Environmental stress poses serious threats to animal welfare and production, particularly in poultry, which are susceptible to such stress. It can increase susceptibility to diseases and infections, reduce growth rates and reproductive performance, and increase behavioral issues. Environmental stress caused by conventional housing conditions can negatively affect well-being and productivity. High temperature, overcrowding, poor ventilation, insufficient lighting, and wire cages are some of the most prominent stressors in conventional housing systems. To address environmental stress in chicken farms, some strategies and tools, such as using anti-stress feed additives and enriching cages, can help improve bird behavioral activities and welfare. Breeders can improve overall bird performance by implementing these strategies and creating a more enriched and comfortable environment. Thus, this review discusses the importance of using different feed additives and environmental enrichment materials to reduce stress in chicken farms (broiler and layer) and improve bird productivity and well-being.
环境应激对动物福利和生产构成严重威胁，在家禽中尤为如此，因为家禽易受此类应激影响。它会增加对疾病和感染的易感性，降低生长速度和繁殖性能，并增加行为问题。传统养殖条件造成的环境应激会对家禽的健康和生产力产生负面影响。高温、过度拥挤、通风不良、光照不足以及铁丝笼是传统养殖系统中一些最突出的应激源。为解决养鸡场的环境应激问题，一些策略和工具，如使用抗应激饲料添加剂和丰富养殖笼舍，有助于改善家禽的行为活动和福利。养殖者可通过实施这些策略并营造更丰富舒适的环境来提高家禽的整体性能。因此，本综述讨论了使用不同饲料添加剂和环境富集材料来减轻养鸡场（肉鸡和蛋鸡）应激、提高家禽生产力和福利的重要性。
