The present invention relates to a milk conveyer device (100) for a milking arrangement. The milk conveyor device comprises a milk storage reservoir (101), at least one milking unit comprising a milking attachment for attaching to an animal to be milked, and a main milk conduit (103,105), coupled to the milking attachment and the milk storage reservoir (101), for conveying milk from the milking attachment to the storage reservoir (101). The milk conveyer device (100) further comprises an analysis element (129) for analysing at least one selected characteristic of an analysis milk sample generated from a milk analysis quantity, a plurality of milk sample units, each of which comprises a sample element (107,109) for extracting sample milk quantities from the milk of the main milk conduit (103,105), a plurality of sample reservoirs (115,117) coupled to each of the sample elements (107,109) for collecting the sample milk quantities to generate the milk analysis quantity, and a plurality of analysis conduits (123,125), coupled to each of the sample reservoirs (115,117) for conveying the milk analysis quantity from the sample reservoirs to the analysis element (129). A selector unit (127,300) is coupled to the plurality of analysis conduits (123,125) of the milk sample units. The selector unit (127,300) is operable to couple milk from one of the plurality of analysis conduits (123,125) to the analysis element (129) at a time.
