摘 要:在现代蛋鸡养殖行业中,规模化、集约化养殖是产业发展的主流方向,然而,蛋鸡产蛋性能受品种、日粮营养、环境、疫病防治等多方面因素的制约。随着国民生活水平的日益提高和健康意识增强,人们对鸡蛋需求量和品质的要求也越来越高,如何提高蛋鸡生产性能、增大经济效益、绿色发展产业已为新的关注热点。本文简述影响蛋鸡产蛋性能的因素,并总结应对措施,为后续研究提供理论参考。In the modern layer breeding industry,large-scale and intensive breeding is the mainstream direction of industrial development.However,the egg performance of laying hens is restricted by many factors,such as breed,dietary nutrition,environment,disease control and so on.With the development of living standards and increasing of health awareness,the demands of people on egg quantity and quality also increased.How to improve the production performance of laying hens,increase economic benefits and develop green industry has become a new focus.This paper briefly described the factors affecting egg performance of laying hens,and summarized the countermeasures,so as to provide theoretical reference for follow-up research.
