Title: | Associative learning by cattle to enable effective and ethical virtual fences | Contributor(s): | Lee, Caroline (author); Henshall, John M (author); Wark, Tim J (author); Crossman, Chris C (author); Reed, Matt T (author); Brewer, Heather G (author); O'Grady, Julian (author); Fisher, Andrew (author) | Publication Date: | 2009 | DOI: | 10.1016/j.applanim.2009.03.010 | Handle Link: | https://hdl.handle.net/1959.11/15931 | Abstract: | An ability of cattle to readily associate a non-aversive audio cue (conditioned stimulus) with an aversive but non-noxious electric shock (unconditioned stimulus) should enable virtual fences to control cattle in an ethical manner similar to conventional electric fencing. The first study was conducted to identify an effective audio cue. Audio (784 Hz tone) and shock (600 V, 250 mW) stimuli were delivered by remote control to GPS collars on five heifers to prevent access to an exclusion zone surrounding a feed trough. An audio cue was administered when the animal entered the exclusion zone, followed by a shock if the animal continued to proceed. There was an increase in the proportion of heifers responding favourably to the audio cue by turning, backing up or stopping in sessions 3 and 4 (73%) compared with sessions 1 and 2 (44%). This indicated that cattle associated the audio cue with the electric shock and learnt to avoid the trough. The main study examined whether cattle location can be controlled by an audio conditioned stimulus without the presence of a visual cue. Weeks 1 and 2 tested heifers' learning of the association between an audio conditioned stimulus and an electric shock reinforcer. In week 3, the effect of dispensing with the conditioned stimulus was tested. | Publication Type: | Journal Article | Source of Publication: | Applied Animal Behaviour Science, 119(1-2), p. 15-22 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1872-9045 0168-1591 |
