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.
Multicentric T-cell lymphoma presenting as inferior palpebral swelling in a Standardbred mare. A 6-year-old Standardbred mare that presented with bilateral palpebral swelling and a left corneal ulcer was diagnosed with a multicentric T-cell lymphoma. Other clinical findings included submandibular lymphadenopathy and oedema, pharyngeal oedema and rhinitis. Prior to euthanasia the horse developed keratomalacia, the onset of which was coincidental with the use of high doses of topical and systemic corticosteroids. Although an unusual presentation, palpebral swelling should be considered as a clinical sign of lymphoma.
The effect of blood contamination on equine synovial fluid analysis. Based on a systemic complete blood count and a synovial fluid sample, to develop a mathematical model enabling the approximation of corrected values for synovial fluid white blood cell (WBC) count, neutrophil percentage, and total protein concentration in samples of synovial fluid that were contaminated by blood. Methods: Peripheral venous blood and synovial fluid samples were obtained from ten horses. A pooled synovial fluid sample from each horse was separated into 2 mL aliquots, which were subsequently contaminated with a known percentage of autogenous blood (0 to 50% of the synovial fluid ...
A review of equine laparoscopy. Minimally invasive surgery in the human was first identified in mid 900's. The procedure as is more commonly practiced now was first reported in 1912. There have been many advances and new techniques developed in the past 100 years. Equine laparoscopy, was first reported in the 1970's, and similarly has undergone much transformation in the last 40 years. It is now considered the standard of care in many surgical techniques such as cryptorchidectomy, ovariectomy, nephrosplenic space ablation, standing abdominal exploratory, and many other reproductive surgeries. This manuscript describes the hi...
Pneumocephalus in five horses. Pneumocephalus is occasionally encountered in horses but poorly described in the literature. The study aimed to describe historical, clinical and diagnostic imaging findings and outcome in horses to increase the awareness and recognition of the condition amongst equine practitioners, allowing appropriate management of these cases. Cases of pneumocephalus from 4 participating institutions were identified and case details extracted from the medical records. Five cases of pneumocephalus were identified. Head trauma with suspected or confirmed fractures of the sinuses was the underlying cause in 4...
Systemic or intrasynovial medication as singular or as combination treatment in horses with (peri-)synovial pain. Records of lame horses (2004-2007) with (peri-)synovial pain of the metacarpophalangeal joint (MCPJ, n = 53), digital flexor tendon sheath (DFTS, n = 20), and distal interphalangeal joint (DIPJ, n = 31) were evaluated (n = 104). Cases were grouped according to the following treatments: (1) systemic administration of NSAIDs (n = 40); (2) intrasynovial administration of glucocorticosteroids (n = 30); (3) combination treatment (n = 34). Outcome was defined as successful when the owner reported that the horse had returned to its previous level of performance within a period of up to six months aft...
Toe modifications in hind feet shoes optimise hoof-unrollment in sound Warmblood horses at trot. It was shown that rolled-toe shoes smooth hoof-unrollment and thereby reduce peak loading of forelimbs in trotting Warmblood horses. Shoe design and shoeing technique for hind feet have been modified over recent decades from fully fitted, toe-clipped shoes to set-back, side-clipped shoes. Objective: To study the effects of different shoe modifications on loading and movement of the hind hoof. Methods: Ten clinically sound Warmblood horses were shod with 3 types of hind shoe: first, fully fitted, toe-clipped shoes, followed randomly by side-clipped shoes without a rolled toe that were set back ...
The effect of radio electric asymmetric conveyer treatment on sperm parameters of subfertile stallions: a pilot study. The Radio Electric Asymmetric Conveyer (REAC) has been mostly applied to treat symptoms related to psychological stress. In the study, we demonstrated the effect of REAC-Veterinary Neuro Psycho Physical Optimization (VNPPO) treatment protocol on sperm parameters of subfertile (n=11) and fertile (n=4) stallions. Subfertile stallions showed a reduced sperm concentration, progressive motility and normal morphology compared to fertile stallions. An increase in progressive sperm motility and quality of sperm morphology was found in subfertile stallions after the REAC-VNPPO treatment. The positive e...
[Successful treatment of an equine sarcoid. Case report on a combined surgical and photodynamic therapy]. The case report describes the surgical and photodynamic treatment (PDT) of an equine sarcoid in a 6-year-old gelding. A mass on the ventral prepuce, several tumours on the lateral aspect of the prepuce and one sarcoid on the front aspect of the chest were treated. For PDT, Temoporfin (Fospeg® Biolitec AG, Jena) at a concentration of 0.15mg/ml was injected locally. The subsequent irradiation was performed using a red-light laser (652nm) with an energy density of 10J/cm². The mass on the ventral aspect of the prepuce and some of the lateral tumours displayed total remission. The remaining tumo...
[New drugs for horses and production animals in 2011]. In 2011, three newly developed active pharmaceutical ingredients for horses and food producing animals were released on the German market for veterinary drug products. Two of these new products represent different drug classes of antibiotics, the polypeptide antibiotic Bacitracin (Bacivet™) and the macrolide antibiotic Clorsulon (Levatum®). The third product represents an anticestodal antiparasitic (Tildipirosin, Zuprevo®). Furthermore, three established veterinary active pharmaceutical ingredients were modified to allow their application for additional species. Thus the nonsteroidal anti-...
Equine cellular therapy–from stall to bench to bedside? Pioneering clinical stem cell research is being performed in the horse, a recipient of cutting edge veterinary medicine as well as a unique animal model, paving the way for human medical applications. Although demonstrable progress has been made on the clinical front, in vitro characterization of equine stem cells is still in comparatively early stages. To translate the promising results of clinical stem cell therapy in the horse, advances must be made in the characterization of equine stem cells. Aiming to improve communication between veterinarians and other natural scientists, this review g...
