Abstract: The present invention relates to a liquid feed supply method of a feeder for pigs, wherein feed is manually supplied to a feeder plate located on the floor through a feed outlet on the lower side of a feed supply part of a hopper case accommodating the feed, and a water supply part separate from the hopper case is installed above the feeder plate and automatically supplies water, and thus a liquid feed comprising a mixture of the feed and water is supplied to pigs. In the present invention, when the height, from the floor surface, of the liquid feed stored in the feeder plate falls below a certain liquid level, water is automatically supplied for a predetermined period of time. Even if pigs are hungry and touch the feed outlet so that the feed comes out of the feed outlet, the water and feed stored in the feeder plate automatically mix to form the liquid feed, and water is not supplied until the liquid level of the stored liquid feed falls below a certain liquid level as the pigs continue to consume the liquid feed. Thus, the pigs have no choice but to finish the liquid-state feed that has already come out. Therefore, the feed cannot linger for a long time, and thus does not rot. When the liquid level of the liquid feed falls below the certain liquid level, a sensor senses the same and fresh water is supplied. The pigs can make fresh feed come out by touching the feed outlet and eat the liquefied feed, and can repeatedly touch the feed outlet to consume a large amount of fresh liquid feed. Thus, the pigs can maintain a good state of nutrition, and there is little loss of the liquid feed. Therefore, the present invention has the significant effect of being economical and providing a liquid feed supply device that is not prone to failure.
