Un indicateur acoustique inattendu d'émotions positives chez le cheval

Abstract : Assessing positive emotions is crucial for identifying how animals perceive the conditions offered. However, today there is a crucial lack of indicators. However, there are some hints that some non-vocal sounds may reflect positive emotions in animals. In other species of ungulates, there are a few reports indicating that they may be produced more in positive situations. We supposed that snort may result from a physiological change following a positive emotion of low intensity, reflecting the psychologic state of the animal. Results obtained from 48 horses living in two “extreme” conditions (“classical life” vs “naturalistic-like” conditions) show that snort production was significantly associated with positive situations (e.g. while feeding; in pasture) and with ears in forward or sidewards positions (reflecting a more positive internal state). Moreover, the frequency of snorts was especially negatively correlated with the total chronic stress score (reflecting compromised welfare). These results converge to indicate that snorts could reflect a positive emotional state, at least outside the working situation (not tested yet).
