Aspergillus niger-fermented Ginkgo biloba leaves (FR) and its comparative effect with vitamin E (VE) nonfermented (NF) on growth, lipid metabolism, antioxidant capacity, meat quality of broiler chicks were investigated. In total, 360 one-day-old randomly allocated into 6 dietary treatments, which then denoted as control group (basal diet), VE (containing respectively 15 30 IU/kg all-rac-α-tocopherol acetate in the starter grower phase), NF 0.35% 0.7% FR1, FR2, FR3 groups containing 0.2, 0.35, 0.5% FR 0.4, 0.7, 1.0% phase. The results performance showed that a significant (P < 0.05) reduction feed:gain ratio birds FR2 (22–42 d 1–42 d) was observed when compared groups. With increasing, serum α-tocopherol concentration increased linearly = 0.001). Compared control, broilers had higher high-density lipoprotein concentration, total superoxide dismutase activities, capacity they provided diet. Whereas low-density triglyceride concentrations lower 0.05 or P 0.01) from As increased, abdominal fat 0.002) muscle malondialdehyde 0.001) decreased. Furthermore, 24-h pH, drip loss, cooking loss greatly improved levels increased. Birds fed C16:0 C18:0 but greater C18:2, C18:3, C20:4 than control. conclusion, can improve growth metabolism decreased deposition. Also, improving effects products might result retention peroxidation, evidenced by decrease increase activities.
