No adverse effects in racing TBs as two-year-olds – study
An Australian written report of 117,088 thoroughbreds establish that those raced regularly every bit two-years-olds were to a greater extent than probable to accept longer careers.
Researchers from the Faculty of Veterinary Science at the University of Sydney in addition to the Sydney Medical School said overseas thoroughbred studies had provided prove of a positive lawsuit on racing careers for horses that started racing every bit two-year-olds, merely enquiry inwards the surface area was express inwards Australia.
They laid upwardly out to investigate the association betwixt the historic current at kickoff start in addition to career length, in addition to to gauge the run a endangerment of racing retirement for horses racing inwards Commonwealth of Australia based on historic current at kickoff start, career earnings, the issue of starts every bit a two-year-old, in addition to distance raced.
The researchers, whose findings accept been published inwards the Equine Veterinary Journal, establish no prove of adverse effects inwards starting thoroughbreds at two-year-olds.
The researchers collected information for Australian thoroughbreds born on or subsequently Jan 1, 1998, that had raced betwixt August 1, 2000, in addition to Feb 22, 2011.

The run a endangerment of retirement from racing decreased alongside a younger historic current at kickoff start, a higher issue of starts every bit a two-year-old, in addition to a longer average distance raced.
For stallions, the run a endangerment of retirement from racing increased every bit lucre increased, piece for mares in addition to geldings the run a endangerment of retirement from racing decreased every bit lucre increased.
“The introduction of immature thoroughbreds to racing appears to accept no apparent adverse effects on these horses racing inwards Australia,” the authors concluded.
“The acquit on of about run a endangerment factors associated alongside retirement from racing varied betwixt sexes in addition to should survive considered when evaluating career outcomes,” they noted.
