sist of the light, fine, thin, membranous coating set free from the 

 crease of the wheat kernel in the process of crushing the wheat. 



From Rye. These products are secured from the same portions 

 of the rye grain as are the bran and middlings from the wheat 

 kernel. 



From Buckwheat. Bran consists of a mixture of buckwheat 

 hulls and middlings prepared by the millers of buckwheat to enable 

 them to dispose of buckwheat hulls. Middlings consist of that por- 

 tion of the buckwheat grain immediately inside the hull and are 

 rich in crude fat and crude protein and have a high feeding value. 

 Mixed Feed consists of relatively large proportions of middlings and 

 shorts and a small proportion of hulls. Two of the samples were 

 deficient in crude protein. 



From Corn. Bran consists of the outer coating of the corn 

 kernel and is variable in composition, depending on the process of 

 manufacture. It is of low feeding value and is often used as an 

 adulterant for wheat bran and other wheat by-products. Hominy 

 Feed or Chop consists of the bran coating, germ and part of the 

 starch portions of the corn kernel secured as a by-product in the 

 manufacture of hominy. Hominy Hearts are secured as a by- 

 product in the manufacture of hominy and consist of the germ or 

 heart of the grain. 



Gluten Meal This is a by-product of corn, produced in the 

 glucose factories in the manufacture of starch. It is difficult to se- 

 cure detailed information as to the various steps employed in the 

 manufacture of these products, due to the fact that the owners of 

 these factories prefer to withhold some things from the public. The 

 following points in regard to the preparation of the same may be of 

 interest to feeders. The corn is first soaked, then by mechanical de- 

 vices the different parts of the corn are separated. First the germ 

 is taken out; then the bran, which is the hull of the corn, is sepa- 

 rated from the gluten and starchy portions. The gluten and starch 

 are then separated by a filter process. The starch, being the heavier 

 of the two, settles to the bottom, while the gluten runs off and is 

 taken to the feed house where it is kiln dried into gluten meal. 



Buffalo Gluten Feed. This, like gluten meal, is a by-product 

 of corn, produced in the manufacture of starch. It differs from 

 gluten meal in that it contains the hulls (corn bran) as well as the 

 gluten part of the corn. Gluten and corn bran are found in gluten 

 feed in about the following proportions: gluten 55 per cent; corn 

 bran or hulls 45 per cent. The corn bran gives it more bulk than 

 gluten meal, thus making it an easier product to feed. It does not 

 contain as much protein, however, as gluten meal. For the average 

 farmer we would recommend the use of gluten feed in preference to 



fluten meal unless his other grain feed is of a bulky nature. (la.

Hominy Feed. Hominy, as manufactured for human use, 

 consists of the hard or flinty part of the corn kernel. The hull, 

 germ, and part of the starch portions of the kernel constitute the
