摘　　要：The reproductive performance of female chickens is critical for determining the efficiency of production and productivity and thus profitability.Studies have shown that the reproductive performance of female chickens is mainly regulated by the feed,hormones,genes,and light conditions.Herein,we review the major factors regulating female chicken reproductive performance and assess the reproductive organs and their functions.In the current review,we highlight how the interconnections of hormones,candidate genes,and photo-stimulation regulate female chicken reproductive hormones and thus regulate the reproductive organ performance.In this regard,the roles of main hormones[gonadotropinreleasing hormone(GnRH)and genes(GnRH-Ⅰ)]in regulating sexual maturation and ovarian development and maintenance by influencing the survival and function of follicular granulosa cells were also reviewed.In addition,the current review also highlights how feeding female chickens with diets and artificial light-emitting diodes(LEDs)support the effective functioning of their reproductive capacity through the stimulation of sexual maturity at an appropriate age and regeneration of aged reproductive organs.
