摘要： Magnolol is a multifunctional polyphenol rich in Magnolia officinalis. The objective of this study was to investigate the effects of magnolol on growth performance, carcass traits, antioxidant capacity, and gut health of broiler chickens. A total of 240 1-day-old broilers were randomly allocated into five dietary treatments: control (Ctrl); control diet supplemented with 100, 200, or 300 mg/kg of magnolol (M100, M200, and M300); and control diet supplemented with 200 mg/kg of bacitracin zinc (PC). The results showed that magnolol linearly decreased the feed conversion ratio between d 0 and d 14, linearly decreased the amount of malondialdehyde and increased the activity of total superoxide dismutase (T-SOD) in both serum and ileal mucosa on d 42 with increasing magnolol levels (p < 0.05). Moreover, the ileal villus height, the ileal villus height to crypt depth ratio, and the jejunal gene expressions of SOD1, glutathione peroxidase, and Claudin1 were linearly up-regulated with increasing magnolol levels (p < 0.05). The supplementation of magnolol had no effect on carcass traits or cecal short chain fatty acids (p > 0.05). The results indicated that magnolol could be applied in the diet of broiler chickens to benefit their antioxidant capacity and intestinal health.
