检查了个体牛乳、散装罐乳和泽西奶牛粪便的微生物群。在凉爽季节（11月、11月）和炎热季节（7月、7月）从两个农场（F1和F2）采集样品。两个农场之间和两个季节之间的产奶量和牛奶成分相似。粪便微生物群的流行类群，即瘤胃球菌科、拟杆菌科、毛螺菌科、Rikenellaceae和梭菌科，不受农场和季节的影响。假单胞菌科、肠杆菌科和链球菌科（F1 > F2）和乳杆菌科、双歧杆菌科和纤维单胞菌科（F1 < F2）的乳微生物群相对丰度在两个农场之间存在差异，葡萄球菌科、芽孢杆菌科、瘤胃球菌科和韦荣球菌科（11月<7月）和甲基杆菌科和莫拉菌科（11月> 7月）的乳微生物群相对丰度在两个季节之间存在差异。散装罐牛奶的微生物群在数值上与单个牛奶的微生物群不同。主坐标分析表明，牛奶微生物群与粪便微生物群无关。假单胞菌科和莫拉菌科的相对丰度似乎大于荷斯坦牛奶的报告表明，较高的蛋白质和脂肪含量可能会导致更丰富的蛋白水解和脂解类群在泽西牛奶。
Microbiota of individual cow milk, bulk tank milk, and feces of Jersey cows were examined. Samples were collected from two farms (F1 and F2) in cool (November, Nov) and hot (July, Jul) seasons. Milk yield and milk composition were similar between the two farms and between the two seasons. Prevalent taxa of the fecal microbiota, i.e. Ruminococcaceae, Bacteroidaceae, Lachnospiraceae, Rikenellaceae, and Clostridiaceae, were unaffected by the farm and season. Relative abundance of milk microbiota for Pseudomonadaceae, Enterobacteriaceae, and Streptococcaceae (F1 > F2) and Lactobacillaceae, Bifidobacteriaceae, and Cellulomonadaceae (F1 < F2) were different between the two farms, and those for Staphylococcaceae, Bacillaceae, Ruminococcaceae, and Veillonellaceae (Nov < Jul) and Methylobacteriaceae and Moraxellaceae (Nov > Jul) were different between the two seasons. The microbiota of bulk tank milk was numerically different from that of individual cow milk. Principal coordinate analysis indicated that the milk microbiota was unrelated to the fecal microbiota. The finding that relative abundance of Pseudomonadaceae and Moraxellaceae appeared greater than those reported for Holstein milk suggested that higher protein and fat content may result in a greater abundance of proteolytic and lipolytic taxa in Jersey cow milk.
