Abstract:
The impact of global warming on poultry production has gained significant attention over the years. However, our current knowledge and understanding of the mechanisms through which heat stress (HS) resulting from global warming affects the welfare, behavior, immune response, production performance, and even transgenerational effects in poultry are still incomplete. Further research is needed to delve deeper into these mechanisms to gain a comprehensive understanding. Numerous studies have investigated various biomarkers of stress in poultry, aiming to identify reliable markers that can accurately assess the physiological status and well-being of birds. However, there is a significant amount of variation and inconsistency in the results reported across different studies. This inconsistency highlights the need for more standardized methods and assays and a clearer understanding of the factors that influence these biomarkers in poultry. This review article specifically focuses on 3 main aspects: 1) the neuroendocrine and behavioral responses of poultry to HS, 2) the biomarkers of HS and 3) the impact of HS on poultry production that have been studied in poultry. By examining the neuroendocrine and behavioral changes exhibited by poultry under HS, we aim to gain insights into the physiological impact of elevated temperatures in poultry.
摘要:
多年来,全球变暖对家禽生产的影响已引起广泛关注。然而,我们目前对全球变暖导致的热应激(HS)影响福利的机制的知识和理解,行为,免疫反应,生产性能,甚至在家禽中的跨代效应仍然不完整。需要进一步的研究来深入研究这些机制,以获得全面的理解。许多研究已经调查了家禽压力的各种生物标志物,旨在确定可靠的标记,可以准确评估鸟类的生理状态和健康状况。然而,不同研究报告的结果存在显著差异和不一致.这种不一致突出了需要更标准化的方法和测定,以及更清楚地了解影响家禽中这些生物标志物的因素。这篇综述主要集中在3个方面:1)家禽对HS的神经内分泌和行为反应,2)HS的生物标志物和3)HS对家禽生产的影响已在家禽中进行了研究。通过检查HS下家禽表现出的神经内分泌和行为变化,我们的目标是深入了解温度升高对家禽的生理影响。
