THE AMOUNT OF NUTRIENTS 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 lbs. live weight, was but little 

 changed, gives the data in the following table. There was uo 

 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.
