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.
Effects of castration on peritoneal fluid in the horse. Twenty-four clinically normal horses were castrated by routine methods. Peritoneal fluid was collected prior to castration and at 1, 3, 5, and 7 days postcastration. Peritoneal fluid was collected on days 9 and 11 if nucleated cell (NC) counts were still markedly elevated on day 7. Peritonitis, defined as NC counts greater than 10,000/microliters, was evident in 15 horses following castration. Mean NC counts peaked on day 5 but were less than 10,000/microliters for 74% of the horses by day 7, and 90% of the horses by day 9. One horse had a NC count greater than 60,000/microliters on day 11 whe...
A monoclonal antibody identifying a T-cell marker in the horse. A cell surface molecule of equine T lymphocytes was identified and characterized using a mouse monoclonal antibody, HT23A. The molecule was detected on all T cells but not on other cells in peripheral blood, with the possible exception of a small subpopulation (about 5%) of B cells, as assessed by indirect immunofluorescence and flow cytometry. HT23A labelled T cell areas of horse lymph nodes and spleen when used in an indirect immunoperoxidase assay on frozen sections. Macrophages and neutrophils were not labelled by the antibody nor were frozen sections of horse liver, kidney, or brain. HT23...
[Spinal lymphosarcoma in a foal]. The present report describes the clinical and pathological findings of a one year old foal presented with paralysis of the hind legs. Macroscopically and histologically, a lymphosarcoma in the vertebral body and the adjacent epidural space of T 16, in the spleen and the mesenterial lymph nodes was observed. The adjacent spinal cord showed focal degenerative changes characterized by dilatation of myelin sheaths, swollen axons and few macrophages.
Propagation and quantitation of animal herpesviruses in eight cell culture systems. A comparative study was carried out to determine the relative sensitivities of eight different cell culture systems to six different herpesviruses of animals. The cells used were: OFL (ovine fetal lung), ML (mink lung), FK (ferret kidney), PTK-2 (potoroo kidney), TEK (turkey embryo kidney), ED (equine dermal), BT (bovine turbinate), and PK15 (porcine kidney). The viruses tested were: PRV (pseudorabies) of swine, CPHV (caprine herpesvirus), IBRV (infectious bovine rhinotracheitis virus), DN-599 strain of bovine herpesvirus type 4, EHV-1 (equine herpesvirus), and CHV (canine herpesvirus). On the...
The use of urea as a marker of body water in the nursing foal. Urea, compared with deuterium oxide (D2O) as a reference, was used as a body marker to estimate body water volume in ten 2-month old nursing foals. Plasma urea clearance was regular over 10 h and the R2 of the disappearance curve was between 0.93 and 0.98. Mean urea space was about 4% lower than D2O space, but the standard deviation of the proportion of water in body weight was higher with urea (3.8%) than with D2O (1.6%). Calculated urea entry rate was 49 mg/h/kg LW0.75.
Osseous sequestration in the horse. A review of 68 cases. Sixty-eight cases of cortical bone sequestration in 67 equine patients were reviewed with regard to the clinical presentation, method of treatment, and outcome. All lesions were located in skeletal areas with minimal soft tissue coverage, with 53% of them in the metatarsal and metacarpal bones. At the time of admission, 60% of the patients with limb lesions were lame; the majority improved with therapy. After sequestrectomy, there was a trend for surgical wounds which could be managed by primary closure to heal more rapidly (3.8 weeks) than wounds which required second intention healing (6.4 w...
[The diagnosis of morbus maculosus in horses]. This is a review on Morbus maculosus equorum (purpura haemorrhagica) on the base of literature data and of a case report on 13 own patients. It is shown, that the clinical picture of this disease has not changed within the last 150 years. Clinical main symptoms are haemorrhagic diathesis (petechiae, ecchymosis, suggillations) as well as peripheral edema and fever. The main haematological findings are neutrophilia, mostly going along with shift to the left and lymphopenia. In the last few years thrombocytopenia was also described in some cases. Basic therapeutics are glucocorticoids and penicil...
[Changes in several blood and urine parameters during combined hyperfluid therapy for the treatment of chronic obstructive bronchitis (COB) in the horse]. During the combination of oral and intravenous application of saline solution for treatment of the COPD of horses the level of hydraemia basing on the total protein concentration in the serum, the urine production and the specific weight of urine was determined. Additionally the development of serum concentration and of renal excretion rates of potassium, calcium and magnesium were ascertained. The level of hydraemia resulting from the combined method is almost identical with the solely intravenous performed hyperinfusion therapy. Due to the excessive application of fluid an extremely high lev...
