BREED TESTS. 
IM- i.i BN( i: I 'i BREED ON FEEDING Pi >\\ BBS. 
In the foregoing pages attention has been called i<> the fact that 
there is very little difference in the standards of excellence for the 
various breeds of what has come to be designated the "lard," "fat," 
"block," or "corn-belt" hog. Tests of the different breeds made in 
different parts of the count ry show t hat , with standards t hat are simi- 
lar to a large extent, their is very Little difference in the cost of pork 
product ion by the best represents ives of any of the established breeds. 
Indeed, these experiments show rather more, for they indicate that 
the breeds of the bacon type rank well in economy of gain with those 
of the "corn-belt n lard type. Curtiss and Craig quote Hayward of 
the Pennsylvania Station to the effect that the results obtained in 
.Maine, Massachusetts, and Ontario show the feed eaten per LOO pounds 
gain by various breeds to l>e as follows: Poland China. i"7 pounds; 
Berkshire, 419 pounds; Tamworth, 420 pounds; Chester WTiite, 
pounds; Duroc .Jersey, 522 pounds. 'The writer has averaged results 
Tor six Leading breeds obtained by various experiment stations when 
there were a sufficient number of tests and a total number of pigs 
Large enough to make the averages thoroughly representative. Te- 
stations whose figures weir used are Maine, Vermont, New York 
State, Michigan, Wisconsin, and Iowa, in the United States, and the 
Ontario Agricultural College and the Central Experimental Farm, in 
Canada. The following table Shows a variation in teed per 1"" pounds
