This study analyzes 324 captive giant panda breeding events (1998-2023) to unravel maternal and gestational drivers of cub survival and health-the largest dataset of its kind to date. Key variables included gestational duration, maternal age, interbirth interval, number of cubs per breeding event, cub birth weight, and neonatal mortality. Maternal age (5-7 years, ≥20 years) and interbirth intervals ≤1 year were linked to increased neonatal mortality, whereas intermediate gestational durations (110-127 days) and longer interbirth intervals (≥4 years) correlated with higher cub survival ratios. Although no direct relationship was found between gestational duration and birth weight, singleton cubs exhibited significantly higher weights than twins. By quantifying these relationships, we propose actionable strategies to enhance reproductive efficiency in managed populations, such as adjusting breeding schedules and maternal health monitoring.
本研究分析了324次圈养大熊猫繁殖事件（1998年至2023年），以揭示幼崽生存和健康的母体及孕期驱动因素——这是迄今为止同类研究中规模最大的数据集。关键变量包括孕期时长、母体年龄、产仔间隔、每次繁殖事件的幼崽数量、幼崽出生体重和新生儿死亡率。母体年龄（5至7岁、≥20岁）和产仔间隔≤1年与新生儿死亡率增加有关，而中等孕期时长（110至127天）和较长产仔间隔（≥4年）与较高的幼崽存活率相关。虽然未发现孕期时长与出生体重之间存在直接关系，但单胎幼崽的体重明显高于双胎。通过量化这些关系，我们提出了可采取的策略，以提高圈养种群的繁殖效率，如调整繁殖计划和监测母体健康状况。
