摘　　要：本研究调查分析了黄冈市某奶牛场近4年的DHI数据,以期了解该场奶牛乳中体细胞数(SCC)的变化规律。结果表明,该牛群平均SCC为62万个/m L,平均体细胞评分(SCS)为4.2;胎次、泌乳阶段、产犊季节、月份和季节对SCS的影响显著。研究结果为指导奶牛场综合生产管理、制定科学应对措施及降低乳SCC提供了理论依据。In order to investigate the Variation of SCC in milk, the DHI data of a dairy farm in Huanggang district were investigated in this study. The results showed that the herd average SCC was 6.2× 10^5/mL, the SCS was 4.2 The effect of parity, lactation month, calving season, months and seasons on SCS was significant. The research was to provide theoretical basis for guiding the integrated production management of dairy farm, making scientific response measures, and reducing the SCC of milk.
