【摘要】 氧化应激是指机体面对各种风险因子的刺激时，体内活性氧类生成与抗氧化防御功能之间的平衡发生紊乱，从而造成机体组织功能损害，引发相关疾病。花青素具有多重生物功效，能够增强多种动物组织、器官和细胞的抗氧化能力，缓解氧化应激造成的损伤，因而受到越来越多的关注。文章概述了花青素的结构、理化性质和生物活性，介绍了其在畜禽生产中缓解氧化应激作用的研究进展，以期为花青素作为天然免疫增强剂和抗氧化剂的应用提供参考。更多还原

【Abstract】 Oxidative stress refers to the imbalance between the generation of reactive oxygen species in the body in response to various risk factors and the antioxidant defense mechanisms, leading to tissue damage and the onset of related diseases. Anthocyanins, with multiple biological effects, have the ability to enhance the antioxidant capacity of various animal tissues, organs, and cells, alleviating damage caused by oxidative stress. As a result, anthocyanins have gained increasing attention. The article provides an overview of the structure, physicochemical properties, and biological activities of anthocyanins. It also introduces the research progress on the role of anthocyanins in alleviating oxidative stress in livestock and poultry production. The aim is to provide a reference for the application of anthocyanins as natural immune enhancers and antioxidants.更多还原
