Abstract：
Goats are often affected by respiratory diseases and, despite ultrasonography can assess lung consolidations in several species, it is rarely used in these animals. So, this study evaluated the effectiveness of on-farm lung ultrasonography in detecting lung consolidations on 27 goats. The goats, scheduled for slaughter, underwent complete clinical examinations and lung ultrasonography. For the latter, both sides of the thorax were divided in four quadrants and examined using convex and linear probes before and after shaving the hair. Each quadrant was classified based on presence/absence of lung consolidation and maximum consolidation\'s depth (4-point scale: 0 healthy; 1 depth < 1 cm; 2 depth < 3 cm; 3 depth > 3 cm). The lungs were examined at necropsy, 66% of goats exhibited lung consolidations and sensitivity (83%-89%), specificity (100%), and κ coefficient values (0.67-0.72) were high with all techniques. An higher (p ≤ 0.01) percentage of class 1 lesions were found at necropsy compared to all the ultrasonographic techniques. All the ultrasonographic techniques effectively detected lung consolidation deeper than 1 cm. So, ultrasonography seems an effective tool for lung examination in goats with chronic pneumonia. The examination using the linear or the convex probes without shaving the hair could be a promising tool for the on-field diagnosis of pneumonia, although further research on larger sample sizes are necessary to validate these findings.
摘要：
山羊经常受到呼吸道疾病的影响，尽管超声检查可以评估几个物种的肺巩固，它很少用于这些动物。所以,这项研究评估了农场肺部超声检查对27只山羊肺部巩固的有效性。山羊,预定屠杀,接受了完整的临床检查和肺部超声检查。对于后者,将胸部的两侧分为四个象限，并在剃毛之前和之后使用凸形和线性探针进行检查。每个象限根据存在/不存在肺实变和最大实变深度进行分类(4点量表:0健康;1深度<1cm;2深度<3cm;3深度>3cm)。尸检时检查了肺部，66%的山羊表现为肺巩固和敏感性(83%-89%)，特异性（100%），在所有技术中，κ系数值（0.67-0.72）都很高。与所有超声检查技术相比，尸检发现的1类病变百分比更高（p≤0.01）。所有超声检查技术均可有效检测到深度超过1cm的肺实变。所以,超声检查似乎是山羊慢性肺炎肺部检查的有效工具。在不剃毛的情况下使用线性或凸探针进行的检查可能是现场诊断肺炎的有希望的工具，尽管需要对更大的样本量进行进一步的研究来验证这些发现.
