152 FIRST PRINCIPLES OF AGRICULTURE. 



meal. Brewers' grains and all of the gluten products 

 contain much less ash than the original barley or corn, 

 the soluble salts being extracted in the process of manu- 

 facture. 



Hominy Meal. Hominy meal, a residue in the manu- 

 facture of hominy, consists chiefly of the germ and hull 

 of the corn, and corresponds in composition with the 

 germ meal, though much richer in ash. 



Cottonseed Meal. Cottonseed meal is derived in 

 the manufacture of cottonseed oil from the cottonseed. 

 This feed is of two kinds : one in which the hulls of the 

 seed have been removed, in which case it is called " de- 

 corticated;" the other called "undecorticated," in which 

 the hulls have not been removed. Both are rich in pro- 

 tein and fat ; though the former is far superior as a food, 

 both because of its higher content of nutrients, and its 

 greater palatability and digestibility. The concentration 

 and nitrogenous character of these feeds make them 

 very valuable, particularly when fed in connection with 

 coarse products, though because of their concentration 

 they should be used with great care. 



Linseed Meal. This product, sometimes called oil 

 meal, is a residue from the manufacture of oil from flax- 

 seed, and is of two kinds, called " old process " and " new 

 process ; " the former derived when the fat is extracted 

 by pressure, the other when solvents are used. There 

 is but little difference in their feeding value, the larger 

 amount of fat in the "old process" being balanced by 

 an increased amount of protein in the "new process." 

 Both are rich in protein, and show a high rate of di- 

 gestibility.
