44 BREEDS OF SWINE 
Bacon and Fat Types Compared.— Another interesting 
point brought out in these breed tests is the fact that the bacon 
type is able to hold its own against the lard type in economy 
of production. Take the two bacon breeds, Yorkshire and 
Tamworth, in the Ontario tests and compare their standing 
with such breeds as the Poland-China, Chester White, and 
Duroc-Jersey; or take the Yorkshire in the Iowa tests and 
compare it with the other breeds, So far as breed tests go, 
therefore, they fail to demonstrate that it costs any more to 
put a pound of gain on a hog of bacon type than it does to 
put a pound of gain on a hog of lard type. 
Conclusion.—Breed tests, therefore, have served a useful 
purpose in demonstrating that no one breed is superior to all 
other breeds in ability to make cheap gains. A healthy, thrifty 
hog will make economical gains no matter what breed it 
represents.

poorest?

individuals of the same breed?
