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]浮稻表现出较高的干物质产量，特别是FRC14的产量为2500m2，与玉米的产量相当。在日本，出产粮食的水稻的产量取决于它的谷物。另一方面，由于细胞含量和可消化纤维的原因，在日本不产粮的漂浮大米的产量也有所下降。与其他牧草饲料一样，漂浮稻谷饲料也适用于反刍动物，首次割后的株高和干物质产量表明稻谷的再生能力不高。尤其是漂浮稻谷的株高和产量差异明显。[青贮特性]稻谷青贮一般不会产生太多的酸，本试验的结果也表明了同样的结果。FRC12青贮料的pH值为4.3，是本试验中的最低值，但其他青贮料的pH值较高。由于双重去鳞片法的结果，漂白米青贮料的产酸量高于日本产粮的其他水稻品种，而漂白米青贮料的pH值与其他水稻品种没有显著差异。

[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.
