dry at the regular milking period. He then carefully weighs the 

 milk and makes a butter- fat test at each milking, the last milk- 

 ing closing exactly 48 hours after the close of the preliminary 

 milking. The average percentage of fat found during these 

 two days is used as the average for the month. From the milk 

 record sent in by the breeder and the report by the supervisor, 

 the officers of the association figure the amount of fat produced 

 during the month. This method is not adopted by all the breed 

 associations for Advanced Register. The breeds included are 

 Holstein-Friesian, Jersey, Guernseys, Ayrshire, and Brown

The yearly requirements of the American Guernsey Cattle

 is taken at the beginning of the test and not necessarily at the 

 time of last calving or aborting. 



The Ayrshire Breeders' Association requires that a cow 

 which is two years old or under at calving shall produce 6,ooo
