【摘要】 热应激通过上调皮质醇激素，升高血清内毒素含量，上调肠道内炎症、氧化、凋亡水平增加肠道通透性，最终引发机体系统性炎症反应综合征（SIRS）、多器官功能障碍（MODS），给养殖业造成损失。近年来全球温度持续上升，热应激造成的畜牧业损失引起广泛关注。本文总结了热应激影响鸡生产性能、肠道形态结构、肠道屏障功能（包括炎症反应、氧化应激、凋亡水平）的相关研究及机制，旨在为防治家禽高温应激提供理论参考。更多还原

【Abstract】 Heat stress(HS) leads to increased intestinal permeability by up-regulating the levels of cortisol hormone, intestinal oxidation, inflammation and apoptosis, and increase the content of serum endotoxin, eventually induce SIRS and MODS,which will cause losses to animal husbandry. In recent years, due to the continuous rise of global temperature, the loss of animal husbandry caused by heat stress has attracted widespread attention. In this paper, the related research and mechanism of HS affecting chicken performance, intestinal morphological structure and intestinal barrier function in recent years were summarized, including oxidative stress, inflammatory reaction and apoptosis level, which provided theoretical reference for the prevention and treatment of high temperature stress in poultry.更多还原
