广东气候因素对种鸭繁殖力的影响

Effect of climate factors on propagation of breed ducks in Guangdong

调查 1 997～ 1 998年的 1万多套经产种鸭的产蛋率、受精率 ,以及对应的自然环境气候因子气温、湿度、光照等数据 ,采用 SAS软件程序统计气候因素对种鸭产蛋繁殖力的影响 ,结果显示 :相对湿度和气温对产蛋率影响力为显著 (相对湿度呈正相关 ,p <0 .0 5;平均气温呈负相关 ,p <0 .0 5)。

An investigation of egg production rate and fertilization rate was made among over ten thousand egg-laying breed ducks during the period of 1997～1998. The relevant climate factors such as temperature, humidity and lumination were analysed by SAS software program. As a result,relative humidity and temperature acting as significant factors affect egg production rate,which is directly relevant to the relative humidity (p < 0.05) and inversely relevant to average temperature(p <0.05).
