Guttural pouch tympany or empyema in 38 ٍStraight Egyptian Arabian foals: clinical presentation, diagnostic features and outcome. As a breed, Straight Egyptian Arabian horses are susceptible to many disorders that mostly affect the head, such as guttural pouch (GP) tympany and empyema. This retrospective study evaluated the findings of clinical examination, ultrasonography, endoscopy, laboratory analyses and outcome of treatment of 38 Straight Egyptian Arabian foals with GP tympany and empyema. Methods: Data from medical records of foals diagnosed with GP tympany or empyema over a 2-year period (2024-2025) were reviewed. Foals with verified GP tympany or empyema who had complete medical records and had not previously rec...
Hepatic encephalopathy associated with extensive hepatic diaphragmatic herniation in an adult horse. Diaphragmatic hernia in horses is a rare condition, most commonly presenting with signs of colic and, less frequently, respiratory compromise. Hepatic herniation through a diaphragmatic defect with secondary hepatic failure and encephalopathy has rarely been documented in horses. Methods: A 5-year-old Mangalarga Marchador stallion was evaluated for progressive neurological deterioration, including obtundation, head pressing, ataxia, and circling. Serum biochemistry revealed severe hepatobiliary dysfunction, characterised by increased gamma-glutamyl transferase and alkaline phosphatase activiti...
Preliminary investigation of ghrelin in horses and ponies: receptor expression and associations with prandial state, morphometry and signalment. The hormone ghrelin has had limited attention in Equidae, despite connections with appetite and metabolic health in other species. Ghrelin influences hunger and food intake, energy expenditure and storage, glucose metabolism, and thermoregulation, through its receptor-mediated effects on tissues and via interaction with other hormones. There are two circulating forms, acylated and des-acylated ghrelin, considered to have distinct effects on metabolism in other species. The aims of this study were to confirm the presence of ghrelin receptors in equine tissues, to validate an assay for the measu...
Detecting and measuring respiratory events in horses during exercise with a microphone: deep learning vs. standard signal processing. Monitoring respiration parameters such as respiratory rate could be beneficial to understand the impact of training on equine health and performance and ultimately improve equine welfare. In this work, we compare deep learning-based methods to an adapted signal processing method to automatically detect cyclic respiratory events and extract the dynamic respiratory rate from microphone recordings during high-intensity exercise in Standardbred trotters. Results: Our deep learning models are able to detect exhalation sounds (median F1 score of 0.94) in noisy microphone signals and show promising r...
Assessment of pharmacokinetic parameters, oral bioavailability, and physiological effects of amantadine in horses. Without adequate pain management, central nervous system plasticity can result in acute or adaptive pain developing into chronic or maladaptive pain. This is difficult to manage and often unresponsive to traditional analgesics. An important mechanism associated with maladaptive pain is central sensitization which results in part from increased NMDA (N-methyl-D-aspartate) receptor activation. Amantadine is an NMDA receptor antagonist that has been used in combination with opioids and NSAIDs in humans and dogs for the treatment of conditions associated with central sensitization. The goal of the...
Exploration of the relationship between laboratory stress parameters and leukocyte coping capacity in ponies exposed to repetitive handling during a research project. Stress is an umbrella term indicating increased allostatic load with the potential to reach a pathological state of the organism. In this context, cortisol concentration and neutrophil granulocytes-to-lymphocyte ratio (NEU: LYM) are expected to increase. On the functional pathway, stress reduces the oxidative burst capacity of neutrophils and therefore, the leucocyte coping capacity (LCC) quantifying this oxygen radical generation of neutrophils. Therefore, we hypothesized that in ponies subjected to repetitive handling, LCC will decrease and will be negatively correlated with cortisol concent...
A multimodal approach to equine thoracolumbar myofascial pain: integrating clinical examination, AI-based gait analysis, and the ridden horse pain ethogram. Myofascial pain syndrome (MPS) is considered highly prevalent in horses, yet it is frequently underdiagnosed due to limited understanding of its clinical presentation and functional consequences, as well as the inherent challenges associated with its clinical assessment and objective measurement. In equines, the relationship between palpation-based MPS indicators, gait asymmetries, and pain-related behaviours during ridden work remains unclear. The primary aim of this study was to evaluate the association between thoracolumbar palpation pain scores and gait asymmetries measured in-hand and dur...
