摘　　要：为进一步掌握宁都黄鸡的种质特性和综合评定宁都黄鸡的杂交效果,测定了宁都黄鸡从开产至210日龄的蛋重,统计分析了杂交、开产日龄和开产前体重对宁都黄鸡蛋重的影响。结果显示:虽然杂交试验鸡含有外来品种伊莎鸡的血缘已非常少,但仍然会增加蛋重;开产日龄对蛋重的影响非常大,且这种影响会持续很长一段时间,过早开产的鸡只所产的鸡蛋会长期偏小。In order to provide a theoretical basis to further understand characteristics of ＇Ningdu Yellow＇ Chicken germplasm and comprehensively assess the effect of ＇Ningdu Yellow＇ Chicken hybrids, egg weight from the open production to 210 day-old was measured, and the impact of the hybridization, age of first egg and open production weight on egg weight was statistical analyzed. The results showed that although hy- bridization chicken had very little blood of exotic species Isa, but its egg weight would still increased. The ef- fect of open production age on egg weight was very large, and this effect wou opened production too early whose eggs would be small in a long term.
