Round bale silages of rice straw were prepared with or without addition of a selected strain of lactic acid bacteria, Lactobacillus plantarum Chikuso-1, to compare fermentation quality, dry matter intake and nutritive value. After 8 months of fermentation, silage treated with strain Chikuso-1 was better preserved than the control silage, showing a lower pH and higher lactic acid content. The mold-generating portion in the treated and control silages were 0 and 30 % on a fresh matter basis, respectively. The voluntary feed intake by sheep was higher in the treated silage than in the control. The treated silage also showed a tendency for higher contents of total digestible nutrient (43.2 vs. 41.7%) and digestible energy (7.98 vs. 7.71 MJ/kg DM) than the control silage. The results show that addition of strain Chikuso-1 improves fermentation quality, dry matter intake and nutritive value of round bale silage of rice straw.
