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.
Cryotherapy of periocular squamous cell carcinoma in the horse. Squamous cell carcinoma around the eyes of 3 horses was treated with liquid nitrogen, using cryotherapy probes as the method of application. In 2 cases, there was complete regression of the tumor; in the 3rd case, remission and relief of discomfort were temporary.
Amphotericin B for the treatment of localized subcutaneous phycomycosis in the horse. Amphotericin B was used systemically or locally, or both, in the treatment of localized subcutaneous phycomycosis in horses. In 8 of 10 cases, the results were satisfactory. Intravenous treatment was well tolerated at an average starting daily dosage of 0.38 mg/kg, increasing up to as high as 1.47 mg/kg. It was concluded that the ideal treatment regimen would include early surgical removal of the lesion followed by daily intravenous and topical administration of amphotericin B, with periodic extirpation of small necrotic tracts as necessary.
Observations on development of Strongyloides westeri in foals nursing dams treated with cambendazole or thiabendazole. In 1 experiment, a prepatent period of 8 or 9 days was recorded for Strongyloides westeri in 4 pony foals raised worm-free but infected with parasitic 3rd stage larvae in the postpartum milk of a mare via gastric intubation. This is about 2 to 6 days less than the usual age that eggs of S westeri appear in the feces of naturally infected suckling foals, in central Kentucky.
In other studies, mares were treated with cambendazole or thiabendazole at 0 to 2 days after parturition and continued for 7 to 16 days. Appearance of S westeri eggs in feces of foals nursing treated mares was prevented ...
Renal coccidiosis of the horse associated with Klossiella equi. Klossiella equi in the kidney of a horse is described. Gametocytic and sporogonic stages were observed in the epithelium of the collecting tubules in association with schizonts in the glomeruli and proximal convoluted tubules. The condition was asymptomatic and caused only minor renal damage and inflammation.
Failure of colostral immunoglobulin transfer as an explanation for most infections and deaths of neonatal foals. Failure in colostral immunoglobulin G (IgG) transfer was found in 9 of 87 Thoroughbred foals. Seven (78%) of these 9 foals acquired infections requiring therapy. Twelve of the foals had partial failure in colostral IgG transfer, and 3 of these had infections requiring therapy. The remaining 66 foals had normal transfer of colostral IgG, and only 2 had detectable infections. The failure of colostral IgG transfer was attributable to nursing problems in only one case. When presuckle postpartum colostrum was collected, 2 of 4 failures of colostral IgG transfer and 4 of 6 partial failures of colost...
Equine herpesvirus 1 infection of horses: studies on the experimentally induced neurologic disease. Experimental infection with equine herpesvirus 1 (rhinopneumonitis) resulted in neurologic disease in 8 of 15 inoculated horses. Nonpregnant animals did not develop clinical disease, and microscopic examination of tissues revealed no changes. In all mares between 3 and 9 months of gestation, a neurologic syndrome appeared 6 to 8 days after inoculation. Mares inoculated when 10 months pregnant did not develop neurologic disorders, but several aborted. The histopathologic change common to both sequelae was vasculitis, involving smaller arteries and veins. Although blood vessel changes were detec...
Physical optics of the equine eye. The equine eye was treated as a general lens system and calculations were done to determine image position in relation to the retina for objects at a distance of infinity, 100 m, and 1 m. The retina is 19.1 mm behind the posterior surface of the lens; therefore, the image appears 14.6 mm posterior to the retina at infinity and at 100 m, and 16.3 mm at 1-m distance on a horizontal axis. The animals studied were hyperopic. It is evident that the horse must move its head or eye, or both, for optimal visual acuity. At the same time, some objects in the total field of vision are imperceptible or in...
Cardiac output, left ventricular ejection rate, plasma volume, and heart rate changes in equine laminitis-hypertension. Acute laminitis-hypertension was produced experimentally by carbohydrate overloading of the gastrointestinal tract in 8 horses, and the resulting hemodynamic changes were measured. Statistically significant (P less than 0.01) increases in cardiac output, left ventricular ejection rate, heart rate, and arterial pressure were related to statistically nonsignificant changes in peripheral resistance and a delayed (Obel grade 3 plus 24 hours) decrease in plasma volume. When compared with control values, the doubling of cardiac output and left ventricular ejection rate simultaneous with little or no...
The outbreak of equine influenza in England: January 1976. Equine influenza type 2 infections occurred in the Newmarket areas in January 1976. The disease did not spread to any extent and while this may have been due to recent vaccination it was found that not all vaccinated horses were fully protected. The virus involved showed some antigenic drift from the prototype strain A/equine/Miami/1/63 (Heq 2 Neq 2).
Laboratory methods of equine pregnancy diagnosis. Rectal examination is a reliable method of diagnosing pregnancy in the mare. Also, test kits are available for the simple quick detection of pregnant mare serum gonadotrophin. Nevertheless there is a considerable demand by practitioners for an independent laboratory service in equine pregnancy diagnosis, particularly during the gestational phase when placental gonadotrophin is concentrated in the blood. An initial attempt to provide a service by means of the agar gel diffusion test was disappointing and alternatives were sought. The primary requirements for an ideal alternative technique were ...
Flow rates from an intermittent positive pressure breathing-anesthetic delivery apparatus for horses. Inspiratory flow rates were measured and compared in an equine intermittent positive pressure breathing-anesthesia delivery apparatus powered by a positive phase ventilator, a positive-negative phase ventilator, and a modified positive phase ventilator with automatic flow acceleration at driving pressures of 2,600, 4,400, and 5,200 mm of Hg (50, 85, and 100 psi). The last-named apparatus consistently produced the highest flows for a given ventilator setting and driving pressure. Regardless of the unit used, the greater driving pressures and high ventilator range settings produced the greatest ...
