SUPPLEMENTARY FEEDS WITH CORN

Bone Meal and Hard-wood Ashes. — Henry also reports 

 three trials in feeding bone meal with com, and hard-wood 

 ashes with com, against com alone, six pigs from the same 

 litter being used in each trial. Eegarding 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 bone 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 ashes 

 were fed.

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 Sta,tion, 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 

 com 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.
