Cost op Milk Pkoditotion. 



87 



As a sort of side issue a stiidy was made of the effect of a grain 

 ration upon the cost of production of milk and fat. The study was 

 made during the month of June in this way. The cows were first 

 turned to pasture on May ninth; the winter grain ration of eight pounds 

 per day was reduced to the summer ration of four pounds per day on 

 May twenty-six; on June third the cows were divided into two lots, 

 evenly mated as nearl}^ as possible in regard to the yield of milk, age, size, 

 time of calving, etc. One lot received no grain during the remainder 

 of the month of June; the other lot continued to receive the customary 

 allowance of four pounds.
