Abstract
Methods and apparatus enabling a diagnostic test to be carried out on milk flowing in a milk line from an animal being milked, without interrupting the milking process, in which a portion of the milk is diverted through a by-pass in which an extracting means (14) in the form of a vacuum-operable pump and timer acts to separate from the milk flowing in the by-pass a milk sample and to deliver said sample through an associated sampling valve (16) to a testing device (18).
