146 REPORT OF THE CHEMIST OF THE 
ounces and from the turnips 1.6 ounces or a total from the ration 
of 31.3 ounces. There was digested 34.4 ounces or 3.1 ounces 
more than should have been digested from the same hay fed 
alone. Of the nitrogen-free extract there should have been 
digested 45.2 ounces from the hay, 7.7 ounces from the turnips, 
a total of 52.9 ounces, but the amount actually digested was 54.8 
ounces, so that 1.9 ounces more was digested from the hay than 
would have been estimated. We may conclude that our results 
are seemingly in accord with the German: 
1. That roots when fed in a ration tend to decrease the digesti- 
bility of the albuminoids of the coarse fodders. 
2. That the influence of the roots on the nitrogen-free extract 
of the fodder was to increase the digestibility. 
WHAT Is THE ADVANTAGE OF FEEDING Roots? 
If the addition of roots to a fodder decreases the digestibility 
of the albuminoids, considered the most valuable portion, then 
where is the great value to be derived from their use in a ration? 
At first this would seem to indicate little or no value for roots 
and such would be contrary to general observation. Their value, 
when fed in aration in moderate quantities, over dry fodder or 
grain seems, like silage, to be in their power to act as a corrective 
of the system, thus enabling the animal to put to better use the 
portion of the food already digested. In other words it prevents 
the system from becoming clogged, gives tone and vigor to the 
animal and enables the assimilated food to be used with economy. 
Experiment IV. 
As stated, Broad’s ration consumed was: Hay, 8.79 pounds ; 
wheat bran, seven pounds; corn meal, four pounds, and cotton- 
seed meal, three pounds. The next table shows the amounts eaten