Effects of supplementing concentrates with different energy levels on growth performance, blood indicators, and fecal microbiota of Mongolian horses in late gestation. Horse breeding and management have a globally extensive history, with horses serving vital roles in transportation, warfare, agriculture, and cultural activities. In China, particularly in Inner Mongolia, the horse industry faces challenges such as harsh winters and limited nutritional research for local breeds, especially during late gestation. This critical period is essential for fetal development and maternal health, and inadequate nutrition can lead to complications like nutritional abortions and poor foal growth. Similar issues exist worldwide in cold climates or regions with seasonal pa...
Establishment and evaluation of hematological and serum biochemical reference intervals in Chinese local donkey populations. Background: Reliable interpretation of hematological and serum biochemical test results in donkeys benefits from the use of population- and management-system-adapted reference intervals (RIs). However, standardized and CLSI-compliant RIs for Chinese local donkeys are still unavailable, limiting their clinical and epidemiological application. This study aimed to establish hematological and serum biochemical RIs for Chinese local donkeys using a large, multi-farm dataset, and to evaluate the effects of farm origin, age, and sex on these parameters.

Over the past dozen years, Europe has experienced numerous WNF outbreaks of varying severity, leading to significant public health and economic impacts. Consequently, WNF has emerged as a major concern for both public health and veterinary sectors. In this study, we employed spatiotemporal analysis techniques alongside an optimized ecological niche model to investigate the spatiotemporal distribution patterns of historical WNF outbreaks, pre...
The effects of citrulline on horse milk components and fecal metabolism were analyzed based on LC-MS and 16s amplicon. The lactation period in mares is critical, as it significantly influences foal health and subsequent reproductive outcomes. Developing a precise nutritional strategy for lactating mares is a primary research focus. L-citrulline, a bioactivenon-protein amino acid and precursor to arginine, has been shown to enhance mammary blood flow and reduce oxidative stress, yielding promising results in livestock lactation studies. However, research on its effects in Equus species remains limited. There is a notable gap in data regarding its impact on lactation performance blood biochemistry, and its role ...
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 ...

Antibacterial use in Norwegian horses: a nationwide registry-based cross-sectional study. BACKGROUND: Antibacterials are essential for treating infections in horses, but the use contributes to antimicrobial resistance (AMR), which threatens animal and human health. Despite these concerns, antibacterial use in horses has not been systematically studied and described in Norway, and nationwide registry-based analyses in other countries are scarce. The aim of this study is to describe antibacterial use in Norwegian horses, 2022–2024, by analysing nationwide registry data, with a particular emphasis on gynecological and obstetrical conditions. In addition, we will evaluate the data qu...
Erythrocyte sequestration of metformin in horses: impact on matrix-specific pharmacokinetics and detection windows. BACKGROUND: Metformin is used for the treatment of type 2 diabetes and is one of the most prescribed medications in human medicine. It is less commonly prescribed in equine medicine, and its use is tightly regulated in several performance horse disciplines. In horseracing, it is considered a banned substance. A previous pharmacokinetic study of metformin in horses demonstrated a prolonged, unpredictable elimination phase. In the current study it was hypothesized that this was due to sequestration of metformin in a “deep” compartment, specifically red blood cells. This could result in pharm...
Exploratory evaluation of equine placental extract supplementation on ageing indicators in geriatric dogs: a single-arm pre-post study. BACKGROUND: Recent advances in preventive veterinary healthcare, nutritional management, and owner engagement have extended the longevity of domestic dogs. However, this increased lifespan has led to a higher prevalence of age-associated physiological and functional decline. Equine placental extract contains a variety of bioactive constituents, with reported antioxidative and anti-inflammatory properties. Although the use of equine placental extract in veterinary practice is expanding, empirical evidence supporting its effects on ageing-related clinical outcomes in dogs remains limited. In thi...

