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.
新疆褐牛是中国新疆地区特有的、分布广泛的兼用型牛品种，其产奶性能与荷斯坦奶牛不同。已知胃肠道细菌种类的变化会影响乳蛋白、脂肪和乳糖的合成。然而，新疆褐牛和荷斯坦奶牛之间的微生物群差异鲜为人知。本研究旨在比较在相同饮食和管理条件下这两个牛品种瘤胃和粪便中的细菌群落组成。获取了同一农场18头新疆褐牛和20头荷斯坦奶牛的16s rRNA测序数据和产奶量进行分析。结果证实了新疆褐牛和荷斯坦奶牛在产奶量上的差异。鉴定出这两个牛品种之间相对丰度不同的微生物群，其生物学功能可能与乳汁合成有关。本研究增进了对新疆褐牛和荷斯坦奶牛微生物群差异的理解，并可能为这些奶牛的微生物群组成优化提供有用信息。
