我国肉牛养殖业不断发展,相应的疾病日渐增多,其中犊牛低温症是生产上常见疾病之一。犊牛低温症是指犊牛饲养在寒冷多风的环境下,其机体散热过多而产热不足导致的体温快速下降的一种营养代谢失衡的临床综合征。以犊牛四肢末梢、耳鼻口、黏膜发凉,肛温降低至36℃以下,对外界反应敏感性下降、卧地不起、嗜睡、心跳缓慢为特征的一种犊牛常见病。为提高养殖人员对犊牛低温症的重视,完善犊牛饲养管理制度,该文根据犊牛低温症的发病规律、发病因素及主要临床症状,提出相应的治疗和预防措施。

With the development of beef cattle breeding industry in China,calf hypothermia is one of the most common diseases in cattle production.Calf hypothermia is a clinical syndrome of nutrition and metabolism imbalance caused by excessive heat dissipation and insufficient heat production in calving in cold and windy environment.A common disease of calves characterized by cold extremities,ear,nose,mouth and mucous membrane,anal temperature below 36℃,decreased sensitivity to the outside world,lying on the ground,lethargy and slow heartbeat.In order to raise the attention of the breeders to the calf hypothermic disease and improve the management system of the calf raising,this paper puts forward the corresponding treatment and prevention measures according to the law of the occurrence of the calf hypothermic disease,the pathogenic factors and the main clinical symptoms.
