containing a greater proportion of protein, make the pro- 

 duction of the bacon type profitable. This type is also 

 much grown in Canada, where the Large Yorkshire is one 

 of the most important breeds. Relatively few of the bacon 

 type of hogs are grown in the United States. 



The following points will aid in distinguishing the 

 breeds: The Poland-China are black with white markings, 

 and have drooping ears. The Berkshire are about the same 

 color, but have erect ears. The Essex are black, with erect

 black with a belt of white around the body. The Large 

 Yorkshire, Small Yorkshire, Cheshire and Suffolk are all 

 white, with erect ears. The Chester- White are white, 

 with drooping ears. The Duroc-Jersey are cherry-red, 

 chestnut or yellowish red, with drooping ears. 



The white breeds are more prominent in the northeastern 

 states and Canada. They are said to be less desirable in 

 the intense sunshine of the corn-belt. Poland-China are 

 the most numerous breed in the corn-belt. The chief com- 

 plaint against them is that they are so fine-boned as to 

 lack in vigor, and that they do not raise large enough 

 litters of pigs. The Duroc-Jersey have been increasing 

 in numbers, and are said to be more prolific and more 

 vigorous than the Poland-China. Both of these breeds 

 and the Berkshire are popular.

 practice was to keep hogs in small pens that of necessity 

 became muddy. This practice is still common in many 

 sections of the country. But, where hogs are grown in 

 large numbers, the importance of pastures is now recognized.
