Abstract: Pig behaviors are the comprehensive responses to its living environment and feeding way. The normal behaviors of swine are seriously affected under intensive feeding condition. Here, we presented a review on feeding behaviors, discharge behaviors, social behaviors, maternal behaviors and abnormal behaviors of swine, and analyzed the application of these behaviors in feeding and management. The knowledge on pig behaviors rendered in this paper may provide some references for correct understanding of pig behaviors for employed persons in swine production and for scientific application of feeding and management measures, so as to improve the production performance of pig herds and the economic benefit of pig industry.
