Abstract：This experiment aimed to investigate the effects of Poria cocos extract on the growth performance,intestinal health,and immune function in white-feathered broilers.A total of 1 800 healthy one-day-old Arbor Acres(AA)broilers with uniform body size were randomly divided into three groups,with six replicates per group and 100 broilers per replicate.The control group was fed a basal diet,while experimental groups 1 and 2 received the basal diet supplemented with 50 g/t and 100 g/t of Poria cocos extract,respectively.The test period lasted for 35 days.The results showed that compared with the control group,the average daily gain(ADG)in each experimental group was significantly increased(P＜0.05),and the feed-to-gain ratio(F/G)was significantly decreased(P＜0.05).The activities of serum catalase(CAT)and glutathione peroxidase(GSH-Px),and the concentrations of interleukin-4(IL-4)and immunoglobulin M(IgM)in each experimental group were significantly increased(P＜0.05),while the activity of total superoxide dismutase(T-SOD)and the content of immunoglobulin G(IgG)were significantly decreased(P＜0.05).The villus height(VH)and the ratio of villus height to crypt depth(V/C)in the duodenum,jejunum,and ileum in each experimental grou were significantly increased(P＜0.05),while the crypt depth(CD)was significantly decreased(P＜0.05).The study indicates that dietary supplementation with 50 g/t of Poria cocos extract can effectively improve the growth performance of white-feathered broilers,enhance antioxidant capacity and immune function,promote intestinal morphological development,and improve intestinal health.
