Device for automatically feeding calves with a mixing container for mixing a liquid food product, a teat, a connection line, which connects the mixing container with the teat, a branch line, which branches off from the connection line at a branch point and connects the connection line with a pump and a controller for controlling the pump, where a sensor is arranged on the teat, which is connected with the controller and is designed to detect a movement and/or deformation of the teat, and the controller is designed to control the pump during detection of a movement and/or deformation of the teat such that liquid food product is delivered out of the branch line towards the branch point until liquid food product exits the teat.
