PURPOSE: An automatic cold and hot water supply for a livestock shed is provided, which can supply cold water to domestic animals in summer. CONSTITUTION: An automatic cold and hot water supply for a livestock shed comprises a drinking water supply drain(2) for a livestock shed; and a pump(1) and a water temperature sensor which are installed in the side of the drain. An exhaust line is a little bit highly installed in the top end portion of automatic cold and hot water supply for the livestock shed. Drinking water of the automatic cold and hot water supply is ejected through the exhaust line by operation of the pump when water temperature is higher than the set temperature. The operation of the pump is automatically stopped when the cold water is sensed by the water temperature sensor and the automatic cold and hot water supply is filled with water.
