During this experiment Bevkley was the only cow in the herd that 

 received protein in excess, of the amount prescribed in the Wolff-Lehmann 

 standard, while one other heifer, Reddy, received narly as much. Both 

 Reddy and Tricksey were heifers of about the same weight; the former 

 received 1.69 pounds of protein while the latter received 1.56 pounds, their 

 milk was of the same quality, but Reddy gave only 14.49 pounds daily 

 while Tricksey gave 15.73 pounds, indicating that the former at least, 

 received more protein than she needed for the milk she was giving. 

 During the 70 days, Reddy gained in body weight 38 pounds, while Trick- 

 sey gained 21 pounds. The heifers named and Quidee were making nor- 

 mal growth and it may be that the excess of protein fed was used in build- 

 ing the body. By comparing the quality of the milk yielded by each cow 

 as indicated in the column of per cent fat, with the amount of protein 

 charged to a pound of milk, we again find that of the mature cows work- 

 ing under normal condition, the cow that yielded milk containing 5.4 per 

 cent fat used .061 of a pound of available protein to a pound of milk 

 yielded, that the cows that yielded milk containing 3.7 per cent fat are
