        应激是一种恢复体内平衡的生物适应性反应,由于每个农场都存在大量的应激源,它在每个动物的生产体系中均会发生。热应激是全球家禽面临的最常见的环境挑战之一。大量研究表明,热应激对肉鸡和蛋鸡的健康、福利和生产性能有显著的负面影响。然而,与报道的热应激效应相关的基本机制仍未完全了解。家禽对热应激的适应性反应在本质上是复杂的,它包括对肠道的影响。
        本文就热应激反应对家禽肠道不同方面的影响,包括其生理、完整性、免疫学和微生物群等方面的科学证据进行了客观综述。虽然已经搜集了大量的信息资料,但差距仍然存在。标准化模型的研发对于更好地比较和推断结果至关重要。通过更好地了解热应激对家禽肠道的影响,为开发和应用更有针对性的干预措施提供了可能。

        Effects of heat stress on the gut health of poultry
        Stress is a biological adaptive response to restore homeostasis, and occurs in every animal production system, due to the multitude of stressors present in every farm. Heat stress is one of the most common environmental challenges to poultry worldwide. It has been extensively demonstrated that heat stress negatively impacts the health, welfare, and productivity of broilers and laying hens. However, basic mechanisms associated with the reported effects of heat stress are still not fully understood. The adaptive response of poultry to a heat stress situation is complex and intricate in nature, and it includes effects on the intestinal tract. This review offers an objective overview of the scientific evidence available on the effects of the heat stress response on different facets of the intestinal tract of poultry, including its physiology, integrity, immunology, and microbiota. Although a lot of knowledge has been generated, many gaps persist. The development of standardized models is crucial to be able to better compare and extrapolate results. By better understanding how the intestinal tract is affected in birds subjected to heat stress conditions, more targeted interventions can be developed and applied.
