亚临床型酮病对奶牛健康和生产性能的影响

Effects of Subclinical Ketosis on Health and Performance of Dairy Cows

酮病对奶牛的机体健康和生产性能具较大损伤,若不及时治疗会导致提前淘汰。根据临床特征不同,主要分临床型酮病和亚临床型酮病。亚临床型酮病临床症状不明显,隐秘性强,多发于高产奶牛,若不及时治疗会造成较大影响,带来经济损失。该病原因较多,部分养殖人员认知较差,不利于防控。本文对亚临床型酮病发病原因、特点、临床诊断手段和对奶牛健康危害综合概述,有利于养殖人员更好了解该病,降低损失,促进奶牛养殖业健康发展。

Ketosis has great damage to the body health and production performance of dairy cows.If not treated in time,dairy cows will be eliminated in advance.According to different clinical characteristics,it is mainly divided into clinical ketosis and subclinical ketosis.The clinical symptoms of subclinical ketosis are not obvious,and it is highly secretive.It often occurs in high-yield dairy cows.If not treated in time,it will cause great impact on dairy cows and bring economic losses.At present,there are many causes of the disease,and some farmers have poor knowledge of the disease,which is not conducive to the prevention and control of the incidence rate of the disease.Therefore,in this paper,the causes,characteristics,clinical diagnosis methods and health hazards of subclinical ketosis were comprehensively summarized,which is conducive to better understanding of the disease,reducing losses and promoting the healthy development of dairy cattle breeding industry.
