| 1 | Effects of Dietary Picria felterrae Lour Extracts on Serum Biochemical Indexes and Immune Function of Guangxi Partridge Chickens显示文摘[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. | Yang Cui Bi Xianda Hu Tingjun Yang Jian Huang Hongye Tan Honglian Peng Jianbo Luo Wenjuan Li Lu Li Chunjie Liao Yuying Yang Jiahuang | 2018 | Animal Husbandry and Feed Science2018，10，1： | 0 |
