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.
Post traumatic keratouveitis in horses. Traumatic keratouveitis in horses is characterised by a unilateral, aseptic, vascularising keratitis accompanied by moderate to severe anterior uveitis. In a series of 9 cases of post traumatic keratouveitis, topical and systemic nonsteroidal drugs and atropine were used to control the anterior uveitis while allowing spontaneous corneal healing. Among the 9 cases reported, 6 affected eyes previously treated with local corticosteroids took significantly longer to resolve when compared to 3 eyes in which corticosteroids had not been administered. It was concluded that, in cases of equine post tr...
Stress fractures of the vertebral lamina and pelvis in Thoroughbred racehorses. Thirty-six Thoroughbred racehorses that died at California racetracks between October 1993 and July 1994 were evaluated for stress fractures in the caudal portion of the thoracic and lumbosacral regions of the spine and the pelvis. The lumbosacral spine and pelvis were collected, debrided of soft tissues and examined visually for the presence of an incomplete fracture line and focal periosteal proliferation, characteristic of a stress fracture. Sixty-one per cent of specimens had evidence of stress fracture in the caudal portion of the thoracic and lumbosacral regions of the spine and the pelv...
Prevalence and characteristics of foal rejection in Arabian mares. Separate surveys of Thoroughbred, Paint, and Arabian mare owners revealed a higher than expected rate of foal rejection in Arabian mares. A behavioural history form was submitted by owners of foal rejecting and nonrejecting Arabian mares, and maternal behaviour and management practices compared. Four generation pedigrees of rejecting and nonrejecting Arabian mares were also examined. Foal rejecting mares were more likely to avoid, threaten, squeal at, chase, bite, and kick their foals post partum than nonrejecting mares. Nonrejecting mares were more likely to lick, nicker and defend their foal...
[Prevalence of infections caused by Salmonella spp. in cattle and horses at the Veterinary Teaching Hospital of the Faculty of Veterinary Medicine of the University of Montreal]. Bacteriologic detection of Salmonella spp. from feces of animals admitted to Veterinary Teaching Hospital of the Faculty of Veterinary Medicine, University of Montréal, in Saint-Hyacinthe was carried out during a 1-year period to estimate the prevalence of bovine and equine salmonellosis. Prevalence at the time of hospitalization was quite low: 1.4% in cattle and 1.7% in horses. Incidence was 15.1 cases/100 animal/year in cattle and 38.7 cases/100 animal/year in horses. Serotype typhimurium was the most prevalent in both species. In cattle, cases were evenly distributed over the year. In hors...
Repair of complete dorsal fracture of the proximal phalanx in two horses. Simple complete dorsal fractures of the proximal phalanx were repaired in 2 mature pleasure horses with cortical bone screws placed in lag fashion. Healing occurred within 12 weeks and both horses returned to their previous performance level of light pleasure riding within 6 months of injury.
Complications of balloon catheterization associated with aberrant cerebral arterial anatomy in a horse with guttural pouch mycosis. A 3-year-old Quarter Horse gelding was treated for left guttural pouch mycosis by ligation and balloon catheterization of the left internal carotid artery. Catheter advancement was shorter (10 cm) than the normally reported distance (13-15 cm), but was observed endoscopically during placement as it coursed within the internal carotid artery through the guttural pouch. The horse developed a persistently abnormal respiratory pattern after catheter placement, failed to gain consciousness, developed pulmonary edema, and died 5.5 hours postoperatively. Postmortem examination revealed an aberrant le...
Human onychomycosis caused by Trichophyton equinum transmitted from a racehorse. We report fingernail onychomycosis caused by Trichophyton equinum in a farmer who breeds racehorses. In addition to the thumbnail, T. equinum had infected one of the racehorses. Oral terbinafine cured the infection in the farmer.
Medical management of urinary calculi in a stallion with breeding dysfunction. A 9-year-old Thoroughbred stallion was examined because of breeding dysfunction and possible urethritis. The stallion had good libido and readily obtained an erection, mounted, and intromitted but did not thrust and ejaculate. After mounting the mare, the stallion would squeal and dismount. Endoscopic examination of the urethra and bladder revealed irregular, spiculate yellow crystals (< 1 cm in size) and sabulous deposits; numerous calculi were embedded in the mucosa of the bladder. Because the horse was at the start of a breeding season, the owner would not give permission for general anesth...
Complete fractures of the third metacarpal or metatarsal bone in horses: 25 cases (1980-1996). To compare treatments of complete fractures of the third metacarpal (MC) or metatarsal (MT) bone in horses and to identify factors that could impact prognosis. Methods: Retrospective case series. Methods: 25 horses with fractures of the third MC or MT bone that were treated by use of internal fixation, external coaptation, or both. Methods: Medical records from the Veterinary Medical Data Base of horses treated for fractures of third MC or MT bone at Texas A&M University from 1980 to 1994 and Purdue University from 1980 to 1996 were reviewed. Information on signalment, results of physical ...
Dental disease in geriatric horses. The dental management of geriatric horses can be a rewarding challenge to the practitioner. Owners become dissatisfied when their expectations are unrealistic. Consequently, communication between the owner and the practitioner is essential prior to the start of any dental procedure in a geriatric horse. Owners often expect the practitioner to correct what has been neglected for years. It is critical that the owner understand the possible complications associated with dental procedures and that some procedures (e.g., trephination) may necessitate protracted care. Often, when a tooth has been re...
Dental imaging. Radiography continues to be the initial test of choice in equine dental imaging for reasons of availability and ability to detect bone and tooth changes. Contrast radiography may be useful to characterize dental involvement in cases with draining tracts. For radiographically occult lesions, other modalities are useful. CT is better than plain radiography due to the inherent avoidance of superimposition of the opposite dental arcade, excellent bone density characterization, and good spatial resolution. Nuclear medicine may be useful to verify bone involvement in the dental region in cases in wh...
