The calcium and phosphorus nutrition of thoroughbred racehorses was assessed by analysis of serum and urine samples collected from 90 horses in 1975 and 139 horses in 1980-81 at racetracks in Melbourne. Horses that were excreting greater than 15 mumole Ca/mosmole and which had a calcium to creatinine clearance ratio greater tha 2.5% were considered to have adequate Ca intake. Horses that were e...

Although estimates of heritability of performance in the Thoroughbred racehorse have been calculated to be between 10-40%, no genes influencing performance have been identified. Based on comparative studies with human, we identified the angiotensin-converting enzyme (ACE) gene as an equine candidate gene for performance. From characterization of nine SNPs, nine equine ACE haplotypes were identi...

in this study, in vitro growth characteristics of fibroblasts of metacarpal region of horses and caspian miniature horses were evaluated. under general anesthesia and aseptic condition, a full thickness skin incision was created on the lateral aspect of mid-third of left metacarpal region of 4 mixed thoroughbred horses and 4 caspian miniature horses and 3 grams of subcutaneous tissue was harves...

Aortic rupture is a well recognized cause of sudden death in thoroughbred horses. Some microscopic lesions, such as those caused by cystic medial necrosis and medionecrosis, can lead to aortic rupture. However, these microscopic lesions are also observed in normal horses. On the other hand, a previous study of aortic rupture suggested that underlying elastin and collagen deposition disorders mi...

This article presents the results of an electrocardiographic study English thoroughbred racehorses with cardiac pathologies. Diagnosis was performed on 4-, 5-, and 6-year-old horses before after exercise. It noted that tachycardia various abnormalities were observed in many animals. Currently, there is increase number pathologies related to cardiovascular system diagnosed sport horses, which ca...

The aim of this study was to determine serum and synovial concentrations of the CS-846 epitope of articular cartilage aggrecan, in horses with a radiological diagnosis of osteochondral fragmentation (OF). For this purpose, 20 thoroughbred horses with unilateral radiocarpal or intercarpal OF were used, and 10 clinically and radiologically healthy Thoroughbred horses were assigned to the control ...

Exercise-induced pulmonary hemorrhage (EIPH) is ubiquitous among Thoroughbred racehorses throughout the world, and there is no apparent important geographic variation in incidence of the condition. Although EIPH is very common, the exact incidence of the condition varies depending on the method of diagnosis and the frequency of examination. Examination of bronchoalveolar lavage fluid (BAL) or t...

OBJECTIVE To estimate prevalences of various presale radiographic findings and of presale arthroscopy in horses offered for sale at the 2006 Keeneland September yearling sale and to compare sales prices between yearlings with and without various presale radiographic findings or a history of arthroscopy. ANIMALS 397 Thoroughbred yearlings. DESIGN Cross-sectional study. PROCEDURES Presale r...

Getah virus (GETV), which is transmitted by mosquitoes, causes lower limb edema and stiffness in horses. In this study, we investigated the sero-surveillance of GETV among Thoroughbred racehorses in Korea during 2013 and 2014. A total of 1,182 equine serum samples collected from Thoroughbred racehorses in four provinces (Gyeongnam, Gyeonggi, Jeonbuk and Jeju provinces) were analyzed using virus...

Copy number variations (CNVs), important genetic factors for study of human diseases, may have as large of an effect on phenotype as do single nucleotide polymorphisms. Indeed, it is widely accepted that CNVs are associated with differential disease susceptibility. However, the relationships between CNVs and gene expression have not been characterized in the horse. In this study, we investigate...
