 as it will sprout. The experiments made at Wis- 

 consin are reported in the Twenty-third Annual 

 Report of the Wisconsin Agricultural Experiment 

 Station, 1906. 



Uses in America. 



In the United States 

 and Canada, barley is 

 used almost exclusively 

 for malting purposes and 

 as a food for domestic 

 animals. Its use as a 

 human diet is limited, be- 

 ing confined to a few 

 preparations commonly 

 known as pearl barley. In 

 the Pacific states barley is 

 grown generally as hay 

 and grain for horses. As a hay it is cut and cured 

 when in the early milk stage. The grain is fed whole, 

 or milled by passing between rollers which merely 

 crush it. If ground like mill feeds, the abundance 

 of gluten therein makes a sticky mass when brought 

 in contact with moisture. Horses are fed barley 

 only to a limited extent in the oat-growing states. 

 In Canada and the United States, swine and poultry 

 are fed rather generally on barley, and all feeders 

 attest to its high value as a producer of pork and 

 bacon of the finest grade. The use of barley as a 



feed for dairy animals. Horses and other farm 

 animals are fed to a limited extent on brewers' 

 grains, and are said to relish them. The brewers' 

 grains, which may be secured either wet or dry,

are the barley grains after the soluble dextrin and 

 sugar have been extracted for the purpose of 

 making beer. These by-products accumulate at 

 breweries in great quantities, and often can be 

 purchased for less than the actual fertilizing value 

 contained therein. By judicious feeding and a 

 proper regard to the saving of the manure a farmer 

 may secure the feeding value practically free. 



The digestible nutrients, fertilizing constituents 

 and composition as given in Henry's "Feeds and 

 Feeding" are as follows :

By-produds. 



The principal by-products of barley when used 

 for brewing, are malt -sprouts and brewers' 

 grains, the latter of which are used extensively as
