摘　　要：本试验旨在探讨垫料厚度对黄羽肉鸡生产性能、免疫器官指数、血清生化指标和福利状况的影响。选用1 600只21日龄苏禽黄鸡(公雏),随机分成4组,每组5个重复,每个重复80只鸡,饲养密度为8只/m2。各组锯屑垫料厚度依次为4、8、12、16 cm,试验期为35 d,从22日龄至56日龄。结果表明:垫料厚度对56日龄黄羽肉鸡生产性能、血液常规指标和血清生化指标影响不显著(P>0.05),对垫料水分含量影响显著(P<0.05),且垫料水分含量与垫料厚度呈显著线性关系(P<0.001)。垫料厚度显著影响了肉鸡福利指标中对羽毛污染、羽毛损伤、脚垫炎、胸囊肿积液(P<0.05),其中羽毛污染(P=0.005)、羽毛损伤(P<0.001)、脚垫炎(P=0.007)、胸囊肿积液(P=0.013)均与垫料厚度呈显著线性关系。由此可知,适当增加垫料厚度垫料可以改善垫料质量和56日龄肉鸡的福利状况,本文以16 cm垫料厚度效果最佳。This trial was conducted to evaluate the effects of litter thickness on production performance,im-mune organ indexes,serum biochemical parameters and welfare quality of yellow-feathered broilers. A total of 1 600 21-day-old Suqin yellow-feathered male broilers were randomly allocated 4 groups with 5 replicates per group and 80 birds per replicate（8 birds/m2）. These birds were assigned to litter thickness treatments for 4, 8,12 and 16 cm,respectively. Each treatment was represented by 5 replicates. The experiment lasted for 35 days（ from 22 to 56 days of age）. The results showed that litter thickness had no effects on production per-formance,blood routine parameters,and serum biochemical parameters（ P〉0.05）. The litter moisture content showed significant response to increasing litter thickness（ P〈0.05）,and there was significant linear correlation between litter moisture content and litter thickness（ P〈0.001）. The plumage pollution,plumage damage,and foot pad dermatitis as well as breast blister displayed significant reply to increasing litter thickness（ P〈0.05）, and they were linearly affected by litter thickness（ P=0.005,P〈0.001,P=0.007 and P=0.013,respective-ly）. The findings in this study reveal that increasing properly litter thicknesshas beneficial effects on litter quali-ty and welfare quality of yellow-feathered broilers aged 56 days,and the effects of 16 cm litter thickness are best.
