So far as an experiment of this kind can furnish reliable evi- 

 dence, we have reason to believe that there was practically no dif- 

 ference in the feeding value of this two lots of hay. This is 

 what might be expected after finding that the hay had so little 

 difference in composition and digestibility, and may be considered 

 as adding to the constantly accumulating evidence that the rela- 

 tive value of fodders can be ascertained quite closely without an 

 actual feeding trial. 



It is rarely the case, however, that early and late-cut hays show 

 so little difference in composition and digestibility, and so the re- 

 sult here recorded should not be considered as representative. 



An Experiment for Comparing the Feeding Value of Wheat 

 Middlings and Wheat Bran. 



The values of wheat middlings and wheat bran, when judged by 

 composition alone, do not seem to be greatly different. As proof 

 of this, the average composition of seven samples of middlings 

 and six samples of bran as given on page 59 of this report, are 

 cited here.

A determination of the digestibility of the middlings and bran 

 with sheep(see page 64 of this report) revealed the fact that as much 

 was digested from 100 lbs. of middlings as from 123 lbs. of bran. 

 This indicated quite a difference in feeding value, and it only re- 

 mained to test the matter by ascertaining whether in an actual 

 feeding trial with these two foods growth would be obtained in 

 proportion to the digestible matter which they seemed to furnish. 

 There were used for this feeding trial four swine weighing about 

 200 lbs. each. Previous to the time when this experiment began 

 these animals had been eating a ration of skimmed milk and corn
