A device for the controlled supply of animal feed includes a supply container, a feed trough with a side wall having an inlet, a conveying device with a drive unit connected between the supply container and the inlet of the feed trough, whereby the conveying device has an outlet opening that is coaxially arranged relative to the axis of the conveying device and the outlet opening is directly connected to the inlet of the feed trough. A control unit is connected to the drive unit for switching on and off the drive unit. A control flap is pivotably connected above the inlet and includes a control element that is connected to the control unit. The control flap activates the control unit for switching on and off the drive unit depending on the amount of animal feed present in the feed trough behind the control flap or due to activation by an animal to be fed. This device ensures that an animal to be fed only receives its allotted amount of animal feed because only after emptying the feed trough a new feed distribution is possible.
