First period: both he(;ds, standard grain ration. 



The digestibility of the standard grain mixture was asccr- 

 lained by actual exi)erinient. Average coefficients were used 

 for the other feeds. Both herds received substantially the 

 same amounts of protein and total digestible nutrients in the 

 first period. Each herd averaged in live weight about 950 

 pounds. In the first period the amount of digestible j^rotein 

 was ample to enable the cows to do good work. In the second 

 period Herd II. received .86 of a pound more of digestible 

 protein than did Herd I.
