A drinking spout for livestock, especially for pigs, is connected approximately horizontally at back height to the water line in the stall. The volume of water is regulated from outside by means of a screwdriver or key, using the screw 4. When this is done, the valve stem 3 with the steel rod 6 is pressed into the groove 7. Each rotation of the screwdriver changes the volume of water flowing through. Simple and inexpensive adjustability. <IMAGE>
