88 REporT OF DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
AN INCREASE OF THE TOTAL NUTRIENTS WHEN MORE THAN 15.5 LBS. 
In Table XIV are the average data from 41 records when the 
amount of total nutrients above 15.5 Ibs. was increased. There 
was on the average a slight increase in the amount of protein. 
The diminution in milk flow following the change was consider- 
ably less than usually oecurs during the same time without 
change in the ration. There was a good average gain in weight 
before the change but not afterward. 
With an increase of protein.—Twenty-eight of the records in 
each of which there was an increase of the protein show about 
the same average results as all the above (B, Table XIV). There 
was a good gain in weight before the change but some loss after- 
ward. 
With a reduction of protcin.—Only 13 records show the increase 
of nutrients with a reduction in the amount of protein. There 
was but light shrinkage in the milk flow. There was a good 
rate of gain in weight which became much slower after the 
change. 
A REDUCTION IN THD AMOUNT OF TOTAL NUTRIENTS WITH BUT LITTLH 
CHANGD IN AMOUNT OF PROTEIN. 
The average data from 82 records, each of which covers a 
period when this change in the ration was made, are given in 
Table XV. The average reduction of nutrients, was only about 
one pound. The shrinkage in milk flow was a little faster than 
would usually occur. The moderate rate of gain in live weight 
was not affected.
