The original Chester White had its origin in Chester County, Pa., 
hence the name. There are two other strains known as the Improved 
Chester White or Todd's Improved Chester White, and the Ohio 
Improved Chester White, commonly known as the OIC strain. 
The color is white. The face is straight; the snout is usually longer 
than that of the Poland-China. The ear is drooped. In general 
conformation the Chester White and Poland-China are very much 
alike. 
The Hampshire breed was formerly known by the name of Thin

body and including the forelegs. The face is straight and the ear 
inclines forward but does not droop. 
The bacon type (fig. 2) differs from the lard type in that the 
animals are more active, have longer legs and stronger bones, and do 
not carry as much fat as the latter. Their bodies are longer than 
those of the lard hogs. The hams and shoulders are light but the 
bodies are deep and wide. The most popular market weight ranges 
from 175 to 200 pounds. 
The most common breeds of this type are the Tamworth and the 
Yorkshire. 
The Tamworth is of English origin and takes its name from Tam- 
worth in Staffordshire. The color varies from a golden red to a 
chestnut shade. The face is practically straight, the snout is long 
and straight, and the ear is inclined slightly forward.
