The invention relates to the technical field of breeding feed feeding, in particular to a feed circulation and transfer system which is used for reducing feed residues in a conveying and transfer line in the automatic feeding process and comprises a feed box, a circulation pipeline and a circulation rigging, a discharge port is formed in the circulation pipeline, the feed box comprises a feed box inlet and a feed box outlet, and the feed box inlet is communicated with the circulation pipeline. The circulation pipeline comprises a plurality of corner devices, and the corner devices are arranged at the corners of the circulation pipeline; the circulating rigging is in a closed loop shape, a plurality of shifting pieces are arranged on the circulating rigging, and the circulating pipeline and the material box are connected to the closed loop path of the circulating rigging in series. At least one corner device is provided with a corner driving mechanism, and the corner driving mechanism comprises a corner driving wheel and a corner driving motor. The device has the advantages that feed waste is reduced, feed cleanness is guaranteed, a long conveying path can be self-cleaned to a certain degree, and the service life is long.
