摘要
于2009年6、7月在高寒草地观察不同温度条件下放牧青脚麻鸡的行为习性表达。结果表明,当地面温度(距地面1cm)在3～8℃时,牧鸡开始活动;采食行为一般发生在10～37℃;而温度介于15～38℃时,牧鸡求偶;静卧行为通常发生在较高(38～42℃)和较低(低于5℃)的温度条件下。最高采食频率发生在15～27℃。观察发现,早晚牧鸡的活动行为表达没有显著差异(P>0.05)。游憩和采食受瞬时温度影响较其他行为明显。静息、求偶和游憩行为表达在不同性别间差异显著(P<0.05),公鸡静息、求偶和游憩行为显著高于母鸡,但母鸡采食行为明显多于公鸡。
An experiment was conducted to observe the effects of different temperature on the behaviors of free-ranging chicken in the alpine grassland during June-July, 2009. This study showed that chicken be- gan to walk when the temperatures （shaded air temperature 1 cm above soil surface） was 3--8℃, and started foraging behavior while temperatures was 10-- 37 ℃, and began to courtship once temperatures reached 15--38 ℃. Quiescence was often observed at the lowest temperature with the below 5 ℃ and high- est site temperature with the over 38--42 ℃, and the highest frequency of foraging was often observed when temperature was of 15--27 ℃. There＇s no significant difference between frequency of activities in morning and evening （P〉0.05）. Males rested, courted, and groomed significantly more frequently than females did, and females foraged significantly more than that of males （P〈0.05）. Activity patterns, especially quiescence and foraging, were influenced much more by environmental temperature than by time of day.
