Abstract
Guineagrass (Panicum maximum Jacq.) was ensiled in dram to estimate the dry matter intake (DMI) by breeding Japanese Black cattle. The resultant silage was "acetic acid silage" with high pH and low lactic acid content. DMI of the silage/head was higher (P<0.05) than that of an Italian ryegrass hay, but DMI/metabolic live weight was not different significantly. It was shown that guineagrass silage was satisfactorily to use as the basal diet for breeding Japanese Black cattle.
