ble matter as the low-protciii cows. Tlio amount of food fed 

 daily to each cow was gauged partly by the appetite of the 

 animal. The high-protein cows received only .44 of a pound 

 more digcslihlc protein than the other herd. 



Influence of Ilaiions on Weight {Pounds). 



The cows receiving the low-protein ration gained rather more 

 in weight than the other herd ; whether this wa.s due to the 

 character of the ration, or whether it simply depended upon 

 the individuality of the animal, it is difficult to say. 



True^ Protein Balance {Pounds). 



The high-protein cows received an average of 28 per cent, 

 of protein over maintenance and milk requirements, while in 

 case of the low-])rotein cows the percentage varied from an 

 actual shortage of 4.5 per cent, to a surplus of 10.5 per cent: 



' Amines were determined and deducted from the total protein, the above results being ex- 

 pressed as true albuminoids.
