The cooling water supply system which is provided in the barn in order to raise domestic animal such as dairy cow is offered. The water supply stand which consists of the flame tube body and the barrel body and the ascent and descent body from the upper surface of the water tank facilities is done inside, the opening and closing valve is provided on bottom of the ascent and descent body, the feed pipe, the waste pipe, the overflow tube and the heating heater which possess the intermittent valve, the water level inspection sensor, and the temperature inspection sensor are provided in the water tank. The water is drunk and be able to take in domestic animal such as dairy cow with the ascent and descent body which has possessed the water of place fixed quantity, the opening and closing valve which is provided in the ascent and descent body as the role which always maintains the water level of ascent and descent internal uniformly is done, cutting off the fact that the foreign material flows inside the water tank, prevents the corruption of the water. In addition as for the water supply stand of water tank top being opened by the smallest size which can drink the water, it is possible, is superior in the winter insulative effect, to minimize thermal loss, it is always clean, at the same time it can offer the water of proper temperature.< Selective figure >Figure 1乳牛などの家畜を飼うための畜舎に設けられる給水装置を提供する。内筒体と外筒体及び昇降体からなる給水台を水タンクの上部面から内側に挿設し、昇降体の底部には開閉弁を設け、水タンクには断続弁を有する給水管、排水管、オーバーフロー管、加熱ヒーター、水位検知センサー、及び温度検知センサーを設ける。所定量の水を有している昇降体によって乳牛などの家畜は水を飲んで摂取でき、昇降体に設けられた開閉弁は昇降体内の水位を常に一定に維持する役割をすると共に、水タンクの内部に異物が流入することを遮断して水の腐敗を防止する。また水タンク上部の給水台は水を飲むことができる最小サイズに開放されていて、熱損失を最小化することができ、冬季保温効果に優れ、常に清潔で、且つ適正な温度の水を提供できる。【選択図】図1
