为改善白羽肉鸡的饲养环境及改进日常管理措施提供科学依据,将地面平养的罗斯308肉鸡在鸡舍内分为前中后3个区域,每个区域内各标记50只,分别在17～20日龄和30～33日龄统计标记个体在鸡舍内的活动距离.结果表明:罗斯308白羽肉鸡17～20日龄的活动范围比30～33日龄大;大多数个体的活动范围局限在10m范围内,20日龄时在鸡舍前、中、后部活动范围超出10 m的占比分别为18％、10％和12％,33日龄时分别为12％、8％和6％.白羽肉鸡饲养过程中一旦确定其在舍内的生活空间后一般不会大量迁移到其他地方,容量大的鸡舍,只需隔离出一小间用于安置病弱个体即可.%The chicken coop was divided into three parts (front,middle and rear part) and 50 Rose 308 broilers in each part were labeled under the floor rearing pattern.The activity scope of 50 broilers with 17～30 d old and 30～33 d old in each part was determined to provide the scientific basis for improvement of white feather broiler'feeding environment and daily management.Results:The activity scope of broilers with 17～30 d old is larger than broilers with 30～33 d old and the activity distance of most labeled individuals is within the scope of 10 m.The proportion with over 10 m activity scope of broilers with 20 d old in front,middle and rear part is 18％,10％ and 12％ and the proportion with over 10 m activity scope of broilers with 33 d old in front,middle and rear part is 12％,8％ and 6％ respectively.A small space should be only isolated in the larger-capacity chicken coop for sick and weak broilers because most broilers will not move to somewhere else normally once broilers determine their living space in a chicken coop.
