HOW INDIVIDUAL SELECTION IS MADE

The organizations are cooperative in nature, but receive 

 a subsidy of about $ 60 per year from the government. The 

 organization is formed by the farmers of a neighborhood 

 owning from 300 to 1000 cows. A man is employed, usually 

 a student from an agricultural school, to do the testing. The 

 tester, or Control Assistant, as he is called, is also expected 

 to be able to advise the farmers regarding the feeding and 

 breeding of the dairy cattle. Each herd is visited in turn, the 

 frequency depending upon the number; the milk is weighed 

 for one day, the fat content determined by the Gerber 

 method, and a record of the feed consumed by each animal 

 is taken. All records are kept for the owner by the tester. 



The Danish system of expressing cost of production in feed 

 units is followed, and the records show the amount of milk 

 and fat produced by each cow, the amount of feed required, 

 and the results per 100 feed units. 



The following data illustrate the remarkable results that 

 have been obtained in certain herds.
