[目的]为了方便、快捷使用DHI数据,科学指导牛场生产管理。[方法]应用SAS程序,结合CNDHI报表,对DHI数据进行分析。[结果]应用SAS程序可自动制作牛群产奶水平报告,其中包括全群牛产奶水平报告、头胎牛及经产牛产量报告,高峰日、高峰奶量报告,305d预计产奶量报告,泌乳天数大于450d牛只报告,体细胞数变化报告和连续两个月体细胞数大于50万牛只报告。[结论]应用SAS程序,可方便、快捷地使用DHI数据,提高牛场数字化管理水平。
[Objective]In order to conveniently and quickly apply DHI data, and scientificly direct the management of dairy farms. [Methods]DHI data were analyzed by SAS procedures combined with CNDHI sheets. [Results]The SAS program could automatically make milk production reports, including milk pro duction report for all cows, first lactation and second （＋） lactation cows, peak day and peak production re ports,305 projected production report. Cows milked more than 450 days report, somatic cell count variation report and cows tested somatic cell count greater than clusions]The application of SAS program could make digital information in dairy farms. 500,000 in consecutive two months reports. [Con reports easily and improve the management level of
