摘　　要：介绍了国际流行的粗饲料品质评定指数相对值 (RFV)、粗饲料相对质量 (RFQ)、产奶二千 (Milk2 0 0 0 )以及我国学者提出的粗饲料分级指数 (GI)与预测粗饲料采食量的粗饲料纤维物质瘤胃滞留系数 (RT IN DEX) ;揭示了RFV ,RFQ ,Milk2 0 0 0与GI四者间的联系与区别 ;详细地介绍了预测不同粗饲料RFQ参数的模型 ,并就RFQ取代RFV的可行性进行了分析。同时 ,指出了GI相对于RFV的优点 。In this paper, several international popular forge quality evaluation indices such as Relative Feed Value(RFV),Relative Forage Quality(RFQ),Milk2000,as well as Forage Grading Index(GI)and Retention Time Index of fibrous materials in the rumen(RT-INDEX)were introduced, the differences and relationships of among RFV?RFQ?Milk2000 and GI were also revealed. Furthermore,different forages predicting models for parameters of RFQ were introduced in detail,possibility of RFQ eventually replace RFV was analyzed. The latest developments of GI -test of GI and its parameter model were summarized.
