Electronic scales and Ethernet technology were used in the real-time data acquisition of Pigs' food intake and body weight to realize precision breeding of pigs. The control system was designed using programmable control technology to monitor environmental parameters and manage the daily information of the pig farm. The experiment results show that the each pig identity can be accurately identified, and the intake data and weight data can be gained accurately and timely, the control scope of the environmental parameter can meet the design requirements. The basic information of pigs can be put into the database correctly, and precision breeding and management of the commercial pigs can also be realized by making statistic analysis to the database. It made a successful exploration in precision breeding.
