Milk oligosaccharides (MOs) have unique health benefits for newborns, and MOs are important components in mammalian milk. The present study was conducted to provide a comprehensive analysis of MOs in important domestic animals, including goats, cows, camels and sheep. The comparison with human MOs was conducted simultaneously. Furthermore, analysis of the relative abundance of sheep MOs among different breeds (Hu sheep, East Friesen sheep, East Friesen-Hu crossbred sheep) and lactation periods (colostrum, mature milk) was performed. In general, 35, 24 19, 26, and 16 MOs were identified in human, goat, bovine, camel and sheep milk, respectively. The type of sheep MOs was not greatly influenced by the breeds and lactation period. Hu sheep colostrum had the highest abundance of MOs among six sheep milks, followed by East Friesen sheep colostrum, while East Friesen-Hu crossbred sheep mature milk had the lowest abundance of MOs. These findings provide evidence for the potential value of MOs from domestic animal milk for the commercial applications.
牛奶低聚糖（MOs）对新生儿具有独特的健康益处，并且是哺乳动物奶中的重要成分。本研究旨在对包括山羊、奶牛、骆驼和绵羊在内的重要家畜中的 MOs 进行全面分析。同时与人类 MOs 进行了比较。此外，还分析了不同品种（湖羊、东弗里生羊、东弗里生-湖羊杂交羊）和泌乳期（初乳、成熟乳）的绵羊 MOs 的相对丰度。总体而言，人乳、山羊乳、牛乳、骆驼乳和绵羊乳中分别鉴定出 35、24、19、26 和 16 种 MOs。绵羊 MOs 的类型受品种和泌乳期的影响不大。六种绵羊乳中，湖羊初乳的 MOs 含量最高，其次是东弗里生羊初乳，而东弗里生-湖羊杂交羊成熟乳的 MOs 含量最低。这些发现为家畜乳中的 MOs 在商业应用中的潜在价值提供了证据。
