在广泛的系统中管理牲畜的流动具有环境和生产效益。目前使用永久性铁丝网来控制牛;这既昂贵又不灵活。已知牛会对听觉和视觉线索做出反应，我们调查了这些线索是否可以用来操纵它们的行为。25头平均体重为270 kg的贝尔蒙特红牛被随机分为5组。治疗包括线索（听觉，触觉和视觉刺激）和结果（电刺激）的组合。治疗方法分别为单纯电刺激、音频+电刺激、振动+电刺激、光照+电刺激和带电围栏（6 kV）+电刺激。给予线索刺激3秒，然后立即给予1 kV的电刺激（结果）1秒。该实验测试了动物控制或虚拟围栏系统的操作功效。设计了一种项圈-笼头装置，用于携带电子器件、电池和提供刺激的设备，包括原型虚拟击剑装置的音频、振动、光和电。允许牛沿着沿着40 m的小巷行进到一组同伴处并进食，同时记录它们的行进速率和对刺激的反应。虚拟围栏系统原型成功地改变了牛的行为。牛沿着小巷的行进速度证明了与触觉、视觉和听觉线索相关的行为反应的巨大变异性。实验表明，虚拟围栏具有在广泛的放牧系统中控制牛的潜力。然而，需要对更多的牛进行测试，以更好地了解行为差异。进一步的控制实验工作也是必要的，以量化之间的相互作用的线索，后果和牛的学习。(c)2007 Elsevier B.

Managing livestock movement in extensive systems has environmental and production benefits. Currently permanent wire fencing is used to control cattle; this is both expensive and inflexible. Cattle are known to respond to auditory and visual cues and we investigated whether these can be used to manipulate their behaviour. Twenty-five Belmont Red steers with a mean live weight of 270kg were each randomly assigned to one of five treatments. Treatments consisted of a combination of cues (audio, tactile and visual stimuli) and consequence (electrical stimulation). The treatments were electrical stimulation alone, audio plus electrical stimulation, vibration plus electrical stimulation, light plus electrical stimulation and electrified electric fence (6 kV) plus electrical stimulation. Cue stimuli were administered for 3 s followed immediately by electrical stimulation (consequence) of I kV for I s. The experiment tested the operational efficacy of an on-animal control or virtual fencing system. A collar-halter device was designed to carry the electronics, batteries and equipment providing the stimuli, including audio, vibration, light and electrical of a prototype virtual fencing device. Cattle were allowed to travel along a 40 m alley to a group of peers and feed while their rate of travel and response to the stimuli were recorded. The prototype virtual fencing system was successful in modifying the behaviour of the cattle. The rate of travel of cattle along the alley demonstrated the large variability in behavioural response associated with tactile, visual and audible cues. The experiment demonstrated virtual fencing has potential for controlling cattle in extensive grazing systems. However, larger numbers of cattle need to be tested to derive a better understanding of the behavioural variance. Further controlled experimental work is also necessary to quantify the interaction between cues, consequences and cattle learning. (c) 2007 Elsevier B.V. All rights reserved.
