摘　　要：为探讨利用DHI数据分析奶牛酮病发生规律,该文收集了南方某大型牧场一个生产年度的16673条DHI测定数据,采用SPSS分析软件分析β-羟丁酸(BHBA)和丙酮与泌乳阶段、季节和乳成分等的关系。结果表明,泌乳早期,第三、四季度酮病发生率较高,β-羟丁酸与乳糖相关性最强,丙酮与尿素氮的相关性最强。In order to explore the use of DHI(Dairy Herd Improvement,DHI)data to analyze the occurrence patterns of ketosis in cows,this article conducted an in.depth analysis of the DHI measurement data,lactation stages,and seasons of a cattle herd in a large ranch in the south of China for a production year.The results indicate that in the early lactation stage,the incidence of ketosis is higher in the third and fourth quarters,βHydroxybutyric acid has the strongest correlation with lactose,while acetone has the strongest correlation with urea nitrogen.
