應激是一種恢復體內平衡的生物適應性反應,由于每個農場都存在大量的應激源,它在每個動物的生產體系中均會發生。熱應激是全球家禽面臨的最常見的環境挑戰之一。大量研究表明,熱應激對肉雞和蛋雞的健康、福利和生產性能有顯著的負面影響。然而,與報道的熱應激效應相關的基本機制仍未完全了解。家禽對熱應激的適應性反應在本質上是復雜的,它包括對腸道的影響。
本文就熱應激反應對家禽腸道不同方面的影響,包括其生理、完整性、免疫學和微生物群等方面的科學證據進行了客觀綜述。雖然已經搜集了大量的信息資料,但差距仍然存在。標準化模型的研發對于更好地比較和推斷結果至關重要。通過更好地了解熱應激對家禽腸道的影響,為開發和應用更有針對性的干預措施提供了可能。
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.
