(1) Background: Bangor Sewa sheep are an economically significant livestock species on the plateau. The roles of microbiota in reproduction are complex and critical for animal health. But little is known currently about the microbiome of plateau Bangor Sewa sheep. The purpose of this study was to discover the changes in the genital tract microbiota of pre- and post-partum Bangor Sewa sheep. (2) Methods: Samples from the birth canal were obtained for 16S rRNA sequencing, three days before and after delivery, respectively. (3) Results: The results showed that there was a noticeable difference in three phyla and 74 genera between the pre- and post-parturition groups in the microbiota of Bangor Sewa sheep. The changes included a decrease in the abundance of genera related to health (unclassified_, , , , group, , , , , , etc.) and an increased abundance of negatively related genera (, unclassified, , unclassified_, _UCG_004, , , , , etc.) spp. (4) Conclusions: Microbes can serve as indicators of the physical state of Bangor Sewa sheep. These findings laid the foundation for deciphering the effects of microbial changes during birth on the reproductive health of plateau Bangor Sewa sheep.
(1) 背景：班戈瑟瓦羊是高原地区具有重要经济意义的家畜品种。微生物群在繁殖中的作用复杂且对动物健康至关重要。但目前对于高原班戈瑟瓦羊的微生物组了解甚少。本研究的目的是发现班戈瑟瓦羊产前和产后生殖道微生物群的变化。(2) 方法：分别在分娩前三天和分娩后三天采集产道样本进行16S rRNA测序。(3) 结果：结果显示，班戈瑟瓦羊微生物群中，产前和产后组在三个门和74个属上存在显著差异。这些变化包括与健康相关属（未分类的_、、、、组、、、、、等）的丰度下降，以及负相关属（、未分类的_、、未分类的、UCG_004、、、、_等）的丰度增加。(4) 结论：微生物可作为班戈瑟瓦羊身体状况的指标。这些发现为解读分娩期间微生物变化对高原班戈瑟瓦羊生殖健康的影响奠定了基础。
