Abstract: This experiment was conducted to investigate the effects of nano copper,spores of Ganoderma lucidum and soybean isoflavone on growth performance,immune function and antioxidant capacity of Qingyuan Partridge chickens,as to provide reference for the development and application of additives in broiler production.A total of 1 200 1 d chicks were randomly assigned to 4 groups with 10 replicates of 30 birds per replicate.The control group was fed with basal diet (CON),and the birds in treatment groups were supplemented with 2 500 mg/kg nano copper (NC),600 mg/kg spores of Ganoderma lucidum (GLS) and 300 mg/kg soybean isoflavone premix (SI) for 30 d,respectively.At the end of the experiment,plasma and jejunal mucosa were collected to determine the biochemical variables related to antioxidation in plasma and intestinal immune factors.The results showed that,compared with the control group,①the growth performance of chickens was not affected by the three bioactive additives (P>0.05).②GLS increased the thymus ratio (P<0.05).③NC significantly increased the villus to crypt ratio in jejunum.④NC increased activity of glutathione catalase (GSH-Px) in plasma (P<0.05),and decreased jejunal MDA content (P<0.05) significantly.SI significantly reduced both plasmatic and jejunal malondialdehyde (MDA) content (P<0.05),and all three additives increased activity of total superoxide dismutase (T-SOD) in plasma and jejunum (P<0.05) significantly.⑤NC increased immunoglobulin (IgA) content in jejunum (P<0.05),and GLS decreased tumor necrosis factor-α (TNF-α) in plasma and interferon (IFN-γ) in jejunum (P<0.05)significantly.Based on this experiment,NC,GLS and SI did not affect the growth performance of Qingyuan Partridge chickens,while improved the antioxidant capacity.NC increased the villi/crypt ratio,and NC and GLS regulated the secretion of immune factors.Among them,NC had the best effect on antioxidant capacity and GLS had the best effect on immune function.
