COST OF THE FOOD. 



The foods which Maine farmers feed to their cattle generally 

 comprise those grown on the farm and those purchased. In es- 

 timating the cost of feeding an animal, two methods are adopted, 

 viz. : the home raised food is reckoned at what it costs to produce 

 it and the purchased foods at cost price, or all the materials con- 

 sumed, both home raised and purchased, are reckoned at what they 

 are worth in the market. 



The latter method is necessarily the one adopted here. If the 

 Station had produced the hay and grain given to these experimen- 

 tal cows, it would have been both valuable and interesting to 

 have kept a careful account with each crop for the purpose of as- 

 certaining the actual cost of feeding farm animals from home 

 raised foods. The method of adopting market prices answers 

 every purpose in this case, however, as it is largely a question of 

 comparative cost. 



Again, the prices adopted must be somewhat arbitrary, as they 

 always fluctuate during a year. An attempt has been made to 

 approximate quite closely to the average market prices for the 

 first year during which this test has been parrie4 on,
