Topic:Veterinary Care
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.
Pathology of equine phycomycosis. The pathological findings in three cases of equine phycomycosis in Costa Rica are described. Two cutaneous (Pythium sp) and one nasal lesion (Conidiobolus) were observed.
Segmental atresia of the transverse colon in a foal with concurrent equine herpes virus-1 infection. Segmental atresia of the transverse colon was observed at necropsy in a neonatal foal. The dorsal and ventral components of the large colon were fused, and ended blindly. The small colon was collapsed and completely closed at its cranial end. The right and left dorsal and ventral colons were fused into one blind-ended tube. Histologically, eosinophilic intranuclear inclusion bodies demonstrative of Equine Rhinopneumonitis were present in the thymus.
Injectable anesthetics and anesthetic adjuncts. The purpose of this article is to review the use of selected anesthetics and anesthetic adjuncts in horses. Emphasis is placed on the pharmacologic bases of their use.
Hormone therapy for control of reproduction in mares and stallions. Because the reproductive performance of mares is lower than that of any other domesticated species, hormone therapy is important in ensuring fertility and proper management of pregnancy. Current techniques of hormone therapy are discussed.
A clinical trial of three anaesthetic regimens for the castration of ponies. After premedication with intravenous xylazine 30 ponies were anaesthetised for castration under field conditions with intravenous ketamine, thiopentone or methohexitone. The duration of anaesthesia was adequate for surgery and the times taken to stand were similar in each group. The recovery of the ponies after ketamine was quieter than after either of the barbiturates and this may be an advantage when skilled assistance is lacking. However, all the anaesthetics appeared to be suitable for performing minor surgery in the field.
Chronic nongranulomatous enteritis in seven horses. Chronic nongranulomatous intestinal inflammation was found during laparotomy in 7 horses. The clinical signs consisted of recurrent abdominal pain in all horses. Anti-inflammatory agents (corticosteroidal and nonsteroidal agents) appeared to be effective for controlling the signs. Surgical removal of the involved intestine also was effective. Nonocclusive or temporary mesenteric ischemia was proposed as a cause of the intestinal lesions.
Surgical reconstruction of chronic coronary band avulsions in three horses. Three adult horses were admitted with chronic coronary band avulsions of 2-, 3-, and 46-month durations, respectively. The hoof had a typical appearance in all 3 horses, with a spur of coronary band and associated horn growing at right angles to the hoof wall. Each horse was anesthetized, and the coronary band was reconstructed. Follow-up evaluation of the 3 horses (12, 15, and 23 months after surgery, respectively), revealed healing of all 3 avulsed coronary bands. Mild roughening of the hoof wall distal to the previous avulsion site was observed.
Acquired immunodeficiency in a seven-year-old horse. A 7-year-old horse with no previous history of illness was determined to have a systemic infection of Rhodococcus equi. Rhodococcus equi was isolated from blood, tracheal fluid, and feces. Lymphopenia, failure to respond to concanavalin A and phytohemagglutinin lymphocyte stimulation testing, decreased concentrations of immunoglobulin (Ig)M, IgA, and IgG, low R equi antibody titer, histologic depletion of lymphoid tissue, and a failure to respond to antigenic stimulation led to the conclusion that both humoral and cell-mediated immunity were compromised. No cause for the acquired immunodeficie...
Diagnostic value of tissue biopsy in gastrointestinal and liver disease. Methods are described for the endoscopic examination and biopsy of the gastrointestinal tract and liver of the dog, cat, ox and horse. The results of the examination of 41 biopsy samples are shown, followed by a discussion of the value of biopsy in the diagnosis of diseases of the digestive tract.
Condylar fracture of the cannon bone with axial sesamoid fracture in three horses. The case histories of three young thoroughbred racehorses with displaced lateral condylar fractures combined with an axial fracture of the lateral sesamoid bone are described. In two cases the condylar fracture was repaired surgically but both horses developed severe degenerative joint disease and remained lame. The third horse was destroyed humanely. It is important that axial fractures of the sesamoid bone are recognised so that a poorer prognosis can be given for treatment of condylar fractures in racing thoroughbreds.
Juvenile granulosa cell tumour in an equine weanling. A juvenile granulosa cell tumour is described in a 3-month-old Arabian filly. The 32 X 27 X 27 cm tumour had replaced the right ovary. The neoplasm was composed of multiple nodules of neoplastic granulosa cells which formed microfollicles, macrofillicles and cysts, as well as solid nests and trabeculae. The supporting stroma contained theca cells. Mixing of the neoplastic granulosa cells and theca cells in disorderly fashion was noted. The diagnosis was based on age of occurrence and histological appearance.
Comparison of various treatments for experimentally induced equine infectious arthritis. To evaluate the effects of 5 treatments on clinical responses, synovial fluid analysis, radiographic changes, bacteriologic culture results of the synovial fluid and synovial membrane, microscopic characteristics of the synovial membrane, and articular cartilage histochemistry, Staphylococcus aureus organisms (1.6 X 10(6) colony-forming units) were inoculated into the tarsocrural joints of 12 horses (n = 24 joints; 2 joints/horse). Each horse was given phenylbutazone (2 g) orally, every 24 hours, beginning 24 hours after inoculation. Two horses (ie, 4 joints) were not given other treatment (co...
Equestrian injuries: a comparison of professional and amateur injuries in Berkshire. A retrospective study of horse riding injuries in Berkshire was undertaken over a one year period from November 1983. The information was obtained from the Ambulance Service, the Jockey Club and the St. John Ambulance Brigade. There was a total of 103 injured persons with no deaths. Information from the Jockey Club was compared with the other two groups, the former sustaining more limb injuries and the latter more head injuries. A questionnaire was sent to all 42 ambulance patients. Thirty-eight had radiographs taken, 16 of which showed a fracture. Forty-one were wearing some form of hard hat,...
Social relationships in a herd of 11 geldings and two female ponies. The social behaviour of a small herd of 10 Exmoor geldings, two Exmoor mares and one Highland pony gelding was studied in order to see whether any specific associations existed between ponies and, if so, whether these applied to all or only some of the ponies' main activities of grazing, eating hay and sleeping. Such relationships were found but only in a small number of cases did they apply to all activities. The results are discussed in relation to the individual histories of these ponies and in relation to the welfare of horses.