This study aimed to investigate plasma metabolomic alterations associated with prolonged aerobic exercise using untargeted liquid chromatography–high-resolution mass spectrometry (LC-HRMS). RESULTS: Plasma samples from twelve trained Arabian horses were collected before and after 80-km endurance rides and analyzed using both hydrophilic interaction (HILIC) and reversed-phase (C18) chromatographic platforms...
Effects of L-selenomethionine supplementation on nutrient digestibility and metabolism, antioxidant capacity, hormone levels, and fecal microbiota diversity in pregnant Yili mares during mid- to late gestation. L-selenomethionine (L-SeMet), a highly bioavailable organic form of selenium, plays a critical role in maintaining antioxidant homeostasis, regulating reproductive hormone secretion, and improving intestinal microbial ecology. Previous studies have demonstrated that appropriate supplementation with L-SeMet can significantly enhance the production performance and health status of ruminants. However, the nutritional regulatory mechanisms and physiological effects of L-SeMet in monogastric herbivores, particularly horses during mid- to late gestation, remain inadequately understood. Therefore, th...
RNA-seq evaluation of equine alveolar macrophages and monocyte-derived macrophages exposed to an inflammatory stimulus (short communication). Macrophage populations in the lung, including resident alveolar macrophages (AMs) and recruited monocyte-derived macrophages (MDMs), recognize the inhaled particulates in barn dust that cause severe equine asthma and orchestrate an immune response though the cytokines they produce. Despite their importance, the specific contributions of these macrophage subsets to lower airway inflammation remain poorly understood. This exploratory in vitro study investigated the likely contributions of AMs and MDMs from healthy horses to the early inflammatory response using RNA-seq. If biologically importan...

Biomechanical assessment of dressage Spanish horses through accelerometry and the immediate effects of a single capacitive resistive electrical transfer session. Capacitive resistive electrical transfer (CRET) is a non-invasive electromagnetic diathermic technique. The effect of its application 24 h prior to exercise, compared to a sham application performed with the device off, was evaluated in 8 Spanish Purebred dressage stallions. CRET was applied bilaterally on the neck, back, and croup. The horses wore an accelerometer fixed on the sternal area during a dressage test, and spatiotemporal stride parameters, total and dorsoventral (DVAA), longitudinal (LAA), and mediolateral accelerometric activities, as well as dorsoventral displacement, were recor...
Antibody responses to equine parapoxvirus reveal a re-emerging pattern. Parapoxviruses (PPV) cause skin and mucous membrane signs to several animal species and humans worldwide. Equine parapoxvirus (EqPPV) was first detected in a sick horse in Finland in 2013. It is potentially zoonotic, and a similar virus has been detected in humans in the USA. In winter 2021–2022, EqPPV caused a large-scale pastern dermatitis epidemic in racehorses all over Finland. Field reports suggest that similar epidemics of unverified cause have also occurred in 2015 and 2019. The aim of this study was to develop a serological test and study the immune response, seroprevalence, and hist...
Functional and molecular characterization of equine intestinal organoids across media conditions and intestinal segments. Gastrointestinal (GI) disease is a major cause of morbidity and mortality in horses, with disruption of the intestinal epithelial barrier playing a central role in disease pathogenesis. A deeper understanding of the molecular and functional properties of the equine intestinal barrier is essential to improve diagnostics and therapeutics. While intestinal organoids have emerged as a promising tool for modeling GI physiology and disease, equine-specific data remain limited. Existing studies vary in methodology and often lack functional characterization, particularly across different intestinal re...
Investigation of gene stability in equine luteal tissue during mid-diestrus phase and early pregnancy – Research Article. Real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) is a technique that allows for the semi-quantification of mRNA transcripts present within a tissue of interest. Differences in the relative abundance of mRNA between samples detected by RT-qPCR require normalization with a reference gene or genes whose transcript abundance is stable within the tissue of interest independent of experimental conditions. In the field of equine reproductive studies, ACTB, GAPDH and B2M genes are the most widely used as reference genes for the normalization of RT-qPCR results. However,...
