| 摘 要： | 为了解肉牛热应激研究进展,以"肉牛"、"生产性能"、"生化指标"、"分子调控机制"、"热应激防控"等为关键词,检索、总结和归纳了2008—2018年来肉牛热应激相关文献资料。研究发现:一方面,热应激可降低肉牛的生产性能、繁殖性能、免疫功能及抗氧化功能;激活肉牛交感-肾上腺髓质轴(SAM),下丘脑-垂体-肾上腺皮质轴(HPT)及下丘脑-垂体-甲状腺轴(HPA);另一方面,热应激条件下肉牛可通过血液中miRNAs调控靶基因表达进而参与机体抗热应激反应。但在肉牛耐热基因筛选方面及热应激条件下肉牛营养标准的研究尚少,今后研究应根据不同程度热应激进而制定热应激条件下肉牛营养标准,在筛选肉牛耐热基因方面进行深入研究。

| Abstract: | In order to understand the research progress of beef cattle heat stress,literature related to heat stress in beef cattle over 2008-2018 are retrieved by using "beef cattle","production performance","biochemical indicators","molecular regulation mechanism" and "prevention and control of heat stress" as keywords.The retrieved documents are reviewed and analyzed.It is found that:On the one hand,the heat stress reduces the production performance,reproductive performance,immune function and antioxidant function of beef cattle,and activates the sympathetic-adrenal medullary axis (SAN),hypothalamic-pituitary-adrenal cortex axis (HPT) and hypothalamic-pituitary-thyroid axis (HPA);On the other hand,beef cattle can regulate target gene expression by miRNAs in blood under heat stress to participate in anti-heat stress response.However,there are only a few studies on the screening of heat-resistant genes and the nutritional criteria of beef cattle under heat stress.Future studies should focus on exploring optimal nutritional formulates for beef cattle under different degrees of heat stress and screening heat-resistant genes of beef cattle. |
