Equine welfare encompasses the physical and psychological well-being of horses, focusing on their health, comfort, and overall quality of life. This area of study addresses various aspects, including nutrition, housing, behavior, and management practices, aiming to ensure that horses are kept in environments that meet their physiological and behavioral needs. Research in equine welfare examines factors such as stress indicators, pain assessment, and the impact of human interactions on horse behavior and health. This page compiles peer-reviewed research studies and scholarly articles that explore the assessment, improvement, and implications of welfare practices in equine management.
Tripon MA, Manolăchescu D, Papuc I, Daradics Z, Crecan CM.Emotional contagion between horses and humans is a key aspect of their interaction, influencing welfare, training, and therapy, yet current methods for measuring this phenomenon lack standardization and consistency. Objective: The aim of this study was to verify what methods are used to assess emotional contagion in horse-human interactions, and what outcomes have been reported. Methods: A systematic search of Google Scholar, Web of Science, Scopus, PubMed, and Science Direct was conducted up to March 2024. Peer-reviewed studies assessing emotional transfer through behavioral and/or physiologi...
Briefer-Freymond S, Dalla Costa E, Jolivald A, Bruckmaier RM, Atallah E, Giorgia Riva M, Ijichi C.Personality affects both experience and expression of pain and the welfare impact of castration on horses is poorly understood. Therefore, the current study observed 19 horses to determine: the welfare impact of standard castration on horses; whether individuals consistently vary in their behavioural and emotional responses to pain; the influence of personality on behavioural and physiological responses to pain; whether Horse Grimace Scale (HGS) indicates how individuals feel about painful experiences. Eye temperature (IRT), salivary cortisol, HGS and a pain ethogram were measured at intervals...
Tobin G, Cullen S, Dunne A, Warrington G, Pugh J, McGoldrick A, Nolan C, Losty C.Stable staff and trainers are essential to racing yards and horse welfare, yet limited research focuses on this vital workforce that the thoroughbred industry heavily relies on. This systematic narrative review synthesizes existing literature on the occupational health and well-being of stable staff and trainers in the thoroughbred horse racing industry. Methods: A systematic narrative review was conducted across PubMed, Google Scholar, and Scopus using relevant keywords. Manuscripts reporting occupational or mental health data on stable staff and/or trainers and had the full-text available we...
James C, Sheahan J, Arthur P.Thoroughbred race performance is influenced by genetics, training, recovery, and management, but decisions about race readiness are often subjective and lack validated physiological markers. This study evaluated thiol-oxidised albumin, a blood-based indicator of oxidative stress, as a potential biomarker of pre-race fitness in Australian Thoroughbreds. Seventy-five clinically healthy racehorses from seven stables were monitored across 216 competitive events (150 races, 66 trials). Blood samples were collected from the jugular at baseline, 48 h pre-race, and for each day up to 8 days post-race ...
Jandová V, Huber N, AlMheiri FG, Bábor K, Trachsel DS.Stress represents a serious health and welfare concern; however, its objective assessment remains difficult. The equine gastric ulcer syndrome (EGUS) and orthopedic diseases that cause pain are among stress associated diseases in equine medicine. The leukocyte coping capacity (LCC) quantifies oxygen radical generation of neutrophil granulocytes which is altered under stress. Therefore, LCC could be a novel biomarker for stress in horses and we hypothesized that horses with stress associated diseases would have lower LCC values in comparison to horses without these diseases. Methods: In this ob...
Curry O, Everett A, Pearson G, Dwyer C, Duncan J.Despite the availability of several equine pain assessment tools, their use in equine veterinary practice appears limited compared to small animal practice. This study explores potential barriers to equine pain assessment, as reported by staff at a single UK equine teaching hospital. Methods: Nine hospital staff members were interviewed using semi-structured interviews. Key themes were identified through reflexive thematic analysis. Results: Participants acknowledged the importance of pain assessment, yet highlighted limitations in current methods and their inconsistent use. Key challenges inc...
