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.
Fertility, ovulation and maturation of eggs in mares injected with HCG. Pony mares were observed from January to August for incidence of oestrus, duration of oestrus, length of the oestrous cycle and for ovulation and fertility after injection of HCG. From January to 15 May most mares showed oestrus but the duration of oestrus was quite variable and few mares ovulated in response to HCG. From 15 May to 17 August oestrous cycles were more regular and ovulation was induced within 40-50 h by an intramuscular injection of 1500-5000 i.u. HCG. Pregnancy was established by one mating at a fixed time after HCG in 20 of 69 mares. Degenerate eggs were recovered from the ovi...
[Veterinary and clinical experience of the use of a beta2-receptor-stimulating sympathicomimetic agent (NAB 365) in horses with respiratory discase (author’s transl)]. The manufacturers state that NAB 365 is a beta2-receptor-stimulating sympathicomimetic agent. According to the medical literature it combines a bronchial antispasmodic effect with certain bronchia secretolytic properties and has few untoward side-effects on, for instance, the heart and intestine. The effectiveness of administration of NAB 365 in horses with chronic or acute respiratory disease was tested in the Department of Veterinary Internal medicine in Utrecht. NAB 365 administered at a dosage of 0.8 gamma/kg, of body weight was found to have a marked bronchodilative effect in horses. Ther...
Paroxysmal atrial fibrillation in a racehorse. A 4-year-old thoroughbred stallion with a history of loss of racing form was studied over a period of approximately 7 months. At the initial examination he showed positive T waves in 1 chest lead and wandering of the pacemaker. This was followed by an episode of paroxysmal atrial fibrillation which disappeared spontaneously and was replaced by significant T wave changes in all the chest leads. During a period when these changes persisted, there was progressive lengthening of the P wave and the P-R interval. Because the last ECG showed evidence of intra-atrial block, first degree A-V block and ...
An epidemic of venereal infection in thoroughbreds. The clinical pattern, bacteriological investigation and subsequent treatment of a serious outbreak of venereal disease in stud farms on both sides of the Irish Sea is described. The consistency with which Bacillus proteus was isolated from infected mares and stallions was remarkable. Prompt treatment with ampicillin, to which the organism was sensitive in vitro, eradicated the disease. No local treatment was applied.
Arrhenoblastoma in a mare. An ovarian neoplasm measuring 10 by 8 by 6 cm was surgically removed from a 14-year-old Appaloosa mare. For 2 years prior to surgery, the mare had manifested marked behavioral changes, becoming aggressive toward other broodmares. Histologically, the tumor was found to be an arrhenoblastoma. Preoperative endocrinologic findings (high serum testosterone and low serum estradiol concentrations) supported the diagnosis.
[Phantoms for the collection of genital secretions in stallions]. Practical experiences of the phantom method for collection of genital secretions from stallions are reported. Taking a phantom used in the Richard-Götze-Haus Tierärztliche Hochschule Hannover as a prototype two further models slightly modified have been constructed, baring a flat hollow in the right side of the caudal phantom body for manual inserting of the Artificial Vagina. These three models fulfill four important conditions for routine use: (1) sufficient sexual attractivity for the stallions; 80-85% successful collections of presecretions out of a total of 1050 using the dummy and 70% ...
[The arterial vessels and their intraosseous course in the leg bones of foals. II. Humerus]. The arterial blood vessels in 24 humeri of equine fetusses and foals are described. The relation between the age and the distribution of these arteries are explained and completely discussed.
The value of arterial blood pressure measurement in assessing the prognosis in equine colic. Indirect arterial blood pressure was determined on 33 horses prior to surgical intervention for the diagnosis and/or correction of acute abdominal disorders and a relationship between low systolic blood pressure and non-survival was established. It is suggested that blood pressure determination should be used to augment other methods of clinical and laboratory examination in cases of equine colic.
Observations on the life cycle and prevalence of Eimeria leuckarti in horses in Montana. Of 22 foals from 4 localities in southwestern Montana, 59% were found to be infected with Eimeria leuckarti. Oocysts collected from feces of 4 positive horses were sporulated and subsequently administered to a 5- to 6-month-old foal. The prepatent period was 31 days and the patent period was between 5 and 10 days.
