Blood pressure, electrolyte and fluid balance in horses with insulin dysregulation after short-term treatment with canagliflozin. Short-term treatment with SGLT-2 inhibitors decreases blood pressure in people with type 2 diabetes. The aim was to investigate the impact of a 3-week treatment with canagliflozin on blood pressure in insulin dysregulated (ID) horses and to study effects on fluid balance. This was a single-centre, randomised, double-blind, placebo-controlled, parallel design study. The primary study evaluated glucose and insulin responses during an oral sugar test, and these results have been published previously. Here we report the effect of canagliflozin treatment on blood pressure, PCV, serum proteins and e...
Equine piroplasmosis in China, 2000 to 2025: a systematic review and meta-analysis of prevalence and risk factors. Equine piroplasmosis (EP) is a tick-borne disease of equids caused by Theileria equi, Babesia caballi, and Theileria haneyi. We conducted a PRISMA-guided systematic review and meta-analysis to estimate pooled prevalence in China and identify associated risk factors. PubMed, Web of Science, ScienceDirect, CNKI, Wanfang, and VIP were searched through 15 August 2025. Of 2,626 records identified, 80 studies met the inclusion criteria. Random-effects models were used to pool prevalence estimates, and prespecified subgroup analyses and univariate meta-regression were used to explore heterogeneity an...
Airway Lipid Mediators in Horses: Baseline Bronchoalveolar Lavage Fluid Profiles and Effects of EPA and DHA-rich Microalgae Oil Supplementation. We investigated how dietary omega-3 polyunsaturated fatty acids (n-3 PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) affect airway inflammation, bronchoalveolar lavage fluid (BALF) lipid mediators and red blood cell fatty acids in horses. Increased BALF neutrophils are a hallmark of airway inflammation, commonly associated with equine asthma. The long-chain n-3 PUFAs EPA and DHA are essential nutrients and precursors of specialized pro-resolving mediators (SPMs) that regulate inflammatory responses. In this prospective field trial, we assigned horses to three diets, including...
Evaluating ex vivo toll-like receptor agonist response as a potential biomarker in equine gastric ulcer syndrome. Equine gastric ulcer syndrome (EGUS) is highly prevalent in horses. Despite its presumed painful nature, evaluation of objective biomarkers associated with EGUS presence and severity remains limited. The objective of this study was to investigate the potential of interleukin-1 beta (IL-1β) release by peripheral blood mononuclear cells (PBMCs) following ex vivo stimulation of toll-like receptors 2 and 4 (TLR2 and TLR4) as a potential biomarker for EGUS status, with gastric lesions used as a proxy for presumed EGUS-associated pain. Venous blood was collected from 77 horses, PBMCs were isolated ...
Mesenchymal stem cells in veterinary clinical practice: Evidence from naturally occurring diseases. Over the past two decades, the use of mesenchymal stem cells (MSCs) in veterinary medicine has expanded rapidly, although the clinical evidence remains in its early stages. This review discusses clinical studies involving client-owned animals with naturally occurring diseases in which MSCs or MSC-derived extracellular vesicles (EVs) were used as treatments. It covers musculoskeletal disorders, including osteoarthritis, tendon and ligament injuries, and bone diseases; soft-tissue and oral mucosal conditions; neurological disorders; ophthalmic diseases; and internal medicine disorders, such as i...
Failure of Passive Transfer in neonatal foals – a review. Failure of passive transfer (FPT) is a major contributor to morbidity and mortality in neonatal foals worldwide. Adequate ingestion and intestinal absorption of colostral immunoglobulin G (IgG) during the first hours of life are essential to ensure protection against early-life infections, such as diarrhoea and pneumonia, frequently with fatal outcome. This review summarizes current knowledge on the physiology of passive immunization, risk factors for inadequate IgG absorption, diagnostic methods, therapeutic strategies, and evidence-based preventive measures. Recent research highlights the im...
Environmental and genetic effects on measured hock bone proportions in young Polish Warmblood horses undergoing performance test training for breeding horses. The hock bone proportions in young Polish Warmblood horses (69) were studied based on x-ray image measurements done during official breeding horse performance testing. Six measurements were used to identify 4 width and length proportion indices. The radiological examinations were done before and after horse training, which consists of work with or without the rider at walk, trot and canter (40-50min) with some light class (< 100cm) jumping (<12 jumps) 6 days a week. The training effect was investigated using analysis of variance (procedure MIXED, Statistical Analysis System). The statist...
