CHAPTER XX. 
SUPPLEMENTARY FEEDS WITH CORN. 
Ir was 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, 24 corn meal. 
Lot 2: 44 pea meal, 14 corn meal. 
Lot 8: 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.
