It is understood that each horse always runs the distance in the same time and the horses have distinct speeds. You have no stopwatch, but can make deductions from the finishing order in the races. When deciding which horses to race, information obtained from previous races may be used. These conditions apply for all problems we present here. As often happens, the problem leads to many interest...

Previous studies showed a positive effect of the DMRT3 "gait keeper" mutation on harness racing performance in Standardbreds, French-, and Nordic trotters. The mutation has also been shown to influence riding traits in multiple breeds. This study investigated the effect of the DMRT3 mutation on harness racing performance and riding traits in Finnhorses. Finnhorses used for harness racing (n = 1...

In this study, we estimated the heritability (h(2)) of earnings in the Quarter Horse in order to evaluate the inclusion of this trait in breeding programs. Records from 14,754 races of 2443 horses from 1978-2009 were provided by Sorocaba Hippodrome, São Paulo, Brazil. All ancestors of the registered horses were included in the pedigree file until the 4th generation. Log-transformed performance ...

various forms of intensive sport place stress on the musculoskeletal system of the horse, during both racing and training. the musculoskeletal system of the horse has an inherent ability to adapt to the demands of high speed exercise, but exceeding the threshold of adaptive capacity may result in some form of damage. continuing racing or training may delay the repair process and put the horse a...

Assuring a high level of animal welfare is critical aspect contemporary husbandry. Equine athletes begin their careers at very young age when they are still developing and both physically mentally immature. Lack scientific knowledge the stress related to horse racing impedes development optimal training programs attain equilibrium between best sport results welfare. This study aimed determine i...

OBJECTIVE To determine clinical and radiographic features of subchondral cystic lesions (SCL) of the proximal extremity of the tibia in horses that could be used to classify these lesions as being related to osteochondrosis or osteoarthritis and to evaluate results of surgical debridement. DESIGN Retrospective study. ANIMALS 12 horses with 14 SCL. PROCEDURE Medical records and radiographs...

OBJECTIVE To evaluate records of racehorses with palmar carpal osteochondral fragments and determine whether the fragments were indicators of the severity of pathologic joint changes or prognosis. DESIGN Retrospective case series. ANIMALS 31 racehorses. PROCEDURES Medical records, radiographs, and videos of arthroscopic procedures were reviewed. Information gathered included signalment; l...

OBJECTIVE To evaluate nonsurgical management of type II fractures of the distal phalanx in Standardbred horses. DESIGN Retrospective study of 48 affected horses. RESULTS Most fractures occurred on the lateral palmar process of the left forelimb or the medial palmar process of the right forelimb; 81% of horses were considered sound enough to return to training and 63% raced. Of those returni...

The purpose of this study was to examine the longevity of postoperative careers and quality of performance of 461 Thoroughbred racehorses after arthroscopic removal of dorsoproximal first phalanx (P1) osteochondral fractures. Six hundred and 59 dorsoproximal P1 chip fractures were removed arthroscopically from 574 joints in 461 horses presented for lameness or decreased performance attributed t...
