136 Feeds and Feeding. 



grain when dried is known as malt, and the dried germs are 

 termed malt sprouts. 



180. Brewers' grains. — In the mannfacture of beer the brewer 

 extracts from the malt the soluble dextrin and sugar. The liquor 

 containing this is called wort, which upon proper fermentation 

 and further treatment constitutes beer. The malt grains, freed 

 from the dextrin and sugar, while in wet form are known as wet 

 brewers' grains, a by-product of great volume at all breweries. 

 It is evident from this presentation that the brewer who uses only 

 the starch of the barley grain does not care for varieties of grain 

 rich in protein, but rather the contrary. According to Eichard- 

 son, Marcker found that a first-class malting barley should not 

 carry over 8.67 per cent, protein, which is about two-thirds that 

 found in American grains. The requirements of the stockman 

 who seeks feeds rich in protein are in the opposite direction, so 

 that the poorest barley for malting may be the best for feeding. 

 Light-colored, bright barley makes beer of better color than dark, 

 weather-stained grains; hence the lower price paid by the malster 

 for weather-stained barley. 



181. Malt for stock.— Lawes and Gilbert, ^ after experimenting 

 with malt, conclude: "A given weight of barley is more pro- 

 ductive both of the milk of cows and of the increase in live weight 

 of fattening animals than the amount of malt and malt dust 



(malt sprouts) that would be produced from it 



Irrespective of economy, malt is undoubtedly a very good food 

 for stock; and common exi^erience seems to show that a certain 

 amount of it is beneficial when given in admixture, and in change, 

 with other food to young or weakly animals, or in making up for 

 exhibition or sale; that is, when the object is to produce a par- 

 ticular result irrespective of the economy required in ordinary 

 feeding. ' ' 



Occasionally malt slightly injured by fire or other cause is offered 

 for sale at a low price, and, knowing its value, the opportunity 

 for purchase and feeding at a profit should not be lost by the 

 watchful stockman. ^
