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.
Morris CD, Whitney E, Bast TF, Deibel R.During August 1971 three horses died and one human infant became ill during an outbreak of Eastern equine encephalomyelitis in Upstate New York. Fifteen of 93 wild avian sera collected in the area reacted in hemagglutination-inhibition (HI) tests with Eastern equine encephalomyelitis (EEE). EEE virus was isolated from four avian specimens (White-throated Sparrow, Towhee, Baltimore Oriole, Cedar Waxwing) and 5 of 159 arthropod pools (3 from Culiseta morsitans and 1 each from Culex territans and Culex restuans). Sera from 54 humans and 89 healthy equines were HI-negative for EEE. It is believed ...
Matczuk AK, Zhang M, Veit M, Ugorski M.Equine arteritis virus (EAV), an enveloped positive-strand RNA virus, is an important pathogen of horses and the prototype member of the Arteiviridae family. Unlike many other enveloped viruses, which possess homotrimeric spikes, the spike responsible for cellular tropism in Arteriviruses is a heterotrimer composed of 3 glycoproteins: GP2, GP3, and GP4. Together with the hydrophobic protein E they are the minor components of virus particles. We describe the expression of all 3 minor glycoproteins, each equipped with a different tag, from a multi-cassette system in mammalian BHK-21 cells. Copre...
Katić I, Kristiansen J.For almost 20 years the authors have been selecting and editing the material referring to the means of transport which Danish veterinarians used in the 18th, 19th and 20th century. The source material contains memoirs, advertisements from veterinary medical journals, obituaries and other sources, based on which a 210-page book in the Danish language has been published. The article presents an abridged version of this book. In Denmark, the first veterinarians rendered their services at the time when this profession had not yet established itself. They were relatively poor and very often they ha...
al-Bagdadi F, Hoyt P, Karns P, Martin G, Memon M, McClure R, McCoy D, Shoemaker S.Eleven unilateral cryptorchid stallions, two to three years old, were castrated at Louisiana State University Veterinary Teaching Hospital. Five of these cryptorchid cases were abdominal and the rest were inguinal. This study was initiated to document the differences between the abdominal and inguinal equine cryptorchid testes. Specimens were obtained from the abepididymal side of each cryptorchid testes and processed for light and electron microscopic study. The cryptorchid testes were smaller than the scrotal testes, with the abdominal testes being one-fourth the size of the scrotal testes. ...
Stewart JH, Rose RJ, Barko AM.The effect of oxygen administration on blood gas values was examined in six newborn foals from birth to seven days old. Three variables were studied: the effect of increasing age on the ability to elevate arterial oxygen tension (Pao2), the effect of duration of oxygen delivery on Pao2 and the effect of method of administration. The results demonstrated a significant effect of age on the ability to increase Pao2 values, with the highest Pao2 values being found at seven days old. The duration of oxygen administration caused little change in Pao2 values; peak values were reached after 2 mins of ...
Landolt G, Feige K, Schöberl M.The present study describes the poisoning due to Robinia pseudoacacia in two horses. One of the horses showed mainly intestinal symptoms such as decreased intestinal motility and obstipation of the pelvic flexure. In the second animal central nervous symptoms were predominant. It showed intermittent phases of somnolence alternating with phases of excitation and head pressing. In addition mydriasis and a lacking menace response could be observed. Sensation to the head and the spinal reflexes were reduced. Symptomatic treatment was initiated in both animals and recovery occurred within 2 days.
Levine DG, Ross BM, Ross MW, Richardson DW, Martin BB.Decreased radiopharmaceutical uptake, photopenia, in delayed phase scintigraphic images is recognized in people but has only been reported rarely in horses. We describe three horses with septic osteitis, bone sequestrum formation, or distal limb thrombosis that had photopenia of the affected extremity. Photopenia may indicate the presence of ischemia and can be used to facilitate clinical decision making and prognosis assessment
Magee C, Bruemmer JE, Nett TM, Squires EL, Clay CM.Kisspeptides (KiSS) are a recently discovered family of neuropeptides with a central role in regulating the onset of reproductive function in all animals studied to date. We have established biological and physiological evidence for KiSS signaling in the mare. The objective of the current study was to evaluate the physiological and behavioral responses of mares repeatedly given the equine-specific kisspeptpin decapeptide (eKp-10, YRWNSFGLRY-NH(2)) in an effort to shorten the interovulatory period. Administration of eKp-10 (0.5 mg iv every 4 h) to mares beginning on Day 16 postovulation (Group ...
Reid N.A round mass 4 cm in diameter was present on the proximal rostro-lateral border of the right pinna of a 10-year-old, gelded, Paint horse. A preliminary histopathological diagnosis of a potential squamous cell carcinoma and peripheral nerve sheath tumor was made, and the lesion was resected at the base of the lateral edge of the ear. Une masse ronde de 4 cm de diamètre était présente sur le bord rostrolatéral proximal du pavillon de l’oreille droite d’un Paint horse castré âgé de 10 ans. Un diagnostic histopathologique préliminaire d’un carcinome squameux et d’une tumeur de la ...
Kobluk CN, Gross GM.This article deals with the presenting histories, clinical examinations, and therapies of the causes of poor performance and exercise intolerance in the western performance horse and the sprint racehorse. The veterinarian's ability to diagnose and treat various pathophysiologic conditions that affect these horses is crucial to the major goals of a return to optimal performance and a long athletic career. Although these horses are a significant portion of most veterinary practices, there exists a minimal amount of information on their clinical evaluation and treatment. This article intends to f...
Hinrichs K, Schmidt AL, Memon MA, Selgrath JP, Ebert KM.Embryos were recovered from the uteri of mares 5 d after ovulation. Six embryos, all morulae, were placed singly in 200-ul droplets of Ham's F-12 with 10% fetal calf serum and cultured at 37 degrees C in a 5% CO(2) atmosphere. The embryos expanded to form blastocysts by the third day of culture. The blastocysts hatched from their zona pellucida, rather than the zona thinning and flaking off, as occurs in vivo. Hatching from the zona pellucida began on the third day of culture and was complete in five of six embryos by the sixth day. The embryonic capsule, normally present in equine embryos aft...
Viljanto M, Cutler C, Taylor P, Habershon-Butcher J, Gray B.MK-0677 (ibutamoren) is an orally active non-peptide growth hormone secretagogue that binds to the ghrelin receptor stimulating the secretion of endogenous growth hormone. It is one of the most prevalent performance-enhancing compounds currently available online and is potentially subject to abuse both in human and equine sports. The aim of the current study was to investigate whether it could be detected in equine hair following oral administration of MK-0677 mesylate to a Thoroughbred racehorse. MK-0677 and its O-dealkylated metabolite were extracted using an existing method for prohibited s...
Barban PS, Gol'din RB, Misenzhnikov AV, Prusakova ZM, Pantiukhina AN.The authors present the results of immunization of horses-producers with a commercial antigen and the yolk culture of the living R. sibericus (strain K1) for the purpose of obtaining specific immune sera for many purposes. It was shown that the original combined scheme of immunization and reimmunization of horses, successfully approved in the preparation of immune sera to Rickettsia prowazeki also proved to be highly effective for obtaining the antisera to R. sibericus. Sera obtained after the primary immunization of horses could be successfully used as diagnostic sera, but they were of no use...
