Topic:Behavior
Equine behavior encompasses the study of horses' actions, reactions, and interactions within their environment and with other living beings. It includes the examination of innate behaviors, such as grazing and herd dynamics, as well as learned behaviors influenced by training and human interaction. Understanding equine behavior is essential for improving horse welfare, training methods, and management practices. This topic covers a range of behaviors, from social structures and communication to stress responses and problem behaviors. This page compiles peer-reviewed research studies and scholarly articles that explore the various aspects of equine behavior, including factors that influence it and its implications for horse management and welfare.
The tipping point: Exploring the influence of rider presence and posture on gait parameters in horses working in mounted equine-assisted services. Horses involved in equine-assisted services (EAS) support the psychological and physiological health of individuals through mounted activities; however, limited research exists on how these sessions affect the horse's movement. Objective: This study aimed to investigate the influence of rider presence and posture on horses' gait parameters in EAS settings. Methods: Horses (n = 22) were observed during walk and trot, both with and without a mounted rider, in four EAS centers in the United States. Distal limb-mounted inertial measurement units collected peak ground reaction force (pGRF), stride ...
Intrinsic characteristics of donkeys that affect drug treatment. Donkeys have contributed to the development and livelihoods of humans for almost 7,000 years. They have been used for traction and transportation, kept as pets, utilized in animal-assisted therapies, or farmed as food-producing animals. Over the past two decades, significant progress has been made in bridging the knowledge gap in veterinary medicine between donkeys and horses. Veterinary practitioners are now more aware that donkeys have important behavioral, anatomical, and physiological characteristics that distinguish them from horses. These peculiarities should be considered when treating ...

Technologies for equine welfare and performance monitoring under field conditions – Where do we stand? The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex adaptations. To monitor and determine equine welfare, an approach that focuses on the quantitative monitoring of both physiological and psychological parameters to determine and understand the impact of equestrian sports on horses is essential. Existing and emer...
Sexual arousal intensity modulates copulatory behavior and semen quality in Arabian stallions: Effects of age, origin, and collection method. Stallion sexual behavior during semen collection can be influenced by multiple factors, yet the role of sexual arousal intensity remains underexplored. Understanding how arousal modulates behavioral and physiological reproductive traits is essential for improving artificial insemination (AI) efficiency and semen quality. This study aimed to evaluate the effects of sexual arousal intensity, age, origin, and semen collection method on stallion sexual behavior and the quality of fresh and frozen semen. Unassigned: Thirteen Arabian stallions (7 Tunisian, 6 foreign parentage) aged 6-20 years (total...
Youth horse-related injuries (2014-2024): a scoping review of epidemiological and disciplinary insights. Although horse riding is hazardous and injuries are common, young riders regularly engage in horse-related activities. To our knowledge, there have been no syntheses on youth horse-related injuries published during the past decade that employ a multi- and interdisciplinary research agenda (M-IDR) and that incorporate both quantitative and qualitative methods. Therefore, this scoping review aimed to (1) review studies on horse-related injuries among children and adolescents and (2) identify methodological and paradigmatic trends according to M-IDR. Using the Preferred Reporting Items for System...

Hippotherapy in the Treatment of CMD and Bruxism in Dentistry. Dysfunctions and disorders of the craniomandibular system are accompanied by pathophysiological changes of muscle groups in the throat/neck and facial area, e.g., pain in the jaw and muscles of mastication and disturbance of occlusion, leading to teeth injury (loss of dental hard tissue, fractures/sensibility disorders, etc.). For muscular dysfunctions, even in the context of psychosomatic disorders and chronic stress, hippotherapy is particularly suitable, since it helps actively to relieve muscle tensions. In the current project we combined hippotherapy with progressive muscle relaxation (PM...
Cortisol and heart rate response of mares during the in-hand breeding procedure with and without restraint. In-hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objective: (1) To investigate whether the mares show increased stress responses during in-hand breeding using (a) a lip twitch and (b) hobbles. (2) To evaluate if the use of restraint methods influences the mare's expression of oestrous behaviour. Methods: Intra-individual cross-over design. Methods: Six Franches-Montagnes stallions and 10 warmblood mares were used in these experim...
Selection at the GSDMC locus in horses and its implications for human mobility. Horsepower revolutionized human history through enhanced mobility, transport, and warfare. However, the suite of biological traits that reshaped horses during domestication remains unclear. We scanned an extensive horse genome time series for selection signatures at 266 markers associated with key traits. We detected a signature of positive selection at -known to be a modulator of behavior in mice-occurring ~5000 years ago (ya), suggesting that taming was one of the earliest steps toward domestication of horses. Intensive selection at began ~4750 ya with the domestication bottleneck, leading ...
Are Equine Assisted Interactions (EAI) a Dark Horse Bet? A Systematic Review on Measuring the Psychological and Physiological Effects of EAI on PTSD, Anxiety and/or Mood Disorders. Background: Conventional forms of trauma-focused psychological interventions seem to be less effective in military veterans with post-traumatic stress disorder (PTSD). Equine Assisted Interventions (EAI) have become increasingly popular as an additional treatment, resulting in increasing research on the effects of EAI. However, no systematic review on the effects of EAI has focused on PTSD, anxiety and/or mood disorders and whether the effects are reflected in psychological and physiological measures. This systematic review investigated the treatment effects, study design, population, interven...
Optimizing equine standing sedation: continuous infusion of detomidine and butorphanol enhances stability but prolongs ataxia. This study aimed to compare the sedation quality and cardiorespiratory and behavioral effects of detomidine administered intravenously, either in intermittent boluses or as a continuous rate infusion, with butorphanol in horses pre-medicated with acepromazine for odontoplasty procedures. Unassigned: A prospective clinical study was conducted with fifteen adult horses randomly assigned to two groups: Bolus group (BG, = 7) and Infusion group (IG, = 8). Both groups received acepromazine premedication, followed by detomidine administration (bolus or infusion). Butorphanol was administered either...
Equine Pituitary Pars Intermedia Dysfunction. Pituitary pars intermedia dysfunction (PPID) is a common, slowly progressive, neurodegenerative disorder of the older horse. Oxidative damage to the hypothalamic periventricular neurons results in loss of dopaminergic inhibition of the pars intermedia region of the pituitary gland. Consequently, there is increased production of the pro-opiomelanocortin (POMC)-derived hormones normally produced by this region, as well as initial melanocyte hypertrophy and hyperplasia, followed by adenomatous change. Clinical signs that are highly suggestive of the disease are generalised and regional hypertrich...
Using Functional Near-Infrared Spectroscopy to Elucidate Neurophysiological Mechanism of Action of Equine-Assisted Services: Proof-of-Concept Study. Equine-assisted services (EAS) are used for civilian and military trauma survivors to reduce depression and posttraumatic stress symptoms. While early scientific evidence supports the benefits of EAS, the neurophysiological mechanisms underlying these benefits are unknown. The specific aims of this exploratory study were to determine (1) whether functional near-infrared spectroscopy (fNIRS) neuroimaging can be used to explore neural responses of EAS veteran participants and (2) the correlation between neural responses and psychological outcomes of the participants interacting with equines. Fif...

