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.
The applied pharmacology of azaperone in ponies. The butyrophenone tranquilliser, azaperone, was administered intramuscularly to ponies in five series of experiments, using a dose level of 0-4 mg/kg once and 0-8 mg/kg four times. An excellent or good sedative effect was usually obtained with both dose levels, but the response was more consistent with the higher dose. The onset of sedation was apparent within 10 min of administration, the maximal effect usually occurring between 20 and 60 min while sedation was no longer apparent after 2 to 6 h. Body temperature was reduced in all animals for at least 2 h and respiratory rate was increased in...
Neuropathological changes associated with the neonatal maladjustment syndrome in the thoroughbred foal. A neuropathological investigation was carried out on the brains of 18 foals suffering from the neonatal maladjustment syndrome and results were compared with those obtained from the brains of nine foals dying from other causes. Necrosis of the cerebral cortex of an ischaemic nature was found in nine of the neonatal maladjustment foals, frequently accompanied by local haemorrhage. In three of this group of foals there was also necrosis in the diencephalon and brain stem. In the brains of the nine other affected foals there was haemorrhage in the cerebrum and sometimes in the brain stem and cere...
Clinical evaluation of blood lactate levels in equine colic. Blood lactate levels were evaluated in 36 horses (43 cases) presented with colic. A correlation between increasing blood lactate levels and decreasing percentage survival has been shown. An appreciable anion gap was found in 7 of 10 cases analyzed in detail but in each case the entire gap could not be accounted for by lactate alone. Proposals are offered to account for the unmeasured anions. Blood lactate determination is suggested as a prognostic rather than a diagnostic aid for the equine practitioner and should be used to augment other clinical findings in the horse exhibiting colic.
Critical tests with oxibendazole against gastrointestinal parasites of ponies. Twenty ponies were allotted to 4 groups of 5 ponies each, and oxibendazole was orally administered at dose levels of 5, 10, 15, and 20 mg/kg. In the 3 groups of ponies given the largest doses, efficacy against 3 species of Strongylus was between 92 and 100% and that against small strongylids of the genera Cyathostomum, Cylicocyclus, Cylicodontophorus, and Cylicostephanus was more than 99%. All adults and 95 to 100% of larvae of the pinworm Oxyuris equi were removed. In the group of ponies given 5 mg/kg, 86 to 100% of the large strongylids and 84 to 100% of the small strongylids were removed, a...
The therapeutic activity, post-treatment fertility and safety of prostaglandin F2alpha-Tham salt in clinically anoestrous mares: a review. Of 275 mares receiving prostaglandin F2alpha-Tham salt for its luteolytic effect upon the corpus luteum, 231 (84 per cent) exhibited signs of oestrus (range 73-95 per cent). Some mares not exhibiting overt oestrus may, nevertheless, ovulate and post-treatment rectal palpation of mares apparently failing to respond is suggested in these cases. Of 210 mares for which subsequent history was available. 104 (49.5 per cent) became pregnant from breeding at the post-treatment oestrus that immediately followed the induced regression of the corpus luteum (range 42.2-55.5 per cent). Fertility is compara...
Horse-liver alcohol dehydrogenase and Pseudomonas testosteroni 3(17)beta-hydroxysteroid dehydrogenase transfer epimeric hydrogens from NADH to 17beta-hydroxy-5alpha-androstan-3-one. An exception to one of the Alworth-Bentley rules. In the reduction of 17beta-hydroxy-5alpha-androstan-3-one to the 3beta-alcohol, horse liver alcohol dehydrogenase utilizes the 4-pro-R hydrogen of NADH whereas the 3(17)beta-hydroxysteroid dehydrogenase of Pseudomonas testosteroni utulized the 4-pro-S hydrogen. These observations provide an exception to the rule proposed by Alworth and Bentley that with regard to the paired methylene hydrogens at C-4 of NADH and NADPH "the stereospecificity of a particular reaction is fixed and does not vary with the source of the enzyme preparation". It is also apparent that for these two enzymes, the selecti...
Cytology of diffuse mesothelioma in the thorax of a horse. Examination of effusions from body cavities must include a search for neoplastic as well as inflammatory cells. Neoplastic cells found in the thorax are generally derived from adenocarcinomas or mesotheliomas. Mesotheliomas are relatively uncommon and the neoplastic cells found in effusions are difficult to differentiate from activated cells in inflammatory effusions. An ante-mortem diagnosis of mesothelioma was made in a mare on the basis of the large volume of fluid produced, the pleomorphic mesothelial cells, the polyp formation and the absence of PAS staining material after digestion of th...
A case of peritoneal mesothelioma in a thoroughbred mare. The report describes a case of abdominal neoplasia in a mare diagnosed ante-mortem by the technique of paracentesis abdominis. Histopathological findings suggest that the lesion was a mesothelioma, primarily involving the greater omentum.
Salmonellosis in Equidae: a study of 23 cases. Salmonellosis in Equidae is a serious global problem. The prevalence may range from 0.36% to 27%. Probably 5% to 10% of the equine population in the U.S. is or has been infected. Over 40 serotypes of Salmonella have been cultured from Equidae. S. typhimurium (66.31%), S. enteritidis (9.6%), S. newport (5.16%) and S. heidelberg (4.89%) have been the most common equine isolates. The clinical and bacteriological studies of 23 naturally occurring infections in a large veterinary hospital were studied. Nine patients were infected with S. typhimurium, 8 with S. anatum, 1 with S. newport, 4 with dual...
Therapy of a horse with diarrhoea of unknown aetiology. A 5 year old Thoroughbred stallion with diarrhoea of unknown aetiology was referred to Davis. Treatment was aimed at terminating diarrhoea and restoring normal fluid status. Laboratory aids were utilised to establish where inbalance and deficits were present. Antibiotics and corticosteroids were used as an adjunct to fluid therapy. The case history and rationale of treatment of fluid disorders resulting from diarrhoea are discussed.
Characterization of protein phosphokinase activities in horse thyroid nuclei. The distribution of protein phosphokinase (EC 2.7.1.37) activities has been established in horse thyroid nuclei. The presence of several enzyme activities has been demonstrated, two of which are clearly distinct. The first one acts on histone as substrate and is activated by cyclic AMP. Physico-chemical properties of this nuclear cyclic AMP-dependent histone kinase and of the cytosol histone kinase are different, demonstrating the absence of a contamination from the cytosol. The second enzyme acts on casein as substrate and is not stimulated by cyclic AMP POR CYCLIC GMP. The findings are consi...
