Abstract

Weaving, a common locomotor stereotypy, has been associated with social isolation in stabled horses. In this study we investigated the effect of provision of mirrors on weaving as this may have a similar effect to access to conspecifics. .. The provision ofa mirror significantly reduced the incidence of both stereotypic weaving (P<0.001) and nodding (P<0.05). ... The mirror may mimic visual contact with conspecifics (minimising the social isolation of the stable) and/or provide environmental distraction or additional visual stimuli, altering the horses' perception of the environment and their resultant responses to it. The use of mirrors in the stable appears to be a more effective treatment of weaving than many current popular treatments, including weaving bars.
