摘　　要：为了发挥DHI体系在奶牛生产管理中的作用,促进奶牛健康养殖和乳品质量的提高,本研究利用DHI技术对包头某奶牛场6个月的奶牛生产情况进行了分析。结果发现,该奶牛场奶牛的乳脂率较低,体细胞数较高,一些奶牛患有严重的临床性乳房炎或隐性乳房炎。奶牛营养状况差,泌乳高峰期到达时间晚,产奶量少,存在潜在的奶损失。针对上述问题,提出了相应的解决措施。To determine and analysis the production situation of cows in Baotou cow farm during the time from January to June of 2011, Dairy Herd Improvement （DHI） data report was applied. The results suggested that these cows had lower butter fat rate and higher somatic cell count （SCC）, which displayed they had caught serious mastitis or recessive mastitis. Meanwhile, poor nutritional status and relatively late lactation peak indirectly induced milk losses. Aiming at the above problems, appropriate measures were required immediate action.
