Abstract: 【Obiective】 The experiment was conducted to investigate the effects of different levels of α-mangostin in basic diet on growth performance,immune function,antioxidant capacity and detoxification function of Yellow-feathered broilers,and to provide evidence for its application in broilers.【Method】 A total of 900 1-day-old Ephedra broiers (female) were divided into 6 treatment groups with 6 replicates per group and 25 broilers per replicate.The diets in 6 treatment groups were supplemented with 0,15,30,60,120,and 240 mg/kg α-mangostin in the basal diet, respectively.The experiment lasted for 54 d.One broiler weighted close to the average body weight was selected from each replicate for blood collection and slaughter on the end of experiment,plasma was separated to determine cytokine content and antioxidant index,liver was collected to determine antioxidant and detoxification function related index.【Result】 ①The body weight and average daily gain of broilers increased linearly and quadratically with the increase of α-mangostin supplemental level (P<0.05).There were no significant differences in average daily feed intake,feed to gain ratio and mortality rate of broilers among different treatment groups (P>0.05).②The contents of interleukin-1β (IL-1β),IL-6,IL-10 and malondialdehyde (MDA) in plasma of broilers were significantly affected by different α-mangostin supplemental levels (P<0.05),and the contents of IL-1β,IL-6 and MDA were linearly and quadratically decreased with the increase of α-mangostin supplemental levels (P<0.05),IL-10 content increased linearly and quadratically (P<0.05).③Dietary supplemental different levels of α-mangostin significantly affected the liver malondialdehyde (MDA) content,total superoxide dismutase (T-SOD) and glutathione S transferase (GSH-ST) activities of broilers (P<0.05),and with the increase of α-mangostin supplemental levels,the MDA content was linearly and quadratically decreased (P<0.05),T-SOD activity increased linearly and quadratically (P<0.05),GSH-ST activity increased linearly (P<0.05).【Conclusion】 Dietary α-mangostin could improve growth performance,immune function,antioxidant capacity and detoxification function of Yellow-feathered broilers aged 1 to 54 days.Using the body weight and average daily gain as main evaluation indexes,according to the quadratic curve model,the optimal supplemental levels of α-mangostin in diet were 188 and 156 mg/kg, respectively.