Manolăchescu D, Tripon M, Crecan C, Tătaru M, Papuc I.Emotional contagion in human-horse interactions has been widely studied; however, the role of body language in stress transfer remains insufficiently explored. Unassigned: This study examines whether human emotional states, particularly stress and anxiety, influence horses and whether the transmission occurs primarily through body language. Unassigned: A repeated-measures within-subjects design was used. The order of interaction styles was randomized across subjects during 33 HCIs. Participants were categorized as high-anxiety (HA) or low-anxiety (LA) based on State Anxiety Scale scores and he...
Bolesławska-Szubartowska J, Kucharczuk M, Skrabska A, Zbysław A, Adamowicz J, Alszko A, Domagalska-Stomska K, Durska M, Dziekcierów A....Pain after giving birth is commonly observed in horses, yet there has not been a specific tool developed for assessing this pain in postpartum mares. The goal was to adapt existing equine pain scales and to preliminarily validate a practical pain scale for use by veterinarians and caregivers after foaling. Methods: The pain scale was developed by adapting items from other pain scales, including established orthopedic and colic equine pain scales, and incorporating caregiver feedback. The final scale includes eight areas for assessing pain: behavior, facial expressions, vital signs, udder exami...
Kogstad N, Christiansen SE, Ulberg R, Fiskum C.The integration of horses into psychotherapy has gained popularity over recent decades, offering unique therapeutic opportunities that may enhance emotional healing, empathy, and relational trust. This study investigates the perspectives of experienced psychotherapists on why they incorporate horses into their therapeutic practices. In-depth interviews were conducted with ten clinicians (eight female, two male) from diverse theoretical orientations. The data, which were analyzed using reflexive thematic analysis, revealed four key themes: "Supporting presence and getting to the heart of things...
Equine cognition is relevant to the many roles that horses serve in society, such as leisure riding, competitions, or even animal-assisted therapy. Equine cognitive abilities have been explored in recent years. However, gaining an overview of horse cognition is challenging due to the broad range of abilities studied and the diverse methodologies employed. In addition, the subjects of existing equine cognition studies vary greatly in contextual factors such as their breed, age, sex, and management conditions - each of which may influence test performance in the following cognitive categories: D...
Sivagurunathan R, Senathirajah ARBS, Sivagurunathan L, Arokiasamy L, Qazi S, Haque R, Su Y.This study explores how equine-assisted leadership development (EALD) interventions activate experiential processes that reshape leaders' self-concept, relational schemas, and behaviors. A conceptual model is proposed to explain how non-verbal interaction with horses catalyzes transformational learning. Unassigned: A qualitative exploratory design was employed to examine leaders' experiences over 12 months following reintegration into their workplaces. Eight leaders ( = 8) attended a 5-day EALD program, engaging in "join-up" exercises with horses. Data were analyzed through reflexive the...
McDonald S, Verheyen KLP, Chang YM, Allen SE.Race-related injuries in horse racing, especially those requiring extended recovery, are a welfare concern and threaten the sport's social licence. Previous studies predominantly report on fatalities; however, serious non-fatal musculoskeletal injuries often end horses' racing careers or have a high recurrence risk. No recent studies have described or quantified long-term injuries (LTIs) in racing Thoroughbreds, which is essential to inform targeted risk prevention strategies. Objective: To describe the types, frequencies and incidences of LTIs in British jump racing. Methods: Retrospective co...
Pilger F, Aurich C, Aurich JE.The early career start of racehorses, the pretraining of two-year-old Warmblood stallions for licensing, and individual housing of young horses increasingly raise animal welfare concerns. Objective: Assess pretraining practices and the opinion of trainers on housing of young horses, minimum age to commence training and pretraining injuries. Methods: Qualitative interviews with trainers of Warmblood stallions and Thoroughbred and Trotter racehorses (n = 10 each). Results: Pretraining of Thoroughbreds and Trotters began at 18 months, whereas licensing preparation of Warmblood stallions began at ...
