摘　　要：产蛋率是评价蛋鸡生产性能的重要指标,是衡量蛋鸡养殖企业饲养效率和盈利能力的重要因素之一。老龄化是导致蛋鸡产蛋后期产蛋率下降的主要因素。特别是近年来,商品蛋鸡的产蛋周期大大延长,蛋鸡老龄化程度更高,导致产蛋后期面临的产蛋率下降问题更为严峻。文章对鸡蛋的形成过程及引起蛋鸡产蛋后期产蛋率下降的原因进行了概述,并对提高产蛋后期产蛋率的营养调控措施进行了总结和展望。Laying rate is an important index to evaluate the production performance of aged laying hens.It is also one of the most important factors to measure the feeding efficiency and profitability of laying hens breeding industry.The aging is the major factor leading to the decrease of laying rate in the late laying period.Especially in recent years,the laying cycle of commercial laying hens has been greatly prolonged,and the aging situation of laying hens is serious,which leads to a more severe problem of the decline of laying rate in the late laying period.In this paper,the process of egg formation and the reasons for the decrease of laying rate in the late laying period were summarized,and the nutritional regulation measures to improve the laying rate in the late laying period were also summarized and prospected.
