These figures show that during the time when ensilage was fed, 

 63 days, the cows maintained an average yield somewhat greater 

 than from the previous exclusive hay and grain feeding, even 

 though a decrease in milk flow would ordinarily have taken place. 

 When a return is made from hay and ensilage to hay alone, a sud_ 

 den and decided drop in production occurs.
