AN INCREASE IN AMOUNT OF NUTRIENTS TO NOT MORB THAN 15.5 LBS. 
The average of 111 records, in each of which there was an 
increase in the amount of nutrients to not exceeding 15.5 Ibs. 
per day per 1000 Ibs. live weight, is shown in the following table. 
The average inerease in nutrients was slight but the usual 
shrinkage in milk flow did not occur. In 61 instances there was 
a decided increase of protein in the ration, in 24 instances a 
decided reduction and in 26 instances little change. There was 
but slight average gain in live weight. 
— With but little change in amount of protein—The average of 
the 26 records in which little change in the amount of protein 
occurred shows a trifle less than the usual diminution of milk 
yield expected at this stage of lactation. The average increase 
in amount of nutrients was but little. A slight loss in live 
weight occurred. See A in Table XII. 
With an increase in the amount of protein.—Sixty-one records 
show a slightly greater average yield of milk following the mod:
