摘 要:
本文针对我国优良地方品种北京油鸡,研究栖木的倾斜角度、高度、截面形状3个因素对北京油鸡栖息行为的影响。通过对栖息行为的连续观察,结果表明,北京油鸡的栖息行为在观察时间段中(7∶00~18∶00)均有发生。60°栖架低层、中层的栖息次数显著高于高层(P<0.05),40°栖架中层、高层的栖息次数显著高于低层(P<0.05),20°栖架低层的栖息次数高于中层、高层。30 cm栖木上鸡的栖息次数显著高于40 cm和50 cm栖木(P<0.05),40 cm、50 cm栖木上鸡的栖息次数没有显著差异。矩形和圆形栖木上鸡的栖息次数显著高于梯形栖木(P<0.05),矩形栖木上鸡的栖息次数高于圆形栖木上鸡栖息次数。

摘 要:
Beijing oil chicken is one of the eminent local hen breeds in China.In this experiment,20 Beijing oil chickens fed in perch system were selected as experimental animals.Angles,heights and sections of perch were changed.Conclusions were as follows.Through a whole-day′s constantly observation from 7∶00 in the morning to 18∶00 in the afternoon,the perching behavior happened all day long in every time-area.Number of hens stayed on perch in low and middle height was significantly higher than perch in high height when the perch angle was 60 degrees(P<0.05).Number of hens stayed on perch in high and middle height was significantly higher than perch in low height when the perch angle was 40 degrees(P<0.05).Number of hens stayed on perch in low height was higher than perch in high and middle height when the perch angle was 20 degrees.Number of hens stayed on perch with 30 cm heights was significantly higher than perch with 40 cm and 50 cm heights(P<0.05),and there was no significant difference between perch with 40 cm and 50 cm. Number of hens stayed on perch with rectangle and circle sections was significantly higher than perch with trapezoid section(P<0.05),and number of hens stayed on perch with rectangle section was higher than perch with circle section.
