Abstract

The objective of this experiment was to evaluate chemical composition, dry matter(DM) digestibility, DM intake, relative feed value(RFV) and hay grade of imported roughage which was collected by wholesale dealer at Chungnam province in 1999. Experimental roughages includes 8 kinds of imported hays(com stover bale, tall fescue straw, green cell, bermudagrass straw, reed camarygrass straw, alfalfa bale, sugarcane bale and oat hay) and mixture hay(contro1) which was harvested at Chungnam National University experimental field. Compared with mixture hay(contro1) except for alfalfa bale, crude protein of most imported roughage was low, but NDF, ADF, cellulose and lignin compound were high. Futhermore, DM digestibility, DM intake, RFV and hay grade of imported roughage except for alfalfa bale was significantly lower than those of mixture hay(control)(P<0.05). Therefore, it is necessary to evaluate the economic value in the aspect of quality for the imported roughages. (Key words : Imported roughage, RFV, Hay grade, Nutritive value)
