Abstract
Simple SummaryIt has been shown that people within the horse industry have preconceived ideas about horse behaviour, temperament and rideability, based solely on the sex of the horse. Such ideas can have welfare implications, if personnel allow bias to affect their interactions with particular horses. Such welfare implications include employment of harsher training methods, and increased horse wastage. The current study explored data on riders’ and trainers’ reports of ridden horse behaviour. Reported sex-related behavioural differences were evaluated based on 1233 responses from the pilot study of the Equine Behaviour and Research Questionnaire (E-BARQ) survey. Results from the study suggest there are some sex-related differences in behaviour between male and female horses; geldings are more likely to chew on rugs and lead ropes when tied, and mares are more likely to move away when being caught in paddock. However, there was no evidence of sex-related differences associated with behaviour when ridden which may warrant further investigation. Findings from this study may be used to educate riders and trainers about the need to regard behaviour and motivation in ridden horses as sex-neutral.Horse trainers and riders may have preconceived ideas of horse temperament based solely on the sex of the horse. A study (n = 1233) of horse enthusiasts (75% of whom had more than 8 years of riding experience) revealed that riders prefer geldings over mares and stallions. While these data may reflect different sex preferences in horses used for sport, they may also reduce the chances of some horses reaching their performance potential. Further, an unfounded sex prejudice is likely to contribute to unconscious bias when perceiving unwanted behaviours, simplistically attributing them to demographic characteristics rather than more complex legacies of training and prior learning. The current study analysed reported sex-related behavioural differences in ridden and non-ridden horses using data from responses to the pilot study of the Equine Behaviour Assessment and Research Questionnaire (E-BARQ) survey. Respondents (n = 1233) reported on the behaviour of their horse using a 151-item questionnaire. Data were searched for responses relating to mares and geldings, and 110 traits with the greatest percentage difference scores between mares and geldings were selected were tested for univariate significance at p < 0.2. Multivariable modelling of the effect of sex (mare or gelding) on remaining traits was assessed by ordinal logistic regression, using a cumulative proportional log odds model. Results revealed mares were significantly more likely to move away when being caught compared to geldings (p = 0.003). Geldings were significantly more likely to chew on lead ropes when tied (p = 0.003) and to chew on rugs (p = 0.024). However, despite sex-related differences in these non-ridden behaviours, there was no evidence of any significant sex-related differences in the behaviours of the horses when ridden. This finding suggests that ridden horse behaviour is not sexually dimorphic or that particular horse sports variously favour one sex over another.
Highlights
Horses are a source of companionship, leisure activities and sport for humans, and their temperament and behaviour directly contribute to their interactions with humans and conspecifics training, breeding and riding
Analysis of the 11 behavioural traits found mares to be significantly more likely to move away when being caught (p = 0.0032), and geldings to be more likely to chew on lead rope when being tied (p = 0.0032), and to chew rugs (p = 0.024506)
Avoidance behaviour in mares may be an aspect of the female equid ethogram, while chewing leads and rugs may be consistent with the male equid ethogram proclivity toward oral behaviours as described later
Summary
Horses are a source of companionship, leisure activities and sport for humans, and their temperament and behaviour directly contribute to their interactions with humans and conspecifics training, breeding and riding. Horses have contributed significantly to human history, initially serving as a source of food, followed by use for transportation, war and agricultural purposes [1,2,3]. In the leisure horse world and more in the non-professional equestrian domain, bias against mares is thought to reflect their perceived unreliability [1,2]. Because these preferences are largely anecdotal, further research is warranted in this domain
