- 摘要:
- 蛋鸡喜好在栖架上休息，在鸡笼中提供栖架可以改善蛋鸡的行为和生理状况。试验选择390只18周龄海兰褐商品蛋鸡，分为个体组、4只群体组和8只群体组依次放入同时装有3种材质（铁质、木质和塑质）栖架的测试笼中进行测试，于测试日当日8∶00～10∶00，14∶00～16∶00，19∶00～21∶00和23∶30～0∶30使用摄像机记录各测试笼中的蛋鸡行为和栖架利用情况，系统地研究在不同群体（饲养密度）条件下，蛋鸡对栖架材质的喜好，以及不同条件下蛋鸡一般行为和栖架行为的差异。结果表明：群体（密度）效应对蛋鸡的一般行为影响显著(P<0.01)，但栖架行为差异不显著，不同时段蛋鸡一般行为表现差异较大(P<0.001)。在夜间喜好试验中，不论个体组、4只群体组，还是8只群体组，对木质栖架的选择均显著高于铁质和塑质栖架(P<0.05)。个体组中，白天蛋鸡在铁质栖架上的转换次数高于其它两组(P<0.05)。在4只群体组中，白天木质栖架上的探究行为显著高于其它两组(P<0.05)。8只群体组中，晚上塑质栖架上的修饰行为低于其它两组(P<0.05)。木质栖架的栖息时间稍高于其它两组。因此，木质栖架更受笼养蛋鸡喜好。
