THE AMOUNT OF NUTRIPNTS BUT LITTLE CHANGED WHEN BELOW 
15.5 LBS. 
The average for 84 records when the amount of nutrients, less 
than 15.5 lbs. per day per 1000 Ibs. live weight, was but little 
changed, gives the data in the following table. There was no 
change, on the average, in the amount of protein. The shrink- 
age in milk flow was considerably less than usually occurs. 
There was the same moderate rate of gain in live weight before 
and after the change of ration.
