The present invention relates to a device for compressing, crushing and supplying feed. More specifically, the device comprises: a feed discharge unit formed such that a portion of a feed pipe for automatically supplying feed into a feedbox is opened to discharge feed to be transferred a feed inlet unit formed such that another portion of the feed pipe located in the feed transfer direction than the feed discharge unit is opened to introduce crushed feed which has been compressed thereinto a compression crushing means for crushing the introduced feed by compression and supplying the introduced feed to the feed inlet unit and a circulation means for selectively supplying the feed discharged through the feed discharge unit to the compression crushing means. The feed discharged through the feed discharge unit is introduced into the compression crushing means and is compressed and crushed, and is fed back to the feed pipe through the feed inlet unit by the circulation means. According to the present invention, the device is installed to be easily connected to a feed pipe installed in a pen. As the feed is compressed and crushed into a particle size by which livestock can easily digest and is supplied to the feed pipe to improve digestibility of the livestock, the cost can be saved by reducing the amount of feed discharged and discarded without being digested as compared to the prior art and reducing the amount of feed used to satisfy daily intake. Moreover, even if the device for compressing, crushing and supplying feed fails, the feed can be continuously supplied through the feed pipe, thereby improving the efficiency of supplying feed.COPYRIGHT KIPO 2017본 발명은 사료 압착분쇄 공급장치에 관한 것으로, 더욱 상세하게는 사료를 먹이통으로 자동 공급하기 위한 사료파이프의 일부분이 개방되도록 형성되어 이송되는 사료가 배출되기 위한 사료배출부, 상기 사료배출부보다 사료이송방향에 위치된 상기 사료파이프의 다른 부분이 개방되도록 형성되어 압착시켜 분쇄된 사료가 유입되기 위한 사료유입부, 유입되는 사료를 압착에 의해 분쇄하여 상기 사료유입부로 공급하는 압착분쇄수단, 및 상기 사료배출부를 통해 배출되는 사료를 상기 압착분쇄수단으로 선택적으로 공급시키기 위한 순환수단,을 포함하고, 상기 순환수단에 의해 상기 사료배출부를 통해 배출되
