EXPERIMENTS IN PIG FEEDING 



In looking over the results we see there is but a slight 

 margin in favor of the lot fed ground corn and cob. During 

 the entire four weeks, with same food, differing only in the 

 conditions fed, there was a difference of but 3 pounds for 

 the whole period, and the difference in the average daily gain 

 was but .06 pounds in favor of Lot B. 



The next table shows the comparative value of the two 

 methods.

It will be observed that the same amount of milk and corn 

 was fed in both cases, with the result that the ear corn lot 

 required 89<} pounds of milk and 333 pounds of grain, as 

 against 855 pounds of milk and 319 pounds of grain of the 

 ground corn and cob to produce 100 pounds of gain — live 

 weight. This is a difference of 14 pounds of corn, including 

 the cob. At the rate of $16 per ton, the 14 pounds has a 

 value of 11.3 cents. 



Counting the cost of grinding a bushel of corn at eight 

 cents, 100 pounds would cost 12 cents for grinding. The 

 14 pounds gained by grinding has therefore a less feeding 

 value than the amount paid for grinding, and we have saved, 

 at the same time, the expense and labor of hauling to and 

 from the mill. 



CONCLUSIONS FROM THIS EXPEEIMENT. 



1. Ground corn and cob has a slightly better feeding 

 value than corn on the ear. 



2. For practical purposes it is more economical to feed 

 corn on the ear rather than hauling to the mill and grinding 

 for feed.