Horse vision through two lenses: Tinbergen’s Four Questions and the Five Domains. To improve human-horse interactions and reduce the risk of injury, it is essential to adopt an equi-centric perspective that prioritizes how horses perceive their environment. This review focuses on the equine visual system, both because it is the most studied of the horse's senses and because misunderstandings about how horses see can lead to unsafe or unsustainable handling. By applying two complementary frameworks, namely Tinbergen's Four Questions and the Five Domains model, we examine equine vision from both a biological and a welfare-oriented perspective. We explore the anatomical and fu...
Do stereotypies help or harm? Exploring the link between cortisol level and abnormal behaviours in animals: a review. Stereotypical behaviours in animals, often linked to stress, are repetitive actions that may lack a clear purpose. This review examines the relationship between cortisol levels, a key stress hormone, and stereotypic behaviour across various animal species, including zoo mammals, horses, and dogs. A total of 99 studies were analysed to understand whether elevated cortisol levels are associated with stereotypies. While many studies report a positive correlation between cortisol and stereotypical behaviour, more detailed research suggests that these behaviours may also serve as coping mechanisms,...
The Use of Sound Recorders to Remotely Measure Grass Intake Behaviour in Horses. Visual observation to record grass intake is time-consuming and labour-intensive. Technological methods, such as activity monitors, have been used but only record head position. This study aimed to evaluate sound recorders attached to headcollars to acoustically measure grass intake behaviour in horses as a low-cost alternative method. Pilot Study 1 assessed 6 × 11 min periods comparing bites/min and chews/min between video footage (VD) and sound recorders (SR). Grazing was identified audibly (SR) and visually through soundwave pattern software (SR). Chew rates (SR: 47 ± 5 chews/min, VD: 43 ...
A Qualitative Exploration of the Lived Experiences and Perspectives of Equine-Assisted Services Practitioners in the UK and Ireland. Equine-Assisted Services (EAS), which incorporate horses in a variety of ways in an effort to improve human wellbeing, have grown in popularity in recent years. Although much research has been conducted regarding the benefits that horses may provide for human health and wellbeing, little attention has been paid to practitioners' experiences and perspectives of the field, despite the fact they are uniquely positioned to advance our understanding of this area. This study aimed to explore practitioners' lived experiences of EAS, focusing on the benefits they observed, possible underlying mechanis...

Methods: Cross-sectional survey. Methods: The 40 question online international survey included a convenience sample of horse owners or caretakers with horses over 4 years old kept in the same individual stalls for at least the l...
“But my horse is well cared for”: A qualitative exploration of cognitive dissonance and enculturation in equestrian attitudes toward performance horses and their welfare. There is concern amongst the public, equestrians, animal welfare organisations, and horse-sport governing bodies regarding the welfare of performance horses, but equestrian culture appears slow to change. The present study seeks to increase our understanding of human factors underlying the persistence of welfare-compromising management and training practices within the performance horse world. Individual, semi-structured interviews focused on equestrians' attitudes were conducted with 22 equestrians from classical equestrian disciplines in the US, Canada, and the UK. Interview transcripts were...
Horse Activity Participants’ Perceptions About Practices Undertaken at Activity Venues, and Horse Welfare and Wellbeing. Participation in horse-related activities frequently involves relocating horses from the home stable to an activity venue, which might require local, regional, or international travel. In these circumstances, horses are exposed to unfamiliar surroundings and experience changes to their daily routines, which could have negative welfare impacts. An online survey was conducted in 2021 to ask experienced horse sector participants about the horse management practices that they perceived worked well and provided for positive horse welfare when undertaken at venues. Qualitative analysis identified fo...
Horse owners seeking online health information: a mixed-methods study. Many people seek health-related information online, not only for themselves but also on behalf of others who cannot articulate their symptoms. This proxy information-seeking behavior is particularly relevant for animal owners, who must interpret their animals' symptoms without direct verbal feedback. While online health information-seeking in the context of one's own health is well-studied, the specific challenges of searching by proxy, especially for animal health information, remain largely unexplored. Unassigned: This study aimed to determine the specific information needs and search behavi...
