+ 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 
observations of the feeding practices of the best German feed- 
ers, 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 by Prof. Woll to ‘“‘dairy 
farmers and breeders of dairy stock in all parts of the United 
States and Canada, asking information concerning their meth- 
ods of feeding milch cows.’’ ‘The author says, ‘“‘It is hoped 
that the very varied conditions of feeding represented in the 
rations reported from the different regions of our large country 
will suit the cases of one and all American dairymen striving 
to improve their system of feeding so as to produce the largest 
quantity of dairy products at the least possible cost of foods.’’ 
The results of the inquiries are summarized in the statement, 
“Combining all of the above 128 rations which have been fed 
by successful dairy farmers and breeders in various parts of
