Corn Substitutes for Growing Pigs 307 



In both experiments the pigs receiving the starch corn 

 germ meal alone did little more than maintain themselves. 

 On the other hand, the gains by the pigs receiving the 

 hominy corn germ rneal were on the average 1 .36 pounds 

 daily. Feeding both starch corn germ meal and corn in 

 separate compartments of the self-feeder resulted in the 

 pigs eating very little of the former. When it was fed 

 with tankage, free-choice, the pigs ate nearly as much 

 tankage as they did starch corn germ meal. 



The unsatisfactory results obtained in these trials 

 from feeding corn germ meal as maunfactured by the 

 starch factories were obviously due to its unpalatability. 

 The use of acid in loosening the germ layer in its manu- 

 facture was believed to be the reason why it was not eaten 

 with relish. Hominy corn germ meal proved to be nearly 

 as palatable as corn. 



Corn gluten meal and corn gluten feed. 



The part of the corn kernel which remains after the 

 removal of most of the starch, germ, and bran in the manu- 

 facture of corn-starch and glucose is officially named 

 corn gluten meal. It contains most of the corn gluten. 

 It may or may not contain the so-called corn solubles 

 which represent the part of the protein and mineral 

 phosphates which go into solution in the processes of 

 separation. Corn gluten feed is the same as corn gluten 

 meal with the bran added. Gluten feed is consequently 

 more bulky and less digestible than gluten meal. 



Gluten feed contains from 17 to 25 per cent of protein, 

 and gluten meal from 27 to 36 per cent. Although 

 sufficiently rich in protein to suggest large usefulness 

 for balancing a corn ration, they have never proved popu- 

 lar in practice, and are generally regarded as being more
