CHAPTER XX. 

 SUPPLEMENTARY FEEDS WITH CORN. 



IT HAS been already noted that corn is essentially a fat- 

 forming feed, and that it is not a good bone and muscle 

 former. The evil effects of exclusive corn feeding are most 

 conspicuous in the case of young, growing pigs, and numerous 

 experiments have been conducted in combining other feeds 

 with corn, which would tend to overcome its objectionable 

 features. The influence of exclusive corn feeding upon the 

 composition of the body has been discussed, but its influence 

 upon the growth and economical gains of the animal has yet to 

 be considered. 



Blood Meal and Pea Meal. In " Feeds and Feeding," 

 Henry, of the Wisconsin Experiment Station, reports gains 

 and feed consumed by three lots of pigs fed as follows: 



Lot 1 : % blood meal, % corn meal. 



Lot 2 : % pea meal, */ corn meal. 



Lot 3 : Corn meal only. 



During the trial, 



Lot 1 gained 202 pounds, and required 409 pounds of 

 feed for 100 pounds of gain. 



Lot 2 gained 180 pounds and required 449 pounds of feed 

 for 100 pounds of gain. 



Lot 3 gained 155 pounds and required 481 pounds of 

 feed for 100 pounds of gain. 



Blood meal is very rich in protein, and peas are much 

 richer in protein than corn. The effect of using such feeds 

 with corn is very noticeable in the larger gains and smaller 

 feed requirements for 100 pounds gain.
