Mitochondrial DNA (mtDNA) D-loop sequences (381 bp) from 100 thoroughbreds in 19 of the most common matrilineal female families were used to reconstruct a founder female population for the thoroughbred ( approximately 1650-1750 AD). Seventeen haplotypes were found to have contributed to the 19 female lineages. In order to place the reconstructed founder population in wider historical context, w...

To investigate the breeding structure in the Japanese Thoroughbred population, we applied a demographic analysis to the populations of foals produced from 1978 to 2005. The migration rate estimated from the proportion of foals produced by imported breeding horses was around 40% over the investigated period. After early 1990s, the migration rate through stallions imported from USA sharply increa...

BACKGROUND There is no comprehensive study of the costs of horse-related workplace injuries to Australian Thoroughbred racing jockeys. OBJECTIVES To analyse the characteristics of insurance payments and horse-related workplace injuries to Australian jockeys during Thoroughbred racing or training. METHODS Insurance payments to Australian jockeys and apprentice jockeys as a result of claims f...

Sternothyroideus myotomy, staphylectomy, and soft palate thermoplasty are effective treatments for Thoroughbred racehorses suffering from the performance-limiting effects of dorsal displacement of the soft palate and offer similar performance outcomes as other surgical procedures.

Over the last 15 to 20 years or so horse racing has seen declines in wagering and fan attendance throughout US. Because of this, number races, horses per race, thoroughbred farms, new thoroughbreds bred born each year for about 10 12 have also declined. The decline occurred despite simulcasting online betting, gambling machines which employ films past races (historical machines). Those racetrac...

H endra virus was first described in 1994 in Australia after a sudden outbreak of an acute respiratory syndrome in Thoroughbred horses in a Brisbane racing stable. The syndrome was characterised by severe respiratory signs and high mortality. A previously undescribed virus of the family Paramyxoviridae , initially named equine morbillivirus, was identified as the causal agent. 1 The virus was l...
