Effects of Dietary Marigold Extract Supplementation on Serum Biochemical Indices, Antioxidant and Immune Capacities of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of dietary marigold extract supplementation on serum biochemical indices, antioxidant and immune capacities of broilers. A total of 192 one⁃day⁃old Arbor Acres ( AA) chickens were randomly divided into 3 groups with 8 replicates of 8 chickens each. Chickens in the control group were fed a basal diet and the others in test groups were fed basal diets added with 0.15% and 0.60% marigold extract (the effective composition content of lutein was 30 and 120 mg/kg), respectively. Test period was 42 d. The results showed as follows:compared with the control group, 1) the levels of serum triglyceride and low density lipoprotein cholesterin of broilers in 0.60% marigold extract supplementation group were significantly decreased (P<0.05), while the high density lipoprotein cholesterin level was significantly increased ( P<0.05);2) the serum total antioxidant capacity and activities of superoxide dismutase, glutathi⁃one peroxidase and catalase of broilers at 21 and 42 days of age in 0.15% and 0.60% marigold extract supple⁃mentation groups were significantly increased ( P<0.05);3) the indices of thymus, spleen and bursal of Fab⁃ricius of broilers at 21 days of age in 0. 60% marigold extract supplementation group were significantly in⁃creased ( P<0.05) , the levels of serum immunoglobulin M, immunoglobulin G and interleukin⁃2 were signifi⁃cantly increased by dietary marigold extract supplementation ( P<0.05) , while there were no significant effects on immune organ indices of broilers at 42 days of age with the marigold extract supplementation ( P>0.05) . It is concluded that dietary supplementation with marigold extract can increase the antioxidant and immune capaci⁃ties and regulate lipids metabolism of broiler chickens.关键词
