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.
Debridement of septic physeal lesions in 3 foals. Radiographically, osteolysis of the physis consistent with a septic physitis was observed in 3 foals. The foals were treated with surgical debridement and antimicrobials. Two of the horses were sound for use as adults; the third was euthanatized due to concurrent infectious arthritis and septicemia.
Leiomyosarcoma of the duodenum in two horses. Two horses affected by chronic, intermittent colic were found, at post-mortem examination, to have localized annular thickening of a segment of the duodenum. Histological examination of the lesion in both cases revealed a tumour composed of bundles of oval or spindle-shaped cells that stained as muscle with van Gieson stain. The histological diagnosis was leiomyosarcoma. The tumour had caused partial bowel obstruction in both horses.
The isoelectric focusing properties of serum alkaline phosphatase in disease and following prednisolone and phenylbutazone administration in the horse. This study was undertaken to ascertain if the isoelectric focusing pattern of serum alkaline phosphatase (AP) from sick horses with high activity is useful for determining its tissue origin. The effect of oral prednisolone and phenylbutazone therapy on this enzyme in healthy horses was also investigated. The sick horses were divided into three groups: hepatic, intestinal and miscellaneous. All sera had approximately thirteen bands of AP activity when focused on agarose gels with a pH gradient of 3.5 to 9.5. All the horses in the liver disease group had greater than 65% of enzyme activity in ba...
Common injuries in horseback riding. A review. The most common location of horse-related injuries is the upper extremity (24% to 61%) with injuries to the lower extremity second in frequency (36% to 40%). The head and face sustain 20% of horse-related injuries. The most common type of injury is a soft tissue injury (92% to 1%), followed by a fracture (57% to 3%). Concussion is the third most common type of injury (63% to 2%). The most frequent cause of hospitalisation is concussion (38% to 4%) with fracture second. The most common injury which leaves residual impairment is injury to the central nervous system. The age at which most injury ...
Equine infectious anemia: prospects for control. Equine infectious anemia has been managed in most countries by the imposition of testing and quarantine regulations. In the United States, about 700,000 of the more than 7,000,000 horses are tested annually. As long as the status of greater than 90% of the horse population remains unknown and horses are transported and congregate in a relatively unrestricted manner, EIA will continue to exact its toll. Therefore, it is incumbent on the scientific community to continue to develop and refine practical and sensitive diagnostic tests for EIA which will be used in an expanding market, to reduce the...
Historical highlights in cardiac pacing. The benchmarks in cardiac pacing are identified, beginning with F. Steiner (1871), who rhythmically stimulated the chloroform-arrested hearts of 3 horses, 1 donkey, 10 dogs, 14 cats, and 8 rabbits. The chloroform-arrested heart in human subjects was paced by T. Greene in the following year (1872) in the UK. In 1882, H. Ziemssen in Germany applied cardiac pacing to a 42-year old woman who had a large defect in the anterior left chest wall subsequent to resection of an enchondroma. Intentional cardiac pacing did not occur until 1932, when A.A. Hyman in the US demonstrated that cardiac pacing cou...
Temperature sensitivity of equine herpesvirus isolates: a brief review. This article reviews the findings on temperature sensitivity of equine herpesvirus isolates with an emphasis on equine herpesvirus 3, etiological agent of equine coital exanthema. The hypothesis is presented that the relative apathogenic nature of this herpesvirus may be an indirect result of its inability to synthesize and/or process glycoproteins needed by the virus to produce infectious virions at the normal body temperature of its natural host. It is suggested that equine herpesvirus 3 is the more evolved and naturally attenuated member of the equine herpesviruses.
Ileocecal intussusception in horses: 26 cases (1981-1988). The case records of 26 horses with ileocecal intussusception over a 7-year period were reviewed to determine clinical features of the disease and response to treatment. The median age of horses with ileocecal intussusception was 1 year and ranged from 2 weeks to 19 years. There was no apparent gender or breed predisposition to this disease. An acute form of ileocecal intussusception was diagnosed in 19 horses with signs of moderate to severe abdominal pain of less than or equal to 24 hours' duration, and a chronic form was diagnosed in 7 horses with signs of intermittent, mild to moderate abdo...
[Heteroimmune hemolytic anemia associated with antilymphocyte globulin treatment in a patient with aplastic anemia]. A 24-year-old male patient with a severe aplastic anemia (SAA) was treated with equine-antilymphocyte globulin (ALG). As complication of this treatment he developed a severe heteroimmune hemolytic anemia mediated by anti-species pan-agglutinin antibodies present in ALG. In spite of the fact that ALG is absorbed with red-cell stroma and platelets to remove anti-erythrocyte and anti-platelet contaminating antibodies, often only partial absorption is achieved, and the remaining antibodies are passively acquired by the recipient. Neutropenia and especially thrombocytopenia are usual complications ...
Prevalence of gastric lesions in foals without signs of gastric disease: an endoscopic survey. Gastroendoscopic examinations were conducted on 75 Thoroughbred foals aged two to 85 days on seven breeding farms in England and Ireland. The foals showed no signs of gastric disease. There was no significant difference between lesion prevalence in foals in England (16 of 28 foals; 57 per cent) or Ireland (22 of 47 foals; 47 per cent). Neither was there any sex predilection (18 of 36 males; 20 of 39 females). Lesions were most prevalent in foals under 10 days old (8 of 9) and least prevalent in foals older than 70 days (3 of 10). Lesions occurred most frequently in the squamous mucosa immediat...
