A feed conveying system is provided and the feed conveying system includes a conveyor trough, a conveyor chain, a driving gear, at least one steering gear and a power unit. The conveyor trough includes a trough bottom and at least one steering region. The conveyor chain is disposed in the conveyor trough and the conveyor chain includes a plurality of first loops, a plurality of second loops and a plurality of transporting structures. One of the second loops is coupled between two of the first loops. The transporting structures are respectively connected to the second loops, and disposed between the second loops and the trough bottom. The driving gear is operated to drive the conveyor chain. The steering gear is disposed in the steering region, and stretches a plurality of L-shape steering structures, wherein breaches of the L-shape steering structures face the trough bottom. The power unit is operated to drive the driving gear. The conveyor chain is disposed around the driving gear and the steering gear.一種飼料傳送系統,包含輸送槽、輸送鏈條、傳動齒輪、至少一轉向齒輪及動力單元。輸送槽包含槽底及至少一轉向部。輸送鏈條設於輸送槽中,且包含複數個第一環狀物、複數個第二環狀物及複數個傳送結構。其中,第二環狀物之一者扣合於第一環狀物之兩者之間。傳送結構分別連接第二環狀物,且設置於第二環狀物與槽底之間。傳動齒輪係操作以連動輸送鏈條。轉向齒輪係設於轉向部,且放射線地突伸出複數個L型轉向結構,其中L型轉向結構之缺口朝向槽底。動力單元係操作以連動傳動齒輪。輸送鏈條係圍繞傳動齒輪及轉向齒輪。100‧‧‧飼料傳送系統102‧‧‧局部110‧‧‧輸送槽112‧‧‧槽底114‧‧‧轉向部120‧‧‧輸送鏈條122‧‧‧第一環狀物124‧‧‧第二環狀物126‧‧‧傳送結構130‧‧‧傳動齒輪132a‧‧‧第一齒132a’‧‧‧止擋部134a‧‧‧第二齒136‧‧‧主體140‧‧‧轉向齒輪142‧‧‧旋轉軸心144‧‧‧L型轉向結構160‧‧‧飼料源162‧‧‧輸送管164‧‧‧飼料槽170‧‧‧飼料放置槽180‧‧‧飼養區域
