Topic:Veterinary Care
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.
Acquired torticollis in eleven horses. Case records of 11 horses with acquired torticollis during a 15-year period were reviewed. The cause was established in seven of eight cases and included cervical intervertebral disk protrusion, skull fracture, neurogenic atrophy, and dystrophic myodegeneration. The latter condition was considered to be the most likely cause in the three horses that recovered.
Effect of pneumatic tourniquet application to the distal extremities of the horse: blood gas, serum electrolyte, osmolality, and hematologic alterations. With 120 minutes of pneumatic tourniquet application to the distal extremity in the horse, the following effects were noted in the tourniqueted limb vein (TLV): (i) local venous acidemia, (ii) increase in serum K+ concentrations, (iii) minimal changes in plasma total solids, Na+, or osmolality, and (iv) apparent reduction in hematocrit values when compared with the same measurements in the control leg. Tourniquet release after 120 minutes produced a prompt return to base line for PCV and PO2 in the TLV; however, pH, PCO2 and K+ values in the TLV required 10 to 15 minutes to reach base line (TL...
[Periosteal new bone formation in the horse induced by trauma. (author’s transl)]. The radiological interpretation of periosteal new bone formation in the horse induced by trauma is described and illustrated by some casereports. The better the margins of the new bone can be defined the lesser the activity. The greater the density of the new bone, the longer the duration of time since injury.
The pH/log PCO2 buffer curve of horse blood. Samples of jugular venous blood from six horses were equilibrated with six oxygen and carbon dioxide gas mixtures of PCO2 between 28 and 54 mm Hg. In all six samples the correlations between the pH and the log PCO2 values were linear and highly significant, with r in all six samples greater than 0.985.
It was concluded that the Astrup method for the determination of the acid-base status of the blood of horses is valid.
A case of bilateral hip dysplasia in a foal. Degenerative arthritis of the coxofemoral joints in the Norwegian Dole horse characterised by lameness, erosion of the joint cartilages, deposition of new bone at the attachments of the joint capsules and the teres ligaments, stretching and rupture of the teres ligaments and eventually luxation has been described and is considered to be due to hip dysplasia and to be inherited (Haakenstad, 1953). More recently there have been 2 reports of unilateral degenerative arthritis and subluxation in young horses (Jogi and Norberg, 1962; Davidson, 1967). In the last 8 years there have been 12,051 equine...
Distribution of cardiac output in anaesthetised horses. The radioactive microsphere method was used to determine the distribution of cardiac output in six anaesthetised ponies. Simultaneous measurements of cardiac output allowed calculation of the tissue perfusions (ml/min/100 g). Allowing for the fact that measurements were carried out on animals under halothane anaesthesia and which had respiratory acidosis, the results were comparable with published values for other species.
Pharmacokinetics of ketamine in the horse. Ketamine HCl was administered IV to xylazine HCl-treated horses. The plasma concentration of ketamine was measured several times after administration of the drug and these data were used to develop a two-compartment pharmacokinetic model. The distribution and the elimination phase half-lives averaged 2.9 and 42 minutes. The volume of the central compartment averaged 212 ml/kg of body weight and the volume of the peripheral compartment was approximately threefold larger. The total body clearance of ketamine averaged 26.6 ml/minute/kg. Plasma protein binding of ketamine averaged 50% over the con...
Granular cell tumour (myoblastoma) in the lung of a horse. A granular cell tumour (myoblastoma) occurred in the lung of an aged mare. Multiple greyish-white neoplastic nodules of various sizes almost replaced one lung. Histologically, the neoplasm consisted of small clumps of granular cells in a stroma composed of thick bands of collagen and numerous capillaries. The globoid or stellate neoplastic cells were characterized by a large number of eosinophilic, PAS-positive, diastase-resistant cytoplasmic granules. Ultrastructurally, the granules were of two types: (a) homogeneous, electron-dense granules and (b) multimorphous granules that resembled cell ...
Atypical salmonellosis in horses: fever and depression without diarrhea. Salmonellosis in horses may result in fever, anorexia, and depression without concurrent diarrhea or other obvious gastrointestinal abnormalities and should be considered in cases of fever of unknown origin. The syndrome also is characterized by neutropenia, usually with a left shift, and growth of small numbers of salmonella from feces cultured in selenite enrichment broth. Repeated culturing may be necessary to isolate the organism. All six affected horses of this report recovered in 3 to 7 days without specific therapy.
A preliminary report on the use of warfarin in the treatment of navicular disease. Twenty horses suffering from navicular disease were treated with warfarin given orally. The dosage was to effect, to give a 2 to 4 second prolongation of the one stage prothrombin time (OSPT). Dosage was initially at a rate of 0.018 mg/kg, changing the dose by amounts of 20 per cent until the required dose was achieved. Final dose rates varied from 0.012 mg/kg to 0.75 mg/kg. All the cases treated received warfarin daily throughout the trial. Seventeen of the animals became sound and the remaining 3 showed a marked improvement in their gait. The mean of the ages of the horses was 7.5 years, the...
An equine fetal monster dicephalus tetrapus dibrachius. Double monsters are structurally related to monozygotic twins and the reported frequency of these abnormalities in the equine species is low. Symmetrical, double development in both the cephalic region and caudal trunk was demonstrated along with a common undeveloped cervical mass. Anomalies found in the separate genito-urinary systems added another variant to this case.
Indirect measurement of mean blood pressure in the normotensive and hypotensive horse. Indirect mean arterial pressure was obtained from the tails of 78 anaesthetised and unanaesthetised normotensive and hypotensive horses. Data were obtained to determine the optimum cuff width in relation to tail circumference. A cuff that is too wide under-estimates and a cuff that is too narrow over-estimates blood pressure. With the optimum cuff width, which is slightly in excess of about one-fifth of the tail circumference, indirect mean blood pressure was obtained consistently in normotensive and hypotensive animals with mean blood pressures of 40 mmHg and frequently in animals with pressu...
