The invention discloses an intelligent live pig feed breeding device. The device comprises a storage box, a feeding cylinder, discharging cylinders, electromagnetic on-off valves, a rack, a mounting base, a controller and a containing part, the feeding cylinder is fixed to the front end of the storage box, and the vertical discharging cylinders are fixed to the left portion and the right portion of the bottom end of the storage box correspondingly; and the feeding cylinder and the discharging cylinders communicate with an inner cavity of the storage box, and the two discharging cylinders are each provided with one vertical electromagnetic on-off valve. According to the intelligent live pig feed breeding device, no extra breeding site is occupied within non-feeding time, so that more activity space is vacated for live pigs, the pollution of the device is reduced while the normal growth of the live pigs is ensured, and the fixed-point, fixed-time and quantitative feeding of the live pigscan be realized by presetting the weight of the feed fed each time and the feeding time point, therefore, normal feeding is guaranteed, meanwhile, extra waste of the feed is avoided, and environmental protection and high efficiency are achieved.
