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.
Isolation and characterization of beta- and gamma-caseins from horse milk. Three groups of casein components were isolated from horse milk. Group I is almost insoluble at acid and neutral pH, and is rather heterogeneous on alkaline gels with or without sodium dodecyl sulphate. Group II shows strong similarity to beta-casein from other species, as concluded from its amino acid composition and its N- and C-terminal sequences. This group consists of five electrophoretically distinguishable forms, all containing ester phosphate groups but no carbohydrate. Group III is composed of C-terminal fragments of the beta-like (group II) fraction and probably arises from the actio...
Phenoxybenzamine for the treatment of severe nonresponsive diarrhea in the horse. Phenoxybenzamine, an alpha adrenergic antagonist, was administered IV to 6 clinically normal horses, 5 horses with experimentally induced diarrhea, and 7 horses with naturally-occurring diarrhea. It was established that a total of 2 mg of phenoxybenzamine/kg of body weight given in divided doses resulted in alpha adrenergic blockage of approximately 72 hours' duration, tranquilization, and mild constipation in the normal horse. The 5 experimental cases of diarrhea were involved in a laminitis research protocol in which laminitis was induced by oral carbohydrate overload. In all 5 of those case...
Paradoxic hypercalcemia and hypophosphatemia associated with chronic renal failure in horses. Chronic renal failure associated with hypercalcemia and hypophosphatemia was diagnosed in 6 horses. The renal lesions in 5 of the horses were classified as chronic glomerulonephritis and in the sixth, as chronic interstitial nephritis/pyelonephritis. There was no evidence of primary hyperparathyroidism or pseudohyperparathyroidism, thus suggesting that hypercalcemia associated with advanced renal failure in horses is related to a unique role of the equine kidney in calcium homeostasis.
Complications of cleft palate repair in large animals. Seven foals, 2 horses, and 2 calves were presented to the George D. Widener Hospital for Large Animals at New Bolton Center and the Large Animal Clinic at Auburn University for surgical repair of cleft palate. All animals had preexisting pneumonia. Initial repair of cleft palate in 6 foals, 2 horses, and 2 calves was performed via mandibular symphysiotomy. Primary repair of cleft soft palate in a foal was attempted through a pharyngotomy incision after fracture of the basal hyoid bone; however, exposure was inadequate and mandibular symphysiotomy had to be done. Dehiscence of a portion of the ...
Retropulsion-propulsion in equine large colon. The circular and longitudinal muscle coats of equine "midcolon" were found to be directly electrically coupled. They appear to act in concert, in healthy animals, as a pacemaker in the area of the large colon pelvic flexure, for retropulsive-propulsive myoelectrical events. The retropulsive events keep the cecum and right ventral and left ventral divisions of the colon filled, imposing a delay time for fermentation of cellulose and for bacterial protein synthesis. Point-to-point involvement of adjacent colon sections was slowed by cooling the intestinal contents with no adverse clinical signs....
Renal dysfunction in a case of purpura haemorrhagica. A four-year-old thoroughbred was presented with clinical manifestations of purpura haemorrhagica. Evidence of renal involvement consistent with glomerulopathy and nephrotic syndrome, characterized by heavy proteinuria and azotaemia, became apparent and may have been exacerbated by diuretic therapy. Autopsy revealed membrano- and mesangial proliferative glomerulonephritis and chronic pleuritis. Circulating immune complexes may have been responsible for the renal diseases and the purpura.
Use of a gold compound for the treatment of pemphigus foliaceus in a foal. A 4-month-old foal was examined because of generalized exfoliative dermatitis, with thick scales, extensive crusting, and oozing of serum. A diagnosis of pemphigus foliaceus was made by histologic and immunopathologic examinations of skin biopsy specimens. The foal was treated with a gold compound, aurothioglucose (1 mg/kg once weekly for 14 weeks). For the initial 5 weeks, high-dose glucocorticoid treatments also was used. The skin disorder resolved entirely after 12 weeks of treatment.
Detection of equine infectious anemia virus in a horse with an equivocal agar gel immunodiffusion test reaction. A horse whose serum reacted equivocally in the agar gel immunodiffusion (AGID) test for equine infectious anemia was studied over a 3-year period. The horse remained afebrile and virus was detected in only 1 of 6 horse inoculation tests. The intensity of AGID test reactions increased temporarily following this evidence for virus. Although the AGID test reaction was equivocal and 5 of the 6 transmission attempts failed, the 1 successful transmission proved the horse was infected.
Rn for treatment of periocular fibrous connective tissue sarcomas in the horse. Twelve periocular fibrous connective tissue sarcomas in 11 horses were treated with 222Rn. Follow-up periods ranged from 1 to 6 years; the overall nonrecurrence rate at 12 months after therapy was 92%. Two lesions recurred 2 years after treatment, and 1 after 3 years. One of the former lesions has not recurred after a 2nd 222Rn treatment.
A mild form of strangles caused by an atypical Streptococcus equi. A mild form of strangles caused by an atypical Streptococcus equi was recognized on a large horse breeding farm. The organism differed from most S equi isolates by disappearance of the mucoid capsule by 24 hours of culture, leaving a matt-type colony. Typically, the clinical signs were a transient (24-48 hour) fever, profuse nasal discharge, and anorexia. In about half the affected animals, there was moderate mandibular lymph node enlargement, and these glands usually ruptured or were drained. The use of a passive hemagglutination antibody test showed that subclinical infection was widespread ...
Pedal bone rotation as a prognostic sign in laminitis of horses. We reviewed 91 cases of laminitis in horses admitted to the Michigan State University Veterinary Clinical Center between Jan 1, 1973 and Dec. 30, 1978. From information in the case records and from the results of a telephone questionnaire, cases were classified into 4 categories on the basis of return to athletic function. The degree of pedal bone rotation was inversely correlated with return to athletic performance. Horses with less than 5.5 degrees rotation returned to former athletic function, whereas horses with more than 11.5 degrees rotation lost their use as performance animals. Ponies ...
Hemolytic anemia in horses after the ingestion of red maple leaves. Signs of acute hemolytic anemia developed in 4 adult horses from 2 Georgia farms 3 to 4 days after the ingestion of wilted leaves from cut red maple trees (Acer rubrum). Clinical findings included weakness, polypnea, tachycardia, depression, icterus, cyanosis, and brownish discoloration of the blood and urine. Blood changes included methemoglobinemia, free plasma hemoglobin, decreased pcv, and Heinz bodies in erythrocytes. These findings plus hemoglobinuria suggested intravascular hemolysis. Three of the 4 horses diet 5 to 7 days after ingestion of the leaves. Gross pathologic changes included...
Ileocolonic aganglionosis in white progeny of overo spotted horses. The congenital absence of myenteric ganglia in the terminal portion of the ileum, cecum, and entire colon of white foals with overo spotted parents was reported. Males as well as females were affected. The foals were generally normal at birth but did not defecate. Signs of colic were noticed between 5 and 24 hours after birth, with death occurring at 23 to 132 hours.
Osseous cyst-like lesions of the medial femoral condyle in the horse. Osseous cyst-like lesions of the medial femoral condyle were found in 32 horses admitted to the University of Pennsylvania between 1971 and 1978. Sex or breed predilection was not found. In 12 horses, osseous cysts were found in both hindlimbs. Of the 25 horses on which follow-up information was obtained, 16 became sound and useful between 4 months and 1 year after diagnosis. Horses that became lame before 3 years of age had a better chance for later soundness. Horses that became sound had significantly smaller cysts than those that remained lame.
