A STUDY OF RATIONS FED TO MILCH COWS. yi" 
Still it is possible to set up certain feeding standards which 
may be followed with more or less actual advantage to the 
feeder. 
TABLE 6. 
Rations as fed by dairymen, and proposed standards. Digestible 
nutrients, per rooo pounds live weight, daily.

The table above gives a number of results of observations 
as to the rations actually fed by dairymen, and with them sev- 
eral feeding standards for milch cows. ‘They are intended to 
show the amounts of nutrients in the food per day and per 
thousand pounds of live weight of the animal. In each case 
the quantities represent the digestible nutrients and the fuel 
value of the daily ration. ; 
The first represents the average of 128 rations compiled by 
the Wisconsin Experiment Station.* The figures for the 
amounts of foods in these rations 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 quan- 
tities of food as given by the individual feeders were based
