Topic:Welfare
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.
Evaluation of Systemic and Local Inflammatory Parameters and Manifestations of Pain in an Equine Experimental Wound Model. In the last decades, a well-established equine wound model has been used to study fibroproliferative wound healing disorders. The aim of this study was to characterize the degree of discomfort of wounding and sampling in an equine excisional wound model by evaluating systemic and local inflammatory responses and signs of pain. A total of 12 cutaneous wounds, three on each shoulder and each metatarsus, were created in a standing surgical procedure. Wounds were biopsied on days 2, 4, 7, 14, 21, and 28 after surgery. Clinical parameters (rectal temperature, heart rate, respiratory frequency) and ...
Can quantitative computed tomography detect bone morphological changes associated with catastrophic proximal sesamoid bone fracture in Thoroughbred racehorses? Fracture of the proximal sesamoid bones continues to be the most common fatal musculoskeletal injury in US racehorses. Identifying factors that influence fracture risk could lead to screening techniques to reduce catastrophic injury rates and improve animal welfare. Objective: To identify morphological differences between proximal sesamoid bones of the contralateral limb of fracture and control horses and assess the feasibility of computed tomography (CT) to detect traits associated with proximal sesamoid bone fracture. We hypothesised that horses with proximal sesamoid bone fracture would hav...
Effects of Rider Experience Level on Horse Kinematics and Behavior. There is little information on behavioral and physical effects of lesson horses being used multiple times a day or ridden by riders of varying levels of skill, leaving lesson program managers with limited information to support horse management and welfare decisions. This study used video analysis to evaluate whether horses exhibited different limb kinematics or patterns of behavior under riders with differing levels of experience, factors that could impact physical effort by the horse. Riders (n = 8) were sorted by skill level (four beginner and four advanced), and horses (n = 8) were sorte...
Contracting for care – the construction of the farrier role in supporting horse owners to prevent laminitis. Emerging research highlights how, due to demographic changes in horse owner populations in Western societies, complex owner-horse relationships are leading to inappropriate horse care, including overnutrition, which in turn can lead to laminitis. Farriers, due to their regular visits, may be in a position to support owners in dealing with this problem. Objective: This study explored whether UK farriers have a role in working with horse owners to support horse welfare and prevent laminitis. Methods: Grounded theory analysis, a qualitative methodology. Methods: Semi-structured interviews were co...
Pathological classification of equine recurrent laryngeal neuropathy. Recurrent Laryngeal Neuropathy (RLN) is a highly prevalent and predominantly left-sided, degenerative disorder of the recurrent laryngeal nerves (RLn) of tall horses, that causes inspiratory stridor at exercise because of intrinsic laryngeal muscle paresis. The associated laryngeal dysfunction and exercise intolerance in athletic horses commonly leads to surgical intervention, retirement or euthanasia with associated financial and welfare implications. Despite speculation, there is a lack of consensus and conflicting evidence supporting the primary classification of RLN, as either a distal ("d...
The use of a rein tension device to compare different training methods for neck flexion in base-level trained Warmblood horses at the walk. Debate surrounds the use of high rein tension for obtaining different head and neck positions in the training of sport horses on account of possible welfare issues. Objective: To compare auxiliary rein tension in two methods (Draw Reins and Concord Leader) for obtaining a standardised head and neck position on a hard and a soft surface. Methods: Intervention study. Methods: Left and right rein tensions were measured in 11 base-level trained client-owned sport horses (mean age ± s.d.; 10 ± 3.2 years) exercised in-hand with, in a random order, conventional draw reins or the newly developed Con...
Coat Clipping of Horses: A Survey. Coat clipping is a common practice in sport horses; however, timing, purpose, technique, and clips vary widely, as do the management and feeding of a clipped horse. The aim of this study was to collect data regarding common clipping practices. A questionnaire was published online in Germany and contained 32 questions. Four hundred ninety-eight people answered at least one question, and 373 individuals (7% male, 93% female; ages 14-59 years) completed all the questions. Clipped horses were predominantly used as sport horses (68%), and they were either clipped immediately before or during the w...
Lesions associated with the use of bits, nosebands, spurs and whips in Danish competition horses. 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...
Risk factors for race-day fatality in flat racing Thoroughbreds in Great Britain (2000 to 2013). A key focus of the racing industry is to reduce the number of race-day events where horses die suddenly or are euthanased due to catastrophic injury. The objective of this study was therefore to determine risk factors for race-day fatalities in Thoroughbred racehorses, using a cohort of all horses participating in flat racing in Great Britain between 2000 and 2013. Horse-, race- and course-level data were collected and combined with all race-day fatalities, recorded by racecourse veterinarians in a central database. Associations between exposure variables and fatality were assessed using logis...
