Abstract: 【Objective】 The aim of this study was to evaluate the effects of Tetrastigma hemsleyanum leaves powder (THL) on growth performance,serum antioxidant,immune function and jejunum morphology of Chongren patridge chickens.【Method】 A total of 360 50-day-old Chongren patridge female chickens were randomly divided into 5 groups with 6 replicates per group and 12 hens per replicate.Hens in control group were fed a basal diet,and hens in experimental groups were fed the basal diet supplemented with 0.5%,1%,2% and 4% THL,respectively.The experiment lasted for 56 days.After the completion of the experiment,weight was utilized as the repetition unit,and feed intake was recorded for calculating the growth performance index.Blood and intestinal tissue samples were collected,serum antioxidant and immune indexes were detected,jejunum tissue sections were prepared and jejunum morphology was observed.The villus height and crypt depth of jejunum were measured,and the V/C ratio was calculated.【Result】 Compared with control group,the ratio of feed to gain (F/G) of Chongren patridge chickens supplemented with 1% THL was significantly decreased (P < 0.05),the contents of immunoglobulin A (IgA),IgM,transforming growth factor β (TGF-β) and the activity of glutathione peroxidase (GSH-Px) in serum were significantly increased (P<0.05).The contents of tumor necrosis factor-α (TNF-α) and malondialdehyde (MDA) were significantly decreased (P<0.05).The contents of IgA and TGF-β in serum were significantly increased (P<0.05),and the contents of interleukin-1β (IL-1β) and TNF-α in serum were significantly decreased (P<0.05) after adding 2% THL.The serum TGF-β content was significantly increased (P<0.05),and the serum IL-1β content was significantly decreased (P<0.05) after the supplementation of 4% THL.The villus height and V/C of jejunum were significantly increased after diets supplemented with 0.5% and 1% THL (P<0.05).【Conclusion】 Dietary supplementation of 0.5% to 4% THL could promote the growth,enhance body immunity and improve intestinal tisste morphology of Chongren patridge chickens to a certain extent.Under the conditions of this experiment, the effect of 1% to 2% THL supplementation was better.
