Conclusions. 



1. Soj bean meal partially extracted (2.3 pounds per day 

 and head) seemed to be without influence in changing the pro- 

 portions of the several milk constituents or in imparting any 

 flavor to the milk. 



2. Soy bean oil (.6 of a pound per day and head) was like- 

 wise without influence on the composition and flavor of the milk. 



3. Soy bean meal did not modify the chemical character of 

 the butter fat, neither did it have any effect upon the separation 

 of the fat from the milk serum, the time of ripening of the 

 cream nor on the thoroughness of the churning. Expert butter 



Partially extracted.
