energy furnished by the different foods, is explained on page 17 
of this Report. 
The weights of digestible nutrients in the rations were obtained 
from the weights of total nutrients by the use of factors (coeffi- 
cients of digestibility) obtained from the results of digestion 
experiments in this country and Germany. So far as possible, 
the factors obtained in American digestion experiments were 
employed. ‘The following tabulation gives the digestion coeff- 
cients here employed.

In order to show the range of variation from day to day in the 
feeding of the same herd, the minimum and maximum daily 
rations per 1,000 pounds live weight are appended to these tables. 
The size of the rations is here measured by the total energy of 
the nutrients (protein, fats, etc.) A ration which is large in total 
energy may have a small amount of a given kind of food or a 
given kind of nutrients. Hence it sometimes happens that the 
minimum of one of the nutrients furnished by a certain kind of 
food in a given ration may be greater than the average of the 
nutrients in that ration. This is the case with the minimum of 
the coarse food in ration 1, table 13. The same may happen 
conversely, in the case of the maximum.
