There appears to be a marked difference in the digestibility of 

 middlings and roller bran, as shown by the results of this experi- 

 ment. A direct comparison of the two sets of figures is interesting.

Result of Experiment. 



(1.) This roller bran appears to have been slightly less 

 digestible than the Alsike clover or early-cut Timothy hay. 



(2.) In this experiment the digestible organic nutritive mate- 

 rial in a fine sample of middlings and in roller bran was found to 

 have the relation of 123 to 100. In other words, sheep digest- 

 ing their food as they did in this experiment would get as 

 much nutriment from 100 pounds of the middlings as from 

 123 pounds of bran. 

 (See further on for feeding experiment with middlings and bran.)
