Butter Tests. 



[JULY, 



striking manner the observations on such variation arrived at 

 by chemical analysis. On the average we see that 19*09 lb. or 

 a little under 2 gallons of Jersey milk, and 27-92 lb. or about 

 2f gallons of Shorthorn milk have been required to produce 

 I lb, of butter. 



The first question that arises is whether this has any practical 

 application? Assuming the average price of butter to be is.

A butter ratio of 20 is worth 6d. per gallon.

These figures only take into account the value of the butter 

 contents of the milk, the value of the separated milk not being 

 included. Assuming the latter to be worth id. per gallon, that 

 amount should be added to each of the above figures, the 

 corrected amount thus representing the value for butter-making 

 purposes of the above samples of milk. 



We see that on the average 27*92 lb. or say 2| gallons of 

 Shorthorn milk, and 19*09 lb. or a little under 2 gallons of Jersey 

 milk were required to produce i lb. of butter. At the above 

 price the value of the butter contents of the Shorthorn milk 

 produced over the whole period is a little under 4^d. per gallon, 

 plus id. for the buttermilk, or 54d. per gallon in all, while the 

 Jersey milk is worth 6^d. plus id. for buttermilk, or something: 

 over 7d. a gallon in all. As a matter of fact, we had a private 

 connection for the sale of the butter at Bickenhall at a uniform 

 price of is. 3d. per lb. On this basis the value of the average 

 milk of the Shorthorns and Jerseys was 5|d. and just under 8d. 

 per gallon respectively (not including the value of the separated 

 milk;. There is little doubt that where a Jersey herd is kept^ 

 or even where half the milk manipulated is, as at Bickenhall^ 

 from Jersey cattle, a better price can be obtained from private 

 customers for the butter. 



From observations of the mixed milks of Jersey and Short- 

 horn cattle made later, it was found that a ratio of 22 was 

 obtained where the milks were mixed in equal proportions ; that 

 is to say, 2^ gallons of mixed milk sufficed to produce i lb. of 

 butter. The price per gallon actually realized for milk mixed
