The present invention provides a TMR intelligent feeding system and feeding method based on a 5G network. The intelligent feeding system comprises a feeding trough, a feed moving device, a feed spreading device, a feed supporting device, a recovery device, a feeding device, an information collection system, a feed eating cooling system, a feed eating reminder system, a metal detection system and aforeign body recognition system. The feed moving device, feed spreading device, recycling device, feeding device, information collection system, feed eating cooling system, feed eating reminder system, metal detection system and foreign body recognition system realize signal transmission through the 5G network and a remote control center. Feeding methods comprise ration preparation, loading, unloading, spreading, receiving and weighing. A traditional manual TMR distribution and feeding scheme is overturned, an unmanned feeding process is realized, structure of a cow house is optimized, freshness of TMR is ensured, comfort of the cow house is maximized, and a play of an advantage of genetic genetics of an ultra-high yield of 15 tons or more is provided with hardware and software guaranteein a TMR feeding link.