Using the Five Domains Model to Assess the Adverse Impacts of Husbandry, Veterinary, and Equitation Interventions on Horse Welfare. The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were consid...
Physiological responses in horses, donkeys and mules sold at livestock markets. The horse welfare at markets includes fatigue, fear, fasting, dehydration and injuries. However, the scientific literature contains no readily-available information on the physiology responses of equids sold in livestock markets. The objective of the present study was to evaluate the effect of holding in livestock markets on gas exchange, the acid-base balance, energy metabolism, and the mineral and water balance in 4 types of horses (), donkeys () and mules (( × ). To this end, a total of 1,438 equine were utilized, after classification into six groups, as follows: mules, donkeys, culled...
Longitudinal trends in the frequency of medium and fast race winning times in Australian harness racing: Relationships with rules moderating whip use. The use of whips in racing is subject to current debate, not least because the prospect that fatigued horses cannot respond renders the practice futile and inhumane. The racing industries maintain whip use is a form of encouragement and that the rules of racing that govern whip use safeguard horse welfare. The current study examined longitudinal trends in the frequency of medium and fast race winning times in Australian harness racing between September 2007 and August 2016 to explore relationships with a series of changes that moderated whip use. The first change, introduced January 2010, mode...
Changes in hoof kinetics and kinematics at walk in response to hoof trimming: pressure plate assessment. Appropriate hoof preparation and symmetry are linked to the well-being of the horse. Previous studies have shown the efficacy of pressure plates (PPs) in delivering objective biomechanical analysis. We aimed to assess the effect of hoof trimming on hoof biomechanics using a PP. Nine clinically sound Arabian horses were walked across a PP while foot strike was recorded by a digital camera. Kinetic and kinematic parameters were recorded before and after trimming. Changes were considered significant when ＜ 0.05. Vertical force ( = 0.026) and contact pressure ( = 0.006) increased after trimming...
Epidemiology of fractures: The role of kick injuries in equine fractures. Fractures occur commonly in equids and often are associated with complications and a poor outcome. There are no reports on the epidemiology of fractures in a heterogeneous equine population. Objective: To study the epidemiology of fractures in a heterogeneous equine population, focusing on differences between fractures resulting from a kick and fractures, resulting from other causes and investigating predictors for recovery. Methods: Retrospective case series. Methods: Data of all equids presented to the Equine Department, Vetsuisse Faculty, University of Zurich between 1990 and 2014 and diagn...
Characterization of the Prevalence and Management of Over-Conditioned Ponies and Horses in Maryland. It has been estimated in the United States and abroad that 20%-51% of the equine population suffers from over-conditioning or obesity. The objective of this study was to evaluate the prevalence of over-conditioning in the equine population in Maryland, to characterize weight control measures used, and to ascertain how control measures impact the operation. Over-conditioning was defined as a body condition score of 4 or 5 on a 5-point scale. All licensed horse operators in Maryland were invited to participate in an online survey. A total of 93 farm operators completed the survey with 238 ponies...
Effect of Dental Correction on Fecal Fiber Length in Horses. The aim of the study was to determine if dental correction changes fecal fiber length (FFL) in horses that had never been subjected to dental treatments. Thirty adult horses with mild to moderate dental abnormalities were selected. Dental disorders noted included sharp enamel points, focal overgrowths, shear mouth, step mouth, wave mouth, accentuated transverse ridges, and diastema. The horses were confined to individual stalls and fed Tifton hay (Cynodon spp.) 1.5% bwt/d, divided equally between two feedings. Fecal samples were taken for FFL analysis before (Day 0) and after (Day 15) dental c...
Re-evaluation of the regulation of omeprazole in racehorses: An evidence-based approach. Medication control and doping control have been established in horse racing to ensure the integrity of the sport and the welfare of the horses. This ensures that horses do not compete under the influence of any drugs, including omeprazole, a therapeutic medication used to treat equine gastric ulcer syndrome. In this study, pharmacokinetic data were produced in equine plasma and urine following an oral administration of 4 mg/kg of generic buffered formulation of omeprazole to six Thoroughbred horses in five daily doses to determine an appropriate screening limit and detection time in equine pl...
