摘要: 随着猪生产性能的提高,猪的采食量成为限制生产性能的主要因素之一,猪的采食量直接影响遗传潜力的发挥和生产效益,因此,受到养猪者和研究人员的重视。影响猪采食量的因素很多,包括环境、饲料、健康、遗传特性等,从生理上讲,它主要由下丘脑的摄食中枢和饱中枢控制,下丘脑通过各种调节因子对食欲进行着精细的调节,而且这些调控因子之间存在着交互作用。作者主要对猪群采食量调节机制、影响猪采食量的因素及调控猪采食量的基因研究进展做一综述。

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.
