In order to provide a feed mixture, a feed mixer is proposed which has a container (1). The container (1) has a bottom (8) and a wall (10) which is connected to the bottom (8) and delimits a filling opening (9), the area of which is greater than the area of the bottom (8). A rotatable auger (2) is provided which can be rotated about an axis (X), the axis running substantially perpendicularly with respect to the bottom (8). The feed mixer has a pivoting device which is intended and suitable for pivoting the container (1) during a mixing operation, in particular after a predefined time period or after a predefined number of revolutions of the at least one auger (2).
