多胺普遍存在于动植物细胞中，广泛参与生物体内的生理和病理过程。动物体内的多胺有3种来源:食物摄入、肠道微生物合成和细胞合成，其中膳食多胺是主要来源。多胺对动物健康有重要影响，作用于肠道成熟和免疫系统的分化和发育方面;此外，多胺的抗氧化和抗炎作用在心血管疾病等慢性疾病的预防中也发挥重要作用。本文主要从多胺调节肠道上皮细胞的迁移、免疫功能、氧化应激状态和心肌细胞凋亡等方面论述多胺的生理功能及其作用机理，同时还对多胺在畜禽生产中的应用进行阐述，以期为多胺在畜禽生产中的应用提供参考。

Polyamines commonly exist in animal and plant cells and are widely involved in physiological and pathological processes in organisms. There are three sources of polyamines in animal body: food intake, gut microorganism synthesis and cell synthesis, among which dietary polyamines are the main source. Polyamines have important effects on animal health, including intestinal maturation and differentiation and development of the immune system. In addition, the antioxidant and anti⁃inflammatory effects of polyamines also play an im⁃ portant role in...
