A linear assessment trait evaluation system is proposed to allow quantitative description of the static conformation of the horse. Measurements were made on 27 selected traits. The system was tested initially for repeatability of measurements on 4 horses. Twenty-one of the selected traits were satisfactory and 6 proved unsatisfactory in terms of reproducibility. A population of 101, superior 2- and 3-year-old Thoroughbreds and 19 premium Thoroughbred stallions were similarly assessed. More than 65% of the traits exhibited large (CV > 10%) phenotypic variation within the sampled population. It is proposed that such a system of static conformation assessment, in conjunction with a similar system for dynamic linear assessment, would provide useful quantitative selection criteria in the description and breeding of horses.
提出了一种线性评估性状评价系统，以对马的静态体型进行定量描述。对27个选定性状进行了测量。该系统最初在4匹马身上进行了测量重复性测试。在可重复性方面，选定的21个性状令人满意，6个性状不令人满意。对101匹优质的2岁和3岁纯种马以及19匹优质纯种种马进行了类似评估。超过65%的性状在抽样群体中表现出较大（CV>10%）的表型变异。有人提出，这样的静态体型评估系统，结合类似的动态线性评估系统，将为马的描述和育种提供有用的定量选择标准。
