| 【目的】探讨栖架式舍饲散养模式对蛋鸡行为与鸡舍环境的影响。【方法】采用舍内栖架散养形式，按照采食区、饮水区、栖息区、活动区和垫料区进行鸡舍内立体分布设计，并配置栖木、采食底网、料线、水线以及产蛋箱等规模饲养设施，建立栖架式舍饲散养模式，以传统全阶梯三层笼养模式为对照，观察8～10周龄海兰褐蛋鸡的各种行为，并检测鸡舍内的NH3、CO2和H2S质量浓度。【结果】与传统笼养相比，栖架散养蛋鸡的趴卧平均频次、趴卧持续时间、行走持续时间、舒展平均频次与舒展持续时间分别显著增加733.33%，6 388.24%，102.44%，287.72%和78.36%(P＜0.05)，站立、采食与饮水的平均频次分别显著降低68.82%，67.01%和60.75%(P＜0.05)，异常行为出现的频次与平均持续时间分别显著下降82.77%和58.04%(P＜0.05)，紧张性静止行为持续时间显著减少了55.05%(P＜0.05)，鸡只神态自然、体表被毛完整。栖架散养鸡舍中的NH3、CO2和H2S日平均含量均低于传统笼养鸡舍，但差异不显著。【结论】栖架式舍饲散养模式利于蛋鸡行为的自由表达，有助于提高其健康福利水平。 |

| Abstract: |
| 【Objective】This study investigated the effects of layer housing range mode with perches on behavior of laying hens and environment of henhouse.【Method】A system with feeding area,drinking area,inhabit area,active area and sawdust area was established.The system also included perches,feeding bottom net,feeding line,drinking line and laying nest.Using the tradition three ladders cage system as control,the behavior and concentrations NH3,CO2,and H2S in henhouse with 8 to 10 weeks old Highland brown chicken were observed and analyzed.【Result】Compare with traditional cage system,the lying frequency and time,walking time,as well as the stretching frequency and time of hens in perches system were increased by 733.33%,6 388.24%,102.44%,287.72% and 78.36% (P<0.05),respectively.The frequencies of standing,feeding and drinking of hens were reduced by 68.82%,67.01% and 60.75% (P<0.05),respectively.The frequency and time of abnormal behavior of hens were reduced by 82.77% and 58.04% （P<0.05),respectively.The time of tonic immobility of hens was decreased by 55.05% (P<0.05).The hens raised in the perches system had natural look and full coating.The daily average concentrations of NH3,CO2 and H2S in perches system were lower than that in the traditional cage system.【Conclusion】The perches system was beneficial to the biological habit of laying hens. |
