	Title	Study of the behaviour, digestive efficiency and gut transit times of crib-biting horses			Type	Journal Article
	Year	2001	Publication	The Veterinary record	Abbreviated Journal	Vet. Rec.
	Volume	148	Issue	19	Pages	592-596
	Keywords	Animals; Behavior, Animal/physiology; Case-Control Studies; Digestion; Gastrointestinal Motility/drug effects; Horse Diseases/physiopathology; Horses/physiology/psychology; Male; Stereotyped Behavior/physiology; Sulfapyridine/blood; Sulfasalazine/diagnostic use/pharmacology
	Abstract	The spontaneous behaviour and the apparent digestibility of dry matter and fibre and transit times of digesta were compared in four normal horses and four crib-biters. A technique was developed for measuring total gut transit times (TGTT) by using single-stool analysis of the passage of radio-opaque polyethylene markers. Longer TGTT were recorded in the crib-biters than in the normal horses but the orocaecal transit times did not differ. The crib-biters rested less than the normal horses.

	Title	The prevalence of abnormal behaviours in dressage, eventing and endurance horses in relation to stabling			Type	Journal Article
	Year	1995	Publication	The Veterinary record	Abbreviated Journal	Vet. Rec.
	Volume	137	Issue	2	Pages	36-37
	Keywords	Animal Husbandry/methods; Animals; Behavior, Animal; Horse Diseases/psychology; Horses; Physical Conditioning, Animal; Prevalence; Questionnaires; *Stereotyped Behavior
	Abstract	The behaviour of horses competing in different disciplines was studied and the relationship between the time they spent out of the stable and the prevalence of abnormal behaviour was examined. The owners of dressage, eventing and endurance horses were sent a questionnaire and a total of 1101 responses were received, giving data on 1750 horses. The behaviours studied were wood-chewing, weaving, crib-biting/wind-sucking and box-walking. The reported percentage prevalences of abnormal behaviour for the dressage, eventing and endurance horses were 32.5, 30.8 and 19.5, respectively. The relationship between the time spent in the stable and the prevalence of abnormal behaviour was examined by chi 2 tests which showed that there were significant linear trends for the eventing group (P < 0.001) and the dressage group (P < 0.05). It is concluded that the time a horse spends out of the stable is related to the discipline for which it is being trained and in dressage and eventing horses the time spent in a stable is correlated with an increased risk of abnormal behaviour.

	Title	The advent of equitation science			Type	Journal Article
	Year	2006	Publication	The Veterinary Journal	Abbreviated Journal	Vet J
	Volume	174	Issue	3	Pages	492-500
	Keywords
	Abstract	The lengthy association of humans with horses has established traditional equestrian techniques that have served military and transport needs well. Although effective, these techniques have by-passed the research findings of modern psychologists, who developed the fundamentals of learning theory. That said, the pools of equestrian debate are far from stagnant. The latest wave of horse whisperers has offered some refinements and some novel interpretations of the motivation of horses undergoing training. Additionally, the Federation Equestre Internationale (FEI) has introduced the concept of the 'happy equine athlete' and, in the light of the hyperflexion (Rollkur) debate, recently examined the possible effects of some novel dressage modalities on equine 'happiness'. However, many still question the welfare of the ridden horse since it is largely trained using negative reinforcement, has to respond to pressure-based signals and is seldom asked to work for positive rewards. Science holds tremendous promise for removing emotiveness from the horse-riding welfare debate by establishing how much rein tension is too much; how much contact is neutral; how contact can be measured; how discomfort can be measured; how pain can be measured; and how learned helplessness manifests in horses. These are some of the topics addressed by equitation science, an emerging discipline that combines learning theory, physics and ethology to examine the salience and efficacy of horse-training techniques.

	Title	The horse–human dyad: Can we align horse training and handling activities with the equid social ethogram?			Type	Journal Article
	Year	2009	Publication	The Veterinary Journal	Abbreviated Journal	Special Issue: Equitation Science
	Volume	181	Issue	1	Pages	12-18
	Keywords	Horse training; Social inter- and intra-specific communication; Learning; Counter–predator behaviour
	Abstract	This article examines the recently completed equid ethogram and shows how analogues of social interactions between horses may occur in various human–horse interactions. It discusses how some specific horse–horse interactions have a corresponding horse–human interaction – some of which may be directly beneficial for the horse while others may be unusual or even abnormal. It also shows how correspondent behaviours sometimes become inappropriate because of their duration, consistency or context. One analogue is unlikely to hold true for all horse–human contexts, so when applying any model from horse–horse interactions to human–horse interactions, the limitations of the model may eclipse the intended outcome of the intervention. These limitations are especially likely when the horse is being ridden. Such analyses may help to determine the validity of extrapolating intra-specific interactions to the inter-specific setting, as is advocated by some popular horse-training methods, and highlight the subsequent limitations where humans play the role of the ‘alpha mare’ or leader in horse handling and training. This examination provides a constructive framework for further informed debate and empirical investigation of the critical features of successful intra-specific interactions.

