We characterized the SNP 53 JPN System for parentage verification during horse registry. The SNP 53 JPN System was constructed using 53 highly polymorphic single nucleotide polymorphisms (SNPs), which were amplified and genotyped with 2 multiplex assays. The SNP 53 JPN System showed good resolution for 95 unrelated thoroughbreds, and the exclusion probability (PE01) for each SNP ranged from 11....

this study aimed to investigate the relationship between race horse breed and the frequency of limb injuries through the time of training and racing. the study population consisted of 4042 thoroughbred and 2553 arabian horses raced at warsaw race track, from 2000 to 2008. among these horses, 94 thoroughbreds and 32 arabians had different limb injuries. based on the achieved results, it is possi...

The effectiveness of commonly used parasiticides decreases due to the drug resistance developed by many organisms. Therefore, application feed additives possessing antiparasitic properties may be helpful in limiting burden parasites. aim this research was evaluate parasitological coefficients for endoparasites regularly dewormed Arabian horses and Thoroughbreds, fed on a basal diet oat muesli w...

BACKGROUND The prevalence of equine herpesvirus types-1 and -4 (EHV-1 and -4) in South African Thoroughbreds at auction sales is currently undefined. Commingling of young Thoroughbreds from various populations together with physiological stress related to their transport and confinement at a sales complex, may be associated with shedding and transmission of EHV-1 and -4. This prospective cohort...

The aim of this paper is to identify risk factors associated with equine fractures in flat horse racing of Thoroughbreds in North America. Equine fractures were defined as any fracture sustained by a horse during a race. This was a cohort study that made use of all starts from the racecourses reporting injuries. The analysis was based on 2,201,152 racing starts that represent 91% of all officia...

Superior check desmotomy and annular desmotomy, alone or in combination, are valuable adjunct procedures in the management of superficial digital flexor tendinitis in the horse. Results of surgical management in Standardbreds are superior to those reported of conservative management and to those achieved in Thoroughbreds.

BACKGROUND Osteochondrosis is considered multifactorial in origin, with factors such as nutrition, conformation, body size, trauma and genetics thought to contribute to its pathogenesis. Few studies have investigated the effects of genetic variability of osteochondrosis in Thoroughbreds. OBJECTIVES To describe the prevalence and genetic variability of a subset of osteochondrosis lesions in a ...

Athlete’s heart is a term adapted from human medicine. It describes cardiac changes induced by prolonged and intensive training in the equine athlete. The size of the heart can be measured by echocardiography, and research has shown that size of the left ventricle is significantly correlated with athletic performance in both Standardbreds and Thoroughbreds.
