Selenium is widely acknowledged as an indispensable trace element for humans and various animals, including poultry. The addition of selenium in appropriate doses plays a crucial role in promoting poultry growth and reproduction. Conversely, both deficiency and excessive intake of selenium can pose significant threats to poultry health and production performance. In modern poultry farming, there is an increasing demand for precise nutrient intake, necessitating a comprehensive understanding of the multifaceted role of selenium. This review aimed to compare and contrast the properties and recommended addition amounts of different sources of selenium in poultry feed; to discuss the hazards and mechanisms associated with selenium deficiency or excess in poultry; to summarize the pivotal role that selenium plays in stress states among poultry. Overall, this review seeked to provide a comprehensive overview highlighting the significance of selenium in terms of nutrition and health for poultry while ensuring optimal utilization within poultry production.
硒被广泛认为是人类和包括家禽在内的各种动物不可或缺的微量元素。适量添加硒对促进家禽生长和繁殖起着至关重要的作用。相反，硒的缺乏和过量摄入都会对家禽健康和生产性能构成重大威胁。在现代家禽养殖中，对精确营养摄入的需求日益增加，因此有必要全面了解硒的多方面作用。本综述旨在比较和对比家禽饲料中不同硒源的特性和推荐添加量；讨论家禽硒缺乏或过量相关的危害及机制；总结硒在家禽应激状态中所起的关键作用。总体而言，本综述旨在提供一个全面概述，突出硒在禽类营养和健康方面的重要性，同时确保在家禽生产中实现最佳利用。
