A milking system includes a milk storage tank, a common milk line connected to the tank, at least two milking stations connected to the milk line, a milk constituent analyzing unit connected to the milk line and analyzing the milk provided from each of the stations through the milk line, with respect to a specific milk constituent, and a computer operatively connected to the analyzing unit. The computer stores milk quality information of the extracted milk and animal identity data of each of the specifically identified animals. Each station automatically identifies a specific animal, extracts milk from the animal, and transfers the milk through the common milk line to the milk storage tank. The stations, the computer, and the analyzing unit are operatively connected to allow a result of the milk analysis to be associated with the animal(s) identity specifically identified at each station from which the milk was extracted.
