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 fuel value of 
the digestible nutrients (protein, fat, etc.) A ration which has a 
large fuel value 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 feeding stuff in a given ration may be greater than the aver- 
age of the nutrients in that ration. This is the case with the 
minimum of the coarse food in ration 23, table 8. The same 
may happen conversely, in the case of the maximum.
