An automatic feeding control system for large-enclosure cultivation comprises a weighing sensor, a quantitative distribution controller, an electronic ear tag recognizer, a control cabinet, a distribution screw scale and an electric push rod. The quantitative distribution controller, a rotary knob switch and a plurality of button switches are arranged on a cabinet door of the control cabinet. A switch power supply, a circuit breaker, an RTU controller, an electromagnetic relay and a UK wiring terminal strip are arranged in a cabinet body. An external power supply is connected with a security device through the circuit breaker. The security device is electrically connected with the switch power supply which is connected with the rotary knob switch. The hand-operated output end of the rotary knob switch is connected with all the button switches. The automatic output end of the rotary knob switch is connected with the RTU controller. All the button switches and the RTU controller are connected with the electromagnetic relay. The output contact of the electromagnetic relay is connected with the UK wiring terminal strip. The UK wiring terminal strip is connected with the distribution screw scale and the electric push rod respectively. By switching the rotary knob switch, the system can conduct distribution control at a hand-operated state and an automatic state; according to electronic ear tag data, different types of feed are distributed to livestock.
