BARLEY 
The preceding figures show the amount of each 
material contained in a hundred pounds of the grain. 
Some of this is digestible and useful to the animal. 
Much of it is indigestible and worthless. 
The next table gives the per cent, of each of these 
that is commonly considered as digestible.

No figures are given in the above for bald barley. 
So far as the present writer is aware, no digestion ex- 
periments have been made with this grain. From its 
nature, it is fair to presume that it would be about as 
digestible as wheat, and the figures for wheat have been 
used in making, the calculations of the following table.

*Used in the feeding experiments. fAverage composition. 
This last table is obtained by combining the other 
two. Thus the first table gives a hundred pounds of 
common barley as containing 8.66 pounds of crude 
protein; the second table says that 75 per cent, of this is 
digestible. Hence 100 pounds of common barley contain 
6.60 pounds of digestible iDrotein.