Keller P, Vanwesenbeeck I, Hudders L, Decloedt A.To assess horse owners' behaviors and perceptions regarding communication about complementary and alternative veterinary medicine (CAVM) with their veterinarian. Unassigned: A cross-sectional online survey was combined with a qualitative study in the form of in-depth interviews with Flemish horse owners. Unassigned: The study included 1,532 fully completed survey responses and 26 interviews. Overall, horse owners showed high trust in the veterinarian and were satisfied with veterinarian-client communication. While 61.7% of participants indicated that they had already talked about CAVM with the...
Kawamura N, Sakamoto M, Hashimoto C, Ozeki Y, Machida K.Children with autism spectrum disorder (ASD) often experience challenges in social communication, behavioral regulation, and daily life adaptation. Equine-assisted activities and therapies (EAATs) have been implemented as complementary approaches to support psychosocial development. However, little is known about the experiences of parents in Japan whose children participate in EAATs. Unassigned: The study aims to qualitatively explore how parents in Japan perceive the psychosocial outcomes of EAATs for their children with ASD. By focusing on parental perspectives, this study seeks to clarify ...
Giannone C, Atallah E, Dalla Costa E, Benetti E, Santolini E, Tassinari P, Bovo M.Technology for monitoring behaviour and health of horses has evolved significantly, presenting new opportunities and challenges in equine management and healthcare. This scoping review consolidates recent findings on wearable sensors and non-contact technologies, discussing their benefits and limitations. Among these advancements, heart rate monitors stand out as a key point in equine monitoring. By tracking heart rate variability, devices help monitor cardiac autonomic regulation, optimise training regimens and allow early detection of cardiac issues, although accuracy can be compromised by i...
Badin L, Van Dendaele E, Bailly N.: Although equine-assisted interventions (EAI) are gaining growing attention, their scientific evaluation among individuals with Alzheimer's disease (AD) living in nursing homes remains limited. This study aimed to explore the lived experiences of an EAI program from the perspectives of the participants living with AD as well as their families and professional caregivers. : Thirty non-directive interviews were conducted between June and July 2024 across several nursing homes in the Centre-Val de Loire region (France). The interviews were recorded, transcribed, and analyzed using thematic analy...
d'Ingeo S, Siniscalchi M, Quaranta A, Cousillas H, Hausberger M.Current research on acoustic encoding of emotional content suggests that there are universal cues, allowing for decoding within and across taxa. This is particularly important for human-animal relationships, wherein domestic animals are supposed to be particularly efficient in decoding human emotions. Here we investigated whether the decoding of the emotional content in human voices shared universal acoustic properties, or whether it could be influenced by experience. Emotional human voices were presented to two populations of horses, in which behavioral, cardiac, and brain responses were meas...
Taylor DEF, Lancaster BE, Ellis AD.There are few 24 h time budgets for horses, especially for domesticated horses kept at pasture. Most time budgets utilise short-term scan sampling, which can miss behaviours. This study aimed to assess the seasonal variation in continuous behaviour of domesticated Icelandic horses at pasture during winter and spring in fair weather. Eight Icelandic horses (11.25 ± 9.19 years; 7 geldings, 1 stallion) were observed in a 26 acre field. Herd location and individual behaviour were continuously observed during 3 h periods amounting to 3 × 24 h in winter and late spring, compiled over 43 days (~21 ...
Purnama MTE, Fikri F, Çalışkan H, Wicaksono AP.Racehorses endure high physical demands, which often result in musculoskeletal pain, fatigue, and reduced performance. Although conventional therapies are effective, competition-related drug regulations restrict their use. Acupuncture, rooted in Traditional Chinese Veterinary Medicine, has gained interest as a non-pharmacological alternative for managing pain, enhancing recovery, and promoting overall welfare in equine athletes. This review aims to critically evaluate the current evidence on the efficacy of acupuncture in racehorses, focusing on musculoskeletal pain management, post-exercise r...
