Pig farming is an important part of China's animal husbandry industry, and the continuous growth of the farming scale has continuously increased the performance requirements of farming equipment. At present, China's pig farming industry is in the primary stage of intelligent animal husbandry, and automatic equipment has been widely used and intelligent equipment is being developed continuously. The automation equipment and technologies commonly used in the current pig breeding industry were analyzed, and the technical means in terms of pen, feeding, environmental control and manure treatment, the advantages and disadvantages of different equipment and the applicable scenarios for comparative analysis were introduced; the intelligent equipment and technologies in the new stage of pig breeding were elaborated based on the current development process, the intelligent perception, Internet of Things, cloud computing and other technologies on the existing intelligent feeding and environmental control equipment were combined, and the application of artificial intelligence technology in the equipment of pig breeding was expounded, including the application of machine vision and speech processing technology in the intelligent detection system of pig breeding, and the development of robotics in replacing manual labor for breeding operations. Finally, the current research focus on the development of pig automation farming equipment was summarized, and the development trend of pig automation and intelligent equipment research was looked forward.
