摘　　要： 【目的】探讨富集环境材料对肉鸡福利水平的影响。【方法】选择健康状况良好、体重为(368.18±1.03)g的600只22日龄AA肉公鸡,随机分在栖架、玩具、沙粒、栖架+玩具+沙粒的复合组及对照5个组中,每个处理3个重复,每个重复40只鸡。【结果】结果表明:增加栖架和玩具可更好的满足肉鸡日常行为需要,减少肉鸡恐惧感,改善羽毛质量和步态评分,促进骨骼发育,降低血液中H/L值。而提供沙粒对AA肉鸡的福利指标没有显著影响。【结论】增加栖架或玩具可在一定程度上改善AA肉鸡的福利水平。 [Objective]This article aimed at investigating the effects of environmental enrichment materials on broiler welfare. [Method]600 healthy AA broilers weighed（368. 18±1.03）g at 22 days were allocated into four environmental enrichment treatments,including perch, toy, sand, perch toy sand, and another control group, three replicates per treatment, forty broilers per replicate. [Result]The results showed that adding perches and toys can satisfy broilers daily behavior requirement, reduce their scariness, improve the feather condition,increase the gait score and promote the skeleton development, degraded the Heterophil to Lymphocyte[H/L] . But adding sand didn＇t make significant effects on broilers＂ welfare indicators. [Conclusion] The results indicated adding perches or toys could improve the broiler welfare.
