Phytogenic feed additives have been largely tested in poultry production with the aim to identify their effects on the gastrointestinal function and health, and their implications on the birds' systemic health and welfare, the production efficiency of flocks, food safety, and environmental impact. These feed additives originating from plants, and consisting of herbs, spices, fruit, and other plant parts, include many different bioactive ingredients. Reviewing published documents about the supplementation of phytogenic feed additives reveals contradictory results regarding their effectiveness in poultry production. This indicates that more effort is still needed to determine the appropriate inclusion levels and fully elucidate their mode of actions. In this frame, this review aimed to sum up the current trends in the use of phytogenic feed additives in poultry with a special focus on their interaction with gut ecosystem, gut function, in vivo oxidative status and immune system as well as other feed additives, especially organic acids.
植物源饲料添加剂已在家禽生产中进行了大量试验，目的是确定它们对胃肠功能和健康的影响，以及它们对家禽全身健康和福利、鸡群生产效率、食品安全和环境影响的作用。这些源自植物、由草药、香料、水果和其他植物部分组成的饲料添加剂包含许多不同的生物活性成分。回顾已发表的关于添加植物源饲料添加剂的文献，发现其在家禽生产中的有效性存在相互矛盾的结果。这表明仍需要更多努力来确定合适的添加水平并充分阐明其作用方式。在此框架下，本综述旨在总结家禽使用植物源饲料添加剂的当前趋势，特别关注它们与肠道生态系统、肠道功能、体内氧化状态和免疫系统以及其他饲料添加剂（尤其是有机酸）的相互作用。
