摘要

开发了一种电子监测仪器,用于记录每天躺着的奶牛占用奶牛隔间的时间。该仪器还记录了隔间被占用的时间超过5分钟的次数。该设备用于评估具有不同地板梯度的无唇混凝土地板隔间的占用情况。标准长度为2.25 m,但落差为50、100或150 mm的隔间,分别被占用520、499和399±22.5分钟/天。150毫米的隔间每天被占用的时间明显短于100毫米(P <0.01)或50毫米(P <0.001)隔间。随着楼层坡度的增加,占用事件的平均持续时间有减少的趋势。

The use of an electronic monitoring device to record the effect of cow cubicle floor gradients on cow occupancy

An electronic monitoring instrument was developed to record the amount of time during which cow cubicles are occupied daily by recumbent cows. The instrument also recorded the number of times the cubicle was occupied for periods of greater than 5 min. The equipment was used to assess the occupancy of lipless concrete floored cubicles having different floor gradients. Cubicles of standard length 2.25 m, but with falls of 50, 100 or 150 mm, were occupied for 520, 499 and 399 ± 22.5 min/day, respectively. The 150-mm cubicles were occupied for significantly shorter periods per day than either the 100-mm (P < 0.01) or 50-mm (P < 0.001) cubicles. There was a tendency for the average duration of an occupation incident to decrease as the floor gradient increased.
