Abstract: There is not much research done on the influence of sympathetic training on the emotional reaction
of horses. The aim of the present study was to evaluate the emotional response and the stress level in horses to two sympathetic training methods: (1) with the use of the “round pen technique” (RP), and (2) in which the RP was not applied (SH). Twenty two half-bred Anglo-Arab horses (2.5 years ±3 months of age) were subject to an initial training. Eleven horses were randomly included to the RP method and the other 11 horses for the SH method. Heart rate (HR) and saliva cortisol concentration were measured as indicators of horse emotional arousal and stress level, respectively. The HR values were analysed: at rest, during the habituation period, just after the first saddling and tightening of the girth, during the first time a human leaned over the horse’s back, and during the mounting of the horse. Saliva samples were taken before and 15 min after each training session studied. After saddling, the HR occurred significantly higher when the RP technique was used. The significant increase in saliva cortisol concentration was observed only after the first mounting of the horse. Generally, the use of the RP technique did not involve more important physiological reactions in the trained horses than did the SH method. |

Jezierski T., G. A. (2000). Changes in the horses heart rate during different levels of social isolation. Anim. Sci. Pap. Rep., 18(1), 33–41.
Abstract: Social isolation in horses may be regarded as a stress factor which implies welfare problems. The aim of the experiment was to examine the effect of different levels of transient social isolation and human presence on the heart rate (HR) in horses. Seven horses were used and the experiment was conducted in a tether-stable without boxes. The HR was recorded electronically, continuously for 40 min during the following test situations: all horses in the stable; experimenter approaches the tested horse, other horses being untied and leaving the stable; tested horse staying alone or in the company of one or two stable-mates; the experimenter attempts to calm the isolated horse; outdoor auditory stimuli from other horses. The HR was significantly higher during the whole period of isolation, and depended on how many horses were left as company for the one tested. The highest HR was observed while other horses were leaving the stable and during perception of outdoor auditory stimuli from others. When in the company of two stable mates, the HR was elevated only while other horses were leaving the stable and during auditory stimuli from outdoors. Human presence evoked a significant increase in HR, probably due to conditioning of horses (expecting to be untied and allowed to join the others), irrespectively whether the tested horse was left alone or with one or two stable-mates.
