Digestion Experiments With Wethers. 41 



The average digestion coefficients as found for Wyoming 

 alfalfa havs are as follows : 



Wyoming alfalfa hay runs higher in crude fiber and crude 

 protein than the average. The digestion coefficients of the 

 crude protein is also high. The nutritive ratio of first cutting 

 alfalfa is i 13.19; second cutting for both years, 1 13. 68. Sec- 

 ond cutting alfalfa is apparently a better feed.
