Effects of Litter Thickness on Production Performance, Immune Organ Indexes, Serum Biochemical Parameters and Welfare Quality of Yellow-Feathered Broilers
摘要
Abstract
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.关键词
