weight before and a gain after the change of ration (B, Table 
X XIX). 
With a reduction of nutrients—In only 9 of the records there 
occurred, with this same increase of protein, a reduction in the 
amount of total nutrients. In these few instances there was a 
rapid diminution of milk flow with a much greater cost of pro- 
duction. 
AN INCRBASE OF THE PROTEIN WHEN ABOVE 2 LBS. AND LESS THAN 
Oz es, 
There are 56 records which cover periods when this change in 
the ration was made. There followed a diminution of milk flow 
at a little less than the normal rate. The gain in live weight, 
fairly good before, was very little after the change. The data 
are found in Table XXX. 
With an increase of nutrients —After an increase of protein, 
with an increase in the amount of nutrients, in 28 instances 
there followed very much less than the usual diminution in 
milk flow. There was a good rate of increase in live weight 
before but a moderate loss after the change. See B in Table 
XXX. 
With a reduction of nutrients—When, with the increase of pro- 
tein, there was a reduction in amount of nutrients in 28 in- 
stances, the following decrease in milk production was at a 
faster rate than normal. There was a good rate of gain in 
weight, but slower after the change. . 
AN INCREASE OF PROTEIN WHEN BETWEEN 2.25 LBS. AND 2.5 LBS. 
The average data from 72 records which cover periods when 
this increase in protein content was made are found in Table 
XXXII. The milk flow diminished but very slightly. The live 
weight increased on the average faster after the change than 
before. 
With an inerease of total nutrients.—Thirty-two records cover 
periods when with the increase of protein there was an increase 
of total nutrients. The milk yield was very slightly increased. 
There was a loss in live weight before the change and a con- 
siderable gain afterward.