A standardised equine-based welfare assessment tool used for six years in low and middle income countries. The majority of horses, donkeys and mules (equids) are in low- and middle-income countries, where they remain a key source of labour in the construction, agriculture and tourism industries, as well as supporting households daily through transporting people and staple goods. Globally, approximately 600 million people depend on working equids for their livelihood. Safeguarding the welfare of these animals is essential for them to work, as well as for the intrinsic value of the animal's quality of life. In order to manage animal welfare, it must be measured. Over the past decade, welfare assessme...
Flogging tired horses: Who wants whipping and who would walk away if whipping horses were withheld? Recent studies have cast doubt on the effectiveness of whipping horses during races and this has led to questions concerning its continuing justification. Furthermore, it has been argued that whipping tired horses in racing is the most televised form of violence to animals. The present study used de-identified data from a recent independent Australian poll (n = 1,533) to characterise the 26% of respondents (113 females and 271 males) who support the whipping of racehorses and the 10% of racing enthusiasts in the sample (44 females and 63 males) who would stop watching races and betting on them...
The Effects of Equine Assisted Therapy on Plasma Cortisol and Oxytocin Concentrations and Heart Rate Variability in Horses and Measures of Symptoms of Post-Traumatic Stress Disorder in Veterans. 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) ...
Horse Husbandry and Preventive Health Practices in Australia: An Online Survey of Horse Guardians. Little is known about the horse health management practices of Australian horse caregivers (owners). This article presents findings from a convenience sample of 505 horse owners who participated in an online survey. No large-scale welfare issues were identified, but there were some areas of potential concern, including owners who did not regularly deworm their horses (4%), a lack of strategic parasite control (3.1%), and a lack of regular dental care (11%). Several participants did not have their horse's hooves regularly shod or trimmed (2%), and 14% had an unqualified person maintain their ho...
Improving working equine welfare in ‘hard-win’ situations, where gains are difficult, expensive or marginal. Brooke is a non-government organisation with working equine welfare programmes across Africa, Asia and Latin America. In 2014, staff from ten country programmes were asked to identify 'no-win' situations (subsequently reframed as 'hard-wins')-where improving equine welfare is proving difficult, expensive and/or marginal-in order to inform strategic decisions on how to approach, manage and mitigate for such situations. The Delphi-type consultation process had three phases. Round 1 posed five questions in the form of a workshop, survey and semi-structured interviews. Round 2 re-presented key the...

Sudden death affects the health of horses, the safety of riders and the public perception of animal welfare during equestrian events. Objective: To describe the signalment, clinical history, sudden death episode, rider injuries and causes of sudden death during exercise or closely thereafter in sport and pleasure riding horses. Methods: Retrospective case series based on an online questionnaire. Methods: An online questionnaire was distributed to the veterinary and equestrian community. Connections of animals reported in the press to have died suddenly were sent the survey. Responses were anal...
The contribution of total and free iodothyronines to welfare maintenance and management stress coping in Ruminants and Equines: Physiological ranges and reference values. In order to acquire a pattern of thyroid involvement in welfare maintenance in Ruminants and Equines, this review summarizes data concerning the reference values of total and free iodothyronines and their modifications in physiological conditions and in different management conditions (pregnancy, lactation, weaning, growth, isolation, restraint, shearing, confinement and transportation). Thyroidal and extrathyroidal tissues efficiently respond to management practices, giving a differentiated contribution to circulating iodothyronine changes. The hormonal response could be mainly attributed to ...
A Pilot Qualitative Investigation of Stakeholders’ Experiences and Opinions of Equine Insect Bite Hypersensitivity in England. Equine insect bite hypersensitivity (IBH), commonly known as sweet itch or summer eczema, is a frustrating recurrent skin disease in the equine industry involving an immune reaction to the bites of spp. midges. To investigate the impact of IBH in the field, an exploratory pilot study was conducted with equine stakeholders in one region of central England. Nine semi-structured, face-to-face interviews were conducted with horse owners and an equine veterinarian. The aim was to gain an understanding of experiences with IBH, and to gauge opinions on the value of the various management strategies ...
An Indication of Reliability of the Two-Level Approach of the AWIN Welfare Assessment Protocol for Horses. To enhance feasibility, the Animal Welfare Indicators (AWIN) assessment protocol for horses consists of two levels: the first is a visual inspection of a sample of horses performed from a distance, the second a close-up inspection of all horses. The aim was to analyse whether information would be lost if only the first level were performed. In this study, 112 first and 112 second level assessments carried out on a subsequent day by one observer were compared by calculating the Spearman's Rank Correlation Coefficient (RS), Intraclass Correlation Coefficients (ICC), Smallest Detectable Changes (...