Morphological investigation of myocardial sleeves with potential relevance to atrial fibrillation in Norwegian-Swedish Coldblooded Trotters. Myocardial sleeves (MSs) are thin layers of cardiac muscle that extend from the atria into the caval and pulmonary veins. They are recognised as important structures in both initiating and maintaining atrial tachycardia, and especially atrial fibrillation (AF), which is the most clinically important cardiac arrhythmia in horses with a reported prevalence of 1.3-2% in Standardbred racehorses. In contrast, the Norwegian-Swedish Coldblooded Trotter (NSCT) has a much lower prevalence of AF despite experiencing similar physical demands. The purpose of this study was to describe the macro-, and micr...
The Role of Artificial Intelligence in Equine Colic: A Scoping Review of Diagnostic, Prognostic, and Decision-Support Applications. Equine colic remains one of the leading causes of mortality in horses, with timely diagnosis and accurate prognostic assessment being critical for clinical decision-making. In recent years, artificial intelligence (AI) has been increasingly applied to support diagnostic and prognostic evaluation in veterinary medicine. However, the scope, methodological characteristics, and performance of AI models in equine colic have not been systematically mapped. Therefore, this scoping review was conducted to summarize current AI applications in equine colic, identify commonly used algorithms, describe re...
Hair steroid hormones concentrations in jennies and their donkey foals from parturition to 6 months postpartum. The period after parturition/birth represents a delicate time for the dam and the offspring, during which several physiologic changes occur under finely tuned hormonal control, with the hypothalamic-pituitary- adrenal (HPA) axis playing a key role. This period, well studied in horses, received little attention in donkeys, despite the importance of species-specific knowledge for population preservation programs in many endangered donkey breeds. The present study aimed to investigate cortisol (C), DHEA(S), 17-β-estradiol (E2), progesterone (P4), testosterone (T), and allopregnanolone (AlloP) ha...
Circulating microRNAs as potential predictive biomarkers of equine metabolic syndrome. Equine Metabolic Syndrome (EMS) is a complex endocrine disorder characterized by insulin dysregulation (ID), and an increased risk of developing laminitis, often accompanied by generalized or regional adiposity. Despite growing awareness of EMS, early and accurate diagnosis remains challenging. In this pilot study, we investigated changes in the levels of circulating microRNAs (miRNAs) in plasma samples from horses diagnosed with EMS (n=13), compared to overweight/obese (OW/OB) non-ID horses (n=16) and healthy controls (n=16). Using a targeted OpenArray, followed by a Kruskal-Wallis and Dunn's...
Prevalence, molecular characterization and zoonotic potential of Cryptosporidium spp. in horses from diverse husbandry systems across four provinces of northern and eastern China. Cryptosporidium is an obligate intracellular zoonotic protozoan causing diarrheal disease in humans and animals globally. Horses have more frequent close contact with humans through equestrian sports, breeding, and cross-regional trade. However, comprehensive molecular epidemiological data on diverse equine husbandry systems in China are limited. We tested 412 fecal samples from horses across four Chinese provinces via small subunit ribosomal RNA (SSU rRNA) nested polymerase chain reaction (PCR). C. parvum and C. equi were subtyped using the 60 kDa glycoprotein (gp60) gene, and C. andersoni ...
Validation of measurable radiographic parameters for quantitative assessment of carpal and metacarpal bone morphology in foals. Radiographic morphometry provides a quantitative means to evaluate bone conformation in horses, yet validation of these parameters in foals has not previously been undertaken. This study aimed to determine the intra- and inter-rater repeatability and reproducibility of established carpal and third metacarpal (MC3) radiographic parameters in Thoroughbred foals and to establish baseline conformational data. Twenty Thoroughbred foals were radiographed without sedation from birth to 14 months of age at two-month intervals. Dorsopalmar carpal and lateromedial MC3 radiographs were obtained using sta...
New Insights in Heart Rate Variability Through Non-Linear Methods for Conditioning Assessment in Horses. Chronic exercise induces significant adaptations across multiple physiological systems due to increased metabolic demand. Heart rate variability (HRV) has emerged as a prominent, non-invasive method for monitoring fitness, enabling inference of sympathovagal balance from time-series variations in electrocardiograms. Notably, nonlinear analyses have a strong capacity to detect and estimate complex mechanisms underlying cardiovascular modulation. In this context, HRV was evaluated in the time and frequency domains, as well as through nonlinear methods, in 12 young purebred Arabian horses undergo...
