仙居三黄鸡产蛋期的生产性能

笼养条件下观察产蛋期的仙居三黄鸡不同体重对产蛋性能的影响。结果表明，体重最大组的只日产蛋量、产蛋率、蛋重、产蛋数、蛋长和蛋宽等指标均为最大；蛋重和蛋宽出现显著性差异，其余指标差异不显著；蛋重、蛋长和蛋宽与母鸡体重呈显著正相关。该研究结果可为仙居三黄鸡及其他蛋鸡的品质改良和开发利用提供理论依据。

Egg Production Performance of Xianju Three Buff Chickens during Laying Period

The effects of different body weights on egg production performance of Xianju three buff chickens was evaluated under cage conditions. The results showed that the daily egg weight, production rate, egg weight, egg numbers, egg length and egg width in heaviest body weight group were the largest. Egg weight and egg width were significantly different among the three groups, whereas the other indexes were not significantly different. Egg weight, egg length and egg width were positively correlated with the hen＇s body weight. Our findings would provide some valuable information on quality improvement, development and use for Xianju three buff chickens and other hen species.
