Preliminary investigations into the ethological relevance of round-pen (round-yard) training of horses.
Recently, training horses within round-pens has increased in popularity. Practitioners often maintain that the responses they elicit from horses are similar to signals used with senior conspecifics. To audit the responses of horses to conspecifics, 6 mare-young-horse dyads, this study introduced them to each other in a round-pen and videoed them for 8 min. These dyads spent significantly more time farther than 10 m apart than they did less than 1 m apart (p < .001). The time they spent less than 1 m apart decreased over the 8-min test period (p = .018). Mares occupied the center of the round-pen and chased youngsters for 0.73% of the test period (p < .001). Mares made all agonistic approaches (p < .001), and youngsters (p = .018) made all investigative approaches. Head lowering and licking-and-chewing were exhibited most when the youngsters were facing away from the mares (p < .001). The frequency of head lowering increased during the test period (p = .027), whereas the frequency of licking-and-chewing did not change. The results bring into question the popular interpretation and ethological relevance of equine responses commonly described in round-pen training and show that mares did not condition young horses to remain in close proximity to them.
