an increase of the total ntttribnts when more than 15.5 lbs. 



In Table XIV are the average data from 41 records when the 

 amount of total nutrients above 15.5 lbs. was increased. There 

 was on the average a slight increase in the amount of protein. 

 The diminution in milk flow following the change was consider- 

 ably less than usually occurs during the same time without 

 change in the ration. There was a good average gain in weight 

 before the change but not afterward. 



With an increase of protein. — Twenty-eight of the records in 

 each of which there was an increase of the protein show about 

 the same average results as all the above (B, Table XIV). There 

 was a good gain in weight before the change but some loss after- 

 ward. 



With a, rcdnction of protein. — Only 13 records show the increase 

 of nutrients with a reduction in the amount of protein. There 

 was but light shrinkage in the milk flow. There was a good 

 rate of gain in weight which became much slower after the 

 change. 



A REDUCTION IN THE AMOUNT OF TOTAL NUTRIENTS WITH BUT LITTLE 

 CHANGE IN AMOUNT OF PROTEIN. 



The average data from 82 records, each of which covers a 

 period when this change in the ration was made, are given in 

 Table XV. The average reduction of nutrients was only about 

 one pound. The shrinkage in milk flow was a little faster than 

 would usually occur. The moderate rate of gain in live weight 

 was not affected.
