Abstract

The superficial digital flexor tendon (SDFT) injury causes considerable wastage of racing Thoroughbreds. In this study, the heritability of SDFT injury of the forelimbs was estimated in the Thoroughbred racehorses based on the Bayesian analysis with Gibbs sampling using threshold animal models. New horse patients of SDFT injury at the age of 2-5 years accommodated in the training centers in 2005 were used for the analyses. Based on clinical data of 8198 horses, heritability of SDFT was estimated to be the order of 0.17 (posterior mode) to 0.19 +/- 0.05 (posterior mean +/- posterior SD).

摘要

指浅屈肌腱（SDFT）损伤会导致大量纯种赛马的损耗。在本研究中，基于使用阈值动物模型的吉布斯抽样贝叶斯分析，对纯种赛马前肢SDFT损伤的遗传力进行了估计。分析使用了2005年收容于训练中心的2至5岁SDFT损伤新患马病例。根据8198匹马的临床数据，SDFT的遗传力估计为0.17（后验模式）至0.19±0.05（后验均值±后验标准差）。
