BARLEY 
15 
FEEDING VALUE OF BARLEY. 
The value of any material as a food can be tested in 
two ways: first, by submitting it to chemical analysis to 
ascertain the amount of food constituents it contains* 
second, by feeding it to stock and noting the results. 
Our study of barley includes both of these methods. 
The method by chemical analysis is the easier and 
quicker, but it is not certain yet that we know how to 
interpret the figures obtained by the analysis. The work 
has been confined to two representative varieties: the Cal- 
ifornia as the best of the non-malting common barleys, 
and the Smooth Hulless as representing the bald barleys. 
For the remainder of this bulletin the terms “common 
barley” and “bald barley” will be understood as referring 
to these varieties. Both kinds were analyzed and the 
analyses are given herewith, in comparison with those of 
corn, wheat, oats, and bran, since these are the feeds 
with which barley comes most in competition. The 
analyses are of the material in the air dry condition in 
which it is usually fed.
