Abstract：
Xinjiang Brown cattle are a unique and widely distributed breed of dual-purpose cattle in the Xinjiang area of China, whose milk production performance differs from Holstein cattle. It has been known that variations in bacterial species of the gastrointestinal tract influence milk protein, fat, and lactose synthesis. However, the microbiota differences between Xinjiang Brown and Holstein cattle are less known. This study aims to compare the bacterial community composition of the rumen and feces of these two cattle breeds under the same dietary and management conditions. The 16s rRNA sequencing data and milk production of 18 Xinjiang Brown cows and 20 Holstein cows on the same farm were obtained for analysis. The results confirmed differences in milk production between Xinjiang Brown and Holstein cattle. Microbiota with different relative abundance between these two cattle breeds were identified, and their biological functions might be related to milk synthesis. This study increases the understanding of the differences in microbiota between Xinjiang Brown and Holstein cattle and might provide helpful information for microbiota composition optimization of these dairy cattle.
摘要：
新疆褐牛是我国新疆地区特有且分布广泛的两用牛种,其产奶性能不同于荷斯坦牛。众所周知，胃肠道细菌种类的变化会影响乳蛋白，脂肪，和乳糖合成。然而,新疆布朗牛和荷斯坦牛之间的微生物群差异鲜为人知。本研究旨在比较这两个牛种在相同饮食和管理条件下瘤胃和粪便的细菌群落组成。获得了18头新疆褐牛和20头同一养殖场荷斯坦奶牛的16srRNA测序数据和产奶量进行分析。结果证实了新疆布朗牛和荷斯坦牛的产奶量存在差异。确定了这两个牛品种之间相对丰度不同的微生物群，它们的生物学功能可能与牛奶合成有关。这项研究增加了对新疆布朗牛和荷斯坦牛之间微生物区系差异的了解，并可能为这些奶牛的微生物区系组成优化提供有用的信息。
