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.
Pure preovulatory follicular fluid promotes in vitro maturation of in vivo aspirated equine oocytes. In the mare, rates of fertilization and development are low in oocytes matured in vitro, and a closer imitation of in vivo conditions during oocyte maturation might be beneficial. The aims of the present study were, therefore, to investigate whether (1) equine oocytes can be matured in vitro in pure equine preovulatory follicular fluid, (2) priming of the follicular fluid donor with crude equine gonadotrophins (CEG) before aspiration of preovulatory follicular fluid promotes the in vitro maturation rate, (3) the in vitro maturation rate differs between oocytes aspirated during estrus and those...
Paecilomycosis in dogs and horses and a review of the literature. We reviewed 14 cases of paecilomycosis in a tertiary care veterinary hospital and all reports of the disease in the veterinary literature. Paecilomycosis is a rare disease primarily of dogs, horses, reptiles, and humans. Clinical manifestations in veterinary patients vary but include disseminated disease and diskospondylitis, particularly in dogs: pneumonia in dogs, horses, and reptiles; keratitis in horses; and miscellaneous local infections. It is important to have an appropriate index of suspicion because the diagnosis can be difficult, particularly in localized disease where it is difficul...
Artifactual changes in equine blood following storage, detected using the Advia 120 hematology analyzer. Delayed analysis of blood samples may be caused by restricted access to laboratories. Artifactual changes may occur in the measured analytes as a consequence of delayed analysis and may complicate interpretation of the data. Objective: The purpose of this study was to characterize artifactual changes in equine blood, due to storage, using the Advia 120 hematology analyzer. Methods: Samples of blood from 5 horses were analyzed using the Advia 120 soon after collection and again after 24 and 48 hours of storage at either 4 degrees C or ambient laboratory temperature ( approximately 24 degrees C)...
Biochemical and antioxidant changes in plasma and erythrocytes of pentathlon horses before and after exercise. Physical exercise in the horse induces a series of normal physiological and biochemical adaptations. Increasing metabolism and oxygen uptake may induce oxidative stress in various organs. The aim of this study was to examine exercise-induced changes in some plasma and RBC biochemical and antioxidant variables in pentathlon horses. Blood samples were taken from 14 horses before, immediately after, and 24 hours after competing in two 1-minute runs of intense exercise over jumps. The peak intensity periods were preceded by a 20-minute warm-up and separated by a 20-minute break. The following plas...
Of patients & horses. Equine-facilitated psychotherapy. 1. Horses, just by their large, gentle presence, put people therapeutically in touch with the vitality of being alive. 2. People who ordinarily shun physical and emotional closeness often can accept closeness from a horse and through therapy can transfer these skills to their daily lives. 3. The behavior of a sensitive horse display the rider's emotions to the therapist and provides a vehicle the therapist can use to teach the patient coping skills. 4. Therapists with an interest in horses can learn more about how to become involved in an equine-facilitated psychotherapy practice through the N...

Methods: Signalment; history; clinical signs; clinicopathologic, echocardiographic, and radiographic findings; treatment; and outcome were determined by reviewing medical records. Results: All 14 horses were examined because of a heart murmur; tachycardia was identified in all 14. Twelve horses had echocardiographic evidence of enlargement of 1 or more chambers of the heart. Other common clinical finding...
Myoglobin-CO conformational substate dynamics: 2D vibrational echoes and MD simulations. Two-dimensional (2D) infrared vibrational echoes were performed on horse heart carbonmonoxymyoglobin (MbCO) in water over a range of temperatures. The A(1) and A(3) conformational substates of MbCO are found to have different dephasing rates with different temperature dependences. A frequency-frequency correlation function derived from molecular dynamics simulations on MbCO at 298 K is used to calculate the vibrational echo decay. The calculated decay shows substantial agreement with the experimentally measured decays. The 2D vibrational echo probes protein dynamics and provides an observable ...
