当前讨论所依据的报告是为了响应乳制品行业对临床疾病数据记录日益增长的兴趣而编写的。主要目标是引入记录和呈现奶牛疾病的指南和标准。考虑了八种对乳制品行业具有经济重要性的临床可识别疾病：产奶热、胎盘滞留、子宫炎、酮症、真胃左侧移位、囊性卵巢疾病、跛行和临床乳腺炎。这些疾病的标准化定义是通过与行业合作伙伴协商建立的。提出了两种总结和报告方法。对于回顾性分析（在总结历史数据以进行遗传评估时使用），例如，Seen 建议使用哺乳期发病风险（累积发病率）。对于当前用于牛群健康监测的分析，建议使用真实的发病率。产奶热和胎盘滞留是后者的例外，因为它们的危险期较短。对于这两种疾病，有哺乳期发病风险的报告。
The report upon which the current discussion is based was prepared in response to the increasing interest of the dairy industry in the recording of clinical disease data. The major objective was to introduce guidelines and standards for the recording and presentation of the diseases of dairy cattle. Eight clinically identifiable diseases of economic importance to the dairy industry were considered: milk fever, retained placenta, metritis, ketosis, left displaced abomasum, cystic ovarian disease, lameness, and clinical mastitis. Standardized definitions for these diseases were established through consultation with industry partners. Two approaches to summarization and reporting were proposed. For retrospective analysis, which is used when historical data are summarized for genetic evaluation for example, lactational incidence risk (cumulative incidence) has Seen recommended. For current analysis, which is used for herd health monitoring, a true incidence rate has been recommended. Milk fever and retained placenta were exceptions to the latter because of their short periods of risk. For these two diseases, lactational incidence risks are reported.
