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.
Pregnancy influences the hematological profile of Carthusian broodmares. In order to investigate the effect of pregnancy on equine hematological profile, venous blood samples were taken from 44 Carthusian broodmares every two weeks during pregnancy, divided into three periods: I (conception to 110 days), II (111-220 days) and III (222 days to delivery). Routine hematological analysis was performed. Packed cell volume (PCV) increased in period II probably as a consequence of the climatic conditions or as a result of physical stress of lactation during period I. After that, a reduction in PCV was found but this was not matched with a similar decrease in total serum p...

Prevalence of gastrointestinal parasites in working horses. Fecal samples for detection of gastrointestinal parasites were collected from 221 working horses from September 2002 to May 2003 from 14 villages in Urmia, North West of Iran. Fecal samples of 46 horses (20.8%) were negative for parasite eggs or oocysts. One hundred and seventy five positive horses (48.9%) were infected with a single parasite type and 49 (22.2%) and 18 (8.1%) of horses had multiple infections with two and three parasites, respectively. The highest prevalence and intensity rate belonged to small strongyles. The overall prevalence of intestinal parasites eggs and oocyst in the p...
The effect of isotonic multiple electrolyte infusions during anesthesia on blood gas and enzymatic values in horses. General equine anesthesia is accompanied by the risk of complications and even death. The majority of general anesthetics used in veterinary practice lead to arterial hypotension, decreased capillary perfusion and ventilatory depression leading to pathological changes referred to as postanesthetic myopathy. In this study an attempt was made to analyze changes in the perioperative and postoperative acid-base equilibrium and blood enzymatic activity in horses, subject to the intensity of the applied fluid therapy. The horses were divided into two groups: I--administered Ringer's solution during ...
Comparison of hematologic and biochemical results on blood obtained by jugular venipuncture as compared with intravenous catheter in adult horses. During hospitalization, horses typically undergo frequent blood sampling for diagnostic testing and monitoring. The need for numerous samples in hospitalized horses makes acquisition from an intravenous catheter (IVC) both convenient and less stressful to the patient. Objective: We hypothesized that there would be no significant difference in the plasma chemistry and CBC variables from blood samples obtained from a jugular catheter as compared with direct jugular venipuncture. Methods: Fifty adult hospitalized horses; 25 receiving constant rate crystalloid therapy, and 25 receiving low volume ...

Orthopaedic health status of horses from 8 riding schools–a pilot study. Orthopaedic injury is the most common reason for lameness and wastage in sport and leisure horses. Studies on racehorses have shown differences in injury risk between trainers and training strategies. The aim was to study between riding school variation in orthopaedic health status by clinical examination and horses age, and control for change of examiner, in schools with previous high (n = 4) and low (n = 4) insurance utilisation. Methods: Horses (n = 99) at 8 riding schools were examined for conformation, movement in all gaits, standing flexion tests and palpation by two veterinary surgeons ...
Cytogenetic and genetic studies in a hypospadic horse (Equus caballus, 2n = 64). A 4-year-old male horse of Friesian breed with normal body conformation, development and libido, and showing an evident ventral penis deviation with hypospadias, underwent both cytogenetic and genetic investigation. Although the karyotype showed normal male arrangement (2n = 64,XY), one telomere of horse (ECA) chromosome 1 was shorter than both the other one and those of a normal horse (control), as revealed by CBA- and RBA-banding, and by Ag-NOR and FISH-mapping techniques using telomere PNA probes. Genetic investigation of the SRY and MAMLD1 coding sequences revealed a normal SRY sequence an...

Information obtained included medical (included horses subjected to euthanasia without s...
Distances between thoracic spinous processes in Warmblood foals: a radiographic study. The aetiological factors behind impinged or overriding of dorsal spinous processes ('kissing spine syndrome', KSS) are not clearly understood. Back conformation, breed, age, training and gender may play important roles in this condition. Radiographic changes vary and abnormalities are seen in many clinically normal horses, but the conclusion of previous studies in mature horses is that interspinous spaces <4 mm are considered too narrow and potentially indicative of KSS. Objective: To evaluate whether narrowing of the interspinous space was present in a population of normal Warmblood foals....
Quantitative evaluation of subchondral bone injury of the plantaro-lateral condyles of the third metatarsal bone in Thoroughbred horses identified using nuclear scintigraphy: 48 cases. Increased radio-isotope uptake (IRU) in the subchondral bone of the plantaro-lateral condyle of the third metatarsus (MTIII) is a commonly reported scintigraphic finding and potential cause of lameness in UK Thoroughbred racehorses in training and has not been fully documented. Objective: To characterise lameness attributable to IRU of the subchondral bone of MTIII, compare the scintigraphic findings of these horses with a normal population and evaluate the use of scintigraphy as an indicator of prognosis.
