 Spotted Poland China. Others of less prominence are

America has produced very few new breeds of horses, 

 cattle or sheep, but a number of good breeds of swine have 

 been developed here. Swine from Europe are not so well 

 suited to the use of American field corn as to the grains of 

 their own country. Many of the English breeds are of the 

 bacon type and will not thrive so well on corn. The 

 Berkshire is the only very popular English breed in this 

 country. The Poland China originated in Ohio, the Chester 

 White in Chester County, Pennsylvania, and the Duroc- 

 Jersey in New Jersey. 



The Poland China (Fig. 185) and the Berkshire are both 

 black with some white markings on the face, legs, or other 

 parts. The Chester White and the strain called Ohio Im- 

 proved Chester (O. I. C.) are white in color. The Duroc- 

 Jersey is red or some modification of that color. These are 

 all large in size and the pigs mature early. The Berkshire has 

 erect ears and a dished face; in the others the ears are droop- 

 ing. The Duroc-Jersey is liked throughout the country 

 because of the large litters of pigs. 



The white breeds of swine are not much used in the South 

 and Southwest because of the greater danger of skin diseases 

 in hot, sunny climates. (See U. S. Farmers' Bulletin 765 

 Breeds of Swine.) 



Which Breed of the Bacon Type. The Large Yorkshire 

 (Fig. 187), Tamworth (Fig. 180), and Hampshire are the 

 leading breeds of the bacon type of swine. The last men- 

 tioned originated in Kentucky and the others in England. 

 The Large Yorkshire is white, the Tamworth red, and the 

 Hampshire black with a wide white belt. 



How to Begin Swine Raising. The beginner should start 

 on a small scale. Losses from too large numbers may be 

 serious and cause discouragement. There are several safe ways 

 of beginning.
