摘　　要：本试验依据康奈尔大学净碳水化合物净蛋白质体系(CNCPS)和CPM-Dairy配方软件的技术思想,对几种我国常用奶牛饲料原料进行聚类分析。采用近红外分析和实验室分析对4大类[苜蓿干草、干酒糟及其可溶物(DDGS)、玉米粉和玉米青贮],共1 169个我国常用奶牛饲料样品的16类指标进行测定,用聚类分析的方法对样品科学分类。结果表明,用聚类分析的方法,根据不同饲料的特点,分别将苜蓿干草分为12类、DDGS分为10类、玉米粉分为5类、玉米青贮分为6类。综合得出,聚类分析的方法得出结果符合CPM-Dairy饲料数据库要求,且可信度高。Based on the technique theories of Cornell Net Carbohydrate and Protein System （CNCPS） and CPM-Dairy formula software,this study was conducted to do clustering analysis for several regular raw materials of Chinese dairy feed.By the methods of near infrared analysis and laboratory analysis,sixteen types of parameters for 4 classifications （dry alfalfa hay,distiller＇ s dried grains with solubles （DDGS）,corn meal and corn silage）,totally 1 169 regular feed samples for Chinese dairy were determined,and the samples separated into different categories by clustering analysis.The results showed that dry alfalfa hay,DDGS,corn meal and corn silage were separated into 12,10,5 and 6 categories,respectively.In conclusion,the results determined by clustering analysis are corresponded to the requirement of raw material database of CPM-Dairy,and are quite reliable.
