反刍动物冷应激作用机理及其调控技术研究进展

Research progress on the mechanism of cold stress in ruminants and its regulation technology

我国北方地区畜牧业具有很大的发展潜力,但冬季持续低温易引起反刍动物的冷应激反应,导致反刍动物的生产性能、免疫力、抗氧化功能降低,给动物生产造成巨大损失。因此,研究反刍动物冷应激的作用机理及其调控技术对北方畜牧业的健康发展具有重要作用。文章综述了反刍动物冷应激的作用机理,以及冷应激对反刍动物生产性能、免疫和血液生理生化指标影响的研究进展,并提出抗冷应激相关的调控技术,为反刍动物冷应激相关的研究提供参考。

Animal husbandry in northern China has great development potential,but the continuous low temperature in winter can easily cause cold stress response of ruminants,which leads to the reduction of ruminant performance,immunity,antioxidant,and other functions,and causes huge losses to animal production.Therefore,it is important to study the mechanism of cold stress and its regulation technology for the healthy development of animal husbandry in northern China.The paper reviews the mechanism of cold stress in ruminants,as well as the research progress on the production performance,physiological immunity and blood physiological and biochemical indexes of ruminants,and proposes the regulation technology related to cold stress,so as to provide a reference for the research on cold stress in ruminants.
