This paper analyzed live pig production, consumption and price, and proposed the monitor system and the early warning mechanism. It is indicated that the study has a theoretical and practical significance in this area in China. In the view of the unusual fluctuation in the current live pig and its product prices, we carried out more works in live pig risk factors, fluctuation, detection methods, model building, as well as R & D relevant circumstances. In order to facilitate future studies in this field and to provide a useful exploration, we additionally proposed the implementation of the program of research and design at the last part of the paper.
