摘　　要：随着奶畜养殖业集约化程度的不断提高,如何避免热应激对奶畜养殖业乃至畜牧业造成重大的影响成为集约化牧场亟待破解的难题之一。热应激会引起动物生产性能、免疫力及繁殖性能下降等一系列变化。研究发现,微量元素铬(Chromium,Cr)对热应激引起的多种不良反应有抑制作用,从而减轻对动物机体的危害。本文结合了国内外学者对铬在奶畜热应激下的作用研究,综述了铬对奶畜热应激的调控作用及其研究进展。With the rapid development of intensified dairy livestock industry,how to avoid the huge impact of heat stress on dairy livestock even on livestock industry has become a challenge requiring urgent attention in intensified farms.Heat stress may lead to a series of changes including decreaced performance,immunity and reproductive performance.It is reported that trace element Chromium(Cr)can inhibit the adverse effects caused by heat stress and mitigate the harm to animals.This paper reviews the regulatory effects and research progress of chromium on heat-stressed dairy animals,based on the research findings of domestic and international scholars.
