DESCRIPTION OF FEEDING STUFFS 



ing of the buckwheat kernels, which are readily separated there- 

 from. They have practically no feeding value whatever,, although, 

 if finely ground, they may serve a purpose as dilutant of heavy 

 feeds, like corn meal or buckwheat middlings. The hulls contain 

 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-thirds 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 wheait bran. Buckwheat middlings are a very valu- 

 able and rich feed, containing about 28 per cent true 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.
