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.
Coronary arterial anatomy of the small pony. Ventricular weights and coronary arterial distribution and diameters were determined in 10 small adult ponies (139 +/- 32 kg). Combined ventricular weights averaged 0.52% of the body weight, with an average of 77% of the total ventricular weight being the left ventricle. The pony is right coronary predominant, with the interventricular subsinusoidal branch of the right coronary artery and interventricular paraconal branch of the left coronary artery providing comparable blood supply to the left ventricular free wall and septum.
The efficacy of fenbendazole in the control of immature strongyle infections in ponies. The efficacy of fenbendazole against immature stages of Trichonema spp., Strongylus vulgaris and Strongylus edentatus was evaluated. Naturally infected 6 to 12 month old ponies were given single, oral doses of 0, 15, 30 and 60 mg/kg of body weight. A dose response relationship was noted between increasing dose levels and efficiency against larval trichonemes and migrating stages of S. vulgaris and S. edentatus. Dose levels of 30 mg/kg and higher removed 93 per cent of mucosal stages of Trichonema spp., while doses of 60 mg/kg removed 83 per cent and 89 per cent of the migrating larvae of S. vu...
Enflurane, halothane, and isoflurane potency in horses. The minimal alveolar concentration of anesthetic required to prevent gross purposeful movement in response to electrical stimulation of oral mucous membranes was determined in horses for 3 agents. Equipotent concentrations of enflurane were 2.12 volumes %; of halothane, 0.88 volumes %; and of isoflurane, 1.31 volumes +. The alveolar concentration required to produce at least 60 seconds of apnea was also determined for these agents. From these data and the minimal alveolar concentration information, anesthetic indices were determined for each agent. The indices for enflurane, halothane, and iso...
Experimental Parascaris equorum infection of foals. Six worm-free pony foals, two to four months old, were infected with parascaris equorum eggs using three different dosage regimes and killed at either 40 or 95-100 days after infection. Coughing and a circulating eosinophilia were features of large infections from which only a small number of worms developed to maturity. In small infections a high percentage of the parasites matured in the small intestine and this was associated with unthriftiness. Pre-patent periods of 80 and 83 days were recorded.
Some problems associated with intestinal surgery in the horse. The paper considers the general principles of intestinal surgery in the horse and illustrates a theatre layout suitable for this purpose. The problems of locating and reducing obstructions of the small and large intestine are discussed, with particular emphasis on incarcerations of the small bowel and the techniques of jejunal and ileal re-implantation after bowel resection.
Coprophagia as seen in thoroughbred foals. Four Thoroughbred foals were seen to quickly eat part of the faeces deposited by their own dams on some 40 per cent of the mare-defaecating occasions observed between the second and fifth week after birth. They did not do it before or after this period. This behaviour was thought to be a feeding pattern which formed a normal part of the foal's development.
Phenylbutazone and the horse–a review. The clinical uses and side-effects of phenylbutazone in man, horses, and other animals are reviewed. The blood dyscrasias commonly described in man have not been reported in the horse, although several of the more minor side-effects have occasionally been seen (e.g. water retention, depression, transient staggering and phlebitis). Despite the lack of documented evidence, the toxicity of phenylbutazone in the horse is considered to be lower than that in man. This may be associated with the lower dose rates normally used, the more rapid plasma clearance rate and the comparatively younger age of ...
Bone growth in foals and epiphyseal compression. Limb angulation in foals may be due to defects in epiphyseal growth plates. The present state of knowledge concerning rate of growth in foals and differences in growth of different epiphyseal plates is reviewed and the importance of accurate knowledge of these parameters in treatment of angulation by unilateral retardation of an epiphyseal growth plate is stressed. Retardation of epiphyseal plate growth by compression wiring is described and its advantages in comparison with staplings are suggested. Compression wiring was used in 3 cases in which age, bone width and the degree of angulation we...
Western equine encephalomyelitis in horses in the Northern Red River Valley, 1975. In mid-July, 1975, western equine encephalomyelitis (WEE) virus was isolated from mosquitoes collected in flooded areas of eastern North Dakota and western Minnesota. Inasmuch as clinical manifestations of WEE are usually observed in horses before human cases of encephalitis are recognized, surveillance of equine disease was initiated. Sixty-one practicing veterinarians from the are under surveillance reported 281 cases of WEE in horses from June through September, with peak incidence in late July. The high percentage of sero-positive, clinically normal, unvaccinated horses in one region sugge...
Epidural melanoma causing posterior paresis in a horse. An aged gray stallion was examined because of fullminating posterior paresis, bladder paralysis, and perineal anesthesia. Lower motor neuron dysfunction was detected at the lumbosacral level of the spinal cord, and cerebrospinal fluid was yellow. After brief supportive treatment, the horse died. Necropsy revealed a single epidural melanoma at L5-6. The absence of cutaneous melanotic growth, absence of organ involvement, and extensive vertebral remodeling indicated the neoplasm to have been primary and to have been present for an extended period. Neurologic dysfunction was acute and progressive...
Diaphragmatic hernias in the horse: a review of the literature and an analysis of six additional cases. Eighteen cases of equine diaphragmatic hernia were reviewed. Most of the cases were of long duration, with an additional factor precipitating acute abdominal crisis. History and physical examination were of little diagnostic significance. Radiography, if available, and exploratory laparotomy were the most useful diagnostic procedures. The prognosis for successful surgical repair and recovery was poor.
Control of equine infectious anemia in horses in Hong Kong. Equine infectious anemia (EIA) has been enzootic in Hong Kong since the end of World War II. In 1972, a serologic survey of the horses at the Hong Kong Jockey Club indicated 23% prevalence of EIA. Disease control measures were instituted, and the spread of infection was reduced. In 1976, the prevalence of EIA was believed to be sufficiently low to implement procedures for eradication of EIA from all horses in Hong Kong. A correlation between EIA and poor performance of racehorses was demonstrated.
The use of hormones in reproductive management of the mare. A brief review is presented of the use in equine veterinary medicine of anterior pituitary hormones, posterior pituitary hormones, placental hormones, steroid hormones and prostaglandins. These hormones are used frequently in clinical application without a scientific basis for their expected activity.
Surgical treatment of an unusual fracture of the first phalanx of a horse. A 3 year old thoroughbred colt in full training pulled up
acutely lame during a training gallop on a dirt track.
According to the trainer no reason for the injury was
evident. The horse refused to bear weight on the leg
and when forced to walk back to the stables it would
only touch the affected toe to the ground. The fetlock
soon became swollen and was very painful. The trainer
treated the animal for a sprain with ice packs and
bandages. No improvement occurred in 72 hours and
veterinary advice was sought.
Examination revealed the horse to be in obvious
pain. He was unable to bear ...
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.
