224 AYRSHIRE MILK. 



milk takes a somewhat longer time to churn. The 

 effect of the acids developed in the milk by keeping 

 also appears to affect the churning qualities of the 

 milk to a less degree. Therefore, although the 

 Jersey milk may be skimmed, certainly not later 

 than when the milk commences to thicken or " lob- 

 ber" at the bottom of the pan, the Ayrshire milk 

 should pass considerably beyond this point, and 

 develop somewhat more acidity, before the cream is 

 removed.

In the new-milk churning, when the globules of 

 the two breeds were about of a size, the Jersey milk 

 churned much the quicker, probably on account of 

 the thinness of the enveloping membrane of the 

 globules. In the Jersey cream we also have a sim- 

 ilar result, although the globule is smaller than in 

 the Ayrshire cream, with which it is compared. 



The butter from the Ayrshire cow is of good tex- 

 ture ; is yellow, often a deep yellow, but, as far as 

 I have observed, not possessing the peculiar orange 

 tinge of the Jersey. 



The typical cheese family of Ayrshires furnishes a 

 milk of much smaller globules and more numerous 

 granules than the butter type of Ayrshire milk. The 

 milk throws up a small percentage of cream, and is
