To investigate the effect of moisture content on the silage fermentation of tropical grasses, guineagrass (Panicum maximum Jacq.) wilted for 6 hours was ensiled into laboratory bag silos. The silos were kept in the room temperature, and then were opened on 2, 7, 15, 30 and 90 days after ensiling. The moisture contents were ca. 70% in wilted silage and ca. 80% in non-wilting (control) silage. In the initial stages of ensiling, pH of the wilted silage was slightly lower than the control silage, but at the end there was no difference. Lactic acid content of the wilted silage was significantly higher than control silage throughout ensiling. On the other hand, wilted silage was significantly lower than control silage in acetic acid, butyric acid and volatile basic nitrogen (VBN) contents. These results indicated that the light-wilting increased lactic acid and decreased acetic acid, butyric acid and VBN. Therefore, high moisture content may be one of the reasons why the acetic acid silage is produced from tropical grasses.