Warren P, Mc Crudden D, O'Reilly S, Mc Eleney C.Macroalgae have been used in supplements and feedstuffs for equines and other animals for many years. Health-related attributes of macroalgal bioactive compounds, including antioxidant, anti-inflammatory and anthelmintic effects, have been largely reported in non-equine species to date. Given the prevalence of resistance to antimicrobial and anthelmintic drugs, sourcing naturally occurring alternatives is of high priority in the current One Health strategy. Nutritionally, seaweed contains a broad range of macro and micro nutrients. These nutrients, combined with the bioactive compounds such as...
Schumacher A, Merle R, Stöckle S, Gehlen H.Polo is an equestrian sport with a long tradition, but to date there is little scientific data on health risks, particularly lameness. In an international online survey, 145 polo players (47.6% female, 52.4% male) with an average of 13.4 years of playing experience were questioned about lameness risks and influencing factors. The respondents reported a median of six horses, most frequently mares as their best-performing and healthiest animals. Horse age was significantly associated with the risk of lameness, increasing by approximately 19.5% per year (OR = 1.195; = 0.030) and differed dependi...
Training on deep sand is commonly employed in endurance horses, but its physiological adaptation remains poorly characterized. This study aimed to characterize locomotor adaptations during a 7 km controlled-speed canter on deep sand in eighteen endurance horses, to identify heart rate variability (HRV) components, and to investigate changes in hematological variables before and after exercise. Stride frequency (SF) and stride length (SL), HRV, and hematological profiles were recorded during exercise and recovery with a fitness tracker. Associations between maximum speed and locomotor parameter...
Losty C, Sreenivas S.Feminist sport researchers examine the unique experiences of female athletes as crucial in promoting women's sport participation and parity in opportunities (Lebel et al., 2021). Insight into the unique stressors encountered by female jockeys in Ireland (Irl) and the United Kingdom (UK) may provide sport scientists, practitioners and policy makers with a greater awareness of the specific supports they need (Losty & Sreenivas, 2023). Deeply personal and complex decisions for female athletes, such as starting a family, can be shaped by various professional performance factors. The impact of beco...
Klinck M, Lovett A, Sykes B.Equine gastric ulcer syndrome (EGUS) refers to mucosal gastric disease in horses, including equine squamous gastric disease (ESGD) and equine glandular gastric disease (EGGD), which present as two distinct disease entities differing in pathophysiology and approach to disease management. Both diseases are a source of pain in affected horses, partly explaining why EGUS continues to receive substantial attention in the equine medical, welfare and equitation research sectors. There is a complex interplay between EGUS and a variety of physical and psychological stressors. Horses with EGUS are often...
Braga C, Prazeres J, Borges J, Ribeiro G.To noninvasively characterize skin thickness and elasticity in healthy horses using B-mode ultrasound and shear wave elastography (SWE) and to verify whether there are differences between the skin of stabled and outdoor horses. Unassigned: 10 clinically healthy horses were enrolled in this study. Five animals were housed exclusively indoors (indoor group), and 5 had temporary or permanent access to an outdoor environment (outdoor group). All horses underwent bilateral ultrasonographic examination of 3 anatomical regions: neck, withers, and girth region caudal to the elbow. Skin thickness was a...
Dalla Costa E, Bovo M.Flowchart illustrating interdisciplinary collaboration in animal research. A horse symbolizes the focus, with pathways connecting physiology, behavior, and environment to decision-making and regulatory indications. Data analysis, system understanding, and data interpretation lead to feedback and warning. Visual elements include sun, clouds, a light bulb, gears, and a graph.
