摘要 本研究对商业猪舍进行改造以研究稻草对生长猪行为生理的单独影响,探索提高生长猪福利状况的途径。试验选用156头保育床饲养的74.78日龄保育猪(母猪),随机进入试验用生长猪圈舍(稻草丰富圈或贫瘠水泥地面圈),预观察1周后开始为期8周的正试验,试验期观察生长猪不同时段的行为表达,试验期结束后每圈随机挑选3头猪采血.测定皮质醇浓度。结果袁明:在没有其他环境因素影响下,每日添加少量稻草能降低生长猪皮质醇水平(205.51 mg/mL vs.250.76ng/mL),减少应激,减少针对同伴(1.73% vs 8.11%)和针对圈舍(2.38% vs. 15.59%)的探完,增加俯卧(38.93% vs.16.66%)、站立(36.22% vs.21.39%)、走动(12.53%vs.6.24%)、总的探究(71.81% vs.23.71%)和活动(79.98% vs.31.66%),减少侧卧(16.89%vs.57.28%);稻草圈生长猪表现较多的犬坐(7.95% vs.4.68%),但多伴随稻草探究。总之,在普通商业猪舍,每日添加少量稻草是一种简单可行的提高生长猪福利的途径。
