Veterinary care also involves diagnostic procedures, surgical interventions, and therapeutic treatments tailored to the specific needs of horses. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Lamellar events related to insulin-like growth factor-1 receptor signalling in two models relevant to endocrinopathic laminitis. Insulin dysregulation, obesity, and exposure to high-nonstructural carbohydrate (NSC) forage are risk factors for equine metabolic syndrome-associated laminitis (EMSAL); high systemic insulin concentrations in EMSAL are proposed to induce cellular dysregulation in the digital lamellae through activation of the insulin-like growth factor-1 receptor. Objective: To use a dietary challenge model (DCM) and a euglycaemic-hyperinsulinaemic clamp (EHC) model to assess lamellar growth factor-related signalling. Methods: Lamellar phospho (P)-protein concentrations of signalling proteins important in gro...
Veterinary problems of endurance horses in England and Wales. Several studies have shown that a considerable proportion of horses are eliminated from endurance rides due to lameness and metabolic problems. Limited information is available on specific veterinary issues in endurance horses and there are no descriptive data on veterinary problems in a large population of endurance horses. The aim of this study was to describe veterinary problems occurring in endurance horses in England and Wales, the regions of the United Kingdom where endurance rides are organised and regulated by Endurance Great Britain (Endurance GB). A comprehensive online self-complete...
Purified horse milk exosomes contain an unpredictable small number of major proteins. Exosomes are 40-100 nm nanovesicles containing RNA and different proteins. Exosomes containing proteins, lipids, mRNAs, and microRNAs are important in intracellular communication and immune function. Exosomes from different sources are usually obtained by combination of centrifugation and ultracentrifugation and according to published data can contain from a few dozens to thousands of different proteins. Crude exosome preparations from milk of eighteen horses were obtained for the first time using several standard centrifugations. Exosome preparations were additionally purified by FPLC gel fi...
Efficacy of a morantel-abamectin combination for the treatment of resistant ascarids in foals.

Methods: Foals on five properties with a Parascaris faecal egg count (FEC) > 50 eggs per gram were used to estimate the FEC reduction (FECR) and efficacy of the anthelmintic combination. Conclusions: On all properties, resistance to ivermectin and abamectin was present and the Parascaris FECR in foals administered the morantel-abamectin combination was > 99%, indicating that this combination effective...
An ultrasound-guided, tendon-sparing, lateral approach to injection of the navicular bursa. Navicular disease in the horse often requires injection of the navicular bursa. We have developed an ultrasound-guided, lateral needle approach to navicular bursocentesis, which avoids penetration of the deep digital flexor tendon (DDFT) and the need for radiographic control. Objective: To describe and evaluate the feasibility and efficacy of an ultrasound-guided, lateral bursocentesis technique. Methods: Cadaveric and in vivo experiments. Methods: The navicular bursa in 62 cadaveric forelimbs of 31 horses and in both forelimbs of 26 live horses, positioned with the foot flexed in a navicular ...
Clinical study evaluating the accuracy of injecting the distal tarsal joints in the horse. Osteoarthritis (OA) of the centrodistal (CD) and tarsometatarsal (TMT) joints is a common cause of lameness in horses. Intra-articular diagnostic anaesthesia and/or therapeutic injection are relied upon to help diagnose and treat many horses with OA of these joints. Objective: The objective of this study was to determine the accuracy of arthrocentesis of the CD and TMT joints using a sample population of equine surgeons and surgery residents. Methods: Randomised experimental study. Methods: Six operators each injected four CD and four TMT joints in 12 sedated horses. The operators were randoml...
Gastrointestinal Pharmacology. There is little evidence for most of the medications currently used to treat functional abdominal pain disorders (FAPDs) in children. Not only are there very few clinical trials, but also most have significant variability in the methods used and outcomes measured. Thus, the decision on the most appropriate pharmacological treatment is frequently based on adult studies or empirical data. In children, peppermint oil, trimebutine, and drotaverine have shown significant benefit compared with placebo, each of them in a single randomized clinical trial. A small study found that cyproheptadine was be...
Long-term follow-up of Norwegian horses affected with acquired equine polyneuropathy. Acquired equine polyneuropathy (AEP), a neurological disease clinically characterised by knuckling of metatarsophalangeal joints, has been described in numerous Nordic horses during the last 20 years. Although clinical recovery has been reported, large-scale data on long-term follow-up of survivors have been lacking. Objective: To describe long-term survival of AEP affected horses registered in Norway, with a focus on athletic performance and possible residual clinical signs connected to the disease. Methods: A retrospective cohort study. Methods: The study includes 143 horses recorded with A...
An outbreak of psittacosis at a veterinary school demonstrating a novel source of infection. In November 2014, New South Wales Health was notified of a cluster of respiratory illness in a veterinary school. Active case finding identified another case at a local equine stud. All cases had exposure to the equine fetal membranes of Mare A. This tissue subsequently tested positive for Chlamydia psittaci using quantitative real-time polymerase chain reaction. We conducted a cohort study of the university and stud farm staff to determine risk factors for disease. Nine people were exposed to the fetal membranes of Mare A. Of these, five cases of psittacosis were identified. Two required hosp...
Proteomic, toxicological and immunogenic characterization of Mexican west-coast rattlesnake (Crotalus basiliscus) venom and its immunological relatedness with the venom of Central American rattlesnake (Crotalus simus). The venom of the Mexican west-coast rattlesnake (Crotalus basiliscus) was characterized for its protein composition, toxicological profile and immunogenic properties. This venom is composed of 68% Zn2+-dependent metalloproteinases (SVMPs), 14% phospholipases A2 (PLA2s), 11% serine proteinases, 4% SVMPs-inhibitor tripeptides (SVMP-ITs), 2% bradykinin-potentiating peptides (BPPs), 0.6% cysteine-rich secretory proteins (CRISPs), and 0.2% l-amino acid oxidases (LAAOs). SVMPs present in the venom are responsible for azocasein hydrolysis and hemorrhagic activity, but their contribution to the lethal...
Cross-sectional study of the prevalence of and risk factors for hoof disorders in horses in The Netherlands. Information is scarce on the prevalence of hoof disorders in horses. In this study, we examined the prevalence of and risk factors for hoof disorders in a population of horses in The Netherlands.

