CORN OIR CAKE MEAL FOR GROWING AND FATTEN- 
ING PIGS. 
JOHN M. EVVARD AND RUSSELF DUNN* 
Corn oil cake meal is really a residue of the germs of corn 
grain which remains after most of the oil is extracted therefrom. 
The particular corn oil cake meal which we used in our test is a 
by-product from the manufacture of glucose. These four main 
products are made from the corn grain : Glucose, corn oil, gluten 
feed, and corn oil cake meal. It is with the latter that we are to 
deal. 
The corn oil cake meal according to approximate analyses con- 
tains approximately in every 100 pounds 9 pounds of water, 22 
pounds of crude protein, 47 pounds of nitrogen-free extract, 10 
pounds crude fibre, 10 pounds of ether extract, and 2 pounds of 
ash. 
In removing the oil from the separated corn germs or embryos 
the separation is largely physical although the germs are heated to 
the scorching point in the process. 
To more clearly comprehend the action of this corn oil cake 
meal of which there is less than 2 pounds manufactured from a 
bushel of corn it is well to emphasize some of the main essentials 
of the adequate ration for young growing and fattening pigs : 
First — The protein quantity must he large enough in order to 
meet all demands for growth and general metabolism. 
Second — The protein quality must he right, which means that 
there must be a correct proportion existing among the various 
amino acids of which there are some twenty, as well as a suffi- 
ciency of the .essential ones within the mixture. 
Third — A sufficiency of minerals is of considerable importance, 
otherwise the bodily mechanism which is in a growing state will 
be severely handicapped. 
Fourth — Mineral quality should likewise he carefully attend- 
ed to so that the apportionment of the various elements within the 
total mineral quantity shall be adequate in every particular — 
which means that there shall be, specifically speaking, just enough
