Brewers' grains are nmch more watcxy than the original 

 grain. They contain about 24: per cent, of dry matter^ 

 and, on account of their richness in digestible albuminoidsj 

 have a narrow nutritive ratio. They seem to be very 

 agreeable to cattle, and are an excellent fodder for fatten- 

 ing or for mill?:, while they are not adapted for anitnals 

 that have to perfoiin severe work. 



Distillers' Grains. — In the nianfacture of distilled 

 liquors, the first stages of the process are essentially the 

 same as in the preparation of malt liquors, but, after the 

 fermentation, the mash is subjected to distillation to separate 

 the alcohol. The residue remaining in the still constitutes 

 distillers' grains or "slump." This has nmcli the same 

 composition as brewers' grains, except that it is more 

 watery, containing only about 8 or 9 per cent, of dry mat- 

 tei'. Like brewei's' grains it has lost chiefly non-nitrogenous 

 matters. It consequently has a narrow nutritive ratio, and 

 is a valuable addition to fodder poor in protein. More- 

 over, it contains a considerable proportion of mineral mat- 

 ters, which may be of advantage under some circum- 

 stances. 



j;:^^.,_Distillers' grains are best adapted for cattle, and 

 yield excellent results in fattening or feeding for milk, 

 when rightly used. For sheep, hogs, and horses they are 

 not well suited. 



In using tins feeding stuff, its watery nature should not 

 be forgotten. Its relatively large proportion of protein 

 renders it a suitable addition to a fodder deficient in this 

 nutrient ; while, on the other hand, the health of the ani-
