42 Wyoming Experiment Station. 



The native hays of Wyoming are better and more nutri- 

 tious than timothy grown in the eastern states. 



The digestible nutrients in 100 pounds of hay are given 

 below calculated from the experiments described in this bul- 

 letin :

The water soluble of material was determined in the alfalfa 

 and native hays with the following results : 



Total water Total organic 



extract Ash matter 



Alfalfa, average 27.43 5.93 21.50 



Western Wheat Grass 22.23 2.58 19.65 



Native hay 18.84 3.79 15.05 



Alfalfa gives a larger water soluble extract than either 

 Western Wheat Grass or native hay. This may in part ac- 

 count for the fact that the alfalfa is more susceptible to fer- 

 mentation and decay upon dampening during the process of 

 curing than the other hays experimented with. As is well 

 known, it blackens oftentimes after a heavy dew.
