Abstract

水田を有効利用した飼料作物生産技術の開発を目的とし,良質浮イネサイレージの調製法を確立するため,耐湿性に優れ,サイレージ発酵品質の良好な暖地型マメ科牧草ファジービーン(Macroptilium lathyroides (L.) Urb.以下Pbと略)の混合が浮イネ(Oryza sativa L.)サイレージの発酵品質ならびに粗タンパク質(CP)含量改善に及ぼす影響について検討を行った。実験用小型サイロを用いた試験において,浮イネ(Gour Kajol (以下FRC8)およびRayada(以下FRC14)の2系統)の原料可溶性炭水化物含有率は10%以上と高く, V-SCOREも80点以上の値となった。Pb混合割合の高い25%および50%混合区でCP含量および乳酸含有率が高まり, pHの低下が認められ, V-SCOREも浮イネ単独のものより高い値となった。バッグサイレージにおいても浮イネ(FRC8)サイレージのV-SCOREは約92点と高く, Pb混合によりCP含量およびV-SCOREが高い値となった。ホルスタイン種搾乳牛における10分間のサイレージ採食量は,Pb>Pb混合浮イネ>浮イネであった。

Fermentation quality and palatability of floating rice plant (Oryza sativa L.), phasey bean (Macroptilium lathyroides (L.) Urb.), and mixed silages were investigated for ensiling in laboratory silos and bag silos. In Experiment 1, floating rice plant (strain Gour Kajol (FRC8) or Rayada (FRC14)) and phasey bean were ensiled in laboratory silos (1-litre polyethylene silo, about 700g) with varying compositions of the materials (0, 12.5, 25, 50 and 100% phasey bean on a fresh weight basis). After storing for 47 days, the silos were opened and silage samples were analyzed for fermentation quality and V-SCORE calculation. Floating rice plant materials showed high mono- and oligo-saccharide content, and the resulting silages showed high fermentation quality. Mixing phasey bean into the floating rice plants improved the crude protein content and fermentation quality of silage, as indicated by higher lactic acid production. In Experiment 2, FRC8 and phasey bean were ensiled in bag silos (about 10kg) with varying compositions of the materials (0, 50 and 100% phasey bean on a fresh weight basis). Silages were fed to Holstein cows and were tested for palatability by the cafeteria method. Floating rice plant silage, phasey bean silage and mixed silages showed high fermentation quality. The dry matter intake was highest for phasey bean silage>mixed silage of phasey bean into floating rice plant>floating rice plant silage.