	Title	Dominance and Leadership: Useful Concepts in Human-Horse Interactions?			Type	Journal Article
	Year	2017	Publication	Journal of Equine Veterinary Science	Abbreviated Journal	Proceedings of the 2017 Equine Science Symposium
	Volume	52	Issue		Pages	1-9
	Keywords	Horse; Social order; Dominance hierarchy; Aggression; Injury; Learning; Training
	Abstract	Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have been reported to be higher than in their feral counterparts but can often be attributed to suboptimal management. Horse owners often express concerns about the risk of injuries occurring in group-kept horses, but these concerns have not been substantiated by empirical investigations. What has not yet been sufficiently addressed are human safety aspects related to approaching and handling group-kept horses. Given horse's natural tendency to synchronize activity to promote group cohesion, questions remain about how group dynamics influence human-horse interactions. Group dynamics influence a variety of management scenarios, ranging from taking a horse out of its social group to the prospect of humans mimicking the horse's social system by taking a putative leadership role and seeking after an alpha position in the dominance hierarchy to achieve compliance. Yet, there is considerable debate about whether the roles horses attain in their social group are of any relevance in their reactions to humans. This article reviews the empirical data on social dynamics in horses, focusing on dominance and leadership theories and the merits of incorporating those concepts into the human-horse context. This will provide a constructive framework for informed debate and valuable guidance for owners managing group-kept horses and for optimizing human-horse interactions.

	Title	Over-flexing the horse's neck: A modern equestrian obsession?			Type	Journal Article
	Year	2010	Publication	Journal of Veterinary Behavior: Clinical Applications and Research	Abbreviated Journal	Journal of Veterinary Behavior: Clinical Applications and Research
	Volume	5	Issue	4	Pages	180-186
	Keywords
	Abstract	We used an opportunistic review of photographs of different adult and juvenile horses walking, trotting, and cantering (n = 828) to compare the angle of the nasal plane relative to vertical in feral and domestic horses at liberty (n = 450) with ridden horses advertised in a popular Australian horse magazine (n = 378). We assumed that horses in advertisements were shown at, what was perceived by the vendors to be, their best. Of the ridden horses, 68% had their nasal plane behind the vertical. The mean angle of the unridden horses at walk, trot, and canter (30.7 ± 11.5; 27.3 ± 12.0; 25.5 ± 11.0) was significantly greater than those of the ridden horses (1.4 ± 14.1; ?5.1 ± ?11.1; 3.1 ± 15.4, P < 0.001). Surprisingly, unridden domestic horses showed greater angles than feral horses or domestic horses at liberty. We compared adult and juvenile horses in all 3 gaits and found no significant difference. Taken together, these findings demonstrate that the longitudinal neck flexion of the degree desirable by popular opinion in ridden horses is not a common feature of unridden horses moving naturally. Moreover, they suggest that advertised horses in our series are generally being ridden at odds with their natural carriage and contrary to the international rules of dressage (as published by the International Equestrian Federation). These findings are discussed against the backdrop of the established doctrine, which states that carrying a rider necessitates changes in longitudinal flexion, and in the context of the current debate around hyperflexion.

	Title	Punishment in horse-training and the concept of ethical equitation			Type	Journal Article
	Year	2009	Publication	Journal of Veterinary Behavior	Abbreviated Journal	J. Vet. Behav.
	Volume	4	Issue	5	Pages	193-197
	Keywords	conditioning; welfare; ethical equitation; horse; punishment; training
	Abstract	By definition, punishment makes a response less likely in the future. Because horses are largely trained by negative reinforcement, they are susceptible to inadvertent punishment. Delays in the release of pressure can make desirable responses less likely and thus punish them. This study examines the correct use of negative reinforcement and identifies a continuum between poorly timed negative reinforcement and punishment. It explores some of the problems of non-contingent punishment and the prospect of learned helplessness and experimental neurosis. It concludes by introducing the concept of ethical equitation.

	Title	Prevention of crib-biting: a review			Type	Journal Article
	Year	1998	Publication	Equine veterinary journal. Supplement	Abbreviated Journal	Equine Vet J Suppl
	Volume		Issue	27	Pages	35-38
	Keywords	Animals; Behavior, Animal; Horse Diseases/prevention & control/psychology; Horses; *Stereotyped Behavior
	Abstract	Crib-biting is a common oral stereotype. Because of perceived deleterious effects on the health and appearance of subjects the prevention of crib-biting is regularly attempted. The resourcefulness of horses in satisfying their motivation to perform this behaviour often frustrates owners' efforts at prevention. This paper reviews the efficacy and observable consequences of attempting to prevent crib-biting by a variety of methods. These include attempts to prevent the grasping of objects, to interfere with air-engulfing and to introduce punishment for grasping and neck-flexion. Other approaches include the use of surgery, acupuncture, pharmaceuticals, operant feeding and environmental enrichment. A remedy that is effective for every crib-biter remains elusive. We conclude that, rather than concentrating on remedial prevention, further research should be directed at establishing why horses crib-bite and how the emergence of crib-biting can be avoided.

	Title	The effect of short-term prevention on the subsequent rate of crib-biting in thoroughbred horses			Type	Journal Article
	Year	1998	Publication	Equine veterinary journal. Supplement	Abbreviated Journal	Equine Vet J Suppl
	Volume		Issue	27	Pages	30-34
	Keywords	Analysis of Variance; Animals; Behavior, Animal; Horse Diseases/prevention & control/psychology; Horses; Male; Recurrence; *Stereotyped Behavior; Videotape Recording
	Abstract	The results of an experimental study of the motivational consequences of short-term prevention of crib-biting are reported here. Eight test horses wore a cribbing collar for 24 h. This was effective in preventing crib-biting in 6 subjects. Using analysis of co-variance that accounted for baseline differences in crib-biting rate, test horses showed significantly more crib-biting than control horses on the first day after prevention (P < 0.05). There was also a highly significant increase in the crib-biting rate of test horses on the first day after prevention in comparison with their baseline rate (P < 0.01). This defines the increase as a post inhibitory rebound. An increase in the novelty of the cribbing bar and an increase in feeding motivation during the period of prevention are rejected as explanations of the rebound in this study. Instead, it is suggested that the rebound reflected a rise in internal motivation to crib-bite during the period of prevention. Behaviours that exhibit this pattern of motivation are generally considered functional; and it has been argued that their prevention may compromise welfare.
