EXPERIMENT ITI. | 
In this experiment hay, like that used in the last ration, and 
turnips were fed. The results appear in the next table.

The nutritive ratio in the above ration proves to be 1: 19.1. 
Further we observe that the digestibility of the albuminoids of 
the hay are considerably depressed, but that the nitrogen-free 
extract is more fully digested than was the case with the last. 
Roots 1n 4 Ratton. 
Influence on the Albuminoids.—It has long been the opinion, 
based on German investigations, that roots and tubers fed in 
connection with coarse fodders decrease the digestibility of the 
albuminoids and crude fiber of the coarse fodders. 
This last digestion experiment afforded an opportunity to make 
some investigations on this particular point. Assuming that the 
ratio of digestibility for the hay was the same, or approximately 
so, for the several animals in the trials, and had Star digested her 
hay equally as well in the ration of hay and turnips as did Spot 
when fed the same hay alone, then there should have been digested 
7.1 ounces of albuminoids plus the albuminoids of the turnips, 1.3 
ounces, or a total of 8.4 ounces of albuminoids should have been 
‘digested for the ration. In reality only 6.3 ounces of the total 
albuminoids were digested or 0.8 ounces less than should have 
been digested in the same amount of hay fed alone. In our trial 
then the influence of the roots seems to have been to decrease the 
digestibility of the albuminoids of the hay. 
INFLUENCE ON THE CRUDE Fiser AND NITROGEN-FREE EXTRACT. 
Assuming, as has been customary, that roots are completely 
digested, we find Star should have digested from the hay 29.7
