Fermentation of feed with probiotic and biofunctional properties has gained global attention for its potential to enhance digestive absorption and improve overall functional quality. This study investigates the antioxidant capacity and expression of antioxidant-related genes in broiler chickens fed with fermented corn gluten meal (FCGM) containing mixed microbial cultures. Seventy-two male Yellow-Feathered broiler chickens were randomly assigned to 2 groups, each consisting of 3 replicates, and were fed experimental diets containing either corn gluten meal or FCGM for 42 d. The antioxidant capacity of FCGM was assessed in vivo. Chickens fed with FCGM exhibited significant increases in serum glutathione concentration, as well as enhanced activities of total superoxide dismutase, glutathione peroxidase, and catalase (CAT) in their serum. Similar trends were observed in the liver, specifically in the activities of glutathione peroxidase and CAT. Additionally, the expression levels of key antioxidant-related genes in the liver, such as glutathione synthase, superoxide dismutase 1, superoxide dismutase 2, CAT, and glutathione peroxidase 1, were examined. The results indicated that FCGM significantly enhanced antioxidant capacity in broiler chickens. This study highlights the potential benefits of utilizing solid-state fermentation with mixed microbial cultures to improve the antioxidant properties of corn gluten meal, thereby contributing to the overall health and well-being of broiler chickens.
具有益生菌和生物功能特性的饲料发酵因其增强消化吸收和改善整体功能质量的潜力而受到全球关注。本研究调查了饲喂含有混合微生物培养物的发酵玉米蛋白粉（FCGM）的肉鸡的抗氧化能力及抗氧化相关基因的表达。72只雄性黄羽肉鸡被随机分为2组，每组3个重复，分别饲喂含玉米蛋白粉或FCGM的实验日粮42天。在体内评估了FCGM的抗氧化能力。饲喂FCGM的鸡血清谷胱甘肽浓度显著增加，血清中总超氧化物歧化酶、谷胱甘肽过氧化物酶和过氧化氢酶（CAT）的活性也增强。在肝脏中也观察到类似趋势，特别是谷胱甘肽过氧化物酶和CAT的活性。此外，还检测了肝脏中关键抗氧化相关基因的表达水平，如谷胱甘肽合成酶、超氧化物歧化酶1、超氧化物歧化酶2、CAT和谷胱甘肽过氧化物酶1。结果表明，FCGM显著增强了肉鸡的抗氧化能力。本研究强调了利用混合微生物培养物进行固态发酵以改善玉米蛋白粉抗氧化特性的潜在益处，从而有助于肉鸡的整体健康和福祉。
