with oats, is regarded highly as a feed for producing milk and 

 butter fat. 



130. Dried Brewers' Grain. Dried brewers' grain is a 

 by-product of barley, being the residue left from brewing. 

 In brewing, the fermentable carbohydrates are converted 

 into alcohol and the protein, fat, and crude fiber are largely 

 left in the residue, hence dried brewers' grain is rich in 

 these materials. The dry matter and carbohydrates of the 

 dried brewers' grain are lower in digestibility than the same 

 proximate constituents of barley, while, on the other hand, 

 the protein and fat of the dried brewers' grain are more 

 digestible than those of barley. 



131. Rye. Rye is not keenly relished by stock. It 

 is subject, also, to a fungus disease, ergot, that may be 

 injurious. 



132. Wheat. Wheat, on account of its cost of production 

 and its value as a human food, cannot be used extensively 

 for feeding stock. When fed to farm animals, it is best 

 mixed with other grains, with the corn for work stock and 

 with oats for growing stock. 



The by-products of the manufacture of wheat into flour 

 shorts, middlings and bran are very valuable stock feeds. 



Wheat bran is the outer covering of the wheat kernel, 

 and is that part which is first removed in the manufacture 

 of flour. Its volume is large in proportion to its weight, 

 therefore it is often used to give bulk to a feed ration. Bran 

 contains a high percentage of crude protein and mineral 

 matter. It is an excellent feed for breeding stock of all 

 kinds, for horses, and for dairy cows. It serves to keep the 

 animal's stomach in good order and to build up bone and 

 muscles in young stock. It is also well suited for use in 

 balancing the rations of dairy cows. 



Wheat middlings are composed of the part of the kernel 

 below the bran. It is even higher in protein content than 

 bran and is an excellent material to form a part of the ration 

 of hogs and dairy cows.
