NATIVE HAY. 

 EXPERIMENT IV. 



The first experiment with native hay was conducted with 

 some Western Wheat Grass (Agropyron occidentale) from the 

 ranch of Mr. M. A. Crout, under the Pioneer Canal, near Lar- 

 amie. The fodder was comparatively free from foxtail, and 

 contained only now and then a few stems of other native hays. 

 The hay was not a first-class sheep hay, being over ripe and 

 woody. After the experiment was well under way one sheep 

 broke from his stall, ate some other feed, and in a general man- 

 ner carried on the experiment to his own satisfaction, so that 

 the results obtained from one sheep only are given. 



The sample of feed for analysis was divided into two lots, 

 each thoroughly mixed, and analyzed with the following re- 

 sults : 



Nitrogen- 

 Ether Crude Crude free 

 Water Ash extract fiber protein extract 



First 6.05 6.47 2.82 29.70 6.81 48.15 



Second 5.84 6.00 2.54 29.26 6.88 49.48 



Average 5.94 6.23 2.68 29.48 6.85 48.82 



The hay was not eaten well by the wether, many grass 

 heads and much seed being left.
