 
than do stags. 
Practically all hogs reach market maturity and are slaughtered at 
a comparatively early age, consequently the various factors which in 
more aged animals bring about important changes in the tissues and 
body structure have not had as much time to function as is ust ually 
true in the case of cattle. Thus, while there are, actually, five classes 
of hogs based on sex condition, most hogs marketed as barrows and 
gilts are comparatively young and for that reason do not show the 
marked differences in conformation, finish, and quality attributable 
to sex condition so apparent in more aged animals. Hence they 
usually sell together without appreciable discrimination either in 
demand or prices. For that reason, in this schedule, these two classes 
have been combined. 
SUBCLASSES OF HOGS 
Each class is divided into subclasses on the basis of the general 
use to which the animal or its carcass is put. Slaughter is one sub-
