  • milk remains in the form of a drop or film on the gland opening, which is removed by the calf with the tongue in suckler cows. Such a situation is not present in dairy cows that are milked by machine. If this drop or film is not removed, the milk forms a nodding medium for the multiplication of bacteria originating from the environment, which thus have an opportunity to prevent the Penetrate the duct and trigger an infection of the gland.

It is also possible that different lines are available for different milk qualities in order to divert milk of particularly high quality or with a particularly high fat content into a special tank.

As a result, the teat cup could migrate upwards during the milking process and press against the Mariethbergian vein ring, as a result of which, among other things, the milking readiness of the animal may drop. By drying the teat before milking, the lubricating film is removed.

For example, when spraying from below, the teat may be sprayed at a lower pressure than when sprayed from the side. The lower pressure during spraying produces a lower exit velocity.

Abstract

L'invention concerne un gobelet trayeur (30) et un procédé de mise en contact d'un fluide et d'une mamelle. Ledit gobelet trayeur (30) comporte un boîtier et un caoutchouc à mamelle (32) logé dans le boîtier (31), séparant un espace à mamelle et un espace à impulsions, et présentant une zone de tête (33), une zone de tige et une zone terminale communiquant avec un tuyau à lait. Ledit gobelet trayeur comporte également une vanne permettant de fermer de façon étanche une connexion fluidique entre l'espace à mamelle et un tuyau à lait. La zone de tête (33) présente au moins une zone de sortie (34) conçue de telle manière qu'un fluide quittant la zone de sortie (34), notamment un fluide désinfectant, est dirigé au moins partiellement vers l'intérieur de façon radiale.
