Dairy cattle health monitoring program becomes vital for detecting the febrile conditions to prevent the outbreak of the animal diseases as well as ensuring the fitness of the animals that are directly affecting the health of the consumers. The aim of this study was to validate real-time rectal temperature (RT) data of radio frequency based digital (RFD) thermometer with RT data of mercury bulb (MB) thermometer in dairy cattle.
Two experiments were conducted. In experiment I, six female Jersey crossbred cattle with a mean (±standard error of the mean) body weight of 534.83±13.90 kg at the age of 12±0.52 years were used to record RT for 2 h on empty stomach and 2 h after feeding at 0, 30, 60, 90, and 120 min using a RFD thermometer as well as a MB thermometer. In experiment II, six female Jersey crossbred cattle were further used to record RT for 2 h before exercise and 2 h after exercise at 0, 30, 60, 90, and 120 min. Two-way repeated measures analysis of variance with comparisons by Bonferroni test was done.
Real-time RT data recorded by RFD thermometer as well as MB thermometer did not differ (p>0.05) before and after feeding/exercise. An increase (p<0.05) in RT after feeding/exercise in experimental crossbred cattle was recorded by both RFD thermometer and MB thermometer.
The results obtained in the present study suggest that the body temperature recordings from RFD thermometer would be acceptable and thus RFD thermometer could work well for monitoring real-time RT in cattle.
奶牛健康监测计划对于检测发热状况以预防动物疾病爆发以及确保动物健康至关重要，而动物健康直接影响消费者的健康。本研究的目的是验证基于射频的数字（RFD）温度计的实时直肠温度（RT）数据与奶牛水银体温计（MB）的RT数据。
进行了两项实验。在实验I中，选用6头12±0.52岁、平均（±平均标准误差）体重为534.83±13.90 kg的泽西杂交母牛，使用RFD温度计和MB温度计在空腹时以及喂食后0、30、60、90和120分钟记录2小时的直肠温度。在实验II中，进一步选用6头泽西杂交母牛，在运动前和运动后0、30、60、90和120分钟记录2小时的直肠温度。采用双向重复测量方差分析，并通过Bonferroni检验进行比较。
RFD温度计和MB温度计记录的实时直肠温度数据在喂食/运动前后无差异（p>0.05）。RFD温度计和MB温度计均记录到实验杂交母牛在喂食/运动后直肠温度升高（p<0.05）。
本研究获得的结果表明，RFD温度计记录的体温是可接受的，因此RFD温度计可很好地用于监测奶牛的实时直肠温度。