Gingival Fibrosarcoma in a Horse. A 4-year-old thoroughbred cross mare was referred to the University of Edinburgh Veterinary School Equine Hospital for treatment of a soft tissue tumor on the buccal gingival margin of the rostral right maxillary cheek teeth. The lesion was initially surgically excised and diagnosed as a fibrosarcoma via histopathology. Adjunctive treatment with intralesional cisplatin chemotherapy was begun. The tumor recurred and was repeatedly treated with intralesional cisplatin injections and additional surgical resection over the course of 14 weeks. Despite the initial poor response to treatment, no furt...
Sex chromosomal abnormalities associated with equine infertility: validation of a simple molecular screening tool in the Purebred Spanish Horse. Chromosomal abnormalities in the sex chromosome pair (ECAX and ECAY) are widely associated with reproductive problems in horses. However, a large proportion of these abnormalities remains undiagnosed due to the lack of an affordable diagnostic tool that allows for avoiding karyotyping tests. Hereby, we developed an STR (single-tandem-repeat)-based molecular method to determine the presence of the main sex chromosomal abnormalities in horses in a fast, cheap and reliable way. The frequency of five ECAX-linked (LEX026, LEX003, TKY38, TKY270 and UCDEQ502) and two ECAY-linked (EcaYH12 and SRY) mar...

Surgical mesh repair is an option for diaphragmatic defects. Un poulain né lors d’une parturition assistée a développé des fractures des côtes et une hernie diaphragmatique. La hernie a été réparée à l’aide d’un treillis chirurgical. La pouliche était en santé 42 mois plus tard. La dystocie est un facteur de risque ...
Comparative fibre-degrading capacity in foals at immediate and late post-weaning periods. Total tract apparent digestibility of dietary fibrous components and parameters of the faecal digestive ecosystem were compared at immediate and late post-weaning periods using five foals. The foals were abruptly weaned (day 0) from their mares at 6 months of age. Immediately (day 0 to day 14) and later (day 131 to day 194) after weaning, foals received the same basal diet consisting of hay and pellets. Pellets were fed at 0.36% BW. Hay was offered ad libitum and corresponded to 120% of the average voluntary hay intake measured individually during the immediate (days 1 to 4) and late (days 180...
Difficulties experienced by veterinarians when communicating about emerging zoonotic risks with animal owners: the case of Hendra virus. Communication skills are essential for veterinarians who need to discuss animal health related matters with their clients. When dealing with an emerging zoonosis, such as Hendra virus (HeV), veterinarians also have a legal responsibility to inform their clients about the associated risks to human health. Here we report on part of a mixed methods study that examined the preparedness of, and difficulties experienced by, veterinarians communicating about HeV-related risks with their clients. Methods: Phase 1 was an exploratory, qualitative study that consisted of a series of face-to-face, semi-st...
Nomenclature, classification, and documentation of catastrophic fractures and associated preexisting injuries in racehorses. Racehorses are susceptible to bone fractures when damage from repetitive, high-magnitude loads incurred during training and racing exceed concurrent damage removal and replacement, resulting in transient periods of focal osteoporosis and bone weakening. Clinically, these events correspond to cortical stress fractures and subchondral bone stress remodeling. Evidence of these preexisting lesions include periosteal callus, endosteal callus, and intracortical focal hyperemia for cortical stress fractures; and subchondral focal hyperemia located superficial to sclerotic compacted trabecular bone ti...
