Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Nakajima H, Yoshino T, Ushimi C.Equine infectious anemia virus was purified from infected horse serum samples. Electron microscope observation on negatively stained preparations of purified virus showed roughly spherical particles sized between 100 and 200 nm in diameter. In disrupted particles, an envelope was visible but no internal structure could be resolved. Since the purified virus fraction had a strong antigenic activity to antiserum in immunodiffusion reaction, these particles are thought to be the causative virus of equine infectious anemia.
Swierstra EE, Gebauer MR, Pickett BW.The cycle of the seminiferous epithelium of the stallion was
divided into eight stages, using as criteria the presence of meiotic divi-
sions, shape of the spermatid nuclei and location of spermatids with
elongated nuclei in the tubule. The mean frequencies ofstages 1 to 8 were
16\m=.\9, 14\m=.\9, 3\m=.\2, 15\m=.\8, 7\m=.\4, 13\m=.\5, 12\m=.\6 and 15\m=.\7%, respectively. The
duration of one cycle of the seminiferous epithelium was 12\m=.\2 days
(S.E.\m=+-\0\m=.\1) as determined by injecting a single dose of 700 \g=m\Ciof
[3H]thymidine into each spermatic artery of six stallions and rem...
Galloway SS, Earley ET.Oral extraction has become the most popular extraction technique owing to its high rate of success with minimal major complication. Repulsion continues to produce unacceptably high iatrogenic complication rates. To avoid tooth repulsion, veterinary dentists have introduced procedures to facilitate difficult intraoral extractions and surgical extraction techniques. Minimizing complications is best achieved preoperatively. A comprehensive preoperative evaluation and treatment plan allows the dentist to predict intraoperative complication and prepare for procedures to produce the best outcome. Wi...
Freeman DE, Donawick WJ, Klein LV.The effect of a single ligature on back pressure in the internal carotid artery was studied in nine horses. In six anesthetized horses, one internal carotid artery was catheterized 2 cm from its origin and blood pressure was recorded continuously. Then the artery was ligated, pressure was recorded again, and the horses were euthanatized. In another three anesthetized horses, indwelling catheters were placed in both internal carotid arteries and a loose ligature was placed proximal to one catheter. After horses recovered from anesthesia, the ligature was tied and blood pressure was recorded in ...
Gudev Kh, Kovachev G.Alantoamnion vascularization was studied on clarified preparations from three mares in advanced pregnancy. Two large blood vessels (artery and vein) beginning from the umbilical vessels were found in the alantoamnion wall. Numerous anastomoses were observed at the passage between the arterial and the vein section. The large arteries had a thick, jely-like vascular wall and snake-like folded lumen. In separate sections of the alantoamnion wall a well developed capillary net was observed consisting of individual particles, polygonal in shape. Vast avascular zones surrounded by numerous vascular ...
McLeland S.Uncommon diseases of the equine urinary system span a variety of etiologies and frequently have nonspecific clinical presentations. Because of the infrequency of equine urinary disease and inconsistencies in clinical symptoms, diagnosis and subsequent treatment of urinary disease in this species may be challenging. This article reviews various diseases of the equine urinary system, morphologies, and potential discriminating clinical and clinicopathologic presentations to aid the clinician in determining a definitive diagnosis in practice.
French DD, Klei TR, Taylor HW, Chapman MR.Twenty-one mixed-breed pony foals, reared and maintained under parasite-free conditions, were used to test the efficacy of ivermectin in oral drench and paste formulations (200 micrograms/kg) against 11-day-old migrating larvae of Parascaris equorum. Three replicates of 4 foals and 3 replicates of 3 foals were formed on the basis of age. Foals in replicates of 4 were randomly allocated to be indicators, or to receive vehicle (control) or ivermectin paste or ivermectin liquid. Foals in replicates of 3 were randomly allocated to receive vehicle or ivermectin paste or ivermectin liquid. The recov...
Graves MT, Anderson DE, DeNovo RC.Large animal teaching hospitals often struggle to maintain consistent teaching caseloads, which are affected by seasonal variations, economic pressures, increased abilities of local large animal practices to hospitalize large animals, and client intolerance for the operational needs of an academic mission. Non-academic large animal practices enjoy a more consistent caseload but suffer from a lack of emergency relief and a limited ability to share emergency duties, which may have adverse effects on work-life balance. An academic, on-farm, large animal emergency relief service can combine multip...
Beroza GA, Perry RW, Cotter DM.Permanent implantation of nonabsorbable materials is appropriate in many surgical circumstances but is not commonly used to close equine celiotomies. This paper describes a simple method of continuous nonabsorbable implantation of polyamide suture used successfully to close 48 equine celiotomies. Forty-eight clean or clean-contaminated celiotomies were successfully performed over 5 years using this technique. The postsurgical survival observation period ranged from 1-6 years (median 3.5 years). There were 45 long-term survivors (93.75%). Only 2 minor implant complications (4.4%) were observed ...
Hinrichs K.A research study is a product of not only a question and its pursuit but also the people, places, and facilities available at the time. My work in equine assisted reproduction has progressed from embryo transfer to oocyte maturation, oocyte transfer, intracytoplasmic sperm injection, embryo biopsy, embryo vitrification, and cloning, as a result of collaborations with an array of remarkable people. This is a summary of some of the stories behind the studies.
Bo Minelli L, Acone F, Zedda M, Sanna L.The retractor penis muscle originates from the vertebrae in pigs, horses, cattle and goats; it arises from the rectum in sheep. In all the species considered, sensitive innervation was found. This was represented by encapsulated receptors. Nervous vegetative supply, made up of isolated or assembled ganglion cells, was also present. Among the numerous sensory nerve endings found in pigs, goats and sheep were Pacinian, Pacinian-like, Golgi-Mazzoni corpuscles and Krause's end bulbs (genital corpuscles). Few Pacinian and Pacinian-like corpuscles were found in cattle and horses. A hypothesis on the...
