[Objective] This trial was to investigate the effect of dietary Picria felterrae Lour extracts on serum biochemical indexes and immune function of Guangxi Partridge chickens. [Method] Totally 500 individuals of 1-day-old Guangxi Partridge chickens were randomly divided into five groups, five replicates each group and 20 chicks each replicate. Groups A, B and C were treatment groups supplemented with 0.70%, 0.35% and0.175% P. felterrae extracts in the basal diet, respectively; group D was a medical control group supplemented with 0.01% colistin sulfate premix in the basal diet; and group E was a control group with basal diet. Serum samples were collected from 10 chickens in each group at 21, 35 and 49 days of age, to analyze the biochemical and immune indexes. [Result] It had no significant impact on serum TP and GLU contents of chickens by adding different levels of P. felterrae extracts in the basal diet(P 〉0.05). However, at 21 and 35 days of age, the TBILI content of chickens in groups A, B and C were extremely lower or significantly lower than that in group E( P〈0.01; P〈0.05). At 35 days of age, the serum AKP activities in groups A, B and C were extremely higher than that in group E(P〈0.01), and the serum GOT activities at 21 and 35 days of age in group C were significantly higher than that in group E(P〈0.05). At 49 days of age, the serum Ig G content in groups A, B and C and the IL-2 content in group B and group C were significantly lower or extremely lower than that in group E( P〈0.05; P〈0.01); the T-AOC content in group B was significantly higher than that in group E(P〈0.05); the GSH content in groups A, B and C were significantly higher than that in group E( P〈0.05). Adding different levels of P. felterrae extracts in the diet significantly decreased the TBILI content, reduced the Ig G, IL-2 and IL-6 contents, and improved the AKP and GOT activities and the T-AOC and GSH contents of Guangxi Partridge chicken. [Conclusion] Adding 0.35% P. felterrae extracts in the basal diet received the best effort. 展开更多
