DESCRIPTION OF FEEDING STUFFS 



about 4 per cent protein, less than 1 per cent fat, nearly 50 per cent 

 fiber, and 36 per cent nitrogen-free extract. Buckwheat feed means 

 the entire refuse obtained in the manufacture of buckwheat flour, 

 and contains ordinarily one-half to two-thirds of hulls, the balance 

 being made up of the heavy, floury portion of the buckwheat grain 

 immediately inside of the hulls, known as middlings or shorts. 

 Buckwheat feed composed of one-half middlings and one-half hulls 

 will contain about 15.7 per cent protein and 24 per cent fiber, and 

 one containing one-third middlings and two-third hulls about 12 

 per cent protein and 30 per cent fiber. 4 A study of the digestible 

 components furnished by this feed and by wheat bran would lead to 

 the conclusion that a good quality of buckwheat feed (containing 

 not much over one-half hulls, by weight) is worth about 20 per 

 cent less than wheat bran. Buckwheat middlings are a very valu- 

 able and- rich feed, containing about 28 per cent crude protein and 

 7 per cent fat, with only 4 to 6 per cent fiber. It is highly prized as 

 a feed for dairy cows, but cannot often be obtained as a separate 

 article of commerce; most millers sell their entire amount of refuse 

 as buckwheat feed. 



Corn Feeds. The corn kernel (Fig. 36) consists of five dif- 

 ferent parts: An outer and an inner layer of skin or hull, a layer 

 of gluten cells, the germ, and the main starchy part (endosperm), 

 some of which is hard and flinty, and some soft. The New Jersey 

 station 5 made analyses of the different parts of the corn kernel 

 and determined the approximate proportion of each, with results 

 as shown in the table. 



Composition of Dry Substance of Corn Kernel, in Per Cent 



The most striking part of the data shown in the table is the 

 high protein, fat, and ash contents of the corn germ. This con- 

 tains 65 per cent of the total fat in the kernel, 16 per cent of the 

 protein, and 62 per cent of the ash (71 per cent of the phosphoric-
