| 摘 要： | 为了探索体细胞评分与牛奶品质及产量相关性,本研究收集了宁夏地区某4个奶牛场的DHI数据,利用SAS软件对SCS与牛奶中乳蛋白率、乳脂率、奶产量、尿素氮等指标的相关性进行统计分析.结果表明,SCS与日产奶量呈显著负相关(P<0.05),与乳脂率、乳蛋白率和尿素氮没有显著的相关性.

| Abstract: | In order to explore the correlation among somatic cell score(SCS), milk quality and yield, DHI data of a dairy farm in Ningxia were collected. Then the correlation between SCS and milk lactose, milk protein, milk fat rate and milk yield was statistically analyzed by SAS. The results showed that SCS was significantly negatively correlated with daily milk yield(P < 0.05), and had no significant correlation with milk fat rate, milk protein rate and urea nitrogen. |