Wnuk E, Janicka W, Stachurska A, Owerczuk R, Łuszczyński J.Differences in the ranges and capacities of sensory modalities cause horses to perceive their surroundings differently than humans. To date, the horses' sense of smell has been studied mainly regarding social and reproductive behaviour. The role of olfaction in horse management and use also seems to be of utmost importance. The aim of this study was to determine the response to a scent of different intensities by horses of different sexes and types (warmblood horses vs ponies). The study involved 21 adult mares and geldings, of which 15 subjects learned how to complete the required task and we...
Musial F, Weiss T.Bit pressure and rein tension-induced mouth pain in horses have recently become a significant welfare concern, fueling debates within the equestrian community and beyond. Evidence indicates that bits can cause pain-related behaviors and even oral lesions. Although studying pressure-induced pain in animals is challenging, the similarities in the physiology of pain processing (nociception) across mammals suggest that it is reasonable to assume that pain perception in humans and horses is principally comparable. Therefore, we compared human pressure pain detection thresholds (PPDTs) to reported r...
Söderroos D, Stefánsdóttir GJ, Ragnarsson S, Gunnarsson V, Jansson A.Weight-carrying capacity is important in riding horses both for performance and welfare, yet there is no standardized method to estimate individual horses' weight-carrying capacity. This study investigated the correlation between the physiological response during a (i) standardized incremental exercise test (SET) on a treadmill and a (ii) ridden incremental weight-carrying exercise test (WET). Sixteen horses (15 ± 3 years) performed both tests, including four steps with increased speed or weight load, respectively. Body weight ratio (BWR) in the WET was 20%, 25%, 30%, and 35% in each st...
Pawluski J, Jego P, Henry S, Bruchet A, Palme R, Coste C, Hausberger M.The hypothalamic-pituitary-adrenal (HPA) axis response to chronic stress is far from straight forward, particularly with regards to animal welfare. There are reports of no effect as well as both decreases and increases in cortisol after chronic stressors. Therefore, the first aim of the present study was to determine how measures of compromised welfare, such as chronic pain and haematological anomalies, related to cortisol levels in domestic horses (Equus caballus). Domestic horses are an informative model to investigate the impact of chronic stress (due to environment, pain, work, housing con...
Henry S, Fureix C, Rowberry R, Bateson M, Hausberger M.This field study tested the hypothesis that domestic horses living under putatively challenging-to-welfare conditions (for example involving social, spatial, feeding constraints) would present signs of poor welfare and co-occurring pessimistic judgement biases. Our subjects were 34 horses who had been housed for over 3 years in either restricted riding school situations (e.g. kept in single boxes, with limited roughage, ridden by inexperienced riders; N = 25) or under more naturalistic conditions (e.g. access to free-range, kept in stable social groups, leisure riding; N = 9). The horses'...
Uldahl M, Clayton HM.Information is needed to guide sport administrators in formulating rules for equipment use in competitions. Objective: To seek associations between spurs, bits, nosebands and whips with injuries in horses during competitions in four equestrian sports. Methods: Cross sectional study. Methods: Post competition evaluations were performed in 3143 horse/rider combinations competing in Danish Equestrian Federation competitions in dressage, showjumping, eventing and endurance by trained evaluators who recorded the presence and type of spurs, bits, nosebands, and whips. Further evaluations recorded no...
Hausberger M, Gautier E, Biquand V, Lunel C, Jégo P.Stress at work, as shown by a number of human studies, may lead to a variety of negative and durable effects, such as impaired psychological functioning (anxiety, depression...). Horses share with humans this characteristic of working on a daily basis and are submitted then to work stressors related to physical constraints and/or more "psychological" conflicts, such as potential controversial orders from the riders or the requirement to suppress emotions. On another hand, horses may perform abnormal repetitive behaviour ("stereotypies") in response to adverse life conditions. In the present st...
Torcivia C, McDonnell S.In recent years, there has been a growing interest in and need for a comprehensive ethogram of discomfort behavior of horses, particularly for use in recognizing physical discomfort in domestically managed horses. A clear understanding of the physical discomfort behavior of horses among caretakers, trainers, and professional health care personnel is important to animal welfare and caretaker safety. This is particularly relevant to pain management for hospitalized equine patients. Various pain scale rubrics have been published, typically incorporating only a few classically cited pain behaviors...
