摘　　要：论文简述了奶牛酮病的主要发病原因,及其对产奶量、乳汁成分、繁殖性能的影响和血酮的测定方法,以血清β-羟丁酸(β-Hydroxybutyrate,BHB)1 200μmol/L作为区分健康奶牛和亚临床奶牛的临界浓度,还概述了国内外学者对奶牛酮病预防措施的最新研究情况,预防措施包括防止奶牛产前过肥或过瘦、增强奶牛食欲、使用添加剂、避免劣质饲料和应激因素等,此外,有条件的奶牛场还应及时建立酮病监测和预测制度。This review gave a brief overview of the main etiology of ketosis, effects of the disease on milk yield, components, reproductive performance, and measuring methods of serum ketone body. The cut-off of 1 200 μmol/L β -Hydroxybutyrate concentrations is used for distinguishing subclinical ketosis from healthy cows. The domestic and international scholars＇ latest reports about preventive measures of dairy cows ketosis were introduced in detail. The measures included preventing over-conditioning or too thin cows before calving, improving feed intake, feeding supplementation, avoiding poor quality feed and stress factors and so on. In addition, dairy farmers should carry out the monitoring and prediction programmes.
