摘要: 为了解热应激对肉牛生产的影响及预防热应激的调控措施,该文主要从肉牛的各 项生化指标、生产性能、繁殖性能等方面阐述了热应激对肉牛的影响,同时基于此总结并归纳 了关于肉牛热应激的调控措施。各类研究发现,热应激对肉牛的各类生理行为、生化指标、生 产性能、繁殖性能、免疫功能有较大负面影响。另外,各类研究对于肉牛的热应激预防针对性 地提出调控措施,包括物理设施防控、饲料营养调控及饲养管理调控等,以期解决在南方地区 进行肉牛养殖面临的热应激问题。基于此,该文综述了夏季高温下热应激对于肉牛生产的影 响以及热应激的调控举措,以期为南方地区热应激条件下肉牛养殖提供参考。

Abstract: In order to understand the effects of heat stress on beef cattle production and take measures to prevent heat stress,this paper mainly expounds the influence of heat stress on beef cattle from the aspects of various biochemical indexes,production performance,reproductive performance and so on. Meanwhile,based on this,the regulation measures on heat stress of beef cattle are summarized. Various studies have found that heat stress conditions have great negative effects on various physiological behaviors, biochemical indexes, production performance,reproductive performance and immune function of beef cattle. In addition,various studies have put forward various regulatory measures for the prevention of heat stress in beef cattle,including prevention and control of physical facilities,regulation of feed nutrition and regulation of feeding management,so as to solve the problem of heat stress in key beef cattle breeding in southern China. Based on this,this paper summarized the influence of heat stress on beef cattle production under high temperature in summer and the regulation measures of heat stress,in order to provide reference for beef cattle breeding under heat stress conditions in southern China.