Pathophysiology of acquired dental diseases of the horse. Periodontitis, infundibular necrosis, and periapical infection are dental diseases commonly affecting adult horses. Routine dental examinations and care may help to prevent these diseases. Further investigation of the treatment of horses with these diseases using local antimicrobial therapy, restorative dentistry, and endodontic therapy is needed. An understanding of the pathogenesis of these diseases aids in diagnosis and treatment. Gingival hyperplasia and odontogenic tumors are uncommon but should remain in a list of differential diagnoses when examining a horse with pertinent clinical sign...
Dental physical examination. The objectives of the equine dental physical examination are to detect and quantify oral and dental disorders, to propose and carry out their treatment, and to implement management programs. The veterinarian should be able to offer a prognosis and to detail any future treatment or management plans that may be required. These objectives should take into account the cost of these procedures, and the veterinarian should be prepared to offer a cost-benefit analysis of the problem and the proposed cures.
Dental embryology, anatomy, development, and aging. Equine practitioners should be knowledgeable of dental anatomy and development to enhance their skill of age estimation of horses. The permanent teeth of horses are continually undergoing changes in shape and appearance. These changes may be used to suggest a reasonable age range for a horse.
Dental surgery in horses. Dental surgery is most often directed at removal of diseased or injured teeth by the least invasive method possible. Some procedures available can preserve traumatized or infected teeth. Complications of dental surgery are well documented and often encountered by veterinary surgeons. Principles of debridement, curettage, lavage and ventral drainage combined with appropriate medicinal management can reduce complications and lead to successful outcome after dental surgery.
Dental care and instrumentation. Equine dentistry is not just carpentry work that involves floating the sharp enamel points off cheek teeth. Although floating is the most common and essential part of equine dentistry, every horse deserves a complete veterinary dental examination on a regular basis. Without such an examination, the equine practitioner can not determine the corrective procedures needed inside the horse's mouth. Dentistry for all ages is covered. Necessary instruments for a complete oral examination are also discussed.
Dental corrective procedures. This article explains what is needed for successful extraction of diseased cheek teeth and how to realign the occlusal surface. Incisor teeth procedures and correcting abnormalities of cheek tooth crown wear are also discussed along with wolf and floating teeth.
Congenital dental disease of horses. Equine congenital dental deformities are not limited merely to those presented here; however, the examples discussed offer the reader an appreciation for the range of severity and complexity that may be found in affected horses. The veterinarian is obligated to provide the best possible care for the patient and to relieve animal suffering. The lack of definitive evidence for heritability of many of these defects can place the veterinarian in an untenable position, particularly when presented with literature that proclaims or suggests without evidence that a particular condition is inherited. I...
Traumatic dental disease and soft tissue injuries of the oral cavity. Trauma to the oral cavity can result in an array of injuries affecting teeth, bone, and soft tissue. A thorough examination of the oral cavity is often facilitated by employing a full-mouth speculum after the horse has been tranquilized. Identification of broken, loose, or split teeth; fractures of the premaxilla or mandible; and avulsion or laceration of soft tissue structures such as the lips or tongue is usually straightforward. Treatment options vary depending on the structure involved; however, appropriate treatment generally results in a functional and cosmetically acceptable end result....
Controlled-release products for the control of the estrus cycle in cattle, sheep, goats, deer, pigs, and horses. This paper describes the estrus cycles of a number of livestock breeds and reviews the controlled-release drug delivery systems that are currently available for the purpose of controlled breeding. The bovine estrus cycle is reviewed in detail, and the estrus cycles of other species are described in a manner that highlights similarities and differences between species. Pertinent formulation and pharmacokinetic information about current drug delivery systems is presented and discussed, and recent advances in this area are also described.
Effect of three types of half-limb casts on in vitro bone strain recorded from the third metacarpal bone and proximal phalanx in equine cadaver limbs. To determine effect of 3 half-limb casts on bone strains recorded from the proximal phalanx (P-1) and third metacarpal bone (MCIII) of equine cadaver limbs, using a mechanical testing machine. Methods: 12 equine cadaver limbs and 4 live horses. Methods: Bone strains were recorded at middorsal P-1 and the dorsal cortical aspect of the distal third of MCIII while limbs were variably loaded with 100 to 1,000 lb of force. To determine ability of the cast to protect the distal portion of the limb from weight-bearing loads, strains were recorded with the limb in 1 of the 3 casts and with it unsuppor...
Rabies prophylaxis following the feeding of a rabid pony. A survey was performed to identify people who were exposed to a rabid pony and determine whether or not they received rabies postexposure prophylaxis (PEP). Sixty-one visitors who came in contact with the rabid pony were identified. These visitors heard about the rabid pony via the news media. Forty-five visitors were exposed during the 2 weeks before the pony died. Thirty-two of these 45 visitors received PEP. Thirty-one visitors had or may have had saliva contact to an open wound or mucosa and all 31 received PEP. Fourteen visitors had no saliva contact to a wound or mucosa and one received ...
Blood-gas measurements adjusted for temperature at three sites during incremental exercise in the horse. Rectal temperature (Tre) is often used to adjust measurements of blood gases, but these adjusted measurements may not approximate temperatures during intense exercise at main sites of gas exchange: muscle and lung. To evaluate differences in blood gases between sites, temperatures (T) were measured with thermocouples in the rectum (re), in mixed venous blood (v), in gluteal muscle (mu), and on the skin (sk) in seven Arabian horses as they underwent an incremental exercise test on a treadmill. Blood samples were drawn from the carotid artery and pulmonary artery (mixed venous) 30 s before each ...
