Echocardiography has become a routine non-invasive cardiac diagnostic tool in most species. Accurate measurement of cardiac dimensions requires reference values, which are poorly documented in goats. The aim of the present study was to test the inter-day repeatability and to establish the reference values of two-dimensional (2D-) and time-motion (M-) mode echocardiographic variables in healthy adult Saanen goats. Six goats were investigated three times by the same observer at one-day interval using a standardised 2D- and M-mode echocardiographic protocol. The intra-observer inter-day repeatability was tested using analysis of variance, calculation of the coefficient of variation and confidence intervals. A single echocardiographic examination was performed in six other goats, and values obtained in the 12 goats were used to establish the 2D- and M-mode echocardiographic reference values in healthy adult female Saanen goats. Statistical analysis revealed a good inter-day repeatability of the echocardiographic cardiac measurements. Echocardiographic reference values obtained in healthy adult Saanen goats seemed slightly higher than those reported in healthy Swedish domestic goats and were similar to those reported in healthy adult sheep.
超声心动图已成为大多数物种中常规的非侵入性心脏诊断工具。准确测量心脏尺寸需要参考值，但在山羊中记录不佳。本研究的目的是测试 2D- 和时间-运动 (M-) 模式超声心动图变量的日内重复性，并为健康成年萨能奶山羊建立参考值。同一位观察者在一天的间隔内使用标准的 2D- 和 M-模式超声心动图方案对 6 只山羊进行了 3 次检查。使用方差分析、变异系数的计算和置信区间来测试观察者内的日内重复性。另外 6 只山羊只进行了一次超声心动图检查，将这 12 只山羊获得的值用于建立健康成年雌性萨能奶山羊的 2D- 和 M-模式超声心动图参考值。统计分析显示，超声心动图心脏测量的日内重复性良好。在健康成年萨能奶山羊中获得的超声心动图参考值略高于在健康瑞典家山羊中报道的值，与在健康成年绵羊中报道的值相似。
