PRINCIPAL CHARACTERISTICS 43 



The points of excellence in favor of the Duroc-Jersey 

 are its hardiness, growthiness and prolificacy. The breed 

 is comparatively new in its present state of development 

 and hence has considerable of the strength and vitality 

 that is so prominent in the wild boar. In developing size 

 at a given age the Duroc-Jersey is good, though not bet- 

 ter than individuals of other breeds. 



Poland-China Swine. The Poland-China is a typi- 

 cal American breed developed under ideal American con- 

 ditions. The former Poland-China was a very prolific 

 large spotted hog of good quality. At present there 

 are two distinct types in the breed. The principal aim 

 of many breeders for a considerable number of years has 

 been to develop quality, early maturity, and smoothness 

 of form. The show yard set the standard for this type 

 and the breeders have followed to the extent that the Po- 

 land-China in this particular strain became so much re- 

 duced in size, in length of body, and in prolificacy, that 

 the usefulness of the breed for pork production was some- 

 what impaired. From the spotted hog which originally 

 existed this strain was developed with solid black color 

 except six white points. 



Many of the breeders having recognized the fact that 

 this strain of Poland-China is not as large or as prolific 

 as it used to be, have developed the other extreme. They 

 have refused to follow the standard as given above and 

 are breeding hogs with size, growthiness, and prolificacy, 

 irrespective of many of the fancy points. These hogs de- 

 velop enormous size, but are somewhat lacking in quality. 

 Nevertheless they are prolific and good feeders. 



The fine quality strain of the Poland-China is what may 

 be called an extra fancy type, being smooth throughout, 

 with thick, broad, heavy sides, smooth shoulders, broad,
