Instead of allowing the market prices prevailing in different years 

 for grain, hay and other feedstuffs, it was thought it would be more 

 instructive to figure the cost at the prices prevailing during the past 

 four or five years. The price of grain is based on ton lots for cash 

 delivered at the feeding barn. Hay is supposed to have been grown 

 upon the farm and has been estimated at the market value in the 

 mow. It is believed that the prices are fairly representative. Some 

 may consider the estimated cost per ton of the silage too high. In the 

 station herd no silage has been fed since 1906. During the summer 

 when the cows were in milk they were fed on soiling crops, hay and 

 grain. This method naturally increased the feed cost somewhat. 



As a summary of Tables I and II we have the following : 



TABLE III. 



Average Cost of Grain and Roughage Per Com'. 



It will be seen that the average cost of food consumed per cow 

 was $90.04 and that the cost of grain was 37.4 percent of the total 

 cost.

*It is recognized that modern dairy barns, especially if built partly of cement, would cost 

 very much more. The above figure is intended more as an average for existing buildings. 



tLarge heavy milking cows, if purchased fresh at market centers, would cost from 

 $25 to ^35 more.
