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.

The impact of barefoot racing in young Swedish trotters on career length. In several European countries, racing without shoes, i.e., barefoot, is a common strategy in trotting races to improve the speed of the horse. Why some trotters can race barefoot without damage to the hoof from excessive wear and others cannot, has been shown to partly be explained by differences in hoof composition. In particular, durable hind hooves are believed to be important to sustain racing without shoes. Also, variation in the proportion of the races the horse races with barefoot hind hooves, has been shown to be affected by genetic differences in Swedish Standardbred trotters (SB) and...
Welfare Assessment in Equine-Assisted Service (EAS) Horses. Equine-Assisted Service (EAS) horses can be exposed to stressors that affect their behavior and welfare. Previous studies investigated behavioral and physiological indicators (PI) only during therapy sessions. This study evaluated the frequency of stress and pain behaviors (FSPB) in horses with different riders, while assessing welfare through housing, management, and PI. Ten horses were observed during EAS sessions with three rider groups: able-bodied, clients with significant physical impairment, and clients with no significant physical impairment, totaling twenty-six riders. Behavioral data...
Beyond cortisol: evaluating serotonin, brain-derived neurotrophic factor, and oxytocin as indicators of equine welfare across three training regimens. BACKGROUND: Quantifying the balance between workload, stress, and recovery across equine disciplines remains challenging, and no single circulating biomarker provides a definitive index of welfare-related stress load. Cortisol, oxytocin, serotonin (5-hydroxytryptamine, 5-HT), and brain-derived neurotrophic factor (BDNF) may provide complementary information on endocrine and neuromodulatory responses. METHODS: Paired serum samples were collected from show jumping horses (n = 17) before and after competition, racehorses (n = 43 enrolled, n = 41 analyzed) before and after sessions at ...
A service provider perspective in Irish horseracing on the availability of retirement specific support services for professional jockeys and perceived barriers and facilitators to their use.