McGreevy PD.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 Fédération Equestre Internationale (FEI) has introduced the concept of t...
Hewson CJ, Dohoo IR, Lemke KA, Barkema HW.Anecdotal evidence suggests that many veterinarians may not use analgesics in livestock for routine surgical procedures or painful disease states. To investigate this, we conducted a national mail survey of a random sample of 1431 Canadian veterinarians (response rate, 50.1%). Questions primarily concerned veterinarians' analgesic usage for common surgeries and medical conditions in beef and dairy cattle, pigs, and horses, and attitudes toward pain management. More than 90% of veterinarians used analgesic drugs for equine surgeries, for cesarean section in sows and cows, and for bovine claw am...
Harvey AM, Beausoleil NJ, Ramp D, Mellor DJ.Knowledge of the welfare status of wild animals is vital for informing debates about the ways in which we interact with wild animals and their habitats. Currently, there is no published information about how to scientifically assess the welfare of free-roaming wild animals during their normal day-to-day lives. Using free-roaming horses as an example, we describe a ten-stage protocol for systematically and scientifically assessing the welfare of individual non-captive wild animals. The protocol starts by emphasising the importance of readers having an understanding of animal welfare in a conser...
Mach N, Ruet A, Clark A, Bars-Cortina D, Ramayo-Caldas Y, Crisci E, Pennarun S, Dhorne-Pollet S, Foury A, Moisan MP, Lansade L.We simultaneously measured the fecal microbiota and multiple environmental and host-related variables in a cohort of 185 healthy horses reared in similar conditions during a period of eight months. The pattern of rare bacteria varied from host to host and was largely different between two time points. Among a suite of variables examined, equitation factors were highly associated with the gut microbiota variability, evoking a relationship between gut microbiota and high levels of physical and mental stressors. Behavioral indicators that pointed toward a compromised welfare state (e.g. stereotyp...
Dugdale AH, Curtis GC, Cripps P, Harris PA, Argo CM.Increased prevalence of obesity among UK horses and ponies demands evidence-based advice to promote weight loss. Objective: Restriction of dry matter intake (DMI) to 1% of body mass (BM, 67% [corrected] of predicted maintenance digestible energy [DE] requirements) would promote weight loss without compromise to health. Methods: Five mature (mean ± s.e. 10 ± 2 years), overweight/obese pony mares (BM, 257 ± 20 kg: body condition score [BCS] 6.8/9 ± 0.5) were studied over 12 weeks. Animals were individually housed. Daily provision of a chaff-based, complete diet (measured DE, 8.5 MJ/kg DM) wa...
Dalla Costa E, Pascuzzo R, Leach MC, Dai F, Lebelt D, Vantini S, Minero M.Pain recognition is fundamental for safeguarding animal welfare. Facial expressions have been investigated in several species and grimace scales have been developed as pain assessment tool in many species including horses (HGS) and mice (MGS). This study is intended to progress the validation of grimace scales, by proposing a statistical approach to identify a classifier that can estimate the pain status of the animal based on Facial Action Units (FAUs) included in HGS and MGS. To achieve this aim, through a validity study, the relation between FAUs included in HGS and MGS and the real pain co...
Parkin TD, Clegg PD, French NP, Proudman CJ, Riggs CM, Singer ER, Webbon PM, Morgan KL.Considerable variation in the rates of equine fatality at different racecourses draws attention to probable risk factors at the level of course or race that might be partly responsible. Distal limb fractures are the most common cause of equine fatality on UK racecourses and identification of risk factors for such injuries and subsequent implementation of intervention strategies could significantly reduce the total number of racecourse fatalities. Objective: To identify race- and course-level risk factors for fatal distal limb fracture in Thoroughbreds on UK racecourses. Methods: A case-control...
