INFLUENCE OF STAGE OF LACTATION. 137 
The foregoing table covers the record of the daily aver- 
age for each week beginning with the 119th week of lacta- 
tion to the close of the 132nd week. While there was some 
variation in the weight from week to week there was no 
marked gain or loss. Twice her feed was reduced, the 122nd 
and 125th, the latter time it covered two weeks. The 127th 
it was again raised and for 28 consecutive days there was 
nochange. It was then raised and the week following it 
was again found necessary to reduce it. She maintained her 
flow in milk but there was aslight decrease in butter fat. 
When her feed was lowered she used less than the normal 
amount of nutrients, about 6 pounds, to a pound of butter 
fat yielded. During the 131st week of lactation when her 
feed was raised, she returned a pound of fat to 7.57 pounds 
nutriment and did not increase in yield of fat, but the week 
following there was a slight increase. Notwithstanding 
that the record covered a period from the 119th to the 
132nd week of lactation she required only 6.21 pounds of 
nutriment to a pound of butter fat and 2.47 to a pound of 
milk solids being the normal amount required by cows when 
no change in body weight takes place.
