摘要
为了解牛场应用生产性能测定（DHI）技术的效果，2015年1-12月应用奶牛生产性能测定体系对新乐市某奶牛场所有泌乳牛进行了测定和分析。结果表明：该场应用DHI报告指导奶牛实际生产工作，牛群日产奶量、高峰奶量、乳脂率、乳蛋白率等不断提高，体细胞数逐步降低，对存在的产奶高峰日延后及繁殖问题和围产期奶牛管理问题，经过分析提出了相应的改进措施，使该场的管理水平和经济效益得到提高。
To understand the effect of dairy farm using DHI. The production performance of all dairy cows in a farm in Xinle were measured and analyzed from January to December, 2015. Results showed that： the farm used DHI to guide production, the daily yield, milk fat rate and milk protein rate of cows were continuously improved, somatic cell count was gradually reduced, the milk peak day was delayed. As for reproductive issues and perinatal management issues exist for analysis of measurement problems, a lot of corresponding improvement measures were proposed. The effect analysis of dairy farm using DHI provided a theoretical basis for disseminating DHI.
