The present invention relates to a water supply apparatus for a poultry farm, including: a support where a vertical supporting shaft is formed on an upper surface with a line connected to the upper end, and a step is formed in the middle of the supporting shaft; a semi-spherical scupper where a water supply port is formed at a lower end outer circumferential edge, a water supply chamber is provided at the upper end by a housing with a water supply hole being formed at a lower end of the housing; a supporting pipe placed on the step of the supporting shaft with a locking step formed at the upper end thereof, where a spring is disposed on the upper side and a screw portion is formed in the outer surface; a rubber ring holder screw-assembled such that lifting and lowering are performed in the screw portion of the supporting pipe, where a blade portion is formed on the outside with a rubber ring accommodated on the upper surface of the blade portion; a cap assembled by a cap holder on the upper side of the housing, with a nozzle being formed at one end of the cap and connected from the outside to the inside; and a spring holder screw-assembled at the upper end of the cap and supporting the spring. The nozzle brought into contact with the rubber ring is allowed to have a stable close contact, and thus water blocking can be performed with accuracy, which results in more hygienic environments and water waste reduction. In addition, the rubber ring holder is lifted and lowered with respect to the supporting pipe, and thus water supply amount control can be performed at will and water supply can be adequate in accordance with the state of poultry individuals.;COPYRIGHT KIPO 2017
