According to the present invention, a feed supply apparatus is disclosed. The disclosed feed supply apparatus includes a feed storage container for providing the feed to a feed vessel by continuously discharging the feed, a drinking water storage container for providing the water by continuously discharging the water, and a gap adjustment mean for adjusting the time gap between the feed and drinking water supplies as a preset time gap, wherein the gap adjustment mean includes a cover for closing and covering a feed outlet, a drinking water tray for receiving and storing the drinking water discharged from a drinking water outlet, a connecting structure connecting the cover and the drinking water tray, and a support structure rotatably supporting the cover, the drinking water tray and the connecting structure by being disposed between the cover and the drinking water tray and pivot-hinged to the connecting structure. The cover and the drinking water tray are mounted to be rotated between a first rotation position where the cover covers the feed outlet and the drinking water tray receives drinking water discharged from the drinking water outlet according to the amount of the drinking water stored in the tray, and a second rotation position where the cover does not cover the feed outlet and the drinking water tray spills the stored drinking water when the tray is tilted at a predetermined angle. The feed supply apparatus is configured to use Clepsydra principle, is eco-friendly for not using electricity and may provide user convenience since it can be used even where an electricity supply facility is not located.COPYRIGHT KIPO 2015사료공급장치가 개시된다. 개시된 사료공급장치는, 사료를 연속적으로 배출하여 사료 용기에 공급하도록 된 사료 저장통과, 식수를 연속적으로 배출하여 식수 용기에 공급하도록 된 식수 저장통과, 사료 및 식수의 공급을 소정시간 간격으로 조절하기 위한 간격조절수단을 포함하고, 간격조절수단은, 사료 배출구를 커버하여 폐쇄하도록 된 개폐커버와, 식수 배출구에서 배출되는 식수를 받아 저장하도록 된 식수받이와, 개폐커버와 식수받이를 연결하는 연결대 및, 개폐커버와 식수받이 사이 배치되고 연결대와 힌지축 결합하여 개폐커버와 식수받이 및 연결대를 회동 가능하게 지지하는 지지대를 포함하되, 개폐커버와 식수받이는, 식수받이에 저장된
