Abstract: Supernormal fluctuations of pig prices increase the breeding risk of live pig and the earnings instability.Frequent fluctuations of pig price affected the rationality of decision-making of breeding subjects,and the irrationality of the decision-making of breeding subjects also caused obvious obstacle for the popularization of healthy breeding of live pigs.In order to break through the restrictions of price fluctuation of live pigs on the popularization of healthy breeding of pigs,the coordination between the central policy and local policy should be ensured,reasonable interest relationship between different subjects in the industry chain of live pig should be constructed,the expectations of breeding subjects should be adjusted,the popularization model and method should be changed according to the demands of breeding subjects.