Bypass surgery for the treatment of small intestinal ileus in the horse. A report of three cases. The medical management of three horses with simple and strangulating small intestinal obstructions was unsuccessful and was therefore supported by surgical bypasses. Jejunocecostomies were used to treat horses with postoperative paralytic ileus that was unresponsive to medical management. These horses had abdominal pain, gastric distention, heart rate elevations greater than 60/minute, and small intestinal distention on rectal palpation. Two horses experienced weight loss which responded to bypass removal. The bypass effectively decreased the need for intravenous fluid administration and repea...
Equine disease association studies: a clinician’s perspective. Diagnostic criteria should be carefully defined and described in disease association studies to allow (1) comparison among studies from different laboratories evaluating the same disease, (2) critical evaluation of selection procedures of patients, and (3) to strengthen genuine associations with any genetic marker system. Factors to consider include age at onset of disease, specialized diagnostic methods necessary to diagnose or eliminate patients with a selected disease, ranges of affectedness and differences in sex expression.
The use of H(orse) INDEX: a method of analysing the ground reaction force patterns of lame and normal gaited horses at the walk. The amplitudes, impulses and times of occurrence of a number of selected peaks in the ground reaction force tracings of 17 horses with various clinical histories were compared with those of 20 horses used to establish values for the 'standard' Dutch Warmblood horse. The resulting factors were combined, using different weighting factors, into indices characterising each limb. The symmetry between the loading of the forelimbs and the hindlimbs was used to calculate amplitude and peak-time symmetry indices. Limb and symmetry indices were combined in one H(orse) INDEX. This method of quantifying t...
Development of a scoring system for the early diagnosis of equine neonatal sepsis. A sepsis scoring system was developed and tested prospectively in a blind study of 190 neonatal foals admitted to the University of Florida Veterinary Medical Teaching Hospital's neonatal intensive care unit. The system used 14 readily available historical, clinical or laboratory variables and weighted each item to arrive at a sepsis score. The score was found to have a sensitivity of 93 per cent, a specificity of 86 per cent, positive accuracy rate of 89 per cent and negative accuracy rate of 92 per cent. The sepsis score was far more sensitive and specific for infection, even in very early c...
Exploratory celiotomy for suspected urinary tract disruption in neonatal foals: a review of 18 cases. The medical records of 18 neonatal foals, in which exploratory celiotomies were performed for suspected urinary tract lesions, were reviewed. Despite clinical signs and laboratory values indicative of disruption of the urinary tract, three foals did not have a site of urinary tract leakage at surgery. Eight foals had ruptured bladders and seven foals had urachal lesions. Ultrasonography was used as a pre-operative diagnostic procedure in eight foals to evaluate the presence of free peritoneal fluid and urinary tract integrity. Nine foals were alive six months after discharge. Seven of the nine...
[The problems of mastitis in mares]. Based on a group of 33 mares infected with mastitis, data regarding the time of appearance, the clinical symptoms and the bacteriological causes of the disease were evaluated. The cases were distributed as follows: 27.3% before delivery, 24.2% immediately after delivery (until the third day), 12.1% during the middle and late stages of lactation, 9.1% immediately after the weaning of the foal and 27.3% outside the lactation period of non-pregnant mares. The clinical picture is described. In the majority of the cases, both halves of the udder were infected. The analysis of the bacteriological re...
Platelet activating factor as a mediator of equine cell locomotion. Equine polymorphonuclear (PMN) and mononuclear (MN) leucocytes were separated on Percoll gradients and used to study the chemoattractant properties of the polar ether-linked phospholipid, platelet activating factor (PAF). Six concentrations of PAF ranging from 1 ng/ml to 100 micrograms/ml were studied in each of two in vitro assay systems, the agarose microdroplet and a microfilter technique. Very significant (p less than 0.01) increases in the movement of both PMN and MN cells were obtained with most concentrations of PAF. In two instances there was no apparent concentration-response relation...
Exploratory celiotomy for gastrointestinal disease in neonatal foals: a review of 20 cases. The medical records of 20 neonatal foals in which exploratory celiotomies were performed for gastrointestinal disease were reviewed. In all 20 foals, persistent pain and/or progressive abdominal distension were the primary clinical findings influencing the decision to operate. However, ancilliary laboratory data were important to the proper medical management of these foals during anaesthesia and following surgery. Surgical diagnoses of the 20 foals included ileus (nine foals; 45 per cent), small colon obstruction (five foals; 25 per cent), large colon displacement (three foals; 15 per cent), ...
