The swine industry is the pillar industry of animal husbandry in China. With the development of national economy and the scale farming, the demand for engineering technology of swine facilities is increasing in China. In order to provide reference and support for the development of swine farming, the research and application of key facilities engineering technology in swine farming were summarized and analyzed. The research and development of pig houses, piglet breading facilities, feeders and manure disposal facilities were mainly analyzed. At present, the engineering technology system for swine facilities and equipment was established in China, which can meet the demand of swine farming in China, but there was still a certain gap compared with the engineering technology of swine facilities in developed countries in animal husbandry, the development of various links in swine facilities engineering was not balanced, and the technical level of mechanization, automation and intellectualization of the facilities engineering was low. The basic researching system of key facilities engineering technology was not perfect, the matching of swine facilities was poor, and the applicability and reliability of swine farming equipment was low. Establishing a perfect researching system for the engineering technology of swine facilities, and strengthening the integration and cooperation of breeding, feed, facilities, resources and environment, and then boosting the research and development of swine facilities and equipment suitable for the supporting applications in the North and South China, so as to realize the health/welfare, ecology, automation and intellectualization of the swine farming process, which would be the development trend of swine facilities engineering technology in China.
