FARMER'S CYCLOPEDIA OF LIVE STOCK 



breeds for three years was as follows: 

 Yorkshires, 2.14; Poland-Chinas, 2.23; 

 Duroc- Jerseys, 2.27; Berkshires, 2.33; 

 Tamworths, 2.42, and Chester Whites, 

 2.46 cents. 



Before weaning it cost less to produce 

 a pound of gain with the Yorkshires 

 than with any other breed. 



In the slaughter tests, Yorkshires gave 

 a larger percentage of dressed weight 

 than other breeds. In quality and suit- 

 ability for the export trade, the Tam- 

 worths stood first, followed by Berk- 

 shires, Chester Whites, Duroc-Jerseys, 

 Poland- Chinas and Yorkshires, in the 

 order named. 



Tests at Central Experimental 

 Farms — A large number of feeding ex- 

 periments have been reported by the 

 Central Experimental Earm in Canada, 



with different breeds of hogs. In this 

 work no one breed has been found con- 

 stantly superior to any other. There 

 was often a greater difference in the 

 gains made between different animals of 

 the same litter, than between animals 

 of different breeds. 



Eor fattening purposes, however, cross 

 bred swine and grades have given better 

 results than pure bred hogs. 



The Ontario Agricultural College 

 has also carried on extensive feeding ex- 

 periments with different breeds of hogs. 

 Six of the leading breeds have been 

 tested by the college for a number of 

 years, to determine the economy of gain 

 and value for bacon. The following 

 table shows the rank of the different 

 breeds for the years 1896 to 1900. In 

 each case the breeds are arranged in 

 order of economy of production.

RANK OF BREEDS IN ECONOMY OF PRODUCTION. 



1896 

 Berkshire, 

 Tamworth, 

 Poland-China, 

 Duroc-Jersey, 

 Chester White, 

 Yorkshire. 



1897 

 Berkshire, 

 Tamworth, 

 Poland-China, 

 Chester White, 

 Yorkshire, 

 Duroc-Jersey. 



1898 

 Yorkshire, 

 Berkshire, 

 Duroc-Jersey, 

 Tamworth, 

 Chester White, 

 Poland-China. 



1899 

 Berkshire, 

 Tamworth, 

 Yorkshire, 

 Chester White, 

 Duroc-Jersey, 

 Poland-China. 



1900 

 Berkshire, 

 Yorkshire, 

 Duroc-Jersey, 

 Chester White, 

 Tamworth, 

 Poland-China. 



In all five tests, Yorkshire took the 

 lead as to suitability for the export 

 bacon trade. Tamworth stood next, 

 Berkshire easily ranked third in the five 

 years' work, while for economy of pro- 

 duction they stood first in four out of 

 five tests. 



In these experiments the grain re- 

 quired to produce 100 pound of gain 

 averaged 379 pounds for the Berkshires, 

 390 for the Tamworth, 369 for the 

 Duroc-Jerseys, 395 for the Yorkshire, 

 400 for the Chester White, and 401 

 pounds for the Poland-Chinas.
