DESCRIPTION OF FEED STUFFS 



finely ground si f tings and waste from com meal prepared 

 for home consumption, as well as that secured in making 

 cracked corn. This waste meal has a feed value about 

 equal to ground whole corn. Corn chop usually refers 

 to ground whole corn, although other ground corn by- 

 products may be included in it. It is usually a much 

 coarser product than com meal. Ground grains have no 

 more feed value than these same grains in their whole or 

 cracked forms, but the best results in feeding poultry are 

 secured where about one half of the feed is given in the 

 whole or cracked form called scratch feed and the rest 

 in the form of finely ground grains and meat feeds which 

 make up what is called the mash. 



Corn and cob meal, which is the corn and cob ground 

 up together is not adapted to poultry feeding on account 

 of its high fiber content and fowls are not able to digest 

 or utilize crude fiber as well as live stock. Commercial 

 starch and glucose are manufactured from corn by soak- 

 ing the com in water containing some acid and separating 

 the desired constituents. Four products are secured in 

 this process ; the germ, used in making com oil and germ 

 oil meal or corn oil cake; the bran made up of the hulls; 

 the gluten, and the starch. Corn gluten feed contains the 

 gluten and the corn bran to which is added the residue 

 from the water used in soaking the corn, making a rich 

 concentrated food. It is rich in crude protein and fat 

 and contains considerable carbohydrates. The composi- 

 tion of this feed is quite variable, depending on its manu- 

 facture, but the protein usually ranges from i8 to 29
