The increase in global temperature and consumers' welfare has increased the use of phytogenic feed additives (PFA) to mitigate the negative effects of heat stress on chickens in recent years. Various bioactive compounds capable of improving the thermotolerance of broiler chickens during exposure to thermal challenges have been identified in different plant species and parts. This review is an overview of the roles of bioactive compounds of different PFA, such as polyphenols and flavonoids, antioxidants, growth-promoting and immune-modulating agents, in heat stress management in broiler chickens. Common PFA in use, particularly in tropical environments, are also discussed. An understanding of the roles of the PFA in chickens' thermotolerance could further stimulate interest in their use, thereby improving the birds' productivity and addressing consumers' concerns. This review collates the existing data on the roles of herbs in mitigating heat stress on chickens and highlights future research perspectives.
近年来，全球气温上升以及消费者对福利的关注促使植物源饲料添加剂（PFA）的使用增加，以减轻热应激对鸡的负面影响。在不同植物物种和部位中已鉴定出多种能够提高肉鸡在热应激期间耐热性的生物活性化合物。本文综述了不同PFA的生物活性化合物，如多酚、黄酮类化合物、抗氧化剂、生长促进剂和免疫调节剂，在肉鸡热应激管理中的作用。还讨论了目前常用的PFA，特别是在热带环境中的使用情况。了解PFA在鸡耐热性中的作用可能会进一步激发人们对其使用的兴趣，从而提高鸡的生产力并解决消费者的担忧。本文综述整理了关于草药在减轻鸡热应激方面作用的现有数据，并突出了未来的研究方向。