Different types of inguinal herniation in two stallions and a gelding. Three horses with different and unusual types of inguinal herniation outside the vaginal cavity are described in detail. Attention is paid to the differences between these conditions and the more commonly occurring inguinal herniation inside the vaginal cavity.
Disseminated coccidioidomycosis in a horse with osteomyelitis. Coccidioidal osteomyelitis was diagnosed in a horse after a 6-month period of coughing, weight loss, and lameness. The horse was euthanatized and the diagnosis was confirmed by gross and microscopic findings.
[Intersexuality in domestic mammals]. With the exception of bovine freemartinism, intersexuality is rarely reported in domestic animals. The few cases of intersexuality reported here in dogs, cattle, goats, sheep and horses were classified according to the karyotype. The XX intersexes described here included goats which were either polled male pseudohermaphrodites or true hermaphrodites and dogs which were female pseudohermaphrodites. Among the XY intersexes studied, one dog was a true hermaphrodite, whereas the others were male pseudohermaphrodites, all mares showed gonadal dysgenesis and one cow was a female pseudohermaphrodite....
High-performance liquid chromatography/tandem mass spectrometry: its use for the identification of stanozolol and its major metabolites in human and equine urine. A screening procedure for the anabolic steroid stanozolol in human and equine urine was developed based on enzymatic hydrolysis, liquid-liquid extraction and reversed-phase liquid chromatography combined on-line with tandem mass spectrometry. The column effluent was introduced into the atmospheric pressure ionization source of a triple-quadrupole mass spectrometer via a heated pneumatic nebulizer liquid chromatograph/mass spectrometer interface. Abundant protonated molecular ions were generated by corona discharge ionization. Confirmation of stanozolol and several of its hydroxylated and dihyd...
Effect of GnRH treatment during the anovulatory season on multiple ovulation rate and on follicular development during the ensuing pregnancy in mares. Seasonally anovulatory mares were injected, i.m., twice daily with a GnRH analogue (GnRH-A), and hCG was given when the largest follicle reached 35 mm in diameter. In Exp. 1, treatment was initiated on 23 December when the largest follicle per mare was less than or equal to 17 mm. An ovulatory response (ovulation within 21 days) occurred in 17 of 30 (57%) GnRH-A-treated mares on a mean of 15.8 days. The shortest interval to ovulation in control mares (N = 10) was 57 days. The diameter of the largest follicle first increased significantly 6 days after start of treatment. In Exp. 2, treatment wa...
[Experiences with the QBC-V hematology system at the veterinary hospitals of Zurich and Bern]. The QBC V hematology system was tested with respect to its application in veterinary medicine. PCV's and counts of total leukocytes, granulocytes, lympho/monocytes and platelets collected from 435 horses, dogs and cats were determined and compared with conventionally measured values. Precision and accuracy were found to be good for the majority of parameters. In the authors' opinion the QBC V hematology system is well suited for use in veterinary practice.
The use of long-acting neuroleptics, perphenazine enanthate and pipothiazine palmitate in two horses. Two Arabian horse stallions with behavioural problems were treated with long-acting neuroleptics in order to facilitate corrective training. Perphenazine enanthate, administered intramuscularly at a dose of 0.5 mg kg-1 had an effect for 30 d. Pipothiazine palmitate (1 mg kg-1) induced tranquilization of 30 d duration as well as extra-pyramidal clinical signs, ataxia and aphagia. Neither horse showed prolapse of the penis or haemolysis.
Effects of atracurium administered by continuous intravenous infusion in halothane-anesthetized horses. Atracurium (0.4 mg/ml in isotonic NaCl solution) was administered by IV infusion to 7 healthy adult horses for 2 hours. Over the 2-hour period, a 95 to 99% reduction of train-of-four hoof-twitch response was maintained by 0.17 +/- 0.01 mg of atracurium/kg of body weight/h, for a total of 161 +/- 6 mg of atracurium (mean +/- SEM) for horses 1 to 4, 6, and 7. Horse 5, a mare in estrus, required 0.49 mg of atracurium/kg/h to maintain comparable relaxation. Hoof-twitch recovery time from 10 to 75% of baseline strength was 19.8 +/- 2.5 minutes for all horses. The 10 to 75% recovery time for horse 5...
Equine coital exanthema (EHV-3 virus) infection in India. A progenital disease encountered at one equine stud farm at Bangalore in Southern India during 1987 was investigated and confirmed as equine coital exanthema on the basis of characteristic lesions and clinical symptoms, isolation of equine herpes virus-3 (EHV-3) from the scabs collected from animals having active lesions and demonstration of neutralizing antibodies in the sera of recovered mares and stallion. This is the first authenticated report of the occurrence of equine coital exanthema in India due to EHV-3.
Wounds of the esophagus and trachea. Wounds of the esophagus and trachea are uncommon, but closed wounds can be difficult to diagnose and treat. Esophageal wounds are the more serious and can be life-threatening; however, appropriate surgical and medical treatment applied without delay can be successful in some cases, especially in full-thickness longitudinal wounds. Tracheal wounds are usually less severe, but the high risk of iatrogenic injuries to the trachea should be recognized. Also, tracheal injuries can limit the athletic potential of a horse.
Equine bandaging techniques. Topical medications and bandages play an important role in the management of equine wounds. Certain water-soluble antibacterial ointments (povidone-iodine, polymixin-neosporin-bacitracin) may be appropriate for use on contaminated wounds. A well-designed equine bandage is usually composed of primary, secondary, and tertiary layers. Because so many different products are available, the practitioner is advised to become familiar with the handling characteristics of a few. Because of the irregular contours of the equine limb, only products that stretch and conform should be used. Bandages should ...
