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.
Spatiotemporal dynamics of equine group formation reveal the gradual emergence of social cohesion. Stable social relationships are essential for horse welfare, yet domestic management often involves regrouping unfamiliar individuals, potentially causing social stress. Fine-scale dynamics of social integration remain poorly quantified due to limitations of observational sampling. Using ultra-wideband real-time positioning, we tracked the development of spatial and social relationships in two newly formed equine groups (n = 19) over 2-12 months. Inter-individual distances decreased significantly, with time spent within 3 m of conspecifics increasing from 1.2 to 27.3% within two months, d...
Comparative clinical and thermographic responses to dexamethasone and saline solution mesotherapy in horses with spinal disorders. Back pain and spinal dysfunction in horses are multifactorial conditions frequently associated with musculoskeletal alterations that may impair mobility, performance, and welfare. Mesotherapy has emerged as a minimally invasive adjunctive approach for managing musculoskeletal disorders; however, comparative clinical responses to different intradermal protocols in equine spinal conditions remain insufficiently investigated. The present study aims to compare the clinical and thermographic responses of two mesotherapy protocols in horses diagnosed with cervical or thoracolumbar spinal disorders. ...
Could snort production reflect comfort in horses kept outdoors? A first study. The welfare of free-roaming, captive wild or domestic animals housed outdoors is often questioned. How subjects perceive climatic conditions is not always well detected as it is highly subjective, depending on species, age and experience. Hence, decisions on housing rely mostly on human anthropomorphic perception. In particular, indicators of comfort and positive emotions remain poorly documented. Acoustic signals, however, offer a promising window into animals' internal states. In the present study, we hypothesized that acoustic signals could be used to identify positive or negative perceptio...

Polygenic Prediction of Equestrian Sport Discipline Among Horses Bred for Jumping and Dressage. Horses bred for different equestrian sports vary in physical, physiological and behavioural requirements. Characterising genetic markers associated with discipline provides an opportunity to improve identification of horses best suited to either jumping or dressage. Using a composite selection signals test, genomic regions under positive selection in German warmblood horses divergent for discipline were identified that contained lead SNPs proximal to or within genes with functions relevant to the requirements for jumping and dressage. Dressage genes function in tortuosity of movement (GRM5) an...
Rider dislodgement events in U.S. steeplechase racing: participation outcomes in riders and horses. Steeplechase jockeys compete in high-risk races requiring horses and riders to clear fixed obstacles at speed. Although rider dislodgement events are recognized hazards, their incidence and participation consequences are not well characterized. Methods: This retrospective observational study used publicly available race charts from United States National Steeplechase Association races (2023-2025). Dislodgement events were defined as falls or lost rider events. Incidence rates were calculated per 1,000 starts, and timber and hurdle races were compared using Poisson regression. Rider interruptio...
Towards a Comprehensive Screening Approach for Detecting Gene Doping in Racehorses and Sport Horses by Targeting Common and Intrinsic Plasmid Sequences. The evolution of biotechnology and gene therapy has unfortunately facilitated the emergence of gene doping. Those misused applications are prohibited in equestrian sports (International Equestrian Federation (FEI)) and in horseracing (International Federation of Horseracing Authorities [IFHA]), reflecting major concerns regarding horse welfare and the integrity of competitions. Among the biotechnological tools that could be misused, eukaryotic expression plasmids represent a particular threat due to their ease of production, customisable design and ability to carry a wide range of performance ...

Positive Reinforcement (R+) Horse Training in Practice: Evaluation of Online Trailer-Training Demonstrations. Operant conditioning that includes primarily positive reinforcement (R+) has been shown to be an effective and welfare-friendly method of training horses. Despite this, operant conditioning and R+ are not fully understood by many horse trainers who claim to advocate for its use. Anecdotal observations suggest that some professional trainers who claim to use R+ do not use R+ primarily, even in publicly offered educational demonstrations. To better understand readily available training materials regarding the use of R+ with horses, we reviewed a sample of 20 online trailer-training demonstration...
Do Polish Konik Horses Find Soaked Hay to Be Palatable? Frequently, equine diseases necessitate the moistening or soaking of hay for the horses. It was assumed that this treatment would not reduce the willingness of the Polish Konik horses with low nutritional requirements to consume the hay. Furthermore, it was believed that moistening would increase the palatability of this feed. The aim of this study was to determine time and frequency parameters and the amount of unconsumed dry, moist, or soaked hay. The research material comprised 12 Polish Konik horses consuming either 1 kg of dry hay, 2.1 kg of moist hay, or 3.3 kg of soaked hay on three sub...

This study reports findings from an international online survey of 230 racing industry participants. It explored confidence in assessing racehorse emotions, the perceived importance of emotional state for perfo...
Open habitats and species differences shape space use in semi-feral cattle and horses across Danish rewilding sites. Large herbivores can strongly influence ecosystem structure and biodiversity, making knowledge of their space use important for trophic rewilding. We used GPS-tracking data collected over two years from 10 semi-feral cattle and 17 horses across ten Danish rewilding sites to analyse habitat use in a use-availability framework using resource selection functions (RSFs), complemented by direct behavioural observations. Both species showed large individual variability but overall used habitats disproportionately to availability, with higher relative use of open habitats; including dry grassland and...
Electromyographic activity of equine abdominal muscles during single and double riding in hippotherapy. Background: Hippotherapy is a therapeutic intervention that uses the horse as a biomechanical and sensorimotor agent to promote rehabilitation in individuals with physical and neurological disabilities. Depending on patient needs, riding may be performed with a single rider or with double riding, in which a therapist accompanies the practitioner on the horse. However, the effects of these riding configurations on equine trunk muscle activity remain poorly understood, despite their relevance for both horse welfare and the quality of therapeutic stimuli delivered to the patient.Methods: Nine cli...
Owner satisfaction and animal welfare after bilateral enucleation in horses.