Yarnell K, Hall C, Billett E.Animal management often involves procedures that, while unlikely to cause physical pain, still cause aversive responses. The domestic horse (Equus caballus) regularly has excessive hair clipped off to facilitate its use as a riding/driving animal and this procedure causes adverse behavioral responses in some animals. The aim of this study was to compare behavioral and physiological measures to assess the aversive effect of this procedure. Ten horses were selected on the basis of being either compliant (C: n=5) or non-compliant (NC: n=5) during this procedure. The horses were subjected to a sha...
Bachmann I, Audigé L, Staﾬher M.Studies on the prevalence of behavioural disorders in horses and on associated risk factors have revealed inconsistent results. There are many studies on the neuropharmacological, surgical or mechanical therapy of stereotypies, but little is known about their causation. Objective: To explore risk factors associated with the occurrence of behavioural disorders in horses. Methods: A sample of horse owners, selected randomly and representative for Switzerland, was contacted in a postal survey. Answers were provided for 622 stables (response rate 35.2%). Individual data of 2,341 horses were examin...
Ruet A, Lemarchand J, Parias C, Mach N, Moisan MP, Foury A, Briant C, Lansade L.Horses are mainly housed in individual boxes. This housing system is reported to be highly detrimental with regard to welfare and could trigger the expression of four behavioural indicators of a compromised welfare state: stereotypies, aggressiveness toward humans, unresponsiveness to the environment, and stress-related behaviours. The aim of this study was to identify housing and management factors that could alleviate the detrimental effects of individual boxes on welfare. A total of 187 horses were observed over 50 days by scan sampling. The impact of 12 factors was investigated on the expr...
Back pain is the cause of bad welfare in humans and animals. Although vertebral problems are regularly reported on riding horses, these problems are not always identified nor noticed enough to prevent these horses to be used for work. Results: Nineteen horses from two riding centres were submitted to chiropractic examinations performed by an experienced chiropractor and both horses' and riders' postures were observed during a riding lesson. The results show that 74% of horses were severely affected by vertebral problems, while only 26% were mildly or not affected. The degree of vertebral probl...
Padalino B, Hall E, Raidal S, Celi P, Knight P, Jeffcott L, Muscatello G.Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study analysed reports of transport related health problems identified by drivers and horse owners for 180 journeys of an Australian horse transport company transporting horses between Perth and Sydney (~4000 km) in 2013-2015. Records showed that 97.2% (1604/1650) of the horses arrived at their destination with no...
Hernández-Avalos I, Mota-Rojas D, Mendoza-Flores JE, Casas-Alvarado A, Flores-Padilla K, Miranda-Cortes AE, Torres-Bernal F, Gómez-Prado J....Pain and anxiety are two of the most important concerns in clinical veterinary medicine because they arise as consequences of multiple factors that can severely affect animal welfare. The aim of the present review was to provide a description and interpretation of the physiological and behavioral alterations associated with pain and anxiety in equines. To this end, we conducted an extensive review of diverse sources on the topic. The article begins by describing the neurophysiological pathway of pain, followed by a discussion of the importance of the limbic system in responses to pain and anxi...
Upjohn MM, Pfeiffer DU, Verheyen KL.There are an estimated 112 million Equidae (horses, donkeys, mules) in the developing world, providing essential resources for their owners' livelihoods and well-being. The impoverished situation of their owners and the often harsh conditions in which they work mean that the animals' welfare is a cause for concern. A number of equine non-governmental organisations (NGOs) operate within working equid communities providing veterinary care, education and training programmes aimed at improving equine welfare. However, there is little published information available that describes monitoring and ev...
Cooper JJ, McDonald L, Mills DS.Stabled horses commonly perform stereotypic patterns of weaving, where the horse shifts its weight from side to side often swinging its head. Ten warm-blood types, of which five were known to reliably weave, were housed in similar 12x12 ft wooden loose boxes in a single stable block surrounding a courtyard. Each horse was exposed to each of five stable designs. These were: the conventional front top-half of the door open only with a view of the stable courtyard (F); front half-door open and a similar half-door open at the back of the stable with a view to the surrounding fields (FB); back open...
