INDIVIDUALITY OF COWS AND SHEEP AS TO THE AMOUNT OF 



SILAGE DIGESTED 



An inspection of the tables shows that the three cows and three sheep 

 all varied considerably in the amount of dry substances digested. In 

 general, the same ratio of dry substance digested and nutrients absorbed 

 existed. The sheep showed a much larger variation in total dry matter 

 digested than was noted with the cows. The results of this one diges- 

 tion period indicate that there exists an individuality among animals 

 as to the thoroughness with which they digest their feed. This view is 

 supported by the recent work of Grindley l and his associates on diges-
