Group 5 changed at the beginning of period 2 from the 

 preliminary ration to one containing only one half as much 

 ensilage, receiving in its place corn stover and corn and cob 

 meal. The stover and meal fed were from corn exactly like 

 that put in the silo, and as nearly as we could calculate the 

 amount fed was equivalent to the reduction in ensilage. In 

 period 3 the change from ensilage to dry stover and corn and 

 cob meal was made complete. In period 4 ensilage replaced 

 the stover and meal. 



Table 5. 



We have assumed that the digestible nutrients furnished in 

 the rations fed during periods 2 and 3 were equal in amount 

 to those fed during periods i and 4, but they may not have 

 been so exactly. The reduction in the amount of ensilage 

 fed in period 2 was accompanied with a slight shrinkage in 

 milk in the case of Maid of Arlis, not, however, more than 

 would have been expected if her ration had remained as 

 before; while in the case of Nora, 2d, there was a positive 

 increase of one quart per day. The effect of changing wholly 

 to dry food in period 3 was a shrinkage in the yield of Maid 

 of Arlis of nearly two quarts and in Nora, 2d, of nearly one 

 quart per day. The return to ensilage in period 4 kept the 

 yield of Nora, 2d, almost constant, while that of Maid of
