摘要

•虚拟围栏（VF）技术可以帮助养牛生产者应用放牧管理实现土地资源目标。•在牧场采用VF时，急性应激和动物福利是需要考虑的重要因素。•在30分钟的时间内，当接收音频或电信号时，VF不会导致成熟的、哺乳期的肉牛心率（HR）增加。•当牛与电线索边界相互作用时，观察到心率增加，但通常在30秒至4分钟内恢复到控制期间的水平。•总体而言，VF对有小牛的成熟奶牛造成的急性应激最小，并且牛在训练后学会了对音频提示警告做出反应并避免电提示。

Influence of virtual fence on heart rate response in beef cattle

•
Virtual fence (VF) technologies can aid cattle producers in applying grazing management for land resource objectives.
•
Acute stress and animal welfare are important factors to consider when adopting VF on rangelands.
•
VF did not cause increased heart rate (HR) to mature, lactating beef cows when receiving audio or electric cues during a 30-minute period.
•
Increased HR was observed when cattle interacted with the electric cue boundary, but HR typically returned to levels observed during a control period within 30 seconds to 4 minutes.
•
Overall, VF caused minimal acute stress to the mature cows with calves and cattle learned to respond to audio cue warnings and avoid electric cues after being trained.
