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.
Male uterus in the donkey and horse. The anatomy and histology of the male uterus were studied in the donkey and the horse. In the former it was found complete and long, while in the latter it was incomplete or absent. Some variations met with are described. A new concept of "internal male hermaphroditism' is presented and two types are differentiated.
The influence of neuroleptanalgesia on the serum activity of muscle enzymes in ponies. The serum activities of creatine kinase (CPK), aldolase (ALD) and alpha-hydroxybutyrate dehydrogenase (HBD) were determined in a group of Welsh Mountain ponies before and after a 30 minute period of neuroleptanalgesia induced by i.v. injection of Immobilon and terminated by i.v. injection of Revivon. There were slight but significant increases in the serum activities of CPK and HBD following neuroleptanalgesia, but no change in the serum activity of ALD. It is suggested that this form of neuroleptanalgesia may be associated, in ponies, with a degree of reversible myocardial hypoxic change, pos...
The null allele in the horse esterase (Es) system detected by enzyme assay and rocket immunoelectrophoresis in heterozygous animals. The detection of the recessive null allele of horse serum esterase (Es) is possible in heterozygotes Es+/EsO which by starch gel electrophoresis appear like homozygotes Es+/Es+. Two methods are proposed, the titration of enzymatic activity of esterase and the immunochemical titration of esterase as antigen. These methods can be applied to solve the cases of suspect parentage or in population studies.
Antibodies to Akabane virus in Australia. Neutralising antibody to Akabane virus was shown to develop in cattle in northern Australia throughout the year and also on the east coast of New South Wales in the summer during 1975/1976. Other species found to have antibody to Akabane virus were buffaloes, horses, camels and sheep, but no antibody was found in domestic chickens, ducks, wallabies or man. The biting midge Culicoides brevitarsis has been detected in all the major areas where antibody was demonstrated in this study.
Bending properties of cortical bone of the horse. Bending properties of samples of cortical bone taken from the cranial, caudal, medial, and lateral quadrants of the midshaft of the radius, femur, and metacarpus of 12 ponies, 18 months old, were determined by 4-point loading at a rate of 10 mm/minute. The elastic modulus for all samples was between 16.2 and 20.2 GN/m2, and the ultimate breaking strength, between 204 and 255 MN/m2. There was greater variation in these properties between bone quadrants than between bones. Samples from the cranial and medial quadrants of both femur and radius were stiffer and had greater ultimate breaking streng...
Proprioceptive innervation of the external cremaster muscle of some domestic mammals. The proprioceptive innervation of the external cremaster muscle of some domestic animals was studied. Muscle spindles and tendon organs with their well-known features were found, but this finding was uncommon and unexpected in the investigated animals. For this reason, we believe that there is no relationship between the presence of these proprioceptors and the cremasteric reflex.
The development of a radio-stethoscope for use in the horse at rest and during exercise. The development of a radio-stethoscope for horses is described. The equipment consisted of a sound transducer applied to the skin adjacent to the trachea and a radio transmitter attached to the saddle. The signals emitted were detected by telemetry and recorded on a magnetic tape-recorder. The recorder incorporated a monitor earphone so that sounds could be reproduced at the time of recording. The frequency response obtainable ranged from a few Hz to 4 KHz. This technique provided an objective means of studying the respiratory sounds generated during exercise although absolute values could not...
Germ cell proliferations in the fetal horse ovary. During the 340 day pregnancy of the horse, the germ cells in the fetal ovary showed a meiotic prophase which began in days 60-70 and might be prolonged after day 200. Three or four successive oogonial mitotic proliferations passed into the meiotic prophase but the great majority of the oocytes first involved degenerated, and no appreciable numbers of primordial follicles were left behind. At 150 days of pregnancy and again at 197 days, oocytes in early meiotic stages filled the ovarian cortex. Primordial follicles were present, but rare. As the prophase gradually came to an end, groups of oocy...
Vestibular disease, and its relationship to facial paralysis in the horse: a clinical study of 7 cases. The signs observed in 6 cases of peripheral vestibular disease included incoordination, head tilt and nystagmus. The intensity of the signs varied greatly with duration of the disease, and in 3 cases facial paralysis was also present. Tympanosclerosis was demonstrable in all cases subject to radiology. Trauma was the causative factor in most cases. The causes of, and relationships between, vestibular dysfunction and concomitant facial paralysis are discussed. The exact etiology of the tympanosclerosis is unknown.
Black grain mycetoma (maduromycosis) in horses. Black grain mycetoma occurred in two horses, one a cross-bred pony and the other a Thoroughbred racehorse. Lesions were limited to wart-like growths in one case and a deep-seated girth gall in the other. In both cases the granules in the affected tissues were similar in pigmentation and structure to those produced by Curvularia geniculata in dogs. Since all the specimens were received in formalin, the causative fungus could not be isolated. These are the first cases of maduromycosis in animals to be recorded in South Africa.
Regional blood flow to the stomach and small intestine in ponies. Studies on regional blood flow to the stomach and small intestine were performed in 9 anesthetized ponies. Carbonized microspheres (15 +/- 5 micron in diameter) labeled with 85Sr were injected into the left atrium to determine blood flow distribution. In 4 ponies, the regional flows to mucosal-submucosal layers of the stomach and the small intestine were also measured. The nonglandular region of the stomach received the least blood per 100 g of tissue, and the duodenum received the greatest. The regional blood flow to the duodenum was significantly higher than that to the glandular stomach reg...
