Abstract: With the improvement of porcine performance, porcine feed intake became one of the significant factors which limited performance. Porcine potential genetic performance and benefits were directly affected by feed intake, so special interest was generated among farmers and animal breeders. Porcine feed intake was influenced by environment, feed, health, genetic features and so on. In physiology, porcine feed intake mainly controlled by feeding center and satiety center of hypothalamus, and was accurately regulated by several regulatory genes which interacted with each other. This review was focused on the regulatory mechanism, influencing factors of feed intake and research progression of major genes.