Ankle-foot orthoses: effect on gait in children with cerebral palsy. In this study our aim was to evaluate the effectiveness of Ankle-Foot Orthoses (AFOs) on gait function in patients with spastic cerebral palsy for whom orthoses were indicated to control dynamic equines deformity. Methods: Twenty-four spastic cerebral palsied patients with dynamic equines deformity were included in the study. Videotape recordings were performed to each patient on the same day with barefoot and AFOs. Temporal distance factors including velocity, cadence, stride length, stride width and Clinical Gait Assessment Score (CGAS) were compared across two conditions. Results: The use o...
Separation and characterization of mares’ milk alpha(s1)-, beta-, kappa-caseins, gamma-casein-like, and proteose peptone component 5-like peptides. The equine alpha(s1)- and beta-caseins (CN) were purified by chromatography on DEAE-cellulose and by reversed-phase HPLC. The alpha(s1)-, beta-, and kappa-CN were characterized either by monodimensional urea-PAGE or sodium dodecylsulfate (SDS)-PAGE or by bidimensional electrophoresis. Kappa-casein was characterized after electrophoresis by glycoprotein-specific staining. To identify alpha(s1)-CN without ambiguity, internal sequences were determined after trypsin or chymosin digestion of purified alpha(s1)-CN. These sequences, that could be estimated to correspond to 62% of the full protein, pr...

To determine the predictive values, sensitivity and specificity of abdominal fluid variables associated with the need for surgery in horses with an acute abdominal crisis. Methods: Retrospective study. Methods: Two-hundred and thirty-six horses examined for signs of abdominal pain between January 1993 and June 1999. Methods: Breed, age and gender of the horse and colour, total protein concentration and total nucleated cell count of an abdominal fluid sample were recorded. Colour of the abdominal fluid was classified as normal if it was yellow and transparent. Turbid fluid or fluid that was ser...
Non-surgical management of rectal tears in two mares. Two mares presented with life-threatening rectal tears were successfully treated with intensive medical management. Although surgery has been regarded as mandatory for grade 3 or 4 rectal tears in the past, recent reports have indicated the value of medical management alone. The case reports presented in this article detail the use of antibiotics, flunixin meglumine, laxative diets and faecal softeners in the medical management of two mares presented with grade 3 rectal tears.
Osteoma of paranasal sinuses in a horse with inspiratory dyspnoea. We describe a case of osteoma in the frontal and maxillary sinuses of a 3-year-old Arabian mare, presented due to an inspiratory dyspnoea. The mare underwent two surgical procedures in order to excise the tumour. Twelve months after admission the mare was healthy with no signs of respiratory abnormalities. Sinus radiographs and endoscopy repeated at that time revealed some regrowth of the tumour in the maxillary sinus, however, twenty-two months following surgery the mare did not show clinical signs of upper airway disease.
Surgical cleft soft palate repair in a foal. An Anglo-Arab foal with bilateral postprandial nasal discharge was diagnosed as having a full-length defect of the soft palate. Surgical repair was attempted using a combination of two surgical approaches. Initially a mandibular symphysiotomy approach was used. The posterior portion of the defect did not heal adequately, so a ventral laryngotomy, bisecting the body of the thyroid cartilage and extending to a pharyngotomy approach, was performed 5 months later. The foal has since matured fully despite a slight unilateral nasal discharge. This case report demonstrates that these two surgical app...
Effects of aqua-treadmill exercise on selected blood parameters and on heart-rate variability of horses. The objectives of the present study were to investigate the effects of Aquatraining of horses (aqua-treadmill exercise; treadmill manufactured by Equitech - L.u.S. Equipment, Warendorf, Germany) on selected blood parameters [lactic acid concentration (mmol/l), haemoglobin content (g/l)] and on heart-rate variability (HRV) [heart rate (beats per min; b.p.m.), standard deviation of all NN-intervals (SDNN; ms), normalized power of the low and high frequency band (LFnorm, Hfnorm; au), % recurrence, % determinism and ratio(corr)]. Seven horses performed six exercise tests with different work loads ...
Effect of time of oocyte collection and site of insemination on oocyte transfer in mares. The objective of the study was to compare embryo development rates after transfer of oocytes collected 22 or 33 h after hCG injection into recipients inseminated within the uterus or the oviduct. Oocytes were collected at approximately 22 or 33 h after hCG injections and incubated for approximately 16 or 1.5 h, respectively, before transfer. Intrauterine inseminations using 1 x 10(9) progressively motile sperm were done approximately 12 h before and 2 h after transfer. For intraoviductal inseminations (gamete intrafallopian transfer [GIFT]), semen was centrifuged through a Percoll gradient, an...
