This study aims to identify the most common causes of equine perinatal loss up to 7 d of age in Canada.
Equine.
Necropsy reports from 360 equine perinatal loss cases were acquired from provincial veterinary diagnostic labs across Canada. Each case was classified into a basic cause (noninfectious, infectious, or unidentified) of perinatal loss, then further classified into primary and secondary categories for analysis.
Of the basic causes of perinatal loss, noninfectious causes were the most common. Bacterial causes, such as septicemia, were the most common primary diagnosis overall. was the most commonly identified bacterial species.
This study showed similar results to those of studies conducted in other countries, including having similar etiologic agents identified. The high prevalence of thyroid hyperplasia identified in this study is notable and was not reported in other, similar retrospective studies, despite being reported in locations other than Canada.
Perinatal loss can have important economic consequences for horse breeders; thus, identification of the most common causes is of interest to both veterinarians and breeders.
本研究旨在确定加拿大至出生后 7 天内马驹围产期死亡的最常见原因。
马属动物。
从加拿大各省兽医诊断实验室获得了 360 例马驹围产期死亡病例的尸检报告。每个病例都被归类为围产期死亡的基本原因（非传染性、传染性或原因不明），然后进一步分为主要和次要类别进行分析。
在围产期死亡的基本原因中，非传染性原因最为常见。细菌原因，如败血症，是总体上最常见的主要诊断。是最常鉴定到的细菌种类。
本研究结果与其他国家的研究结果相似，包括确定了相似的病因。本研究中发现的甲状腺增生高发率值得注意，在其他类似的回顾性研究中并未报告，尽管在加拿大以外的其他地区有报道。
围产期死亡会给马饲养者带来重要的经济后果；因此，确定最常见的原因对兽医和饲养者都有意义。
