摘  要：
分析了湖北省黄冈市某奶牛场2013年的DHI测定数据,包括牛群情况、产奶量、奶品质、体细胞数、泌乳天数和产奶间隔等。结果表明,该场牛群所产奶中头胎牛比例过高,三胎就产奶量不比二胎牛的高,体细胞数高,产奶牛中有38%可能患有乳房炎,产奶时间长,产犊间隔长,存在繁殖问题和饲料问题。针对测检和分析中发现的问题,提出了相应的改进措施。

摘  要：
Based on the data from DHI system of a cow farm at Hunanggang in 2013, the herds situation, milk yield, milk quality, somatic cell count, days in milk and milk interval index were analyzed. The results showed that the proportion of1st-parity cows was too high in the herds. Compared with the 2nd-parity cows, the milk yield of the 3rd-parity cows was less while the somatic cell count was too high. There were 38% cows in the herds suffering from mastitis. The days in milk and calving interval were too long. It might be induced by some problems in reproduction and feeding. Some advices on improving of production and daily management of the farm were put forward.
