+ In this suggested ration the fuel value could be supplied by about .5 of a pound of digest- 
ible fat and 13.0 pounds digestible carbohydrates; by .6 of a pound of digestible fat and 12.5 
pounds of digestible carbohydrates; or by .8 of a pound of digestible fat and 12 pounds of 
digestible carbohydrates. 
The German figures in the above table are based upon ob- 
servations of the feeding practices of the best German feeders, 
and a large number of feeding experiments conducted by trained 
specialists, chiefly in experiment stations. 
The 128 rations compiled by the Wisconsin Experiment Station 
were obtained in response to letters sent to “dairy farmers and 
breeders of dairy stock in.all parts of the United States and 
Canada, asking information concerning their methods of feeding 
milch cows.” ‘The average of these rations represents the aver- 
age of the feeding practice of American dairymen as ascertained 
from the more or less accurate estimates of the feeders them- 
selves as to amounts fed, etc. ‘The materials fed were not 
analyzed, but their composition was assumed from the averages 
of other analyses. ‘The Wisconsin Station proposes* this average 
as an ‘American standard ration for dairy cows.” 
The Connecticut rations given in the table represent the actual 
feeding practices of the dairymen whose herds were examined, 
so far as could be learned by weighing the foods actually fed
