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.
Multiple congenital heart anomalies in five Arabian foals. Five Arabian or half-Arabian foals with suspected multiple cardiac anomalies were examined. Various combinations of clinical examination, electrocardiography, angiocardiography, cardiac catheterization, blood gas analysis, radiography, and echocardiography resulted in clinical data that allowed accurate antemortem diagnoses to be made. In 4 cases, the clinical diagnosis was substantiated by postmortem findings. The confirmed diagnoses were: pseudotruncus arteriosus, a combination of patent ductus arteriosus, pulmonic stenosis, and tricuspid stenosis, pentalogy of Fallot, and tricuspid atresia....
Serum protein electrophoresis in horses and ponies. A method of electrophoresis of horse serum on agarose gels (pH 8.6) is described, together with a system for interpreting changes in the electrophoretic zones based upon the relative distribution of the major serum proteins. Differences in the protein composition of the individual electrophoretic zones of horses and ponies were recorded, although this variation probably reflects differences in management and the presence of subclinical disease.
Experimental equine aflatoxicosis. Adult male Shetland ponies, two per dose level, were given aflatoxin daily at levels of 0.3, 0.15, or 0.075 mg/kg. Signs of toxicosis included inappetence, depression, tremors, and terminal prostration. Deaths occurred at 12 and 16 days (0.3 mg/kg), 25 and 32 days (0.15 mg/kg), and 36 and 39 days (0.075 mg/kg). Prothrombin time, sulfabromophthalein clearance time, total plasma bilirubin, and icteric index increased markedly before death. Elevations in plasma activity of aspartate amino transferase (AST) were observed 1 to 4 days after the start of aflatoxin administration in the high dose grou...
Twinning in mares: A survey of veterinarians and analyses of theriogenology records. Responses of 22 veterinarians to a questionnaire and the records of three brood-mare farms were examined to obtain information on twinning. The incidence rates of multiple ovulations on the three farms were 9%, 11%, and 22%. The multiple ovulation rate was reduced 42-67% in foaling mares compared to barren and maiden mares. Multiple ovulations were significantly more frequent in Thoroughbreds (19%) than in Quarter Horses (9%) and Appaloosas (8%). Both the questionnaire and the farm records indicated a high degree of repeatability of multiple ovulations and twin pregnancies within mares and wit...
Multidirectional in vivo strain analysis of the equine radius and tibia during dynamic loading with and without a cast. Rosette strain gauges were applied to the equine radius and tibia. Three sites were examined on each bone on separate occasions (proximal metaphysis, middiaphysis, and distal metaphysis). At each site, 4 rosette gauges were applied around the bone (ie, cranial, caudal, medial, and lateral). Strain recordings were made while walking the horse with and without a full-limb plaster cast. The principal axis of tensile strain was on the craniolateral aspect of the radius. Distally, on the radius, the largest strains were torsional. The cast changed the principal axis of tensile strain on the radius ...
Dermatitis in horses and man caused by the straw itch mite. An episode of dermatitis in 12 horses and many animal handlers in the Veterinary Medical Teaching Hospital of the University of Florida was attributed to the straw itch mite, Pyemotes tritici. The mite was found in abundance alfalfa hay that recently had been delivered to the hospital. Papules were the most common cutaneous lesions, and these developed on areas of the body to which the mites had easiest access. The clinical course was self-limiting, remitting when the hay supply was depleted.
Effectiveness of ivermectin against later 4th-stage Strongylus vulgaris in ponies. Twelve pony foals were reared worm-free and inoculated with Strongylus vulgaris. Approximately 8 weeks after they were inoculated, 6 foals were given ivermectin IM at a dosage rate of 200 micrograms/kg of body weight and 6 were given a placebo. All foals were necropsied 35 days after treatment. Ivermectin was 98.9% effective in eliminating later 4th-stage S vulgaris larvae located near the origin of major intestinal arteries and in reducing clinical signs and permitting resolution of lesions associated with verminous arteritis. One pony foal reared on pasture and with evidence of arteritis of ...
The onset and consequences of tarsal bone fractures in foals. Fractures of the central tarsal and/or third tarsal bones involving both limbs of six foals are described. Five of the subjects were born either premature or of twin pregnancies. Fractures occurred in the neonatal period and coincided with disablement. Features of behaviour, posture and gait are described, together with gross radiographic findings, bone ash determination and blood chemistry. Lesions observed on the articular faces of tarsal bones recovered from adult horses may have originated during the neonatal-period.
Electrophysiologic studies of the thoracic limb of the horse. The cutaneous innervation of the thoracic limb was investigated in 18 barbiturate-anesthetized horses, using electrophysiologic techniques. The cutaneous area (CA) innervated by each cutaneous nerve was delineated in at least 4 horses by stroking the hairs with a small watercolor brush while recording from the nerve. Mapping of adjacent CA revealed areas of considerable overlap. The part of a CA of a given nerve supplied only by that nerve is referred to as its autonomous zone (AZ). In contrast to the standard textbook illustrations cutaneous branches of the axillary, radial, musculocutaneous,...
