FIFTH ANNUAL YEAR BOOK— PART VI. 389 



OfiBcial weights taken at the World's Fair, St. Louis, give a fairly clear 

 idea as to the possibilities in the matter of scale of the Yorkshire hog. A 

 boar six and a half months old weighed two hundred and sixty-five pounds; 

 boars and sows twelve and a half months old, five hundred and sixty pounds; 

 sows fifteen months, old, five hundred and eighty pounds, three-year-old 

 sows, eight hundred and seventy and nine hundred and ten pounds respec- 

 tively. 



1 find upon referring to feeding experiments conducted at some of the 

 stations that the Yorkshire's record is a creditable one. Three separate 

 feeding tests, for example, were conducted at the Iowa Station in which the 

 Poland China, Duroc Jersey, Berkshire, Chester White, Tamworth and 

 Yorkshire hogs were used. According to the summary of these three experi- 

 ments the Yorkshire hog cost $1.14 per hundred pounds gain, the Poland 

 China, $2.23 per hundred; Duroc Jersey, $2.27; Berkshire, $2.33; Tamworth, 

 $2.42; and the Chester White, $2.46 per hundred. In these experiments the 



First prize six months improved Yorkshire Boar World's Fair, St. Louis. 



Yorkshires made the largest average daily gain of all breeds. At the On- 

 tario Agricultural College it was found, in tests carried on for a period of 

 five years, that less meal was required to make a hundred pounds of gain 

 on the Yorkshire than in the case of the Poland China, Daroc Jersey or 

 Chester White. In experiments at the Minnesota Station in which the 

 Poland China, Tamworth and Yorkshire were fed out, it was found that the 

 profit during a certain feeding period was $2.07 on Large Yorkshire and 

 only eighty-six cents on the Poland China. In the second experiment con- 

 ducted with these same breeds the average profit on the Yorkshire was 

 $3.40, while on the Poland China it was $2.58. 



The Minnesota and Wisconsin stations found that a Poland-Yorkshire 

 cross or a Yorkshire-Berkshire cross produced a hog that would feed out a 

 given weight more economically than any of the pure bred fat breeds, this 

 no doubt being due to the increased constitutional vigor imparted by the 

 Yorkshire blood.
