MARKET CLASSES AND GRADES OF LIVESTOCK 
Considering the industry as a whole, swine husbandry has prob- 
ably reached a higher stage of development in the United States 
than is true of either cattle or sheep. Although the best bred cattle 
and sheep make just as near an approach to perfection as do the 
best specimens of hogs, considering market receipts as a whole, 
swine show a higher average of breeding than do any other kind 
of meat animal. 
For simplification swine are first divided into two general groups— 
hogs and pigs. This grouping is also in keeping with market prac- 
tice. 
A hog is a member of the swine family which has reached sufficient 
maturity to make reproduction possible. The animal may be inea- 
pable of reproduction because of having been castrated or unsexed, 
or because of certain physical abnormalities.