Effects of body position on intracranial and cerebral perfusion pressures in isoflurane-anesthetized horses. Inhalant anesthetics may interfere with normal cerebrovascular autoregulation. It was, therefore, hypothesized that intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in isoflurane-anesthetized horses would be especially sensitive to body and head position because of the potential for large hydrostatic gradients between the brain and heart in this species. Anesthesia was induced and maintained in six clinically healthy, unmedicated geldings with 1.57% isoflurane in O(2); mechanical ventilation was used to maintain normocapnia. ICP was measured by using a subarachnoid strain-gaug...
Ultrasonographic and histologic evaluation of medial and middle patellar ligaments in exercised horses following injection with ethanolamine oleate and 2% iodine in almond oil. To describe the ultrasonographic and quantitative histologic effect of injecting 2% iodine in almond oil (IAO) and ethanolamine oleate (EO) in the medial and middle patellar ligaments of horses and to determine whether a difference in response exists between IAO and EO treatment. Methods: 10 healthy horses. Methods: In 5 horses, the medial and middle patellar ligaments of 1 limb were injected with EO, whereas IAO was injected in the medial and middle patellar ligaments of another 5 horses. Ultrasonographic evaluation was performed on the experimental and control limb before injection of IAO an...
Metastatic lymphangiosarcoma in a horse. A lymphangiosarcoma with metastases was found in a horse that presented with respiratory distress and edema in the ventral thorax and abdomen. The necropsy revealed diffuse edema in the subcutaneous connective tissue. Mediastinal, mesenteric, iliac, and renal lymph nodes were enlarged and white with soft, yellowish necrotic areas. Histologic examination revealed numerous channels and disorganized vessels lined by large polyhedral, polymorphic cells. Tumor metastases were observed in the spleen, lungs, and kidneys. Immunohistochemical evaluation of the tumor cells demonstrated positive staining...
Hematuria and a complex congenital heart defect in a newborn foal. A 16-hour-old foal was referred for evaluation of hematuria. A pansystolic heart murmur and left thoracic thrill were detected; laboratory diagnostics and ultrasonography identified a complex congenital heart defect. The diagnosis was confirmed at postmortem.
Farm safety issues in Old Order Anabaptist communities: unique aspects and innovative intervention strategies. The Amish and other Old Order Anabaptists have been inseparably linked with agriculture since coming to America. However few efforts have been identified which analyze the issues involved with Old Order Anabaptist farm injuries or present best practices for addressing these problems. As part of an effort to develop culturally appropriate and effective injury prevention strategies for use within the Old Order Anabaptist community, this article identifies important cultural issues that should be considered in understanding and attempting to reduce farm injures in this population, summarizes stat...
Severe renal hemorrhage caused by pyelonephritis in 7 horses: clinical and ultrasonographic evaluation. Case records of 7 horses diagnosed with pyelonephritis were reviewed to determine common features that might aid in diagnosis, treatment, and prognosis of this disease. All 7 horses had been admitted for evaluation of hematuria. During cystoscopy of 5 horses, hemorrhage was observed from one or both ureters. Renal biopsy of 1 horse, laboratory analysis of ureteral discharge of 2 horses, and renal ultrasonography of all horses indicated that pyelonephritis was the cause of hemorrhage. Sonographic renal changes included decreased length, increased echogenicity, abnormal outline, loss of corticom...
Helminth control used by trainers of thoroughbreds in England. A telephone survey was conducted of the methods used to control parasitic worms at 106 thoroughbred training yards. Most of the horses were allowed access to grass and were therefore at risk of infection. The control methods relied primarily on the use of anthelmintics and appeared reasonably successful because only 44 per cent of trainers reported observing clinical signs of nematode infections. They dosed their horses frequently, 40 per cent treating every four to six weeks and 25 per cent treating every seven to eight weeks. New arrivals on yards were usually treated with anthelmintic but t...
