SUPPLEMENTARY FEEDS WITH CORN 151 
Bone Meal and Hard-wood Ashes.—Tlenry also reports 
three trials in feeding bone meal with corn, and hard-wood 
ashes with corn, against corn alone, six pigs from the same 
litter being used in each trial. Regarding these trials the 
author writes: 
“As the trials progressed, it. became evident that none of 
the pigs were properly nurtured, though the difference in 
favor of those getting hone meal or ashes was very marked. 
The pigs allowed neither ashes nor bone meal were most plainly 
dwarfed. . . . These dwarfs became so fat that the Jowls and 
bellies of some of them nearly touched the ground.” 
The following table, taken from “ Feeds and Feeding,” 
shows some striking differences: 
When bone When ashes | When neither 
meal was fed. were fed. was fed 
Corn meal required to produce 100 
pounds of gain, pounds.......... 487 491 629 
Average breaking strength of thigh- 
bones, pounds.................. 680 581 301 
Average ash in thigh-bones, grams. . 166 150 107 
It will be seen from the above table that the appetite of 
the hog for such substances as ashes is not without significance. 
Wheat Middlings and Skim-Milk.—J. G. Fuller, of the 
Wisconsin Experiment Station, reports an experiment with 
two lots of Berkshire pigs. They were young pigs, weighing 
about 51 pounds each when the experiment began. One lot 
was fed corn meal only, and the other was fed a mixture of 
corn meal, wheat middlings, and skim-milk. The following 
conclusions are drawn from the experiment: 
If the pigs were valued at the same price per pound, the 
mixed ration lot would return a profit practically four times 
that of the corn lot.
