 the experiment was begun the cows were not fed as much as they 

 ought to receive. The results obtained are given in the following 

 table.

These figures show that an increase in the grain ration from 

 two pounds to 24 pounds per cow per day did not change the aver- 

 age test of the milk of these cows, even though the heavy grain 

 feeding was continued for nearly four months. There was an in- 

 crease however, in the flow of milk amounting to three pounds of 

 milk per day for cow No. i and five pounds and six pounds per day

It will be noticed that the milk flow of each cow increased on 

 the heavy grain ration for about 60 days, that there was then a 

 slight falling off for about 60 days, and a decided decrease in milk
