The most obvious effects of the rations fed as shown in the above 
tables was to considerably increase the quantity of milk given, and 
in a still greater degree to reduce its quality, especially for the pur- 
purpose of butter production. This is evident not only in the di- 
minished per cent. of fat in the milk and of butter obtained, but in 
the total amount of butter per day. 
The average per cent. of fat found in 130 previous trials of Jem’s 
milk at the Station has been 6.16, and of 76 trials made at about 
the same time after calving as in this test, and when the yield of 
milk was nearly as large was 5.26. The per cent. of butter calcu- 
lated on the same basis as those in this test, in 122 previous trials, 
has averaged 6.62. In view of these facts, and the large yield of 
butter obtained in the few trials made early in March, it seems fair 
to attribute the smaller yields of the above test to the ration fed. 
By comparing the yields of butter and the ratio of albuminoids to 
the remainder of the ration, it will be seen that the yield of butter 
has diminished quite regularly as the proportion of albuminoids has 
increased. This is clearly shown in the next table, where these are 
brought together.
