摘　　要：为贵州黄鸡种蛋的选择提供参考依据,在相同孵化条件下,利用贵州黄鸡13世代种鸡生产的种蛋进行了研究.结果表明：种蛋在整个孵化期都处于稳定失重过程,蛋重越大,失重越大；蛋重50～60 g时,受精蛋孵化率与入孵蛋孵化率均较高,分别为83.72％ ～86.67％和67.19％ ～74.23％；雏鸡初生重随蛋重的增加而显著增大,呈强正相关（R=0.973）.In order to understand the Guizhou chicken egg heavy influence on hatching rate, in the same incubation conditions, egg produc- ted by 13 generations of Guizhou yellow chicken were used in the experiments. The results show that： during the whole incubation period, egg weight bigger,loss bigger ; egg weight 50 - 60 g, hatchability of fertilized eggs and hatchability were higher, respectively iS 83.72% - 86.67% and 67.19% -74.23% ; increase in birth weight with egg weight and significant increased, showed strong positive correlation（R = 0. 973）.
