Establishing fresh cow monitoring procedures is considered beneficial for cow health, welfare, and productivity. However, they are time consuming and require the cows to be locked up, which restricts their natural behavior. In this study, different fresh cow monitoring procedures were evaluated. Two experiments were conducted to determine: (1) the duration of various examinations and treatments; (2) the time cows remain locked up in headlocks; and (3) the proportion of examination and treatment times relative to the total headlock time. In advance, standard operating procedures were established. Three veterinarians conducted the examinations and treatments based on changes in milk yield, clinical symptoms, and alarms by an accelerometer system. The headlock time was evaluated for three workflow strategies, which differed in the order of examinations and treatments. To determine the duration, cameras were installed, and the video footage was analyzed. The examinations lasted between 1 and 227 s, and the cows were locked up in headlocks between 0.01 and 1.76 h. The lock-up times differed significantly among the three strategies, as well as the proportion. This study provides information that can be used as a basis for the development of time-efficient strategies, and to minimize the impact on cows' time budgets.
建立新鲜奶牛监测程序被认为对奶牛的健康、福利和生产力有益。然而，这些程序耗时且需要将奶牛关起来，这限制了它们的自然行为。在本研究中，对不同的新鲜奶牛监测程序进行了评估。进行了两项实验以确定：（1）各种检查和治疗的持续时间；（2）奶牛被锁在头枷中的时间；（3）检查和治疗时间相对于总头枷时间的比例。事先制定了标准操作程序。三名兽医根据产奶量变化、临床症状和加速度计系统发出的警报进行检查和治疗。对三种工作流程策略的头枷时间进行了评估，这三种策略在检查和治疗顺序上有所不同。为了确定持续时间，安装了摄像头并分析了视频片段。检查持续时间为1至227秒，奶牛被锁在头枷中的时间为0.01至1.76小时。三种策略的锁定时间以及比例差异显著。本研究提供的信息可作为制定高效策略的基础，并尽量减少对奶牛时间预算的影响。
