Topic:Veterinary Medicine
Veterinary medicine for horses encompasses the study and application of medical practices to diagnose, treat, and prevent diseases in equine species. This field involves a comprehensive understanding of equine anatomy, physiology, pathology, and pharmacology. Veterinary practitioners employ a range of diagnostic tools and therapeutic interventions to address health issues in horses, including lameness, gastrointestinal disorders, respiratory conditions, and infectious diseases. Preventative care, such as vaccination and deworming programs, is also a significant aspect of equine veterinary medicine. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary medicine as it pertains to horses, including advancements in diagnostic techniques, treatment protocols, and preventive health strategies.
Ductuli efferentes in the epididymis of boar, goat, ram, bull, and stallion. Dutculi efferentes were studied by microdissection and histologic methods in 2 boar, 6 goat, 5 ram, 25 bull, and 19 stallion epididymides. On the basis of the present findings and the data of others and relating them to the total number of specimens examined in each species, an estimate (narrow range) was made of the minimal-maximal numbers of efferent ductules as follows: dog 13 to 15; cat 14 to 17; boar 14 to 16; goat 18 to 19; ram 17 to 20; bull 13 to 16; and stallion 14 to 17. The histologic appearance of the efferent ductules of the bull, including measurements of their diameter, lumen, a...
A chronic wasting syndrome in a horse associated with granulomatous enteritis. A case of granulomatous enteritis in a 2 year-old Thoroughbred colt is reported. Clinically the horse showed chronic wasting and subcutaneous oedema of the ventral parts of the body and legs. Grossly the wall of the jejunum and ileum was uniformly thickened. Microscopically the lamina propria, submucosa and the tunica muscalaris of the small intestine were infiltrated with lymphocytes, plasma cells, epithelioid cells and occasional multinucleated giant cells. The granulomatous reaction was most marked in the muscular layers of the gut wall.
[Morphology of live and dead spermatozoa of stallions (author’s transl)]. Examination of 539 ejaculates of stallions of various breeds showed that approximately 60 per cent of the spermatozoa were completely normal morphologically. Of these morphologically normal spermatozoa, 13 per cent were dead. The total proportion of live spermatozoa was 75 per cent, 32 per cent being obviously abnormal (22 per cent of live and 10 per cent of dead spermatozoa). Separated heads (normal as well as abnormal) were significantly more common among dead spermatozoa. Protoplasmic droplets (both at the neck and at the end of the middle piece) were mainly present in live spermatozoa. As ...
Cube colic. "Cube colic" is described and vain attempts to cause the problem on an experimental basis are recorded. It is concluded that not all horses are susceptible to cube colic and if colic occurs in horses being fed on cubes, it is not necessarily due to feeding of cubes. Nomenclature of bowel disorders is considered.
Survey for infection with Onchocerca cervicalis in horses in eastern United States. This survey was performed to study the prevalence of infection with Onchocerca cervicalis in horses in the eastern United States. In the course of the survey, 121 horses, 1 mule and 1 donkey were examined. Microfilariae were recovered from 74 (61%) of the horses examined. All infected horses showed microfilariae of O cervicalis in the umbilical sample, 62 (84%) were infected in the eyelid and, in 36 (49%), microfilariae had invaded the eye. The mule was unifected and the donkey was infected with O cervicalis.
Swimming–a method to study the physiologic response of the horse to exercise. The literature on exercise physiology in the horse with special reference to swimming is briefly reviewed. The use of a pool for swimming horses is described and a technique discussed for the collection of haematologic and haemodynamic data using this form of exercise.
California encephalitis virus activity in mosquitoes and horses in southern Ontario, 1975. A study was undertaken in 1975 to determine California encephalitis virus activity in southern Ontario. Three thousand and sixty-one mosquitoes, primarily Aedes species, were divided into 104 pools and inoculated into suckling mice. Isolates of snowshoe hare virus were obtained from one pool each of Aedes fitchii and A. triseriatus mosquitoes collected in the Guelph area. Serological testing of horse sera revealed extensive virus activity in southern Ontario and indicated that horses may serve as excellent monitors for California encephalitis virus.
Spinal ataxia in the horse. A case report. The purpose of this communication is to report the first diagnosed case of spinal ataxia in the horse in Finland. The horse was atactic and had a wobbling gait. Especially in turning and backing the rear legs tended to swing outwards. Macroscopical studies revealed malformation of the cervical vertebral articular facets and narrowing of the cervical vertebral canal. The vertebral malformation caused the degeneration of the spinal cord, through the compression of the cord. In this paper the macroscopial and microscopical findings are discussed and compared with the findings of other authors.
Myocardial perfusion and function during acute right ventricular systolic hypertension. Hemodynamics, myocardial function, and regional myocardial blood flow (MBF) were measured in 6 closed-chest ponies anesthetized with ketamine hydrochloride before (control) and after creation of acute right ventricular systolic hypertension (RVSH) during normoxia and isocapnic hypoxia. The right ventricular (RV) systolic pressure during each RVSH approached 90 mmHg. There were significant alterations in the pattern of total ventricular MBG distribution in favor of the RV. Because RV myocardium received proportionate increments to its endocardium as well as epicardium, it is concluded that auto...
Pathological features of multiple bone infection in the foal. The gross and histological features of multiple bone infection in two foals are described. In both cases the lesions were confined to the region of the growth plate. Bone and, in some cases, growth plate cartilage destruction has occurred associated with an extensive inflammatory cell infiltration. The significance of the pathological observation is discussed in relation to the pathogenesis of bone infection in the foal.
Hypercalcemia and hypophosphatemia in a mare with renal insufficiency. An 11-year-old mare with polyuria, polydipsia, and azotemia was found to be hypercalcemic and hypophosphatemic. The concentration of calcium in a single collection of urine was within normal limits, although urinary inorganic phosphate concentration was lower than normal. After a brief period of supportive treatment, the mare died. At necropsy, the kidneys were found to be shrunken and fibrous. Histologically, the lesions were those of glomerulonephritis.