Intramural esophageal cyst in a horse. A yearling Quarter Horse colt was examined because of intermittent esophageal obstruction. A soft tissue mass was palpated in the cervical portion of the esophagus. Plain and contrast radiography and esophagoscopy were utilized to confirm the location of the lesion in the esophageal wall. Surgical exploration and removal of the mass was performed through a ventral midline cervical incision. Histologically, the mass was a keratinizing squamous epithelial inclusion cyst.
Cardiological problems in equine medicine. This paper outlines the major problems in evaluating and assessing prognosis in horses with minor cardiac abnormalities. It emphasises that progress will only be made if adequate data on the "natural history" of equine cardiac disease can be collected. This will necessitate a long-term study of suitable cases and will require the collaboration of specialist institutions and general practitioners if it is to be successful.
Pacing techniques in assessing cardiac function in the horse. The problem of transitory cardiac arrhythmias in equidae is discussed particularly with regard to the referral of suspect cases to specialist institutions for second opinion. Recently developed electro-stimulation techniques designed to uncover problem arrythmias, are briefly described and their potential in the analysis of cardiac electrical function under varying conditions is reviewed. The author cautions on the too rapid evaluation of the techniques for this purpose while remaining optimistic of the potential of electro-stimulation in the objective analysis of cardiac electric parameters.
A critical review of current methods for induction of parturition in the mare. The efficacy and safety of oxytocin, dexamethasone and prostaglandin, used alone or in combination as inducing agents, are discussed. It is contended that insufficient evidence exists to support the routine application of any of these methods in practice. Oxytocin has been the most widely used and it is claimed by some to be free from side effects. However, the synthetic prostaglandin analogue, fluprostenol, seems to pose the least risk to the foetus and dexamethasone appears to be either ineffective, or too dangerous to use at all. The main indications for induced foaling are managerial conve...
The clinician’s approach to equine cardiology. The author considers some of the difficulties the clinician may be faced with when giving an opinion on a horse with a cardiac abnormality. The 3 types of cardiological cases presented to the practitioner are described. The first 2 categories both exhibit a reduction in performance either with loss of bodily conduction or without it. The third group, which is the most troublesome for the clinician, involves the horse which shows a cardiological abnormality but is otherwise apparently normal.
Syringomyelia in a thoroughbred foal. The report describes a case of myelodysplasia involing spinal cord segments C7 to T8 of a 5 month old part-Thoroughbred foal. There was a single extensive syringomyelic and hydromyelic cavity which extended from the seventh cervical segment (C7), to the seventh thoracic segment (T7), abnormal size and shape of central canal, and disorderly differentiation of the grey and white matter. The cause of the defect is unknown.
Coxofemoral luxation complicated by upward fixation of the patella in the pony. Two cases of coxofemoral luxation complicated by upward fixation of the patella are described in the pony. Clinical signs included outward rotation of the stifle and foot and inward rotation of the hock with the stifle and hock joints fixed in extension. One case was treated by performing a medial patellar desmotomy with a resultant significant improvement in locomotion. Other cases of hip luxation reported in the literature, some complicated by upward patellar fixation, are reviewed. Hip luxation is principally seen in ponies and it is suggested that upward fixation of the patella occurring i...
Chronic tenosynovitis of the extensor tendons and tendon sheaths of the carpal region in the horse. Seven cases of chronic tenosynovitis affecting the extensor carpi radialis or lateral digital extensor tendon and their sheaths are described. All cases were chronic and in 4 of the cases previous treatment by drainage and local corticosteroid injection had been ineffective. Surgical exploration of 6 cases demonstrated a distinct lesion and specific surgical treatment was carried out.
Radiological protection in equine radiography and radiotherapy. The principles of radiological protection are summarised and consideration is then given to problems, which may confront the equine practitioner, in the fulfillment of these principles during diagnostic radiography of the limbs, head, and spine of the horse. The place of anaesthesia in such procedures is discussed and the special problems associated with therapeutic radiography of the horse are considered.
Familial methaemoglobinaemia and haemolytic anaemia in the horse associated with decreased erythrocytic glutathione reductase and glutathione. A trotter mare with a history of poor performance was found to have methaemoglobinaemia and haemolytic anaemia associated with decreased erythrocyte glutathione reductase and glutathione levels. The mare's dam, which also had a history of poor performance, was subsequently found to be similarly affected.
