346 LIVE-STOCK RULES AND RECORDS 



a herd-book based upon individual merit, and designed as an aid to 

 improvement within the breed. Advanced registry is especially 

 adapted to the improvement of the dairy breeds of cattle. The registry 

 is made on the report of an official test as to milk yield and butter-fat, 

 conducted by an Experiment Station. 



The Advanced Registry system has had marked effect in discovering 

 and publishing the good animals, eliminating the poor animals, and 

 standardizing the performance. The four leading dairy breeds in 

 America Holstein, Jersey, Guernsey, and Ayrshire now have well- 

 authenticated records as a result of this system. 



As illustrating the nature of the test to warrant Advanced Registry, 

 the following set of general rules of the Holstein-Friesian Association 

 of America is inserted : 



1. The Station representative shall be present at the last regular 

 milking preceding the beginning of the test and shall satisfy himself 

 that the cow is milked dry at that time. He shall note the hour at 

 which this milking is made ; and the final milking of the test, whatever 

 its length, must be at exactly the same hour. 



2. He must be present at each and every milking during the test, 

 and satisfy himself that at the close of each milking the pail contains 

 nothing but the milk drawn from the cow under test. 



3. Under no circumstances can more cows than one undergoing test 

 be milked at the same time. The Station representative must in every 

 case be in position to observe the milker during the whole milking. 



4. Immediately after the milk is drawn at each milking, he will 

 take charge of the pail and contents, will weigh the same to pounds 

 and tenths on scales provided by his State Experiment Station, and 

 enter the exact weight of milk at once in his note-book. He will then 

 take a correct sample of the milk, sufficient for his own tests and for 

 the composite sample to be sent to the Station, in accordance with the 

 following directions-: 



5. As soon as the milk has been weighed it is to be thoroughly 

 mixed by pouring it from one pail to the other, or by means of a dipper ; 

 and a pint fruit jar is to be immediately filled about two-thirds full of 

 milk for the test samples. The Station representative takes charge of 

 and is personally responsible for this sample. It should be kept under 

 lock and key until tested. The test is proceeded with as soon as con- 

 venient, after the milk has cooled to ordinary room temperature.
