The aim of this review is to provide dairy farm advisors, consultants, nutritionists, practitioners, and their dairy farmer clients with an additional toolkit that can be used in the assessment of the quality of their dairy cattle nutrition. Cow signs are behavioral, physiological, and management parameters that can be observed and measured. They are detected by examining and observing the cattle. Other physiological parameters such as fecal scoring, rumen fill, and body condition scoring are also included in 'cow signs'. The assessment should be both qualitative and quantitative; for example, is the cattle individual lame and what is the severity of lameness. The 'diagnosis' of a problem should be based on establishing a farm profile of 'cow signs' and other relevant information. Information gathered through assessment of cow signs should be used as an advisory tool to assist and improve decision making. Cow signs can be used as part of an investigation and or farm audit.
本综述的目的是为奶牛场顾问、咨询师、营养师、从业者及其奶牛场客户提供一个额外的工具包，可用于评估奶牛营养质量。奶牛体征是可以观察和测量的行为、生理和管理参数。通过检查和观察奶牛来检测这些体征。“奶牛体征”还包括其他生理参数，如粪便评分、瘤胃充盈度和体况评分。评估应兼具定性和定量；例如，奶牛个体是否跛行以及跛行的严重程度如何。问题的“诊断”应基于建立“奶牛体征”和其他相关信息的农场概况。通过评估奶牛体征收集到的信息应用作咨询工具，以协助并改进决策。奶牛体征可用作调查和/或农场审计的一部分。
