摘要: 对黑龙江某规模化奶牛场2012年1-12月的DHI数据进行了系统的统计与分析,并将分析结果与国内外相关研究进展进行了对比。结果表明,该牛场的体细胞评分处于正常范围内,但存在泌乳高峰期到达时间晚、产犊间隔较长等问题。针对以上问题,提出了相应的改进措施。

Abstract: DHI data of the whole year of 2012 from a large-scale dairy farm in Heilongjiang Province were analyzed. And the analysis results were compared with the research advances at home and abroad. The results showed that the somatic cell score in this farm was in the normal range. But the mammary peak of cow arrived late, and the calving interval was too long. To solve the above problems, some corresponding improvement measures were put forward.
