摘 要：
通过湖北省黄冈市某奶牛场一年的DHI(Dairy herd improvement)测定结果,对生产和管理中存在的问题进行分析,以便更好地应用这一技术。结果表明,头胎牛占参测牛群的64%,产奶量及乳脂率的全年波动较大,平均SCC、产犊间隔和产奶时间分别为64万个、459 d和316 d,全年综合奶损失量772 t。热应激等问题是制约该奶牛场生产发展的瓶颈。

摘 要：
In order to apply DHI(Dairy herd improvement) technology, some problems of production and management were analyzed based on the whole year DHI(Dairy Herd Improvement) results of a dairy farm in Hubei Huang-gang. The results showed that the first calver accounted for 64% of measured herd. The whole year milk yield and milkfat percentage had large fluctuation. The average SCC was 640 000. Calving interval and lactation period were 459 and 316 days. The whole year milk loss was 772 tons. The thermal stress is one bottleneck of this dairy farm development.
