ABSTRACT
The bulk of the market milk handled in our cities is bought by the quart, gallon, can or hundred weight, a certain base price being paid for milk containing a certain per cent of fat plus or minus a butter fat premium. The question of how to accurately determine the average per cent of fat in the milk of their patrons month by month and keep everybody satisfied is a problem milk dealers have been facing for some time.
Obviously the most accurate method would be to sample and test each patron's milk daily. This, however, would necessitate so much work as to make it impractical.
Some methods in use involve the taking of composite samples and testing them usually, every two weeks. Sometimes aliquot portions of each day's milk are taken using the sampling tube, and sometimes the same amount is taken out of each delivery by using a small dipper.