Advances in nuclear medicine. Nuclear scintigraphy is a mainstay of diagnostic imaging and has preserved its relevance in the imaging of acute and chronic trauma. It is particularly useful in the evaluation of athletic injuries. Pitfalls of interpretation, false negatives and false positives exist as with many imaging modalities. Synthesis of physical exam findings, lameness evaluation and, when possible, diagnostic analgesia in combination with nuclear scintigraphy imaging findings, will allow for the most information to be applied to the patient's clinical problem.
Treponemes-infected canker in a Japanese racehorse: efficacy of maggot debridement therapy. A 3-year-old thoroughbred colt presented with canker on its left hind foot. Subsequent development of cottage cheese-like horns and dermatitis disturbed healing, despite the use of miscellaneous orthodox treatment approaches to the lesions. Histological examination revealed exudative and suppurative dermatitis, and proliferatively suppurative epidermitis infected with helically coiled treponemes. Total debridement under general anesthesia led to a temporary improvement, but the ground surface regenerated abnormal epidermis similar to that observed initially after surgery. Maggot debridement th...
Digital radiography for the equine practitioner: basic principles and recent advances. As availability increases and cost decreases, digital radiograph systems become more common in equine practice. Technological advances provide an array of choices for the equine practitioner considering purchase. Two classes of systems are available: computed radiography and flat-panel systems (direct radiography). Image processing encompasses all manipulations performed on an image at acquisition and can have a profound effect on the final digital radiograph. Consideration should be given to the type of display monitor because many options are now available. The type of display monitor and th...
Tenogenic differentiation of equine mesenchymal progenitor cells under indirect co-culture. Adult bone marrow mesenchymal stem cells (BM-MSCs) are a potential cell source for tendon repair in direct cell therapy and tissue engineering investigations. The purpose of this study was to evaluate the tenogenic induction of undifferentiated BM-MSCs under indirect co-culture technique with trimmed native tendon tissue. Since the horse represents a preferred species to study tendon regenerative strategies, this work was conducted on equine BM-MSCs. Methods: Equine BM-MSCs were co-cultured in a transwell system with tendon tissue fragments. The BM-MSC tenogenic differentiation was evaluated b...

The objective of this study was to assess the pharmacokinetic profile and determine whether any adverse effects would occur in seven healthy adult horses following oral meloxicam tablet administration once daily for 14 days at a dose of 0.6 mg/kg·bwt. Horses were evaluated for health using physical examination, complete blood count, serum chemistry, urinalysis, and gastroscopy at the beginning and end of the study. Blood was collected for the quantification of meloxicam concentrations with liquid chromatography and mass spectrometry. The mean terminal half-life was 4.99 ± 1.11 h. There was n...
Blue light from light-emitting diodes directed at a single eye elicits a dose-dependent suppression of melatonin in horses. The production of melatonin during night-time hours decodes day length for seasonally breeding animals. The use of artificial light to advance the breeding season in mares is common practice within the equine industry. Four healthy Thoroughbred mares were used to evaluate the minimum intensity of light required to inhibit serum melatonin. Mares were fitted with indwelling jugular catheters and using a crossover design blood samples were collected following 1h exposure to light (barn lighting approximately 200 lux), dark (<0.1 lux), and 3, 10, 50, and 100 lux intensities. The light source wa...
Light microscopic evaluation and scanning electron microscopic analysis of horse eyes following deep anterior lamellar keratectomy.

Bilateral parotid duct transposition for keratoconjunctivitis sicca in a Connemara stallion. A 7-year-old Connemara stallion was presented with a 4 month history of blepharospasm, recurrent corneal ulcerations, mucopurulent ocular discharge, and keratoconjunctivitis sicca (KCS) in both eyes unresponsive to medical therapy. Ophthalmic examination revealed lackluster corneas, axial corneal scarring and pigmentation with associated neovascularization, and absolute KCS in both eyes. Computed tomography scan and endoscopic evaluation of the upper airway and guttural pouches revealed no structural abnormalities to indicate neurogenic KCS. The stallion was diagnosed with immune-mediated dacr...
64, XX, SRY-negative, testicular DSD syndrome in a Lusitano horse. Here is reported a disorder of sex development found in the Portuguese Lusitano horse breed. The complex genital phenotype included mammary glands, abdominal testes without epididymis, connected through oviducts to pelvic hypoplastic uterine horns and fused vulvar labia majora from which protruded ventrally a penis-like structure. This structure was presented in a reversed position, the urethral opening placed dorsally in the glans. However, it was functional both for micturition and erection. The horse exhibited female micturition posture and aggressive male-like behaviour, including flehmen,...
Advances in equine ultrasonography. The many advancements in ultrasound technology, including spatial compounding, harmonic imaging, multidimensional and extended field-of-view images, and improvements in transducer capabilities, are used to enhance the ultrasonographic examination of the equine patient. The improvements in software and hardware capabilities help overcome artifacts, improve image quality, and allow better documentation of the examination for follow-up studies. In addition, the ability of smaller, more portable machines to produce better images is ideal for the ambulatory practice setting.
Case series of equine pituitary pars intermedia dysfunction in a tropical climate. The clinical manifestations of equine pituitary pars intermedia dysfunction (PPID) in temperate climates are well described. The classic presentation is that of an older animal with hirsutism, laminitis, poor muscle tone, pendulous abdomen and weight loss. This case series highlights the additional clinical signs of anhidrosis and heat stress with secondary exercise intolerance that were seen as primary presenting problems in equids with PPID in the hot, humid conditions of a tropical climate. The clinical signs resolved with medical treatment for PPID.
