ABSTRACT:
An upwardly opening cup is provided including a lower inlet for upwardly directing spray jets of fluid thereinto and open and contoured at its upper end to fittingly accommodate not only a depending teat but also the portion of the udder immediately surrounding the selected teat. The interior of the cup includes radially inwardly projecting bristle-type blades for effecting a scrubbing action on the exterior of an associated teat in response to spray jets of liquid being upwardly directed onto the blades and the associated teat from the cup lower inlet, and the upper axial end of the cup includes a circumferentially extending zone of upwardly projecting flexible blades for contacting the udder area immediately surrounding the associated teat and tactilly stimulating the udder to facilitate quick and complete milk "let-down". The flexible blades carried by the upper circumferential zone of the cup are also caused to oscillate back and forth, laterally, in response to spray jets of liquid being discharged into the cup from the lower end thereof with the effect that the udder is tactilly stimulated in substantially the same as that accomplished naturally by the tongue of a nursing calf.
