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.
Electrical stimulation on skin wound healing in the horse: preliminary studies. The effect of low-level direct-current stimulation on skin wound healing in the horse was assessed. Self-sustaining electrical circuits with electrodes were implanted subcutaneously in or near the wound. Stimulation by direct current (10 or 20 microA) was used to determine the effect on equine skin healing. The efficacy of electrotherapy was evaluated by sequentially comparing the clinical appearance of the wound and measuring the size of the granulating wound bed. The histologic appearance of the healing stimulated wounds was compared with that in nonstimulated control wounds created on 9 hor...
Benzimidazole resistance of equine strongyles: critical tests of several classes of compounds against population B strongyles from 1977 to 1981. From 1977 to 1981, critical tests were conducted on 10 horses naturally infected with population B strongyles. Drugs tested were: oxibendazole (OBZ), 10 mg/kg of body weight (n = 1); albendazole, 10 mg/kg (n = 1); a mixture of thiabendazole (TBZ), 44 mg/kg and trichlorfon, 40 mg/kg (n = 1); a mixture of TBZ at 44 mg/kg with piperazine (PPZ) at 55 mg of base/kg (n = 1); febantel (FBT), 6 mg/kg (n = 3), 12 mg/kg (n = 1), or 24 mg/kg (n = 1); and pyrantel (PRT) pamoate, 6.6 mg of base/kg (n = 1). Large strongyles, Strongylus vulgaris (9 horses) and S edentatus (5 horses), were effectively removed...
Motility of the distal portion of the jejunum and pelvic flexure in ponies: effects of six drugs. Bipolar stainless steel electrodes were surgically implanted in 4 ponies to record myoelectrical and mechanical activity of the distal portion of the jejunum and pelvic flexure. After determining normal activity, the effects of neostigmine, xylazine, flunixin meglumine, dipyrone, panthenol, and atropine sulfate were determined. Flunixin meglumine, dipyrone, and panthenol had no effect on the motility of the jejunum or pelvic flexure. Xylazine and atropine sulfate decreased motility of the distal portion of the jejunum and pelvic flexure, with atropine sulfate having a greater effect and lastin...
Cancellous bone screws for repair of proximal growth plate fractures of the tibia in foals. Proximal growth plate fractures of the tibia in 4 foals were treated surgically. A medial approach was utilized in 3 cases and a lateral approach in the fourth. Bone screw fixation was achieved with cancellous screws and washers. In 3 cases, the screw shaft crossed the proximal tibial growth plate with no adverse effects. In all animals, there was rapid and cosmetic healing. At 8 to 18 months after surgery, all horses were sound at a walk, trot, and canter.
Complications during treatment of traumatic disruption of the suspensory apparatus in Thoroughbred horses. A total of 19 Thoroughbred horses were treated for traumatic disruption of the suspensory apparatus, using either external support of the injured limb, removal of fractured proximal sesamoid bone fragments, metacarpophalangeal arthrodesis, compression screw fixation of the fractured proximal sesamoid bones, application of a cast-brace attached to a transfixation pin inserted through the third metacarpal bone, or combinations thereof. Major complications during the treatment of traumatic disruption of the suspensory apparatus were infection (9 of 19 horses, 47%), large cast sores (10 of 14 trea...
Eosinophils in equine uterine cytology and histology specimens. In a review of specimens from 80 mares with concurrently collected endometrial biopsy and cytology preparations, eosinophils were found in 33 specimens from 27 mares. In 22 of 27 mares, there were conditions predisposing to pneumovagina, which presumably led to pneumouterus. Thirty-two of the 80 mares also had conditions predisposing to pneumovagina but no eosinophils in the uterine specimens. Experimental introduction of air into the uterus of 3 mares resulted in eosinophils in their uterine specimens.
Factors limiting the usefulness of histopathologic examination of skin biopsies in the diagnosis of large animal dermatoses. Skin biopsy for histologic, immunofluorescent, parasitologic, and bacteriologic examination is a common procedure, but for maximum effectiveness the clinician must realize the importance of precautions to select the correct stage of lesion of different diseases; avoiding creating artifacts during removal and fixation; and give full details of history, clinical diagnosis, and differential diagnoses on the laboratory request sheet. Pathology reports describing the subtleties of histologic changes are difficult to write, particularly if the lesions are not specific. Overly long histologic reports...
