312 - ReEporT OF THE CHEMIST OF THE 
c. AMouNT or CrEAM REQUIRED TO MAKE BUTTER. 
To make one pound of butter requires least cream in the case 
of the Jerseys. The amount of cream required to make a pound 
of butter will depend mainly upon two things, (Ist) the per 
cent. of fat.in the cream, and (2d) the loss of fat in churning. 
If 100 pounds of Jersey cream make a certain amount of butter, 
then the other breeds will require, in order to make the same 
amount of butter, the amounts of cream stated below:

d, Per Cunt. or Fat in Cream. 
The cream made from the milk of the Jerseys contained most 
fat. In the case of the other breeds, the amount of fat in the 
milk seemed to have no definite relation to the amount of fat in 
the cream. This is a somewhat uncommon experience, it being 
generally held that by the same method of creaming the richness 
of the cream in fat will vary with the richness of the milk in fat, 
The Guernseys stand second in respect to amount of fat in milk, » 
but their cream is least rich in fat. These averages are based | 
upon work extending over a period of ten months and every effort 
was made to secure uniform conditions in the creaming method 
employed. They can, therefore, scarcely be regarded as the result 
of some temporary and incidental irregularity either in the cows 
or in the methods of creaming. The Holstein milk stands fourth 
in respect to the amount of its milk-fat, while the cream stands 
second in richness of fat.
