gone, the germs are gone, therefore, gluten meal must he 



very high in protein. 



Gluten feed is gluten meal mixed with the corn bran and 

 the material which is dried out from the "steep" water that 

 the corn was originally steeped in before grinding. The 

 ofificial definition of gluten feed is "Corn gluten feed is that 

 portion of commercial shelled corn that remains after the 

 separation of the larger part of the starch and the germs by 

 the processes employed in the manufacture of cornstarch 

 and glucose. It may or may not contain corn solubles." 

 In order to bring out the differences, the following analyses 

 are given.

This table clearly shows how the addition of the corn 

 bran to the gluten meal gives gluten feed. Comparison 

 with the first table in the paper shows the differences 

 between the corn milling processes and the glucose starch 

 processes, and therefore, the difference between hominy 

 feed and gluten feed. Gluten feed has more protein and 

 less carbohydrates and less fat because in the practically dry 

 milling of the corn mill more starch is left in the by-product 

 but a great deal of the protein goes into the main products. 

 More fat is found in the hominy feed because in the first 

 place all of the germs are not separated out and in the second 

 place the germ oil meal goes back into the hominy feed. In 

 the wet processes which give rise to gluten feed a very large 

 proportion of both the hard and soft starch goes into the 

 main product but all of the gluten or protein is left behind in 

 the by-product. None of the germ is left in the by-product 

 consequently gluten feed is high in protein but only medium 

 in carbohydrates and low in fat. However, so closely do 

 these differences offset each other that the amount of total 

 digestible nutrients in one ton of hominy, 1692 pounds, is 

 only slightly larger than the amount of total digestible 

 nutrients in one ton of gluten feed, 1614 pounds. The amount 

 given for the hominy is probably too high because most of 

 the analyses for hominy given in "Feeds and Feeding," from 

 which these analyses are quoted, are for hominy containing
