摘 要
种鹅繁殖期的光照管理是影响其产蛋率的重要因素之一，但现有研究对不同光照方案的具体作用机制尚缺乏系统探讨。本研究旨在通过科学设计的实验方案，分析光照时长、强度及波长对种鹅产蛋率的影响，为优化养殖管理提供理论依据。研究选取300只健康成年种鹅，随机分为5组，在相同饲养条件下分别施加不同的光照处理，包括自然光照、延长光照时间、增加光照强度、改变光谱波长以及对照组。经过为期12周的监测与数据分析，结果表明，适度延长光照时间（每日14小时）和调整光谱波长（接近自然光的全光谱光源）可显著提高种鹅产蛋率，而单纯增加光照强度并未产生明显效果。此外，过长的光照时间可能导致种鹅应激反应，反而降低产蛋性能。本研究创新性地引入光谱波长变量，并结合行为学观察，揭示了光照条件对种鹅生理节律和生殖激素分泌的调控机制，为精准化光照管理提供了新思路。研究结果对提升种鹅生产效益具有重要实践意义。

INFLUENCE OF LIGHT MANAGEMENT ON EGG PRODUCTION RATE DURING THE BREEDING SEASON OF GEESE
ABSTRACT
Light management during the breeding period is one of the critical factors affecting the egg-laying rate of geese, yet existing studies lack a systematic exploration of the specific mechanisms underlying different lighting regimens. This study aims to analyze the effects of photoperiod, light intensity, and wavelength on the egg-laying performance of geese through a scientifically designed experimental protocol, providing theoretical support for optimizing farming practices. A total of 300 healthy adult geese were randomly divided into five groups and subjected to different lighting treatments under identical rearing conditions, including natural lighting, extended photoperiod, increased light intensity, altered spectral wavelength, and a control group. Over a 12-week monitoring and data analysis period, the results demonstrated that moderately extending the photoperiod (to 14 hours per day) and adjusting the spectral wavelength (using full-spectrum light sources mimicking natural light) significantly enhanced the egg-laying rate of geese. In contrast, increasing light intensity alone did not produce noticeable effects. Additionally, excessively long photoperiods were found to induce stress responses in geese, leading to a decline in egg-laying performance. This study innovatively incorporates the variable of spectral wavelength and integrates behavioral observations, elucidating the regulatory mechanisms by which lighting conditions influence the physiological rhythms and reproductive hormone secretion of geese. These findings offer new insights into precision-based light management strategies and hold significant practical implications for improving the productivity and economic benefits of goose breeding.
