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 complete amino acid sequence of horse muscle acylphosphatase. The amino acid sequence of horse muscle acylphosphatase is given in the present paper. The carboxymethylated enzyme consists of a single polypeptide chain of 98 amino acid residues with an acetyl group blocking the NH2 terminus and a tyrosine at the COOH terminus. The calculated molecular weight of the native protein, a mixed disulfide with glutathione, is 11,365. The carboxymethylated protein was cleaved by cyanogen bromide. The three expected fragments were purified; moreover, an additional fragment, derived from a partial failure of cleavage at methionine-24, was purified and characterized....
Limitations in equine fetal electrocardiography. Technical and interpretive limitations of equine fetal electrocardiography were evaluated in recordings obtained from 45 pregnant mares. Technical limitations were related to the small amplitude of the fetal electrocardiogram and the variability in the lead configuration providing the best recording. It was found that recording the fetal electrocardiogram at high sensitivity and high base-line fidelity in several different leads was necessary to obtain satisfactory tracings. Interpretive limitations were related in part to the small amplitude of the fetal electrocardiogram and to the marked va...
[Use of trichlorfon as an anthelmintic in horses (author’s transl)]. The use of trichlorfon as an anthelmintic in horses has increased since it was combined with mebendazole and febantel, and became commercially available as Telmin-trichlorfon and Rintal-plus respectively. Field studies showed that these combined preparations frequently gave rise to cases of poisoning. Mild to severe colic was observed up to six hours after treatment, diarrhoea and/or anorexia continuing to be present for one to six days after administration. The 'horse weight measurer' introduced by Janssen Pharmaceutica is not sufficiently accurate to prevent overdosage. It is advisable only ...
Assembly of intra- and interspecies hybrid apoferritins. An intraspecies hybrid apoferritin was assembled by mixing subunits of horse heart ferritin, which consists mainly of H-type subunits, and horse spleen ferritin, in which L-type subunits predominate. Interspecies hybrid apoferritins were reconstituted from subunits of human liver-horse spleen ferritins and from rat liver-horse spleen ferritins. All the hybrid ferritins migrated as single zones with electrophoretic mobilities intermediate between those of the parent ferritins. Isoelectric focusing data and immunological patterns were consistent with the view that the reassembled apoferritins we...
The management of rectal tears in horses. Rectal trauma in horses is usually iatrogenic and carries a high mortality. Partial thickness tears heal without surgical assistance. Full thickness tears require surgical repair through the anus or a ventral laparotomy or, if these are not possible because of difficulty in gaining access to the tear in its usual site at the pelvic inlet, a diverting colostomy to allow the rectum to heal is necessary. This paper describes the management of 15 cases of rectal injury, only 3 of which survived. Two of these were partial thickness tears not treated surgically and the third had a temporary divertin...
Principles of drug administration in the horse. This paper is an introduction to a series of commissioned articles on therapeutic medicine to be published in Equine Veterinary Journal under differing authorship, during the next 2 years. It presents an account of fundamental concepts common to the use of all drugs and introduces some pharmacokinetic principles to which reference will be made in later articles.
Transplacental transmission of Venezuelan equine encephalitis virus in horses. Transplacental passage of Venezuelan equine encephalitis virus, epizootic strain P-676, occurred in four of nine fetuses studied. The mares were infected near term. Virus was recovered in high titer from fetal blood and organs, while no virus was detected in maternal blood but neutralizing antibodies were present. No evidence of in utero infection was found in two fetuses from mares infected with MF-8, another epizootic strain of Venezuelan equine encephalitis virus.
[The effect of the age of stallions and mares on their fertility]. The study was based on the documentation of the Napajedla Stud Farm of the English Thoroughbred horse for 1888-1972. Evaluating the effect of the age of stallions on their fertility (leaving aside the variability of the age of their mothers), such an effect was found to be significant only in four out of the 26 studs evaluated. In 65% of the selected stallions, the correlation coefficients were found to be negative, but without statistical significance. However, the objective of the study was to evaluate stallions and mares parallelly as to their age variability and fertility. The relationship...
Cytologic interpretation of peritoneal fluid in the evaluation of equine abdominal crises. Cytologic examination of serial peritoneal fluid samples of nine experimental ponies was performed during a 72 hour period following laparotomy. Six of the ponies had jejunal infarction induced by occlusion of the corresponding vasculature. Cytologic examination was also performed on the peritoneal fluid of a series of horses with naturally occurring abdominal crises presented to the Large Animal Clinic. A rapid staining technique allowed evaluation of smears within 5 minutes of obtaining the fluid. Alterations in peritoneal fluid of the experimental and clinical cases reflected an acute infla...
Subepiglottic cyst in three foals. Three foals with chronic cough, bilateral nasal discharge, and pneumonia were found to have a subepiglottic cyst as the inciting cause. Consistent findings were dysphagia and aspiration pneumonia, in addition to the abnormal respiratory noise usually found in the adult horse with a subepiglottic cyst. Histologic examination of the cysts suggested their origin was traumatic rather than embryonic.
[Onions: not a horse feed (author’s transl)]. Two horses became ill, and one died, after being fed onions, presumably over a long period. Their intake of grass was low at the time of illness because the pasture was covered with snow. Examination of blood and urine revealed signs of severe haemolytic anaemia.
The reaction of imported British Shire horses to African Horse Sickness: A case report. Summary Twelve (12) heavy horses of the Shire breed imported into Nigeria in 1974 died within two months after importation. This was because of inclement weather and non-availability of AHS vaccine.
The slap test for laryngeal adductory function in horses with suspected cervical spinal cord damage. The paper describes the assessment and practical implications of a laryngeal adductory reflex in a series of 30 ataxic and 64 non-ataxic horses. The reflex was evoked by slapping the saddle region just caudal to the withers. In normal horses this produced a flickering adductory movement of the contralateral arytenoid cartilage which was observed endoscopically. Abolition of the laryngeal response was encountered in in 3 situations:--(1) Disruption of the afferent impulse occurred in those horses in which there was significant spinal cord pathology affecting the pathway from the cranial thoraci...
