The result of this was to slightly but constantly increase 

 the cost per quart of milk. 



Period i6 marks a radical change of food and a sudden 

 falling ofif of milk flow, amounting to nearly 22%. The food 

 for this period was early cut herdsgrass hay, clover mixture, and 

 the same grain mixture as previously fed. So radical a change 

 from succulent food to dry fodder might naturally be expected 

 to cause a shrinkage out of proportion to the actual fall of feeding 

 value of fodder, but it will be noticed that although the cows 

 were fed all they would eat yet there was but 10)^ pounds eat- 

 en daily,v which, at the prices adopted for estimating values 

 makes the cheapest daily ration fed so far as actual cost is 

 concerned. The shrinkage was so great that financial consid- 

 erations induced us to change the ration at the end of a single 

 period back to the former ensilage ration, and by so doing the 

 yield was brought back by half the amount of the previous 

 shrinkage. 



At this point the ensilage gave out and in its place a ra- 

 tion containing cured corn fodder was substituted, also a large 

 addition was made to the grain portion of the food. A sub 

 stantial increase of milk was the result.

This shows a moderate increase in live weight throughout, 

 though in Period 8 the effect of the cold weather is indicated by 

 a shrinkage. 



Cut 2 shows by .a curved line the daily yield per period of 

 the ten cows whose individual record was kept, and also by a!n- 

 other curve, the price per quart of milk. This last is important, 

 showing as it does the financial side of the whole work. 



COST OF PRODUCING MILK. 



Commencing at Period one we find the cost to be i .65 

 cents per quart. Changing onto Southern ensilage increases, 

 this to 1.86 cents, and in our efforts to restore the loss of yield
