Topic:Equine Health
Equine health encompasses the study and management of diseases, disorders, and overall well-being of horses. It involves understanding various physiological systems, preventive care, and treatment strategies to maintain optimal health in equine populations. Common areas of focus include nutrition, infectious diseases, orthopedic conditions, and reproductive health. Research in equine health aims to advance knowledge on diagnostic methods, therapeutic interventions, and management practices that improve horse welfare and performance. This page collects peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine health, offering insights into current findings and advancements in the field.
Treatment of fear-induced aggression in a horse. Desensitization (gradually exposing an animal to a fear-inducing stimulus without evoking the fear response) and counter-conditioning (rewarding the animal for behavior incompatible with the fear response) are highly successful ways of eliminating or reducing fear responses and corresponding aggression.
A gas chromatographic screening procedure for the detection of non-steroidal anti-inflammatory drugs in horse urine. A gas chromatographic screening procedure for the non-steroidal anti-inflammatory group of drugs is described. The method invovles on-column methylation of the carboxylic acid group using trimethylanilinium hydroxide as the methylating reagent. Fifteen such drugs were studied. Eight of these were detected in urine collected from horses that had received these compounds orally and for these drugs, rates of urinary excretion are recorded. Seven other members of this group of drugs were shown to be detectable by this procedure but in these cases the drug was added to urine and not administered to...
Physiologic effects of succinylcholine chloride in mechanically ventilated horses anesthetized with halothane in oxygen. Succinylcholine chloride, administered to horses anesthetized with halothane in oxygen and mechanically ventilated, caused slight but significant (P less than 0.01) increases in heart rate. Significant alteration in mean arterial blood pressure did not occur, and there were clinically insignificant increases in serum K+ and C1- concentration. Cardiac dysrhythmia and myoglobinuria did not occur. Thus, effects of halothane anesthesia and mechanical ventilation prevented cardiac dysrhythmia and hypertension and greatly reduced the tachycardia generally associated with siccinylcholine administrati...
Assessment of myocardial function in the horse. 1. Theoretical and technical considerations. The paper discusses the various parameters which are currently used in attempts to assess the contractile efficiency of the myocardium in various species. These procedures depend upon accurate recording of intracavity pressure. The response of a catheter-mounted microtransducer compared with a fluid-filled catheter manometer system is illustrated to show the advantage of the former in providing a true representation of pressure changes.
An outbreak of foal perinatal mortality due to equid herpesvirus type 1: pathological observations. Twenty-nine cases of EHV1 infection occurred on a property, mainly in full term foals. Some foals were stillborn, some were born alive but weak and soon died and others were healthy at birth, became ill and died within 3 days of birth. Apart from voluminous, oedematous and atelectic lungs there were no gross lesions. Microscopically the lungs showed oedema, pneumonitis and bronchiolitis with intranuclear inclusions and, in many of the foals that survived over 6 hours, there was also hyaline membrane formation. Microscopic lesions were also seen in the liver, adrenal, thymus and spleen of some ...
Hemodynamic and respiratory effects of xylazine-morphine sulfate in horses. The cardiopulmonary effects of two xylazine-morphine sulfate drug combinations (mixtures) given IV were evaluated in horses. In horses given xylazine (0.66 mg/kg of body weight) and morphine sulfate (0.12 mg/kv) IV (experiment 1), there were significant (P less than 0.05) decreases in heart rate, cardiac output, and respiratory rate. Central venous pressure was significantly (P less than 0.05) increased. Arterial and pulmonary arterial blood pressures increased significantly (P less than 0.05) but transiently. Arterial blood gas tensions (PaCO2 and PaO2) and pH remained unchanged. In the horse...
Case report: equine colic associated with sand impaction of the large colon. In most cases the outcome of impaction of the colon is favourable and with mild purging and lubrication, the mass can be broken down and the horse returned to normal health. It is important to reevaluate impaction cases which neither deteriorate or improve in a 24 hour period and to perform a paracentesis to evaluate the etiology and prognosis. A decision of euthanasia or surgical correction should be made as early as possible. Though initially stable, vital signs will deteriorate rapidly without warning. A critical evaluation of the client's farm management can prevent many impaction colics a...
A re-evaluation of the D (+) xylose absorption test in the horse. The absorption of d-xylose forms the basis of a useful screening test in the investigation of small intestinal disorders in the horse. A comparison has been made of different assay methods and there was no significant difference between the results obtained with the parabromoaniline (PBA) method or the ferric chloride-orcinol (FCO) method. The orthotoluidine method was unsatisfactory. The anticoagulant agent did not affect the test. A dose of 0.5 g commercial grade xylose/kg body weight as a 10 per cent solution given by stomach tube, produced a peak plasma xylose level after 90 min and should...
Evaluation of equine radial and median nerve conduction velocities. Eleven ponies and 13 horses were used to develop a technique for determining conduction velocity for the radial and median nerves and establishing normal limits for these values. One pony was euthanatized to determine the course of the radial and the median nerves. From this dissection, both proximal and distal stimulation sites for the radial and the median nerves were selected, as well as areas for recording muscle evoked responses from the abductor digiti I longus (extensor carpi obliquus) and the radial head of the deep digital flexor muscles. The other ten ponies and the horses were used ...
Chronic phenylmercuric acetate toxicity in a horse. Phenylmercuric acetate (PMA) was administered orally to a horse over a period of 27 weeks (190 days) at a dose rate of 0.4 mg Hg/kg per day. The effects produced were consistent with those of chronic inorganic mercury intoxication. The clinical features included masseter muscle atrophy, difficulty in prehension and mastication, malodorous breath, reduced appetite and weight loss, and reflected significant pathological changes involving the buccal, mandibular and dental tissues. Renal dysfunction was evident terminally and there was degeration and necrosis of the proximal tubular epithelium. Ne...
A probable congenital diaphragmatic defect in an adult pony. The presenting signs exhibited by a pony with a large diaphragmatic defect of probable developmental origin are described. The results of clinical examination, laparotomy and post mortem examination are presented.
Treatment of sprained tendons in horses with carbon fibre implants. A technique for implanting carbon fibre into sprained flexor tendons in horses is described. Insertion of the fibres through paravertebral needles which passed through the affected region of the tendon was considered to be preferable to direct implantation into the surgically opened tendon. The results of the eight cases treated to date are dealt with briefly, together with a discussion as to how this form of treatment could be further evaluated.
Horse markings: their importance to the integrity of racing and breeding. The difficulties that arise in filling out marking certificates for thoroughbreds are described. The description given on the certificate has to be both written and graphic. A general guide to whorl location is given.
