New York AGRICULTURAL EXPERIMENT STATION. 203 
The amount of milk required to produce a pound of butter in 
the several periods was approximately the same. The amount of 
cream required varied somewhat for the periods. It is interesting 
to note that with an individual cow the variation in the amount of 
cream required for one pound of butter was very marked, ranging 
from 2.33 pounds to 3.36 pounds. Ripening the cream and churn- 
ing was always as nearly the same as could be secured in the 
Station dairy. The amount of cream for one pound of butter for 
this cow is considerably less than the average of the herd. 
Another point observed, thatit was necessary to raise the tempera- 
ture for churning with each change of grain as the period of lacta- 
tion advanced. In the first period the churning being made at a 
temperature of 58° to 60° Fahr. while in the last period for the 
same results the cream was churned at 64° to 65° Fahr. . 
While the actual costs of the rations as fed are given, yet these 
haye little significance as compared with the relative feeding value 
of the several foods. From the trials made with this animal, it is 
evident that gluten meal was a superior food for milk production. 
A digestion experiment at the close of the fourth period pre- 
vented repeating the first period with corn meal to determine how 
much change had taken place due to advance in lactation. Work 
with the digestion experiment, and absence from the Station, pre- 
vented a further study of the butters for which purpose the 
experiment was more specially designed. 
FEEDING EXPERIMENTS WITH Cow Fora. 
A feeding trial, similar to that with Nellie, was carried on with 
the Jersey cow Flora, but we were at the time unable to make the 
necessary analyses and so only as to the effect on the milk yield 
can we compare the foods tested. Flora dropped her last calf 
December seventeenth and was removed to the experimental barn 
December twenty-sixth at which date the feeding trial began, and 
continued until February twenty-second, when a change in the 
rations was made to deterfnine the digestibility of alfalfa hay. 
The time was divided into four periods of like feeding as follows :
