FEEDING VALUE OF ALFALFA. 



115 



The analytical data are expressed in dry matter because of variations 

 in moisture. From an analytical standpoint the hays resemble each other 

 closely; the same may be said of the alfalfa, except that the sample in 

 the third experiment contained somewhat less fiber. The albuminoid 

 matter was determined by the Stutzer method, which includes both the 

 amino acids and the acid amids. In view of the fact that the amino acids 

 are supposed to be valuable in protein sjoithesis, the Stutzer method of 

 separation is not held to be of as much importance as formerly. The hay 

 contained 14.5 per cent, and the alfalfa 22.64 per cent, of its nitrogen 

 in the non-albuminoid form. 



The beet pulp used in the third experiment showed rather more fiber 

 and a little less extract matter, because of the lack of the molasses. 



The several lots of the different grains were quite uniform in character. 

 The one sample of gluten feed on which a non-albuminoid nitrogen test 

 was made showed some 29 per cent, of this ingredient, indicating the ad- 

 dition of considerable "steep water" in its manufacture.
