【摘要】：【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%(P0.05),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%(P0.05),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%(P0.05),紧张性静止行为持续时间显著减少了55.05%(P0.05),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] to study the effect of perch house feeding on the behavior of laying hens and the environment of chicken house. [methods] the stereoscopic distribution design of chicken house was carried out according to the feeding area, drinking water area, perch area, activity area and cushion area. The scale feeding facilities such as perch, bottom net, feed line, waterline and egg box were set up to establish the perch and rest feeding model. The behavior of Hailan brown laying hens at the age of 8 ~ 10 weeks was observed, compared with the traditional full-step three-layer cage feeding model. The NH3,CO2 and H2S concentrations in the henhouse were determined. [results] compared with the traditional cage rearing, the average frequency, duration and walking duration of laying hens were measured. The average frequency and duration of stretch were significantly increased by 733.33, 6388.24% and 78.36% (P0.05), respectively, and 102.44%, 287.72% and 78.36% (P0.05), respectively. The average frequency of intake and drinking water decreased 68.82% 67.01% and 60.75% (P0.05) respectively. The frequency and mean duration of abnormal behavior decreased by 82.77% and 58.04% (P0.05), respectively. The duration of nervous static behavior was significantly reduced by 55.05% (P0.05). The daily average contents of NH3,CO2 and H _ 2S in the perched henhouse were lower than those in the traditional cage house, but the difference was not significant. [conclusion] the perched free-range feeding model is beneficial to the free expression of the behavior of laying hens and to the improvement of their health and welfare level.
