Digestibility of Bihhy's Da ivy Cal-e. 



The average results of six single trials with sheep are here 

 given, together with the coefficients for standard wheat mid- 

 dlings and gluten feed for comparison. The full details of 

 the digestion experiment have been reported in the seven- 

 teenth report of this station.

In the several trials Avith Bibby's dairy cake the sheep 

 experienced considerable difficulty in digesting the crude 

 fiber, due probably to the fact that it was derived largely 

 from cotton-seed hulls. It may be said that the total cake 

 proved moderately digestible, the fiber having a low and the 

 fat a high digestibility. Both in chemical composition and 

 in dig(?stibility Bibby's dairy cake closely resembled standard 

 wheat middlings. Gluten feed contains 5 to (> \)vr cent, 

 more protein, and is more digestible than the cake.
