and the combination sold as mixed feeds. These barley 

 feeds therefore vary greatly in feeding value. 



Hominy Feeds. — Hominy is made from corn. Only the 

 best grains are used and these must grade up to a certain size. 

 From the select grains the outside hulls and tips are removed. 

 The coarse tips and seed coats and a great many small ker- 

 nels are left as by-products. These materials are mixed 

 together in various ways and sold under a great variety of 

 trade names such as hominy chop, and hominy feed. Their 

 feeding value is shown by chemical analysis. 



BY-PRODUCT FEEDS FROM THE MANUFACTURE 

 OF STARCH AND GLUCOSE 



Corn is used in the manufacture of starch and glucose. 

 Since only the starch grains are desired by the manufac- 

 turer, the by-product materials are made up of the hull, the 

 tips, the germs, and the gluten portions of the corn kernel. 

 The feeding stuffs thus obtained appear below. 



Corn Bran. — This material is made up of the outside 

 layer of the corn grain and is removed in the earliest part of 

 the starch-making process. It contains a high percentage of 

 crude liber and mineral matter. It does not equal wheat 

 bran in feeding value, and is generally used to adulterate 

 other by-products to form some of the so-called mixed feeds, 

 sold under the names of sugar feeds and starch feeds. It is 

 also used to mix with the gluten meal to form gluten feed. 



Germ Meal. — In another part of the starch-making 

 process the germs of the corn are removed. These germs 

 are ground and the oil is pressed out, leaving germ oil cake. 

 This ground cake forms germ oil meal, a feeding stuff high 

 in protein, mineral matter, and fat. It is valuable to mix 

 with some of the coarser concentrates, but when left in stor-
