Digestibility of Distillers' Grains. 

 Digestion tests were made with sheep, and the following 

 co-efficients obtained :. — 



Excepting the "R" brand, these materials show relatively 

 high digestibilities, with comparatively small variations. In 

 the last column is given an average of the four "X" 

 brands, which may represent the average digestibility of dis- 

 tillery grains made largely from corn. 



Multiplying the composition by the percentages digestible, 

 one obtains the percentage or pounds in 100 digestible: — 



constituents.

The " R" brand appears to contain about the same quan- 

 tity of digestil)le nutrients as does Avheat bran. The latter 

 contains rather more protein, and a trifle less fat and extract 



matter digestible than the former.
