Veterinary care in horses encompasses the medical and preventive measures taken to maintain and improve the health and well-being of equine patients. It includes a wide range of practices such as routine health examinations, vaccinations, dental care, parasite control, and management of injuries and diseases. 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.
Prevalence and some clinical characteristics of equine cheek teeth diastemata in 471 horses examined in a UK first-opinion equine practice (2008 to 2009). Cheek teeth (CT) diastemata are now recognised as a clinically significant equine disorder, but their prevalence in the general equine population is unknown. There is also limited information on the signalment of affected horses; the more commonly affected Triadan sites; and the shape and clinical characteristics of CT diastemata. During the 12-month study period (2008 to 2009), standardised records were obtained during routine dental examinations performed by five veterinarians in a first-opinion equine practice. Cheek teeth diastemata were identified in 49.9 per cent of all horses (n=471) of...
Evaluation of an automated assay based on monoclonal anti-human serum amyloid A (SAA) antibodies for measurement of canine, feline, and equine SAA. Major acute phase proteins (APPs) have proven diagnostically useful in dogs, cats and horses with routine use facilitated by commercially available automated heterologous assays. An automated assay applicable across all three species would highly facilitate further dissemination of routine use, and the aim of this study was to validate an automated latex agglutination turbidimetric immunoassay based on monoclonal anti-human serum amyloid A (SAA) antibodies for measurement of canine, feline and equine SAA. Serum samples from 60 dogs, 40 cats and 40 horses were included. Intra- and inter-assay i...
The implementation of biosecurity practices and visitor protocols on non-commercial horse properties in New Zealand. A survey was conducted to investigate biosecurity practices on non-commercial horse properties, to describe the number of visits by horse professionals and any protocols that visitors were required to follow before interacting with resident horses. Data were collected in November 2009 during a cross-sectional study of non-commercial horse properties, in New Zealand, selected using generalised random-tessellated stratified design and a self-administered postal questionnaire. Data were described and the associations between property-level factors and biosecurity practices were analysed using log...
Pregnancy rates in mares inseminated with 0.5 or 1 million sperm using hysteroscopic or transrectally guided deep-horn insemination techniques. Placement of sperm deep in the equine uterine horn allows fewer sperm to be inseminated while maintaining acceptable fertility, and has been promoted for use in circumstances when fertility would be expected to be low if standard insemination were used (e.g., semen from a subfertile stallion, or frozen-thawed semen). Two main techniques, transrectally guided (TRG) and hysteroscopic (HYS) insemination, have been developed for this purpose; however, there is some controversy regarding their comparative efficacy. This study was conducted to compare pregnancy rates when mares were inseminated by T...
Two hundred three cases of equine lymphoma classified according to the World Health Organization (WHO) classification criteria. Lymphoma is the most common malignant neoplasm in the horse. Single case reports and small retrospective studies of equine lymphomas are reported infrequently in the literature. A wide range of clinical presentations, tumor subtypes, and outcomes have been described, and the diversity of the results demonstrates the need to better define lymphomas in horses. As part of an initiative of the Veterinary Cooperative Oncology Group, 203 cases of equine lymphoma have been gathered from 8 institutions. Hematoxylin and eosin slides from each case were reviewed and 187 cases were immunophenotyped and c...
In vitro biomechanical evaluation and comparison of a new prototype locking plate and a limited-contact self compression plate for equine fracture repair. To determine if the mechanical properties (strength and stiffness) of a new prototype 4.5 mm broad locking plate (NP-LP) are comparable with those of a traditional 4.5 mm broad limited-contact self compression plate (LC-SCP), and to compare the bending and torsional properties of the NP-LP and LC-SCP when used in osteotomized equine third metacarpal bones (MC3). Methods: The plates alone were tested in four-point bending single cycle to failure. The MC3-plate constructs were created with mid-diaphyseal osteotomies with a 1 cm gap. Constructs were tested in four-point bending single cycle to fa...
[Seasonal and national differences in the selenium supply of horses across Europe]. Evaluation of the differences in the selenium supply to horses across Europe. Methods: Serum samples from 137,152 horses all over Europe, which had been sent by veterinarians to IDEXX Vet Med Labor between January 1st 2006 and December 31st 2011, were routinely analyzed for the selenium concentration by means of ICP-analytic. Results: The selenium content of the soil appears to play a key role in the selenium supply to horses. Countries closer to the ocean provided a better selenium supply than countries in central Europe. The best selenium supply can be seen in Denmark and in the Netherlands....
[Antioxidant properties of proteins after freezing-thawing]. Experimental data are presented which were obtained under comparative evaluation of influence of different freezing-thawing conditions on antioxidant properties of isolated proteins: human serum albumin, cytochrome c from the horse heart and glucose oxidase from Aspergillus niger. The observed protein antioxidant activity alterations are assumed to be a result of protein conformational changes. The character of freezing-thawing influence on the protein antioxidant activity depends on the molecular structure and cooling conditions.
Correlation of serum IgG concentration in foals and refractometry index of the dam’s pre- and post-parturient colostrums: an assessment for failure of passive transfer in foals. The object of this study was to evaluate the usefulness of measuring the differences in the values of the serum total protein (DVSTP) concentration of foals and the refractometry index (DVRI) of the milk of dams before and after nursing of the colostrum for assessing failure of passive transfer (FPT) in foals. Serum samples from 31 foals were collected before the first nursing and other 1 to 6 times between 4 and 24 hr after birth. Paired colostrum and milk samples were collected from 14 of their dams at the same time. Serum samples were analyzed for IgG concentration using a single radial imm...
