Abstract: A teatcup includes a sleeve, a teacup liner provided in the sleeve, and a milk receptacle including a milk space. An inlet channel extends between an inner space of the teatcup liner and the milk space for conveying milk from a teat into the milk space. An outlet channel extends from the milk space and is connectable to a milk conduit for conveying the milk in a milk flow from the milk space. A gas supply channel conveys a gas into the milk space for promoting the milk flow. The gas supply channel has an inlet communicating with a gas source, and an outlet into the milk space. The milk space is partly delimited by a side wall. The gas supply channel extends within the side wall and along a surface of the side wall.
