为了解庄河大骨鸡现有群体育成期的生长特点，本研究对庄河大骨鸡育成期720余只母鸡和100余只公鸡的体重进行了3个时间点的测定，深入分析了群体的增重和变异情况。研究发现，除8w母鸡群体外，其他时间点的公母鸡群体的体重和增重变异度均超过10%，母鸡的变异度高于公雏；不仅公母雏间生长发育规律不同，而且同性别群体内部生长发育规律也呈现明显的多样性。

In order to have knowledge about growth characteristics during growing period for Zhuanghe Dagu chicken, data of body weight was acquired at 3 different age for more than 720 hens and 100 roost-ers during growing period and the weight gain and its variation were further analyzed. The results showed that all variations of body weight and weight gain for hens and roosters except for hens at 8w age were more than 10%. The variations of hens were higher than roosters. Not only there was a differ-ence of growth between male and female, but also there was diversity in the same sex.