Structural Features of the Equine Small Intestinal Mesenteric Attachment Predisposing to Rupture. Rupture of equine small intestine with formation of a pouch of ingesta within the mesentery has been reported in clinical colic cases. Multiple ex-vivo studies using anastomosed jejunum observed rupture into the mesentery, distant to the anastomosis. Both scenarios suggest the jejunum is predisposed to rupture at the mesenteric attachment. The aim of the study is to 1) document the location at which equine jejunal segments rupture when subjected to high intraluminal pressures, 2) identify predisposing anatomical features that may confer weakness at the point of rupture and 3) demonstrate jejun...
The anterograde tarsal venography enhances vessel visualization compared to the retrograde approach in horses. The objective of this study was to compare the number of vessels of the proximal venous access (ramus cranialis of vena saphena medialis) and the distal venous access (vena digitalis dorsalis communis II) for venography and, consequently, intravenous regional limb perfusion of the tarsal region. Seven horses underwent venographic examination of both hind limbs, divided into two groups: proximal venous access (PG) and distal venous access (DG). Rubber tourniquets were applied to the middle third of the tibia and the proximal third of the III metatarsal bone. Thirty mL of contrast was injected (...
Global prevalence and epidemiological determinants of African horse sickness: A systematic review and meta-analysis. African horse sickness (AHS) is a highly fatal, vector-borne viral disease of equids with substantial economic and animal health impacts, particularly in endemic regions. Despite numerous epidemiological studies, reported prevalence estimates remain highly variable, and a comprehensive quantitative synthesis is lacking. This study aimed to systematically evaluate and synthesize the global prevalence of AHS and to identify sources of epidemiological heterogeneity. A systematic review and meta-analysis were conducted following PRISMA 2020 guidelines, with the protocol registered in the Open Scie...
Effects of vatinoxan in horses sedated with detomidine and butorphanol for gastroscopy: a randomized clinical study. The peripheral alpha2-adrenoceptor antagonist vatinoxan attenuated the side effects of alpha2-adrenergic sedatives in experimental studies in horses. This clinical study investigated the effects of vatinoxan in horses sedated for gastroscopy with detomidine and butorphanol. Client-owned horses were randomly allocated to receive one of the following two intravenous treatments: detomidine hydrochloride (HCl) (12μg/kg) + butorphanol tartrate (12μg/kg) (DB; n=11) or DB + vatinoxan HCl (200μg/kg) (DBV; n=11). Borborygmi score and heart rate were recorded by auscultation. Sedation level was evalu...
Cardiac morphologic changes induced by a 10-week water treadmill training for show jumping horses: A preliminary evaluation. This study aimed to investigate cardiac adaptations and energy expenditure of jumping horses after water treadmill (WT) training. Six trained horses were evaluated before (PRETR) and after (TR) a WT training (20 min, twice/week, water at carpus height) for 10 weeks. Transthoracic echocardiography was performed at PRETR and TR with phased array transducer (1.9-4 MHz) to obtain interventricular septal thickness (IVS), LV internal diameter (LVID), and posterior wall thickness (LVPW) at end-diastole (d) and systole (s) and heart rate (HR). Left ventricule end diastolic volume (Vd) and end syst...
Temporal variation in incretin and insulin secretion in ponies in association with dietary macronutrients. Equine insulin dysregulation (ID) is a common condition that predisposes to hyperinsulinaemia-associated laminitis. Improved pathophysiological understanding would enable better management of ID and reduce the risk of laminitis. The incretin peptides, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), augment the insulin response to dietary glucose and GLP-1 has been implicated in the pathophysiology of ID. However, their temporal variation in response to a low-energy diet has not been reported. This study determined the variation in GLP-1, GIP and insulin ...
Equine lameness detection and monitoring during diagnostic anaesthesia with an instrumented hoof boot. Ground reaction forces are accepted as gold standard for objective assessment of weightbearing lameness but measurements at the hoof are limited to experimental devices. This study aimed to evaluate whether innovative instrumented hoof boots (IHBs) could detect and monitor lameness in horses during diagnostic anaesthesia. Twenty-six horses referred for lameness examination (15 front limbs, 17 hindlimbs) were equipped with IHBs and body mounted inertial sensors. Data were collected simultaneously before and after diagnostic anaesthesia until objectively considered positive. Recorded IHB data i...
Machine learning-based prediction and quantification of OCD surgery and pedigree effects on racehorse performance. Osteochondritis dissecans (OCD) is a common developmental orthopedic condition in Thoroughbred racehorses and although arthroscopic surgery is widely used for treatment, its long-term effects on race performance remain unclear. This retrospective study evaluated the effect of OCD surgery on race performance, compared the predictive power of pedigree and management variables and applied interpretable machine learning methods for forecasting race performance outcomes. Data were collected from 75 Thoroughbreds that underwent OCD surgery between 2015 and 2017 and 257 maternal siblings without reco...
