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.
Stromberg BR, Norberg AW.Forty-six horses were submitted to a thermographic screening test. Forty showed a reasonably uniform IR-emission pattern of the coronary corium of the forelegs. The 133Xe-disappearance rate was studied in six of these horses, and the wash-out curves were found to be almost similar between the two extremities of each horse, except for slight differences between individual horses. Six horses showed a different IR pattern. Three had both coronary bands, and three had one coronary band, showing lower temperature. All cases with less warm coronary bands showed a low 133Xe-disappearance rate at rest...
Bjorck G, Nilsson G.Sixteen cases of chronic hoof changes seen in Standardbred trotters are described. The chief defect is decomposition of the horn. The disease process usually commences on the weight-bearing surface and spreads to underrun both the sole and wall. Histopathological studies revealed marked swelling and vacuolation of the cells of the stratum corneum, increased proliferation in the stratum germinativum, and monocytic infiltration in the corium. Treatment comprised complete removal of underrun horn and exposure of the affected area. In severe cases, a course of penicillin is administered. The lengt...
Lores M, Yarbrough T.A 9-year-old pony gelding was evaluated because it was suspected that a persistent oronasal fistula had developed after a fractured right maxillary second premolar tooth had been extracted via repulsion 6 months earlier. Results: Unilateral mucopurulent nasal discharge and malodorous breath were noted on clinical examination. Examination of the oral cavity revealed a 1 × 0.5-cm defect at the oral aspect of the right maxillary second premolar alveolus, from which feed material was extracted. Endoscopic examination revealed feed material in the rostral aspect of the right nasal cavity, confirmi...
Lloyd JW, Kaneene JB.A study was developed to describe direct expenses, labor use, and performance days lost associated with health management in the Michigan equine industry. A prospective design with stratified, random sampling, was employed involving 77 operations from February 1992 through January 1993, and 61 different operations from May 1993 through April 1994. Data on the cost of health management were collected during monthly visits, and included monetary expenditures, death losses, days lost, and labor use. Median health care costs (when they were incurred) were $4.84 per horse per month for monetary exp...
Vice JD, Shoemaker RS, Cho DY.A 2-year old Thoroughbred filly was examined for a 1-month history of persistent nasal discharge. Contrast radiography revealed a circumscribed mass within the right maxillary sinus which extended to the frontal sinus and ethmoid labyrinth. A discrete attachment of the mass to the ethmoid labyrinth was identified at surgery. Surgical removal of the mass eliminated the nasal discharge. On gross examination, the external structure of the mass was similar to a turbinate with a thin bony wall covered by a smooth mucosal membrane. The internal structure of the lesion had a lining membrane with mult...
Changoor A, Hurtig MB, John Runciman R.Multiple osteochondral grafts can be used to resurface large joint defects in both humans and horses. In humans, immediate postoperative weight bearing can be prevented, however in the equine, it is unavoidable. Early weight bearing can create detrimental graft micromotion. The aim of this study was to investigate the role of a bioresorbable cement in improving the initial stability of multiple osteochondral graft repairs of large subchondral cystic lesions in the horse. Configurations employed for filling a 20mm diameter cylindrical defect included: (A) twelve 4.5mm diameter grafts with cemen...

Sonnichsen HV.Dexon is a new, synthetic, absorbable suture material. Its applicability for suturing distally in the extremities of horses was tested in 65 cases. The indications included burried sutures as well as skin closure. It was concluded that the material can be used with advantage in cases traditionally sutured with catgut, vetafil or mersilene. It is technically a pleasant material and has further the advantage that it shall not be removed.
de Vries PJ, van der Holst W.The reliability of determination of the plasma progesterone level within approximately eighteen days after ovulation in the pregnancy diagnosis of mares is examined in the present study. Studies were done in seventy-five mares, a number of which were served or inseminated during several cycles so that a total number of eighty-seven blood samples were obtained. On the analogy of other authors, the progesterone level above which mares were believed to be pregnant and below which they were assumed to be non-pregnant, was set at 2 ng/ml. The twenty-five mares in which the level was below 2 ng/ml. ...
Vidović A, Jansen D.The first part of this case report describes the surgical treatment of a unilateral mandibular fracture in the standing horse by using a fixateur type I. By the time of implant removal, the fracture had completely healed. However, during implant removal, an implant failure of 2 of the 4 implants occurred with fragments remaining in the bone. The second part of the report focuses on the development of a special surgical instrument that was designed for removal of the implant fragments. Furthermore, the surgical method allowing the entire extirpation of the fragments within a second surgery is d...
Hall LW, Young SS.Total respiratory resistance was measured rapidly and non-invasively in 6 conscious ponies before and after they inhaled approximately 25% of the minimal anaesthetic concentration (0.25 MAC) of either enflurane, halothane, or isoflurane, over a 10 min period. The forced random noise (FRN) method was used to measure the impedance over the frequency range of 5 to 40 Hz and its real part, the resistance, was extracted from these impedance measurements. At the concentrations used, halothane appeared to have no effect on the total respiratory resistance; enflurane and isoflurane seemed to increase ...
Ho EN, Kwok WH, Leung DK, Wan TS, Wong AS.Turinabol (4-chloro-17alpha-methyl-17beta-hydroxy-1,4-androstadien-3-one) is a synthetic oral anabolic androgenic steroid. As in the case of other anabolic steroids, it is a prohibited substance in equine sports. The metabolism of turinabol in human has been reported previously; however, little is known about its metabolic fate in horses. This paper describes the studies of both the in vitro and in vivo metabolism of turinabol in racehorses with an objective to identify the most appropriate target metabolites for detecting turinabol administration. For the in vitro studies, turinabol was incub...
Yang JM, Woods WE, Weckman TJ, Wood TW, Chang SL, Blake JW, Tobin T.1. Drug administration studies using diisopropylamine dichloroacetate (DADA) and diisopropylamine (DIPA) were conducted in Thoroughbred and Standardbred horses to assess physiological effects and develop detection methods. 2. Four horses received 0.08 mg DADA/kg body wt and showed no changes in heart and respiratory rates or body temperature as measured over a 1-hr period after administration. A transient diuretic effect was found to occur in 2 mares dosed with 0.80 mg DADA/kg body wt. 3. A qualitative detection method using thin-layer chromatography was developed to detect DIPA, the major met...
