not even enough to pay for all the food consumed. This was 

 the case with cows producing less than four thousand pounds 

 of milk. 



In comparing the columns, "Pounds of Milk Produced" 

 with the column "Cost of Producing 100 pounds of Milk," it 

 will also be seen that there is a definite relation of yield to 

 cost of production. With an increase in the amount of milk 

 •produced, there is a gradual decrease in the cost of milk pro- 

 duction. The tabulated results of 996 cows from four different 

 cow test associations in the state showed similar results. Al- 

 though there may be single exceptions to the rule, it is safe to 

 aay that, under average conditions, the food cost per 100 

 pounds of milk is decreased with an increase in the amount of 

 milk produced. 



This does not only appear to be true under average condi- 

 tions, but similar results were obtained under conditions where 

 cows were fed probably with very little regard as to the cost 

 of production but rather to produce as much milk as possible, 

 without regard to cost. The table below is taken from Hoard's 

 Dairyman, Jan. i, 191 5, and the figures are compiled from data 

 collected in the Wisconsin Cow Competition of 1911, where a 

 prize of $i,ooo was offered to the owner of the highest pro- 

 ducing cow in the state of Wisconsin. In the table is included 

 157 cows — pure bred Holstein cows.
