Abstract: Large scale pig industry has taken rapid progress at present in China, but the breeding facilities and technical measures are still more backward than the developed country. In order to improve the benefits of pig industry, a kind of digital breeding platform was constructed by using the advanced technical measures. The whole platform including the auto-feed conveyor and precision feeding system, intelligent regulation system of pig house environment, management system of pig information, visualization monitoring system of the pig house and the network supervision system of the whole pig-breeding process were realized by taking advantage of several digitization technologies such as RFID (radio frequency identification), intelligent controlling and network transmission technologies. At the same time, its corresponding constructing methods of every subsystem were illustrated in details in this paper. As a demonstrating engineering in Science and technology Park of Inner Mongolia Autonomous Region, it will play a significant role in applying the digitization technologies into all pig houses and further developing the digitization pig industry.
