134 Feeds and Feeding. 



and broken germs from the starch and gluten. These materials 

 pressed and dried were formerly sold as chop feed, but are now 

 known as fancy corn brau. The starch and gluten are run into 

 concentrating tanks and then passed very slowly thru long shallow 

 troughs. The starch settles down like wet lime in these troughs, 

 while the hard, flinty portion or gluten floats off into receivers, is 

 concentrated, and finally pressed in heavy filter cloths, run thru 

 steam dryers, and appears as gluten meal." 



Gluten meal is one of the richest of concentrates in crude pro- 

 tein and fat, while fair in carbohydrates and low in mineral mat- 

 ter. It is a heavy feed and but little used in its original form. 

 (635, 846) Gluten feed, composed of gluten meal and corn bran 

 ground together, is now the largest common by-product of glucose 

 and starch factories. It is rich in crude protein, fair in fat, and 

 rather low in carbohydrates and mineral matters. It is a most 

 valuable concentrate, especially in the ration of the dairy cow. 

 (636) The experiment stations report samples of gluten feed 

 showing acidity and artificial coloring matter. (344) The feeder 

 should insist upon this product being free from both, for, while 

 they may not be positively harmful, they detract from the palata- 

 bility and general wholesomeness of this otherwise most valuable 

 and satisfactory feed. Germ oil meal contains somewhat less pro- 

 tein and carbohydrates than gluten feed, but carries much more 

 fat and a fair amount of mineral matter. (638, 871) 



159. Hominy feed. — In the manufacture of hominy and brewers' 

 grits, the hulls, together with some of the starchy matter of the 

 com grain, are left over as by-products. These combined compose 

 hominy feed, a palatable, valuable concentrate of excellent quality, 

 being fair in crude protein and mineral matter, and rich in carbo- 

 hydrates and fat. (637, 847) 



160. Corn a carbonaceous food. — Corn as a grain has a high per- 

 centage of starch with a rather low crude protein and ash content. 

 Rich in starch and oil, it is plainly the function of this grain, when 

 fed to farm animals, to produce heat, energy, and fat. No other 

 grain equals corn for fattening, but because it is not rich in crude 

 protein and ash, it is not eminently suited for producing bone and 

 muscle in young and growing animals. (115) These deficiencies of 

 corn are easily supplied in other feeds, so that on most American 

 farms it ranks first in usefulness among all the grains.
