Effect of Ligustrum Lucidum on Muscle Antioxidant Capacity and GPx4 Gene Expression of AA Broilers

The experiment was designed to investigate the effects of dietary supplementation with raw Ligustrum lucidum(LL)on antioxidant capacity,shelf life and GPx4 expression of broilers muscle.Three hundred and twenty one-day-old Arbor Acres broilers were randomly allocated to 4 treatments.Control group were fed basal diets,experimental groups were given a basal diet supplemented with 5 mg/kg flavomycin,0.5% or 1% LL.The result showed that compared with the control group,diets supplemented with LL improved antioxidant capacity and inhibited MDA content of broiler muscle;1% LL had positive effect on the enzyme activities of SOD and GSH-Px(P0.05);the TNB-N of meat shelf-life tended to decrease,and in the 5th day it was significantly lower than the control group(P0.05);1% LL had positive effect on the expression of GPx4 of broilers muscle(P0.05).It showed that LL could increase antioxidant capacity of broiler muscle from molecular level,thereby inhibit the corruption of chicken.
