A REDUCTION OF PROTEIN WITH LITTLE CHANGE IN AMOUNT OF 
NUTRIENTS. 
One hundred records which cover periods when there was a 
reduction of the protein with little change in amount of nutri- 
ents give the average found in Table XXXIII. Following this 
change there was just about the normal decrease in milk yield. 
The moderate rate of increase in live weight was slightly 
increased.

A REDUCTION OF PROTEIN WITH SOMP INCREASE IN AMOWNT OF 
NUTRIENTS. 
The average for 58 records when this change in the ration 
was made is shown in the following table. The accompanying 
reduction in milk yield was slight, much less than would nor- 
mally occur for a similar period. The live weight increased 
much faster after the change.
