摘　　要：饲料中含有多种营养物质用于畜禽生长发育和繁殖,其中主要是能量和蛋白质,而其他微量元素和维生素等需要量相对较少。日粮能量水平是决定家禽生产性能和饲料成本的重要营养素。下丘脑-垂体-性腺轴对性成熟和繁殖行为具有重要调节作用。文章综述日粮能量水平对蛋鸡生产性能、繁殖性能和卵泡发育的影响,以及HPG轴与能量平衡之间关系,为蛋鸡产蛋和繁殖能量调控机制奠定理论基础和调控依据。The feed contains a variety of nutrients for the growth, development and reproduction of livestock and poultry, mainly energy and protein, while other trace elements and vitamins are relatively small. Dietary energy level is an important nutrient that determines production performance and feed cost of poultry. The hypothalamic-pituitary-gonad axis plays an important role in regulating sexual maturation and reproductive behavior. This paper reviewed the effects of dietary energy levels on production performance, reproductive performance and follicular development of laying hens, as well as the relationship between HPG axis and energy balance, so as to lay a theoretical foundation and regulatory basis for the energy regulation mechanism underlying laying and reproduction.
