微生物发酵床微生态养鸡过程鸡的行为观察

Behavior pattern of chicken reared in a fermentation bed

摘要: 为研究微生物发酵床饲养环境下肉仔鸡在白天(8:00~20:00)的行为表现,随机选取9只肉仔鸡进行连续1周的观察。结果表明:微生物发酵床饲养下,鸡的各行为持续时间中,趴卧时间最长,约占80%,而鸡的行走、奔跑及梳羽等运动时间较少,约占10%,且运动主要集中在8:00~10:00和18:00~20:00这两个鸡舍环境温度相对较低的时段。一天中,鸡出现两次采食高峰期和两次饮水高峰期。采食高峰期出现在14:00~16:00和18:00~20:00这两个时段,饮水高峰期出现在14:00~16:00和10:00~12:00这两个时段。此外,肉仔鸡的体温和张嘴率与环境温度密切相关,与之成正比。

Abstract: The effects of rearing chicken in a fermentation bed on their behaviors,e.g.posturing,drinking and feeding,were observed.The results showed that the broilers sat more(about 80% of the time) and moved less(about 10% of the time) on the fermentation bed.The peak of moving around occurred most frequently at 8:00-10:00 and 18:00-20:00,when the atmospheric temperature was lower in a day.The peak of feeding and drinking occurred twice daily,i.e.,the peak of feeding at 14:00-16:00 and 18:00-20:00,and drinking at 10:00-12:00 and 14:00-16:00.Furthermore,the chicken's body temperature and gaping frequency directly correlated to the ambient temperature.