Henderson AJ.This article posits that stereotypical behavior patterns and the overall psychological well being of today's performance horse could be substantially enhanced with care that acknowledges the relationship between domesticated horses and their forerunners. Feral horses typically roam in stable, social groups over large grazing territories, spending 16-20 hr per day foraging on mid- to poor-quality roughage. In contrast, today's elite show horses live in relatively small stalls, eat a limited-but rich-diet at specific feedings, and typically live in social isolation. Although the horse has been d...
McGreevy PD, Oddie C, Burton FL, McLean AN.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 ho...
Padalino B, Raidal SL, Carter N, Celi P, Muscatello G, Jeffcott L, de Silva K.Horses are transported frequently and often over long distances. Transportation may represent a physiological stressor with consequential health and welfare implications. This study reports the effects of a long distance journey on immunological, clinical, haematological, inflammatory and oxidative parameters in an Experimental Group (EG) of ten horses, comparing them with six horses of similar age and breed used as a non-transported Control Group (CG). Clinical examination and blood sampling were performed twice on all horses: immediately after unloading for the EG, and at rest on the same da...
Malinowski K, Yee C, Tevlin JM, Birks EK, Durando MM, Pournajafi-Nazarloo H, Cavaiola AA, McKeever KH.With the increase in the number of horses being used in Equine-Assisted Activities and Therapies (EAAT) programs and with the increasing concern for animal welfare, it is important to understand the impact of such interventions on the stress level and quality of life for the horses involved. The purpose of the present pilot study was to test the hypothesis that participation in EAAT would acutely alter physiological markers of stress and well-being, including plasma cortisol, plasma oxytocin, and heart rate variability (HRV), in horses and that symptoms of posttraumatic stress disorder (PTSD) ...
Taylor PM, Pascoe PJ, Mama KR.This chapter begins by providing an overview of current philosophies relevant to equine pain management. Objective and subjective techniques for assessing pain and the limitations of these are then described in depth. The conclusion emphasizes the need for an evidence based approach to managing pain in the horse and sets the stage for subsequent chapters in this edition.
Lesimple C, Fureix C, De Margerie E, Sénèque E, Menguy H, Hausberger M.Postures have long been used and proved useful to describe animals' behaviours and emotional states, but remains difficult to assess objectively in field conditions. A recent study performed on horses using geometric morphometrics revealed important postural differences between 2 horse populations differing in management conditions (leisure horses living in social groups used for occasional "relaxed" riding/riding school horses living in individual boxes used in daily riding lessons with more constraining techniques). It was suggested that these postural differences may reflect chronic effects...
Rørvang MV, Nielsen BL, McLean AN.Vision, hearing, olfaction, taste, and touch comprise the sensory modalities of most vertebrates. With these senses, the animal receives information about its environment. How this information is organized, interpreted, and experienced is known as perception. The study of the sensory abilities of animals and their implications for behavior is central not only to ethology but also to animal welfare. Sensory ability, perception, and behavior are closely linked. Horses and humans share the five most common sensory modalities, however, their ranges and capacities differ, so that horses are unlikel...
Munsters CC, Visser KE, van den Broek J, Sloet van Oldruitenborgh-Oosterbaan MM.A good horse-rider 'match' is important in the context of equine welfare. To quantify the influence of repetition and horse-rider matching on the stress of horses encountering challenging objects, 16 Warmblood horses were ridden in a test-setting on three occasions. On each occasion the horse was ridden by a different rider and was challenged by three objects (A-C). Heart rate (HR), heart rate variability (HRV) of horse and rider, and behaviour score (BS) of the horse were obtained for each object and as a total for each test. The horse-rider interaction was evaluated with each combination and...
