Distillers' dried grains consist chiefly of the dried 

 Distillers' hulls, germ, and other non-fermentable portions 



Dried Grains of the grains left after the manufacture of distilled 

 Page 10. liquors from the cereal grains. In a wet state this 

 residue is known as distillers' slop. The quality 

 of the dried grains depends first, upon the quality of the distillers' 

 mashes (upon the kinds and proportions of the grains employed), 

 second, upon the distillers' mode of mashing, and third, upon the 

 process of drying. Distillers' grains derived from corn have the 

 highest feeding value while those derived from rye have the lowest. 

 If heated too hot in the process of drying, it is scorched, which 

 causes a disagreeable taste and odor and a lessened digestibility. 

 On account of the removal of much of the digestible carbo- 

 hydrate matter through fermentation, distillers' grains form a very 

 acceptable component of a ration rich in carbohydrates or starch. 

 The two rations following will be found well suited to milk pro- 

 duction with corn distillers' grains as a component. 



I. 



150 lbs. distillers' grains, 



150 " standard middlings, 



100 " corn or hominy meal. 



Mix and feed 7 pounds or quarts daily. 



II. 



150 lbs. distillers' grains, 

 50 " corn or hominy meal, 

 50 " cottonseed meal. 

 Mix and feed 7 pounds or quarts daily. 

 Individual samples of the several brands of distillers' grains 

 varied considerably in analyses. This variation may have resulted 

 in a large measure, from the difficulty of sampling accurately, due
