THE FAT OR LARD BREEDS OF SWINE 425 
crossing on other breeds, as well as on common, or grade 
stock. A cross between the Large Yorkshire and the 
Poland-China has been found to give an excellent hog, 
both from a farmer’s and a packer’s standpoint. For 
crossing with the Berkshire, Duroc-Jersey and Chester- 
White, the breed is very highly esteemed, and the cross- 
breds are generally regarded as superior to the pure- 
breds for feeding purposes. 
The most serious criticism directed against the Poland- 
China is on the score of fecundity. In any breed in which 
so much attention has been paid to the development of 
fine bone and a very marked tendency to fatten, it is only 
natural to expect that there would be some loss of fecun- 
dity, and statistics appear to indicate that the Poland- 
China is no exception to the rule. This criticism applies 
especially to the very fine-boned types. 
514. Distribution. — The Poland-China is widely dis- 
tributed over the United States. The principal states in 
which the breed is found, according to the Secretary of 
the American Poland-China Record Association, are Iowa, 
Illinois, Texas, Missouri, Kansas, Nebraska, Indiana, 
Ohio, Minnesota, South Dakota, Wisconsin, Oklahoma 
and Michigan, but there are few states where Poland- 
Chinas are not to be found. 
In Canada, the breed has not obtained a very strong 
foothold. Outside of the United States and Canada the 
breed is but little known. 
515. Organizations and records. — Organizations in 
the interests of Poland-Chinas are numerous. The largest 
organization is the American Poland-China Record Asso- 
ciation, which was organized in 1878 and published its 
first herd-book in 1879, and has published sixty-four 
volumes to date, containing the names of 390,000 animals.
