Rumination time, chewing time and drinking time are indicators that can be assessed in case of cow disease. In this research, two groups of cows were formed: cows with subclinical ketosis (SCK; = 10) and healthy cows (HG; = 10). Behaviour such as walking activity, feeding time with head position up, feeding time with head position down, change of activity and average, minimal and maximal ambient temperature of cows were recorded by the RumiWatch noseband system (RWS; RumiWatch System, Itin+Hoch GmbH, Liestal, Switzerland). The RWS comprises a noseband halter with a built-in pressure sensor and a liquid-filled pressure tube. Data from each studied cow were recorded for 420 h. According to the results of our study, it was determined that cows diagnosed with subclinical ketosis showed a tendency to change their activity more frequently. Our data indicates that minimal and maximal ambient temperatures are related with SCK.
反刍时间、咀嚼时间和饮水时间是在奶牛患病时可进行评估的指标。在本研究中，组建了两组奶牛：亚临床酮病奶牛（SCK组；n = 10）和健康奶牛（HG组；n = 10）。通过瘤胃监测鼻带系统（RWS；RumiWatch System，伊廷+霍赫有限公司，瑞士利斯塔尔）记录诸如行走活动、抬头采食时间、低头采食时间、活动变化以及奶牛的平均、最低和最高环境温度等行为。RWS包括一个带有内置压力传感器的鼻带缰绳和一根充液压力管。对每头研究奶牛的数据记录420小时。根据我们的研究结果，确定被诊断为亚临床酮病的奶牛更频繁地改变其活动的倾向。我们的数据表明，最低和最高环境温度与亚临床酮病有关。