Borrelia sp. infection in a horse. The clinical signs, response to treatment and features of the spirochaete, Borrelia theileri as was found in a horse with suspected borreliasis are described.
Primary renal cell carcinoma in a horse. A case of primary renal cell carcinoma in a 16-year-old mare is reported. The main presenting signs of chronic weight loss and diarrhoea as well as the initial laboratory examination did not directly indicate renal involvement. Follow-up investigations were strongly suggestive of avain tuberculosis. Further laboratory investigation revealed neoplasia, which was confirmed at autopsy.
Ultrasonic anatomy of equine ovaries. A linear-array ultrasound scanner with a 5-MHz transducer was evaluated for studying follicular and luteal status in mares, and the ultrasonic properties of equine ovaries were characterized. Follicular diameters were estimated in vivo and after removing and slicing six ovaries. Correlation coefficients between the two kinds of determinations were 0.91 for number of follicles >/=2 mm in diameter and 0.95 for diameter of largest follicle. The ovaries of five mares were examined daily until all mares had been examined from three days before an ovulation to three days after the next ovulation....
Active-site titration of horse urinary kallikrein. Horse urinary kallikrein was titrated with the reagent 4-nitrophenyl 4-guanidino-benzoate. The titration was shown to be dependent upon the concentration of the titrant. This finding, which distinguishes horse urinary kallikrein from other enzymes, is explained by the relatively small ratio between its rate of acylation and deacylation (k2/k3 = 16.8) and by a low affinity of the reagent (Km = 1.16 microM). By an appropriate kinetic treatment, it was possible to establish the relationship between the hydrolysis of 4-nitrophenyl 4-guanidinobenzoate and the actual concentration of the active enzy...
Radioisotope bone scanning in horses. The detection of radionuclide activity in the living equine skeleton, using bone seeking radiopharmaceuticals and a hand-held radiation detector, is reported. Pathological changes in bone can be detected and subsequent development monitored. The availability and use of this diagnostic technique in equine practice is discussed.
Vertical migration of infective larvae of equine strongyles in sandy clay loam. The migration of infective strongyle larvae through sandy clay loam soil was determined by evaluating the burial of horse dung as a method of reducing parasitism in horses. Equine feces containing 325 strongyle eggs/g of feces were buried at depths of 2.5, 5.0, 7.5, 10.0, 12.5, 15.0, 20.0, and 30.0 cm below the pasture surface in sandy clay loam soil. Herbage samples were taken periodically from above the buried feces and were analyzed to determine the maximum vertical migration of infective larvae. The greatest distance of migration was 20 cm which occurred 31 days after the feces were buried...
Use of laser light to treat certain lesions in standardbreds. The final and last-quarter race times and racing classes for a group of Standardbreds were analyzed before and after infrared laser light treatment. These horses had either check ligament injuries, plantar desmitis or pharyngeal lymphoid hyperplasia. A 904-nm infrared laser was used to treat check ligaments at 146 Hz for 26 sec/cm2 of affected area, acute plantar desmitis at 73 Hz and chronic plantar desmitis at 292 Hz for 26 sec/cm2 of affected area, and pharyngeal lymphoid hyperplasia at 146 Hz for 5 minutes. Of 35 horses treated for check ligament injuries, 80% had similar or faster final r...
Adenocarcinoma of the intestine in a horse: an unusual occurrence. CARCINOMAS of the small intestine, colon and rectum are relatively rare in domestic animals (Cotchin 1960; Jubb and Kennedy 1970; Meagher, Wheat, Tennant and Osburn 1974; Moulton 1978). A survey of 333 tumours in farm animals revealed 39 horse neoplasms (Misdorp 1967). Twenty-eight of those were from horses in an abattoir survey in which 20,000 horses were slaughtered (an incidence of 0.14 per cent). The remaining 11 were tumours sent in by meat inspectors. Only four of the 39 were present in the digestive system. Two of them were metastasising squamous cell carcinomas in the stomach a...
Fetlock annular ligament desmotomy: a report of 24 cases. Restriction of free movement of the flexor tendons through the fetlock canal results in lameness. The commonest cause was chronic synovitis of the digital sheath. The condition is characterised by an unremitting lameness, synovial distension and a notch on the caudal aspect of the limb. The condition can be relieved by section of the annular ligament of the fetlock. In a series of 24 cases 16 horses returned to work with no recurrence of lameness, three cases were lost to follow up and five animals remained lame; three of these had intercurrent disease.
