^ The carbohydrate equivalent is the sum of the digestible carbohydrates plus 2.25 times 

 the digestible fat. 



^ Rations based on the initial weights of the calves. 



From Table 4 it is seen that the ration given Lot 3 provided con- 

 siderably more dry matter than the rations given Lots 1 and 2, the 

 two latter being nearly the same. Lot 3 also received more total 

 digestible nutrients than the other two lots. 



GAINS DURING WINTER. 



The gains and losses in weight during each of the three winters are 

 shown in Table 5.
