hair. It was valued because of its size, strong constitution, and 
rapid growth. 
At the same time the Jersey-Red was being developed, a similar 
breed was being formed in Saratoga County, New York. This 
breed subsequently became known as the Duroc. This strain owes 
its origin to Isaac Fink, who procured a red boar and used it on his 
common sows with great success, so that his herd became very 
popular. The Durocs were finer in bone and carcass than the 
Jersey-Reds. 
The present Duroc-Jersey breed is the result of the amalgamation

the efforts of Colonel F. D. Curtis of Saratoga County, New

422. Duroc-Jersey compared with Poland China. — In many 
respects these two breeds are similar, although there is striking 
contrast in color, the Duroc-Jersey being always red, and the Poland 
China black. The head of the Duroc-Jersey is of medium length, 
and the face straight or slightly dished, the ears are of medium 
size and droop forward, and the body is broad and deep, with the 
back less arched than in the Poland China. Under similar con- 
ditions, the general quality and the quality of the meat compares 
favorably. When corn fed, both are too fat for foreign trade 
(Fig. 108).
