142 REPORT OF THE CHEMIST OF THE | 
DIGESTIBILITY. 
In a feeding trial made at the Station during the past winter 
the digestibility of alfalfa hay was determined. The subject for 
experimentation was a four-year-old Jersey cow, in milk about two 
months when the trial was made. February twenty-third the 
feeding of alfalfa hay was begun, twenty-five pounds per day were 
offered and during the five days on which the dung was saved, an 
average of 24.31 pounds or 389 ounces per day were eaten. The 
amount of dry matter consumed per day was 322.7 ounces. From 
noon of March fourth until noon of March ninth, five days, men 
were constantly with the animals and all excreta was received in 
pails and at once transferred to large vessels, kept closed to pre- 
vent loss by evaporation. At the end of each twenty-four hours 
the dung was carefully mixed, sampled, and taken to the labora- 
tory for analysis. 
All food was weighed and the unconsumed hay for the day 
weighed back and sampled. This waste was kept in a large glass 
jar and at the end of the period analyzed, but as the details are 
uninteresting and unessential to discussion of results only a sum- 
mary of all is given in the following table:
