Veterinary practice in relation to horses encompasses the medical care, management, and treatment of equine species. This field involves various aspects of equine health, including preventive care, diagnosis, and treatment of diseases, surgical interventions, and emergency care. Equine veterinarians employ a range of diagnostic tools and techniques such as physical examinations, imaging, and laboratory tests to assess and monitor horse health. In addition to addressing physical ailments, veterinary practice also includes nutritional management, reproductive health, and performance-related issues. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, advancements, and outcomes in veterinary practices specific to equine health.
Small intestinal strangulation caused by a mesodiverticular band and diverticulum on the mesenteric border of the small intestine in a horse. A 4-year-old Quarter horse stallion was presented for acute abdominal pain. Exploratory celiotomy revealed a mesenteric diverticulum of the jejunum and mesodiverticular band that were associated with small intestinal strangulation. Resection and anastomosis were performed. A second celiotomy was performed due to adhesions. The horse recovered completely and returned to training. Un étalon Quarter horse âgé de 4 ans a été présenté pour une douleur abdominale aiguë. Une laparatomie exploratoire a révélé un diverticule mésentérique du jéjunum et une bande mésodiverticulaire qui on...
Evaluation of a wireless ambulatory capsule (SmartPill®) to measure gastrointestinal tract pH, luminal pressure and temperature, and transit time in ponies. This study investigated the use of a wireless ambulatory capsule (WAC; SmartPill(®) pH.p GI Monitoring System) to determine WAC-gastric emptying time (GET) in ponies. Objective: To measure WAC-GET and compare it to those findings with GET assessed by nuclear scintigraphy (S-GET). Objective: WAC-GET will be slower than S-GET, but will be significantly correlated. Methods: Seven healthy adult mixed-breed pony mares were used in this study. Feed was withheld for 12 h prior to the WAC administration. After administration, a complete-feed diet was fed to allow the WAC to pass into the stomach. Lum...
Precision of a photogrammetric method to perform 3D wound measurements compared to standard 2D photographic techniques in the horse. Methods of 3D wound imaging in man play an important role in monitoring of healing and determination of the prognosis. Standard photographic assessments in equine wound management consist of 2D analyses, which provide little quantitative information on the wound bed. Objective: 3D imaging of equine wounds is feasible using principles of stereophotogrammetry. 3D measurements differ significantly and are more precise than results with standard 2D assessments. Methods: Repeated specialised photographic imaging of 4 clinical wounds left to heal by second intention was performed. The intraoperator ...
Effect of sedation with detomidine on intraocular pressure with and without topical anesthesia in clinically normal horses. To determine the effect of sedation with detomidine on intraocular pressure (IOP) in standing horses and whether topical ocular application of anesthetic alters this effect. Methods: Clinical trial. Methods: 15 clinically normal horses. Methods: Horses were assigned to group 1 (n = 7) or 2 (8). Intraocular pressure measurements were obtained at baseline (before sedation) and 10 minutes after IV administration of detomidine (0.02 mg/kg [0.009 mg/lb]). Group 1 horses had an additional IOP measurement at 20 minutes after sedation. For group 2 horses, topical ocular anesthetic was administered 10 ...
Semi-autonomous wheelchair developed using a unique camera system configuration biologically inspired by equine vision. This paper is concerned with the design and development of a semi-autonomous wheelchair system using cameras in a system configuration modeled on the vision system of a horse. This new camera configuration utilizes stereoscopic vision for 3-Dimensional (3D) depth perception and mapping ahead of the wheelchair, combined with a spherical camera system for 360-degrees of monocular vision. This unique combination allows for static components of an unknown environment to be mapped and any surrounding dynamic obstacles to be detected, during real-time autonomous navigation, minimizing blind-spots an...
A review of foal diarrhoea from birth to weaning. Diarrhoea is among the most common clinical complaints in foals. Aetiologies, diagnostic testing and recommended interventions for specific causes of enterocolitis are summarised. Many mild to moderately affected foals can be managed in an ambulatory setting, while others will benefit from more intensive care at a referral centre.
Essential considerations for equine oral examination, diagnosis, and treatment. Equine dentistry should no longer be thought of as art over science. To be an effective equine dental clinician requires considerable investment in knowledge beyond the basic veterinary degree. It requires current scientific dental knowledge and adherence to the fundamental principles of medicine, dentistry, and surgery. Knowledge and principles will provide clinicians with the necessary information to make more evidence-based decisions as the scientific literature continues to evolve. Diagnosis and therapy should be seen as journeys with a destination, keeping in mind the values of the Hippoc...
Increased adenosine concentration in bronchoalveolar lavage fluid of horses with lower airway inflammation. Several reports have suggested a role for adenosine in the pathogenesis of chronic airway conditions and this has led to new therapeutic strategies to limit airway inflammation. In this study, detectable levels of adenosine in bronchoalveolar lavage (BAL) samples from 11 horses with non-infectious lower-airway inflammation and 14 healthy controls are reported, with significantly higher values in horses with airway inflammation. Although these increased levels did not correlate with changes in neutrophil percentage in BAL, a positive association between adenosine levels and signs of lower airwa...
Three-dimensional ultrasound imaging of the equine fetus. The objective was to assess the optimal procedure for real-time, three-dimensional (3D) ultrasound (US) imaging for assessing the equine fetus during the first half of gestation and the possibility of using 3D US imaging of the equine fetus in clinical applications. Seventeen pregnant mares were examined by 3D US between Days 35 and 180 of gestation. Abdominal and endo-vaginal real-time 3D transducers used in human medicine were used for transrectal and transvaginal examinations, respectively. Images were recorded by both 3D stationary and real-time movies. In a comparison of four methods, tra...
Lactate production and measurement in critically ill horses. Blood lactate concentration can be easily measured by practitioners using inexpensive point-of-care meters. Anaerobic tissue metabolism resulting from inadequate oxygen delivery (DO2) is the most important cause of an increase in blood lactate concentration in equine patients. However,hyperlactatemia also occurs under conditions of apparently adequate DO2, usually in association with sepsis and an intense inflammatory reaction. Numerous mechanisms have been proposed for aerobic hyperlactatemia, including increased Na+/K+-ATPase activity in response to inflammatory mediators; inhibition of pyru...
[New drugs for horses and production animals in 2010]. In 2010, three new active pharmaceutical ingredients were released on the German market for horses and food-producing animals. These were gamithromycin (Zactran®), a new macrolide antibiotic, Monepantel (Zolvix®), a broad spectrum anthelmintic with a novel mechanism, and Pergolide (Prascend®), the first dopamine receptor agonist for animals. Two substances have been approved for additional species. The tetracycline antibiotic doxycycline is now also authorized for turkeys and the nonsteroidal anti-inflammatory drug firocoxib from the group of cyclo-oxygenase-2 (COX-2) inhibitors is now avai...
[Equine-assisted therapy in child psychiatry]. The use of a horse or pony as a therapeutic tool is often presented in the media as a recent phenomenon. A survey of 103 institutions shows that it is in fact an approach well rooted in child and adolescent psychiatry. However, professionals who use equine-assisted therapy are calling for an assessment to be carried out enabling them to hone their practices.

Post operative infection, pyrexia and perioperative antimicrobial drug use in surgical colic patients. Infections are common complications in post operative colic patients. It is the impression of some surgeons that pyrexia in the early post operative period is a sign of infection and appropriate timing of perioperative antimicrobials will decrease the incidence of post operative infection. Objective: To determine the association between 1) post operative pyrexia and development of infection and 2) perioperative antimicrobial drug use and infection rate in post operative colic patients. Methods: Medical records of patients undergoing surgical treatment for colic were reviewed. Horses recovering...
Nictitating membrane resection in the horse: a comparison of long-term outcomes using local vs. general anaesthesia. Neoplasia, for which surgical excision is a frequent treatment, is the most common disease of the equine nictitating membrane. There is little long-term follow-up information available to the practitioner regarding the long-term effects of nictitating membrane excision on ocular health. No information is available to compare recurrence of primary neoplasia of the nictitating membrane after excision with local or general anaesthesia. Objective: To evaluate the long-term complications of nictitating membrane resection in horses; recurrence of neoplasia of the nictitating membrane when nictitatin...
