Abstract: This study aimed to investigate the quality differences of eggs from caged partridges at different ages （300 d，500 d，and 800 d）to provide a scientific basis for partridge egg selection and breeding management. By measuring parameters such as egg weight，eggshell weight，egg shape index，eggshell strength，eggshell thickness， Haugh unit， yolk weight， yolk ratio， and albumen height， and performing correlation analysis， the study systematically assessed the changes in egg quality with age. The results showed that：（1）Egg weight and eggshell thickness significantly increased with age（P<0.05），whereas eggshell weight，eggshell strength，and yolk ratio first increased and then decreased，peaking at 500 d；（2）The Haugh Unit of eggs at 300 d was the highest（83.68 HU）；（3） The egg shape index was significantly negatively correlated with eggshell strength（P<0.05），and the eggshell thickness of eggs at 800 d（0.31 mm）was significantly greater than that of other ages. The study concluded that the eggs from partridges at 500 d had the best comprehensive quality，and it is recommended that in breeding production，high⁃ quality eggs be selected based on egg quality indicators.

摘要： 该研究旨在探究不同日龄（300 d、500 d、800 d）笼养鹧鸪蛋品质差异，为鹧鸪种蛋选 育和养殖管理提供科学依据。通过测定蛋重、蛋壳重、蛋形指数、蛋壳强度、蛋壳厚度、蛋白高 度、哈氏单位、蛋黄重、蛋黄比率等指标，结合相关性分析，评估鹧鸪蛋品质与鹧鸪日龄的相关 关系。结果显示：（1）蛋重、蛋壳厚度随日龄增长而显著增加（P<0.05），蛋壳重、蛋壳强度及蛋 黄比率呈先增后降趋势，500 d达峰值；（2）300 d蛋哈氏单位最高（83.68 HU）；（3）蛋形指数与蛋 壳强度呈显著负相关（P<0.05），800 d蛋壳厚度（0.31 mm）显著大于其他日龄。研究表明，500 d 鹧鸪蛋综合品质最佳，建议养殖生产中依据蛋品质指标精细化筛选种蛋。
