INTRODUCTION. 
Heretofore feeds and labor have been so abundant and have been 
available at such moderate prices that close calculation in tieir use 
has been unnecessary. The present war has caused the American 
farmer to make a closer study of the economics of the national feed 
situation than ever before. Ifa large part of the corn, wheat, barley, 
and similar carbonaceous grains must be saved for human consump- 
tion, then farmers who raise and fatten live stock will have to prac- 
tice stricter economy in their feeding operations. 
The hog is a heavy and promiscuous feeder. He is not a ranger 
and does not thrive on pasture alone. The grain fed to swine, how- 
ever, can be reduced greatly by. making wider use of nitrogenous 
feeds. Since the feeding stuffs of high protein content are already 
in great demand, now is the time to call upon the reserve supply of 
protein furnished by waste fish and by the waste from fish-canning 
industries. Many years ago attention was called to the possibilities of 
fish meal as a feeding stuff, both in this country and abroad, and it is 
indeed surprising that its use as a feed for stock has not been fostered 
in this country. 
17The fish meal used in these experiments was made under the direction of Dr. F. C. 
Weber, Chemist in Charge, Animal Physiological Chemical Laboratory, Bureau of Chem- 
istry. Acknowledgment is here made for his interest and cooperation, which made the 
experiments with fish meal possible.