More conservative use of antimicrobials does not adversely affect treatment outcomes in foal bronchopneumonia. The emergence of antimicrobial resistance raises concerns about using antibiotics in veterinary medicine, particularly in cases of bronchopneumonia in foals diagnosed early based on a screening programme. Many subclinical foals recover spontaneously, thus, interest in more restrictive antibiotic usage is increasing. Objective: To determine whether initiating antimicrobial therapy at a later stage of bronchopneumonia decreases antimicrobial usage without compromising successful resolution of pathology in affected foals. Methods: A total of 1200 warmblood foals born in 2020, 2022, 2023 and 2024 ...
Markers of bone turnover, parathyroid hormone, calcium, and magnesium concentrations in horses with acute colitis. Hypocalcemia is frequent in horses with colitis. Information on serum parathyroid hormone (PTH) concentrations and its association with bone turnover biomarkers in horses with colitis is lacking. We aimed to determine the association between serum bone resorption biomarkers (C-terminal telopeptide of type I collagen [CTX-I]) and bone formation (osteocalcin [OCN]) with blood PTH, total calcium (tCa), ionized calcium (iCa), phosphorus (Pi), and total magnesium (tMg) concentrations, and mortality in horses with acute colitis. A total of 163 horses were divided into colitis (n = 127) and healt...
TGF-β1 and estradiol modulate prostaglandin concentrations and related gene expression in equine endometrium during the follicular phase. Transforming growth factor (TGF)-β1 is a pro-fibrotic cytokine that affects extracellular matrix (ECM) deposition and fibroblast activity. 17β-Estradiol (E), the dominant ovarian steroid during the follicular phase (FLP) of the estrous cycle, can also influence ECM remodeling and fibrosis, through prostaglandin (PG) synthesis. PGs have opposing roles in fibrosis, with PGE₂ showing anti-fibrotic effects and PGF₂α promoting fibrosis. Equine endometrosis, whose main pathological feature is fibrosis, is marked by chronic inflammation and ECM accumulation, and may involve mediators like TGF-...
Generation and characterization of an immortalized equine osteoblast cell line. Bone is a dynamic tissue that is maintained through the co-ordination of bone resorption and bone formation. An imbalance of these processes can lead to bone disease. In vitro studies of osteoblasts can help to understand bone formation, but primary cells have a limited lifespan in culture. Herein, we report the successful generation of equine immortalized osteoblasts through the stable overexpression of human telomerase reverse transcriptase (hTERT) and Simian virus 40 (SV40) large T-antigen in osteoblasts isolated from trabecular bone taken from the third metacarpal of a two-year-old Thoroug...
Development and application of a focused ultrasound protocol in neonatal foals. This study aimed to develop a standardized ultrasound (US) protocol using selected thoracic and abdominal acoustic windows, to assess its feasibility and applicability in healthy foals, and to evaluate its usefulness for detecting common thoracic and abdominal conditions in sick foals. The Focused US (FUS) protocol included 12 thoraco-abdominal windows (4 right-side, 3 ventral, 5 left-side) using a curved-array probe. It was applied to cohorts of healthy (n = 17) and sick (n = 23) foals by a veterinary clinician with limited US experience. The FUS showed good feasibility and applicabil...
I feel your pain: Individual differences in welfare indicators after castration in horses. 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...
A GPS-based investigation into the relationship between exercise irregularity and osteochondritis dissecans in Thoroughbred weanlings: A case-control study. Osteochondritis dissecans (OCD) is a developmental orthopedic condition in young horses. Exercise and management affect OCD development, but the impact of exercise patterns during the 6-12 months growth period remains unclear. This study examined the association between OCD lesions in Thoroughbred foals and irregular exercise patterns. Forty foals wore halter-mounted Global Positioning System devices that recorded velocity every five seconds during turnout. Foals were routinely turned out for approximately 13 h daily, except on rainy days. Radiographs were taken at six and twelve months of a...
The impact of cumulative bone fatigue on musculoskeletal injury risk in racing Thoroughbreds. Musculoskeletal injuries (MSI) in racehorses are not typically spontaneous events, but develop gradually through cumulative cycles of loading over time. Stride characteristics can now be recorded with wearable technology, providing opportunity to quantify the skeletal impact of galloping over time. We estimated bone fatigue accumulation based on speed (m/s) and number of strides from n = 3168 race starts by n = 405 Thoroughbreds commencing racing in Tasmania, Australia between 2011 and 2016. The percentage bone fatigue accumulated was divided by various time periods (career, active car...
