Research investigating trends in racehorse careers require a benchmark for accurate comparison. Currently little whole population data exists for horses racing in Australia.
To determine the range and variation in career length and number of career starts for horses racing in Australia. To document and provide evidence regarding the current differences between the sexes for career length and careers starts.
Racing data were collected for Thoroughbreds over a 10-year period. Career length, number of career starts and spells per year were evaluated. Statistical analyses were performed using the statistical package R.
A total of 2,782,774 performance records yielded career information for 164,046 horses. Median career length and number of career starts for the population were 14.7 months and 10 starts, respectively. Significant differences (P<0.001) were present between the sexes for all career outcomes. Between 2000 and 2010, the percentage of Thoroughbreds racing in Australia with careers longer than 12, 24, 36 and 48 months was 56.65, 32.35, 16.66 and 7.74, respectively.
Clear differences in career outcomes exist between intact males, females and geldings racing in Australia. Future research should be conscious of these differences when analysing population data.
研究赛马生涯趋势的研究需要一个准确比较的基准。目前，澳大利亚赛马的整体数据很少。
确定澳大利亚赛马生涯长度和生涯开始次数的范围和变化。记录并提供有关目前性别之间生涯长度和生涯开始次数差异的证据。
在 10 年的时间里，收集了纯种马的比赛数据。评估了生涯长度、生涯开始次数和每年的比赛次数。使用 R 统计软件包进行了统计分析。
共收集了 2782774 份表现记录，为 164046 匹马提供了生涯信息。该人群的职业生涯中位数和职业生涯开始数分别为 14.7 个月和 10 次。所有职业结果在性别之间均存在显著差异（P<0.001）。在 2000 年至 2010 年期间，在澳大利亚参加比赛的职业生涯超过 12、24、36 和 48 个月的纯种马比例分别为 56.65%、32.35%、16.66%和 7.74%。
在澳大利亚，完整的雄性、雌性和骟马的职业结果存在明显差异。未来的研究在分析人群数据时应注意这些差异。
