Average Dry and Digestible Nutrients in Daily Hat ions {Pounds). 



First period: both herds, standard grain ration. 



The digestibility of the standard grain mixture was asccr- 

 lained by actual experiment. 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 

 ])onnds. In the first period the amount of digestible protein 

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

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

 protein than did Herd I.
