Development of technics using floating rice as feed for ruminants to ensure self-supplying feed and preserve uncultivated paddy field

【干物质产量、可消化产量】浮稻干物质产量较高，其中FRC14产量达2500 m2，与玉米产量相当。日本产粮食的水稻的产量是由于它的粮食。另一方面，浮动大米的产量，由于其细胞含量和可消化纤维，在日本不生产粮食。浮米饲料与其他草料饲料一样，适合反刍动物食用。[再生能力]株高和首刈后干物质产量表明水稻再生能力不高。特别是浮稻第一次和第二次扦插的高度和产量差异明显。【青贮特点】一般来说，水稻青贮不会比其他牧草产生更多的酸，本试验的结果也表明了同样的结果。FRC12青贮的pH值最低，为4.3，其他青贮的pH值较高。双标化法的结果表明，浮米青贮的pH值与其他水稻品种无显著差异，但其产酸量明显高于日本其他产粮水稻品种。

[Dry matter yield, Digestible Yield]Floating rice indicated high dry matter yield, especially, FRC14 has 2,500m2 yield, that is equal to the yield of corn. Yield of rice that produce grain in japan is due to its grain. On the other hand, yield of floating rice, that doesn't produce grain in japan, due to its cell content and digestible fiber. Feed from floating rice is suitable for ruminants like other grass feed.[Regrowth ability]Height and dry matter yield after first cutting indicated that the regrowth ability of rice is not high. Especially the height and yield difference of floating rice between first and second cutting was clear.[Characteristics of Silage]Generally, silage from rice will not produce much acid than other grass and the result of this experiment indicated same result, too. Silage from FRC12 indicated pH4.3, the lowest value in this experiment, but other silage indicated higher value of pH.As the result of Dual Scaling Method, silage from floating rice produced much acid than that from other rice varieties that produce grain in japan, through there is no significant difference between pH value from floating rice and other rice varieties.
