REASONS FOR PERFORMING STUDY
Strongyle worm burdens are assumed to subclinically affect equine performance. This assumption appears to be particularly pronounced in the equine racing industry.
HYPOTHESIS
Race results of Standardbred trotters are negatively affected by high strongyle faecal egg count levels.
METHODS
Faecal samples were obtained from 213 racing Standardbred trotters, aged ≥ 2 years, and stabled at training facilities of 21 professional trainers with license at racecourses in Denmark. Strongyle egg counts were generated using a McMaster technique. Race results were recorded as the finishing position of the horse (position 1-3 vs. finishing lower) and winning purse. The effect of strongyle egg counts on performance was assessed using regression analyses.
RESULTS
Strongyle egg counts ranged from 0-3500 with a mean of 319 and a median of 150 eggs/g. Finishing in positions 1-3 was significantly associated with higher egg counts.
CONCLUSIONS
Race performance of the population of professionally trained Danish Standardbred trotters was not negatively affected by higher strongyle faecal egg count levels.
POTENTIAL RELEVANCE
The traditional frequent anthelmintic treatments of racehorses may be inordinate.
开展本研究的原因
人们认为圆线虫负荷会对马匹的表现产生亚临床影响。这一假设在赛马行业似乎尤为明显。
假设
标准蹄类赛马的比赛成绩会受到高圆线虫粪便虫卵计数水平的负面影响。
方法
从213匹年龄≥2岁、饲养在丹麦21名持有赛马场许可证的专业驯马师训练设施中的标准蹄类赛马身上采集粪便样本。使用麦克马斯特技术进行圆线虫虫卵计数。比赛成绩记录为马匹的最终名次（第1 - 3名与名次更低）和奖金。使用回归分析评估圆线虫虫卵计数对表现的影响。
结果
圆线虫虫卵计数范围为0 - 3500，平均为319，中位数为150个虫卵/克。获得第1 - 3名与较高的虫卵计数显著相关。
结论
丹麦专业训练的标准蹄类赛马群体的比赛表现并未受到较高圆线虫粪便虫卵计数水平的负面影响。
潜在意义
传统上对赛马频繁进行驱虫治疗可能过度了。
