Digestibility of Distillers' Grains. 

 Digestion tests were made with sheep, and the following 

 co-efScients obtained : — 



Excepting the "E." 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: —

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

 tity of digestible nutrients as does wheat bran. The latter 

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

 matter dio-estible than the former.
