The present invention relates to a liquid feed supply method, and feed is supplied to a feeder plate located at the bottom through the lower outlet of the feed supply part of a hopper case containing feed, and a water supply part separate from the hopper case is placed on the upper part of the feeder plate. In the liquid feed supply method of supplying liquid feed mixed with feed and water to pigs, The water supply unit is installed in a water supply pipe 80 installed to receive water to be supplied to the feeder plate 30, and is installed in a part of the water supply pipe 80 to move while a little bit of feed in a liquid state remains. A solenoid valve that opens and closes so as to control whether or not water is moved according to a voltage signal from the controller, a sensor 110 that is spaced apart from the top of the feeder plate 30 to a certain height, and the sensor 110 detects it. It consists of a circuit part that generates a measured value actually needed through the measured voltage value and a control part that controls the solenoid valve through the measured value of the circuit part, and the control part controls whether or not the solenoid valve is opened or closed, In the present invention, water is resupplied while the liquefied feed remains on the floor, and the feed is mixed with water by touching the tube to come out of the outlet. Since it remains in a state, it does not interfere with eating mixed with water even if the feed continues to come out of the outlet, and the feed that has been liquefied continuously because water is resupplied again can be consumed seamlessly, allowing a remarkable effect of ingesting a large amount without interruption.
