Abstract: At present, problems such as excessive feeding density, feed waste, low production efficiency and environmental pollution are common in intensive and large-scale laying hen farms in China. The precision feeding technology of commercial laying hens can systematically monitor the organism condition of laying hens at different stages and develop personalized feeding programs based on the characteristics of nutritional requirements and changes in feed intake of laying hens, which can improve feed conversion and production performance, increase economic efficiency, reduce environmental problems such as nitrogen and phosphorus emissions, and promote the sustainable development of laying hen farming. In this paper, the application points and development trends of precision feeding technology for laying hens were reviewed in terms of nutritional control measures, feeding management and environmental control, and immunization and hygiene in different stages of laying hens, with the aim of improving the level of commercial laying hens and improving breeding efficiency.

Key words: laying hens, nutritional regulation, accurate feeding, environmental control
