REDUCING THE AMOUNT OF NUTRIENTS WHEN LESS THAN 15.5 LBS. 
The average data from 127 records, each of which covers a 
period when the amount of total nutrients, in no case exceeding 
15.5 lbs. per day per 1000 lbs. live weight, was reduced, are 
found in Table XVIII. The average reduction was a moderate 
one. The milk flow diminished somewhat more rapidly than is 
usual under a continuously favorable ration. The rate of gain 
in live weight was slow. 
With but little change of protein—The average of 67 records 
when there was but little change of protein with the moderate 
reduction of the total nutrients, shows a little less than the 
normal shrinkage in milk flow. Little increase in live weight 
occurred. (A, Table XVIII.) | 
With an increase of protein—tThere are 27 records in which 
there was a decided increase of protein in the ration. The aver- 
age shrinkage in milk was greater than normally occurs. There 
was little change in live weight. (B, Table X VITL.)
