The nutritive ratio in the last ration proved to be 1:43. 
Assuming that Broad digested the hay in this ration equally as 
well as did Spot, when fed hay alone, then we may calculate the 
per cent digested from the grain ration as fed. These results are 
given in the following table:

Whitey receiving a ration made up from grain foods, more 
largely carbonaceous, consumed per day as follows: Hay, 8.83 
pounds; wheat bran, two pounds ; corn meal, ten pounds. In the

such a ration: .

The nutritive ratio for the ration fed Whitey proved to be 1:8.6, 
just twice as wide a nutritive ratio as in Experiment LY. 
As with Broad, assuming that the hay was digested in the same 
proportion in this ration as when fed alone, we calculate the 
digestibility of the grain ration as follows :
