應(yīng)激是一種恢復(fù)體內(nèi)平衡的生物適應(yīng)性反應(yīng)，由于每個農(nóng)場都存在大量的應(yīng)激源，它在每個動物的生產(chǎn)體系中均會發(fā)生。熱應(yīng)激是全球家禽面臨的最常見的環(huán)境挑戰(zhàn)之一。大量研究表明，熱應(yīng)激對肉雞和蛋雞的健康、福利和生產(chǎn)性能有顯著的負(fù)面影響。然而，與報道的熱應(yīng)激效應(yīng)相關(guān)的基本機(jī)制仍未完全了解。家禽對熱應(yīng)激的適應(yīng)性反應(yīng)在本質(zhì)上是復(fù)雜的，它包括對腸道的影響。
本文就熱應(yīng)激反應(yīng)對家禽腸道不同方面的影響，包括其生理、完整性、免疫學(xué)和微生物群等方面的科學(xué)證據(jù)進(jìn)行了客觀綜述。雖然已經(jīng)搜集了大量的信息資料，但差距仍然存在。標(biāo)準(zhǔn)化模型的研發(fā)對于更好地比較和推斷結(jié)果至關(guān)重要。通過更好地了解熱應(yīng)激對家禽腸道的影響，為開發(fā)和應(yīng)用更有針對性的干預(yù)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.
