| 摘 要： | 通过模拟常压低氧和高海拔增氧孵化试验，研究了氧气浓度对低地良种鸡蛋胚胎死亡率和孵化率的影响。死亡胚胎的分布用2阶段增长模型分析。模拟2900m海拔常压低氧孵化增加了胚胎后期死亡率，使孵化率降低到接近2900m海拔实际孵化率水平；2900m海拔全期增氧孵化可以有效降低前期和后期胚胎死亡率，大大提高孵化率；阶段增氧孵化也能不同程度提高孵化率，改变胚胎死亡分布，其中效果最好的为前期增氧组。结果说明低氧是影响2900m海拔鸡蛋孵化的最主要因素。

| Abstract: | Incubation experiments in simulated normobaric hypoxia condition and at high altitude with adding oxygen were conducted to explore influences of oxygen on embryonic mortality of chicken. The distributions of dead embryos were analyzed by a multiphasic model. Embryonic mortality during the later phase increased in incubation simulated 2 900 m altitude comparing with normobaric hypoxia, and the hatchability was closed to hypobaric hypoxia control. At 2 900 m altitude, incubation with adding oxygen during incubation reduced embryonic mortalities during early and later phase, and increased hatchability. Adding oxygen during early or middle or later phase would increase the hatchabilitis and change the distributions of dead embryos in different degrees, and the effect of early phase was the best of all. The results indicated the hypoxia was the important factor that influenced hatchability of chicken eggs at 2 900 m altitude. |
