INFLUENCE OF STAGE OF LACTATION. 131 
pounds of net nutrients and a pound of milk solids to 1.07 
pounds of nutrients. Her decrease in weight was more 
gradual and continued during the 11 weeks when she had 
lost 100 pounds. She did not sacrifice so much in weight in 
any one week as did Trust, nor did she yield products so 
much in excess of nutrients consumed. This was due to her 
temperament—not being so pronounced a dairy type. She 
is not as great a feeder as Trust and after the 5th week had 
reached her normal ration. As her weight decreased the 
nutrients required to a pound of product increased, but she 
had not by the close of the 11th week reached an equilibrium 
between the in-go of nutrients and out-go of product, for 
under normal conditions it requires over 6 pounds of nutri- 
ents to a pound of butter fat and about 2.45 to a pound of 
milk solids. During the 77 days covered by the record she 
lost on an average 1.4 pounds per day and had not reached 
her normal working weight.
