Abstract：The aim of this experiment was to study the effects of gingerol, allicin and their combination on the growth performance, antioxidant and immune function of 817 chickens. Nine hundred 2-day-old 817 male chickens were randomly assigned to six groups according body weight, each group consisted of six replicates with 25 broilers. The experiment was divided into two stages:2 to 21 days of age and 22 to 41 days of age, and lasted for 40 days. The addition of antibiotic, gingerol and allicin of each group were as follows:A group (no addition), B group (2 mg/kg enramycin), C group (100 mg/kg gingerol), D group (400 mg/kg allicin), E group (stage 1,25 mg/kg gingerol+100 mg/kg allicin; stage 2, 50 mg/kg gingerol+200 mg/kg allicin), F group (stage 1, 50 mg/kg gingerol+200 mg/kg allicin, stage 2, 100 mg/kg gingerol+400 mg/kg allicin), respectively. The results showed as follows:1) compared with groups A and B, the feed/gain (F/G) at 2 to 21 days of age in groups D and E was significantly decreased (P<0.05); average daily gain (ADG) at 22 to 41 days of age and 2 to 41 days of age in group E were significantly increased (P<0.05), and F/G at 22 to 41 days of age and F/G and weight gain cost at 2 to 41 days of age were significantly decreased (P<0.05). 2) Carcass rate in groups C, D, E and F was significantly increased compared with group A (P<0.05). 3) Gingerol and allicin had no significant effects on immune organs indexes (P>0.05). 4) Compared with groups A and B, the content of malondialdehyde (MDA) in plasma in groups C, D, E and F was significantly decreased (P<0.05); the total antioxidant capacity (T-AOC) in plasma in group E was significantly increased (P<0.05); the content of oxidized glutathione (GSSG) in groups C, E and F was significantly reduced (P<0.05); the value of reduced glutathione/oxidized glutathione (GSSG/GSH) in group F was significantly increased (P<0.05). Compared with group A, the contents of immunoglobulin A (IgA) and immunoglobulin G (IgG) in plasma in groups B, C and E were significantly increased (P<0.05); the content of immunoglobulin M (IgM) in plasma of group E was significantly increased (P<0.05). In conclusion, the addition of 25 mg/kg gingerol and 100 mg/kg allicin in the basal diet in 2 to 21 days of age stage, 50 mg/kg gingerol and 200 mg/kg allicin in the basal diet in 22 to 41 days of age stage for 817 chickens can improve growth performance, economic benefits, carcass performance, antioxidant and immune function at the same time.
