[Jan. 



The alcohol grains are the only ones nsually found in the 

 Massachusetts markets. They contain 80 or more per cent, of 

 protein and about 12 per cent, each of fiber and fat. The rye 

 grains reach ^15 to 16 per cent, of protein, and contain some 

 13 or more per cent, of fiber. Recent analyses show that sub- 

 stantially all of the crude protein in distillers' grains is present 

 as true albuminoids. 



(e) Digestibility of DistiJIci's' Grains (Per Cent.) 



The alcohol or corn grains show a somewhat lower digesti- 

 bility than does the gluten feed, but are much more digestible 

 than the rye grains. If the average percentage composition is 

 multiplied by the above digestion coefficients, we have the per- 

 centage or ]iounds digestible in 100: —
