No general statement regarding the influence of advancing lac- 
tation upon the amount of milk required to make a pound of 
butter can be made that will hold true of all the breeds. When 
the amount of fat in the milk increases, less milk is required,to 
make a pound of butter, provided the increased amount of fat is 
not lost in the skim-milk and buttermilk. In the case of the 
Ayrshires, the amount of milk required to make a pound of butter. 
gradually increases with advancing lactation; with the other 
breeds, the tendency appears to be a slight fluctuation about a 
certain point or else a tendency to a slightly diminished amount | 
of milk for making butter. 
In regard to the influence of advancing lactation upon the 
amount of milk required to make a pound of cream, the amount 
of cream required to make a pound of butter, and upon the per 
cent. of fat in the cream, it is impossible, from the data in hand 
to make any general statement. Such variations as there are 
appear more or less irregular and are not very marked. |
