Comparative study on forage qualities evaluated with grading index and relative feed value

摘要：

RFV is the most popular forage grading index used widely in the United States.Greading Index (GI) is developed by chinese scholar on the base of correcting the shortage of RFV (lack of crude protein) and inherit its virtue (including dry matter intake).The mathematical exprssion formula for GI is : GI ＝ ( ME × CP × DMI) / NDF, Where ME is metabolisable energy, MJ ; CP is crude protein, ％ DM ; DMI is voluntary forage dry matter intake, ㎏／d or g/d w0.75.
