A REDUCTION OF THE PROTEIN WHEN MORE THAN 2.5 LBS. 
One hundred twenty-three records when there was this reduc- 
tion of protein give the average data found in Table XXXVI. 
The average yield of milk diminished at about half the normal 
rate. The rate of increase in live weight, at about one-half 
pound per day, was not affected. 
With little change in amount of nutrients—When there was 
little change in the amount of nutrients in 31 instances the 
average result shown in A of Table XXXVI was obtained— 
which was practically the same as the total average above 
given. 
With an increase of total nutrients——In 47 instances, when an 
increase of total nutrients occurred, there followed no reduction 
in the milk yield, but a slight average increase. The rate of gain 
in weight from about one-half pound per day became about one 
pound per day. (B, Table XXXVI.) 
With a reduction of total nutrients.—When there was a moder- 
ate reduction in the amount of total nutrients there followed,