Only falls and horses: accidents and injuries in racehorse training. The horseracing training industry has largely been ignored in terms of active occupational health research. Objective: To provide baseline statistics on the specific nature and type of accidents that occurred in English horseracing stables during 2008. Methods: All 716 training yards/stables registered with the British Horseracing Authority were contacted in April/May 2009 to complete the Racing Injury Accident Statistical Survey. The survey asked respondents to detail all recorded accidents and injuries during 2008. Results: Two hundred and fifty-six yards (36%) provided usable responses. The...
Scanning electron microscopy and microbiological evaluation of equine burn wound repair after platelet-rich plasma gel treatment. Deep second-degree burns (DSDb) involve all epidermis layers, including the basal laminae. In general, DSDb heals with extensive areas of scarring. Platelet-rich plasma (PRP) is a source of growth factors, obtained by centrifugation and addition of thrombin and calcium, resulting in a gel. The objective of this study was to monitor the healing of DSDb by sequential biopsies after PRP treatment and evaluating by a scanning electron microscopy. Also, characterize bacterial profile and PRP antibacterial effect in horses' burns. Four horses were placed into two groups, G1 and G2, with the groups r...
Myenteric ganglionitis as a cause of recurrent colic in an adult horse. A 10-year-old Lipizzaner stallion was evaluated over the course of 1.5 years because of intermittent, recurrent colic. Results: The horse was initially treated medically for gastric ulcers; dietary changes were made, and a deworming protocol was instituted, without resolution of colic episodes. Subsequently, the horse underwent exploratory celiotomy and a large colon volvulus was identified with diffuse colonic wall thickening. A pelvic flexure biopsy sample was submitted for histologic examination, which revealed lymphocytic (CD3-positive T cells) myenteric ganglionitis (MG). The horse develo...
Impact of moderate exercise on ovarian blood flow and early embryonic outcomes in mares. The advent of embryo transfer has allowed horses to continue to train and compete during the breeding season. However, the associated stress of exercise may be detrimental to reproduction. The objectives of this study were to evaluate differing exercise protocols on reproductive blood flow and embryonic outcomes in mares. Light-horse mares were randomized into control (n = 4), partial-exercised (n = 6), and full-exercised (n = 6) groups. Partial-exercised mares were moderately exercised 30 min daily during the periovulatory period and rested after ovulation for 7 d. Full-exercised mares were e...
Blastomycotic osteomyelitis associated with severe lameness in a horse. A 12-year-old Quarter horse gelding was presented for evaluation of severe right forelimb lameness, 2 draining tracts over the lateral aspect of the right proximal antebrachium, and weight loss. A presumptive diagnosis of blastomycotic osteomyelitis was established based on radiographs and cytology of the exudate. This diagnosis was confirmed at necropsy. Un hongre Quarter horse âgé de 12 ans a été présenté avec une boiterie grave du membre antérieur droit, 2 faisceaux de drainage sur l’aspect latéral de l’avant-bras droit proximal et une perte de poids. Un diagnostic par infér...
Tendon structure changes after maximal exercise in the Thoroughbred horse: use of ultrasound tissue characterisation to detect in vivo tendon response. Investigations into the response of the superficial digital flexor tendon (SDFT) of the Thoroughbred horse to mechanical stimuli have been limited to in vitro cell culture studies focused primarily on gene expression of critical matrix proteins. It is uncertain how well in vitro outcomes translate to the tendon of the horse during exercise. The current study examined changes in tendon structure in response to maximal exercise using ultrasound tissue characterisation (UTC) to scan the SDFT prior to and after competitive racing. UTC uses contiguous transverse ultrasound images to assess the dyna...
Cardiac changes in horses with atypical myopathy. Atypical myopathy (AM) is an acute, fatal rhabdomyolysis in grazing horses that mainly affects skeletal muscles. Postmortem examinations have shown that myocardial damage also occurs. Limited information is available on the effect of AM on cardiac function in affected and surviving horses. Objective: To describe electrocardiographic and echocardiographic changes associated with AM in the acute stage of the disease and after follow-up. Methods: Horses (n = 12) diagnosed with AM in which cardiac ultrasound examination and ECG recording were available. Methods: All horses underwent clinical exami...
The equine practitioner-farrier relationship: building a partnership. The importance of hoof care in maintaining the health and soundness of a horse cannot be overstated. The aphorism, “No foot, no horse” still holds true. For equine ambulatory practitioners, the time devoted to a thorough understanding of the equine digit and it’s care is well worth the investment. The effort devoted to developing good relationships with individuals who will likely be responsible for implementing the changes suggested as a result of that understanding will be rewarded many times over in the course of the equine ambulatory practitioner’s career.
Prepurchase examination in ambulatory equine practice. Prepurchase examination provides a significant opportunity for veterinarians to offer an important professional service to the equine industry. When the service is performed competently and ethically, prospective buyers and sellers will recommend the examining veterinarian to fellow horse owners and professionals. To become comfortable with and skilled at performing prepurchase examinations, a veterinarian must understand the operational challenges associated with this service-and master them. Veterinarians performing prepurchase examinations should address the needs and manage the expectation...
Phacoemulsification and +14 diopter intraocular lens placement in a Saddlebred foal. A 2-month-old, 110-kg Saddlebred filly presented for evaluation of bilateral cataracts. A hypermature cataract in the left eye (OS) and an incipient nuclear cataract in the right eye (OD) were diagnosed. Electroretinography and ocular ultrasound revealed no contraindications for surgical removal of the cataractous lens OS. Phacoemulsification and implantation of a +14 diopter (D) intraocular lens (IOL) OS were performed at 4 months of age without complication, with the exception of a partial iridectomy performed on a small iris section that prolapsed through the corneal incision. Complete opht...
