SUPPLEMENTARY FEEDS WITH CORN 163 
been in progress 81 days. It is stated that there is a risk in 
feeding cottonseed meal. It is claimed, however, that cottonseed 
meal can be fed with safety, even in large amounts, for periods 
of not more than 25 days. When no deaths occurred, cotton- 
seed meal proved equal to tankage as a supplementary feed 
with corn.* 
Summary.—Many other instances of the effect of supplementary feeds 
with corn might be given if space permitted. Sufficient tests have been 
quoted to establish 4 few important points which may be enumerated as 
follows: 
1. Corn alone falls far short of being an ideal ration for hogs. It is 
especially injurious to young pigs, resulting in lack of growth, weakness 
of bone, and expensive gains. 
2. When wisely combined with a feed relatively rich in protein, corn 
makes one of the best hog feeds obtainable. 
3, Pasture, either grass or clover, makes a good supplement to corn, 
clover and alfalfa being especially desirable. ; 
4. Very high-priced protein feeds, such as tankage and meat meal, 
must be used in small proportions, and give best relative returns when used 
in dry-lot feeding. 
5. When hogs are on pasture, a comparatively cheap feed, such as 
wheat middlings, will supplement corn to better advantage than expensive 
feeds like tankage and meat meal. 
6. Where soy-beans can be grown to advantage, they constitute a 
valuable feed to use as a supplement to corn. 
REVIEW. 
1. What is the need of supplementary feed to be used with corn? 
” 2, What is found to be the effect of blood meal and pea meal? Why? 
3. What is the special need of such feed as bone meal and hard-wood 
ashes as a supplement to corn? 
4, Give the effect of using each feed discussed in this chapter along 
with corn. 
* There is evidently considerable risk in feeding cottonseed meal to 
hogs, though the exact danger point has not been determined. It is not 
profitable to run much risk in the use of this feed, since the difference in 
cost between cottonseed meal and other feeds that are considered safer 
is now very small. 
The North Carolina Station has shown that giving iron sulfate in the 
drinking water, 1 pound to 50 gallons of water, or slop, will overcome the 
poisonous effects of cottonseed meal for pigs. See “ Productive Feeding of 
Farm Animals,’ by Woll.
