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.
[Several physiologic aspects of the reactions of foals in the first three days after weaning]. Changes have been observed in nine foals, six months of age, after weaning for the time of three days, namely in the intake of drinking water, hematocrit, sedimentation of erythrocytes and three minerals Na+, K+ and Cl-. Foals respond to weaning immediately, lowering significantly their consumption of drinking water and increasing high significance of Na+ and Cl-. Changes of level K+, hematocrit and sedimentation don't show any significant variations. The results reached are to be considered as an introductory information for further inquiry on the more extensive methodical basis.
Equine motor neuron disease; a preliminary report. A spontaneous motor neuron disease or neuronopathy was identified in 10 horses from the northeastern United States. Signs of generalized weakness, muscle fasciculations, muscle atrophy and weight loss progressed over 1 to several months in young and old horses of various breeds. Pathologic studies revealed that degeneration and loss of motor neurons in the spinal cord and brain stem resulted in axonal degeneration in the ventral roots and peripheral and cranial nerves and denervation atrophy of skeletal muscle. Many spinal neurons were swollen, chromatolytic and contained neurofilamentous accu...
Two rare cutaneous neoplasms in horses: apocrine gland adenocarcinoma and carcinosarcoma. Two rare equine cutaneous neoplasms, an apocrine gland adenocarcinoma and a carcinosarcoma were diagnosed in a 17-year-old pony and a 14-year-old mare, respectively. The apocrine gland adenocarcinoma was present on the prepuce. Histologically, papillary projections of low cuboidal to columnar epithelial cells were generally well differentiated, and surrounded dilated acini. Stromal invasion was present, but vascular and lymphatic invasion was not seen. The carcinosarcoma was present in the right flank of the mare. Two discrete cell populations were characterized histologically. One portion of ...
Neospora caninum (Apicomplexa) in an aborted equine fetus. Tachyzoites of Neospora caninum were found in sections of lung of an equine fetus aborted 2 mo before term. Individual tachyzoites were approximately 3-5 x 2-3 microns, divided by endodyogeny, and stained positively with anti-N. caninum serum but not with anti-Toxoplasma gondii serum. Toxoplasma gondii antibody was not found in the mare's serum. This is the first report of N. caninum in a horse and indicates that N. caninum can be transmitted transplacentally in equids.
Echocardiographic detection of an intact aneurysm in a horse. Two-dimensional real-time echocardiographic examination of a 3-year-old Thoroughbred gelding with pleuropneumonia revealed an intact aneurysm of the right sinus of Valsalva, which was confirmed at postmortem examination. The horse had no clinical signs associated with the aneurysm.
Surgical stapling for repair of a rectal tear in a horse. A grade-4 rectal tear in a mare was successfully repaired per rectum, using a surgical stapling device. The mare had only minor postoperative complications. This technique has some advantages over previously described procedures, but should be reserved for use in selected cases.
Subcutaneous part of the masseteric ramus of the external carotid artery as a proposed site of pulse-taking in Thoroughbreds. The subcutaneous part of the masseteric ramus of the external carotid artery can be used as a proposed site of pulse-taking in most Thoroughbreds. It is located on the lateral surface of the masseter muscle, and its contour may be visible in association with a summer coat.
Vacuum phenomenon in the metatarsophalangeal joint of a horse. Vacuum phenomenon was induced inadvertently during radiographic examination of a metatarsophalangeal joint of a lame horse. The phenomenon was recreated in a sound horse when a metacarpophalangeal joint was radiographed in a stress-flexed position. Distraction of apposing articular surfaces may induce the vacuum phenomenon, which could result in misdiagnosis of an osteochondral defect or fracture.
Malignant melanoma in the foot of a horse. A 24-year-old horse had a malignant melanoma of the right forefoot. Because surgical excision of the melanoma was incomplete, as determined by histologic examination of the excised tissue margins, the tumor margins were injected with a matrix therapeutic implant containing cis-diamminedichloroplatinum, epinephrine, and purified bovine collagen matrix. The foot healed and the horse remained clinically free of disease for 26 months before recurrence of malignant melanoma. Surgical exploration of the digit revealed extensive involvement of the foot, and the horse was euthanatized.
Prekallikrein deficiency in a family of Belgian horses. A 7-year-old Belgian stallion hemorrhaged excessively after castration; the hemostatic mechanism was investigated. The horse had normal one-stage prothrombin time and markedly prolonged activated partial thromboplastin time (APTT). Results of intrinsic coagulation factor assays were all normal with the exception of prekallikrein activity, which was markedly reduced (less than 1% activity; value for control population, 63 to 150%). Two of this horse's full siblings, a brother and sister, had markedly prolonged APTT and low prekallikrein values (2.5% and less than 1%, respectively). The addition...
Variable locations of nutrient foramina of the proximal phalanx in forelimbs of Thoroughbreds. Bilateral metacarpophalangeal radiographs of 100 Thoroughbreds were examined for visualization and location of the major nutrient foramen of the proximal phalanx. The foramina were located on the dorsal or palmar aspects of the cortex or were not visible radiographically. Of the 100 horses, 60 had the same pattern in both forefeet. In the remaining 40 horses, the left and right proximal phalangeal foramina were asymmetric. Of the 200 proximal phalangeal foramina (100 horses), 53 were on the dorsal aspect of the cortex and 101 were on the palmar aspect of the cortex; 46 were not visible radiogr...
Ocular neoplasms of vascular origin in the horse. HAENIANGIOMAS and haemangiosarcomas are neoplasms of probable vascular origin that occur rarely in the equine eye in a survey there were 21 cases of vascular neoplasia in the skin of horses, and the prevalence of these two tumours was estimated to be 0.25 and 0.02 percent respectively (Hargis and McElwain 1984). Their incidence is likely to be less in the eye than in the skin and in two surveys of equine ocular tumours there is only brief mention of two hacnumgiasarcomas. one involving the lid (Morgan 1969), the other the orbit and lower eyelid (Lavach and Severin 1977). Only two cases of hacm...
Plasma histamine levels during exploratory laparotomies in suspected equine grass sickness cases. The research article discusses an investigation into how exploratory diagnostic laparotomy affects the circulating histamine levels in acute, subacute, and chronic suspected equine grass sickness cases. The study utilized a […]
Bacterial epididymitis in two stallions. Two stallions had unilateral bacterial epididymitis attributable to S zooepidemicus infection. Diagnosis was based on bacterial isolation, WBC in the semen, higher than normal blood fibrinogen concentration, and leukocytosis with regenerative left shift. One horse had high seminal pH. Ultrasonography of the involved epididymides revealed changes consistent with the appearance of abnormal accumulation of exudate in the tail of the epididymis. Treatment included unilateral orchiectomy and antibiotic administration. In stallion 1, the infection persisted despite treatment. Treatment result was no...
