[Jan. 



Digestion Coefficients of Distillers'' Dried Grains (Per Cent.). 



[All experiments.] 



As a result of 16 sino^le digestion trials with 6 different 

 samples, several points may be noted : — 



(a) The dry matter coefficients differed considerabh^, but 

 the grains showed a high average digestibility. 



(6) The ash was apparently little digested. Whether 

 this was literally true, or whether a portion of it was sub- 

 stituted for the digestible ash of the hay, is not clear. 



(c) The protein in the several brands was quite evenly 

 digested, except in the first two samples. 



(d) The fiber showed marked variations in digestibility, in 

 common with all feeds of similar character. While it has been 

 generally held that nitrogenous feed stuffs do not aflect the 

 normal digestibility of the coarse fodders they supplement, 

 it certainly seems reasonable to conclude that the addition 

 of 200 to 250 grams of the distillers' grains to the hay
