 milk yield. The rate of increase in live weight was noticeably 

 reduced. 



A REDUCTION OF THE PROTEIN WHEN ABOVE 2.25 AND LESS THAN 



2.5 LBS. 



The only records available which show this reduction of pro- 

 tein show a corresponding reduction of the total nutrients; 54 

 records give, following this change in the ration, an average 

 reduction in the milk flow about three times as great as should 

 occur at the same stage of lactation. There was some loss in 

 live weight but much less before the change of ration than after- 

 ward.

BkTWEEN 2.25 AND 2.5 Ebs. 



A REDUCTION OP THE PROTEIN WHEN ABOVE 2 LBS., UNDER 2.25 LBS. 



The 65 records which cover periods when this change in the 

 ration was made show an average decrease in milk flow consider- 

 ably greater than it should normally be. There was a very good 

 increase in live weight.
