With but little change in total nutrients —The amount of total 
nutrients was but little changed in 43 instances. The milk flow 
diminished at a little more than the usual rate. The average 
increase in live weight was considerably greater after the 
change. 
With some reduction of nutrients—The average for 22 instances, - 
when considerable reduction in amount of nutrients occurred, 
shows a falling off in milk twice as great as is usual. The gain 
in live weight was much less after the change of ration. 
A REDUCTION OF THH PROTEIN WHEN LESS THAN 2 LBS., MORB THAN 
1.6 LBS. 
The average data from 55 records when such a reduction 
occurred are found in Table XXXIX. The average shrinkage 
in milk was at about twice the normal rate. There was but 
little change in live weight. 
With but little change in amount of nutrients—After this change 
in the ration, when the amount of nutrients was but little 
affected, there was, on the average in 26 instances, a reduction 
of milk yield considerably greater than should normally occur. 
The data are in A of Table XXXIX. 
With some increase in amount of nutrients—Only 11 records 
cover periods when with such a reduction of protein the nutri- 
ents were increased. In these cases the amount of total nutri- 
ents was small, and there was a continual loss of live weight. 
The milk flow diminished but little faster than usual. There 
was some increase in the cost of production. 
With some reduction in amount of nutrients —There are only 
18 of the records which show this change of ration. In these 
the shrinkage in milk flow was at about three times the normal

REMARKS, 
In general changes in the amount of protein within the ordin- 
ary limits produced less effect than changes in the amount of 
total nutrients. The average results which followed the differ-
