In this experiment 5 pounds were fed to begin with, and this 
quantity increased 5 pounds even 7 two days up to 20 pounds, when 
it was reduced to 5 pounds again, dropping 5 pounds every two days. 
It was observed that the alfalfa-silage flavor did not become notice- 
able in the milk until 10 pounds or more were fed. However, when 
from 15 to 20 pounds were consumed at each feeding the milk took 
on a decided feed flavor and odor. 
When this milk was aerated the degree of feed flavor and odor 
was decidedly reduced and was detected less often, as shown in the 
table. This again shows the importance of aerating milk. It was 
also observed that when the milk from cows receiving 10 poimds was 
aerated all judges failed to detect feed flavors or odors. 
This work indicates that alfalfa silage should be fed only after 
milking, and that the milk should be well aerated while still warm. 
The importance of this is shown by comparing the results in Table 7 
with those obtained in Table 8. 
EXPERIMENTS WITH SWEET-CLOVER SILAGE. 
In some cases clover crops have been made into silage with fair 
success. Where weather conditions interfere with the proper curing 
of clover for hay it is sometimes put into the silo. It is well known 
that the silage made from clover has a strong odor, necessitating care- 
ful feeding to avoid tainting the milk. For this experiment silage 
made from sweet clover, cut in fine lengths and tramped solidly, 
was fed to the experimental cows. It was noted that the sweet- 
clover silage had a more decided odor than the alfalfa silage. 
1. FEEDING SWEET-CLOVER SILAGE BEFORE MILKING. 
At the beginning of the work 5 pounds of sweet-clover silage were 
fed one hour before milking. This was continued for several days ; 
afterwards the quantity was increased to 10 pounds and continued 
for several davs longer ; then increased to 15 pounds. An effort was
