OBJECTIVES Describe the association between the purchase price of Thoroughbred yearlings sold in Australia and racing performance as 2- and 3-year-olds. METHODS Race performance data of 2773 Thoroughbred yearlings sold at auction during 2003 were collected. Associations between purchase price and the probability of starting, the number of race starts and the prize money earned were examined. RESULTS In total, 2206 (79.6%) horses started a race. The mean number of race starts was six and the mean prize money earned was A$24,420. A total of 1711 (61.5%) horses earned prize money, 402 (14.4%) earned more than their purchase price, 312 (11.2%) earned more than A$40,000, the estimated cost of training, and 142 (5.1%) earned A$40,000 more than their purchase price. There was a positive association between purchase price category and the probability of starting, number of starts, earning prize money and earning greater than A$40,000 (P < 0.001). Purchase price category was negatively associated with the probability of earning greater than the purchase price (P < 0.001). The proportion of horses earning greater than the purchase price plus $40,000 was significantly different (P = 0.03) among the five price categories. CONCLUSION Yearling purchase price was positively associated with all race performance outcomes measured and researchers examining the race performance of yearlings purchased at sales should consider including purchase price when modelling. The Thoroughbred yearling market in Australia behaves in a similar manner to the United States market; owners pay a premium to enter the sport of racing and an additional premium in the quest to own a champion.
目的 描述在澳大利亚出售的纯种一岁赛马的购买价格与两岁和三岁时的比赛成绩之间的关联。方法 收集了2003年拍卖的2773匹纯种一岁赛马的比赛成绩数据。研究了购买价格与参赛概率、参赛次数和奖金收入之间的关联。结果 总共有2206匹（79.6%）马参加了比赛。平均参赛次数为6次，平均奖金收入为24420澳元。共有1711匹（61.5%）马获得了奖金，402匹（14.4%）马的奖金收入超过了购买价格，312匹（11.2%）马的奖金收入超过了40000澳元（估计的训练成本），142匹（5.1%）马的奖金收入比购买价格多40000澳元。购买价格类别与参赛概率、参赛次数、获得奖金以及奖金收入超过40000澳元之间存在正相关（P<0.001）。购买价格类别与奖金收入超过购买价格的概率呈负相关（P<0.001）。在五个价格类别中，奖金收入超过购买价格加40000澳元的马匹比例存在显著差异（P = 0.03）。结论 一岁赛马的购买价格与所衡量的所有比赛成绩结果呈正相关，研究在拍卖会上购买的一岁赛马比赛成绩的研究人员在进行建模时应考虑纳入购买价格。澳大利亚的纯种一岁赛马市场与美国市场表现相似；所有者为进入赛马运动支付溢价，并为拥有冠军马匹支付额外溢价。
