要:温度是对鸡群健康和生产性能影响最显著的因素之一。本研究针对北京地区典型密闭式
蛋种鸡舍,选取 23-26 周龄的京红 1 号蛋种鸡,对其冬季生产的环境温度及其生产性能进行了连续的
现场测定,从生产实践角度探讨了环境温度对蛋鸡生产性能的影响。结果表明:(1)平均蛋重与平均
日温具有显著相关性(P<);(2)日温差、种蛋合格率在笼架空间分布上有显著性差异(P<),
且日温差较大的中层笼架,其生产性能指标全部低于日温差较小的上层;(3)测试期间舍内最大日温
差是由喷雾消毒导致的,可达 ℃,且该温差与后 2d 的蛋重具有一定的负线性相关性(R=,
P<)。

Abstract:Temperature is one of the most significant factor which affects the health and production
performance of laying hens. In order prehensively discuss the relationship between ambient
temperature and production performance of laying hens in the typical closed hennery in Beijing area, we
selected 23-26 weeks’Jing-Hong 1 breeding hens and continuously tested the ambient temperature and
production performance. The results showed that: (1) the average egg weight had a linear correlation(P<)
with daily average temperature. (2) Diurnal temperature range and yield of hatching eggs had a si
