Poor performance in racehorses is commonly associated with subclinical diseases. This study aims to evaluate the associations between medical disorders and racing results in Standardbred trotters. The clinical records of 248 poorly performing Standardbreds were retrospectively reviewed, and their racing results were extracted from an online database, concerning the periods 3 months before and 6 months after hospitalization and the entire lifetime. Generalized linear models were used to evaluate the effects of different disorders on racing outcomes. Airway neutrophilia was associated with limiting lifetime starts and wins pre- and post-hospitalization, while mastocytosis was associated with less wins in the post-hospitalization period. Therefore, lower airway inflammation showed both short- and long-term impacts on racing performance. Severe upper airway obstructions and gastric ulcers showed associations with less placings in the post-discharge period but no long-term influence on performance. The significance of exertional rhabdomyolysis was indeterminable, yet interference with the number of starts in the post-discharge period was reported and associated with lower total career earnings. Exercise-induced pulmonary hemorrhage and cardiac arrhythmias were not associated with worse racing outcomes: therefore, their role in poor performance remains unclear.
赛马成绩不佳通常与亚临床疾病有关。本研究旨在评估标准蹄快步马的疾病与比赛成绩之间的关联。回顾性分析了248匹成绩不佳的标准蹄快步马的临床记录，并从在线数据库中提取了它们在住院前3个月、住院后6个月以及整个生命周期的比赛成绩。使用广义线性模型评估不同疾病对比赛结果的影响。气道中性粒细胞增多与限制住院前后的终身参赛次数和获胜次数有关，而肥大细胞增多症与住院后期获胜次数减少有关。因此，下呼吸道炎症对比赛成绩具有短期和长期影响。严重的上呼吸道阻塞和胃溃疡与出院后获得名次较少有关，但对成绩没有长期影响。运动性横纹肌溶解症的意义尚不确定，但据报道它会干扰出院后的参赛次数，并与职业生涯总收入较低有关。运动性肺出血和心律失常与较差的比赛结果无关：因此，它们在成绩不佳中的作用仍不清楚。
