This study reports the occurrence and appearance of various reproductive tract pathologies of small ruminants diagnosed using ultrasound. An eight-year retrospective study of collected ultrasound data was carried out in Rio de Janeiro State, Brazil from September 2012 to July 2020. A total of 3463 animals from 16 sheep flocks and 10 dairy goat flocks, raised under extensive and intensive management systems, respectively, were used in the study. All animals were submitted to an ultrasound examination of their reproductive tract. Data were analyzed using Fisher’s exact test (p < 0.05), to compare disorder frequencies within and between species. Ewes (4.14%) had fewer reproductive disorders than does (8.98%), while rams (43.63%) and bucks (56.25%) presented no significant differences. Hydrometra was the most frequent finding in does, represented by 50.98% of cases; while, in ewes, recent fetal loss (22.85%) and cystic endometrial hyperplasia (20.00%) were the most frequent. In bucks, the findings showed no clear differences; while, for rams, the most frequent finding was testicular microlithiasis (75.00%). Ultrasonography offers clinically useful information about the reproductive tract via the images it provides; knowledge of which makes it possible to improve the diagnosis, therapy, and prognosis of genital pathologies.
本研究报告了使用超声诊断的小型反刍动物各种生殖道病变的发生情况和表现。2012年9月至2020年7月，在巴西里约热内卢州对收集的超声数据进行了为期八年的回顾性研究。本研究共使用了分别在粗放和集约管理系统下饲养的16个绵羊群和10个奶山羊群中的3463只动物。所有动物均接受了生殖道的超声检查。使用Fisher精确检验（p<0.05）分析数据，以比较物种内部和物种之间的疾病频率。母羊（4.14%）的生殖系统疾病比母山羊（8.98%）少，而公羊（43.63%）和公山羊（56.25%）之间无显著差异。子宫积水是母山羊中最常见的发现，占病例的50.98%；而在母羊中，近期胎儿丢失（22.85%）和囊性子宫内膜增生（20.00%）最为常见。在公山羊中，检查结果没有明显差异；而对于公羊，最常见的发现是睾丸微石症（75.00%）。超声检查通过提供的图像提供有关生殖道的临床有用信息；了解这些信息有助于改善生殖器病变的诊断、治疗和预后。
