silages of this material with napiergrass (NG), silvergrass (SG), pineapple leaves (PAL), sweet potato leaves (SPL), milk bush (MB), sugar cane tops (SCT) and sugar cane bagass (SCB) were made. Mixing ratio was one to one. Ten percent sugar cane molasses, on wet basis, before diluting with twofold of water was added to these mixed materials to be ensiled in order to improve their fermentation. Aliquot amount of each mixed materials at ensiling time and fer mented samples at 2,4,7,21 and 70 days of fermentation were taken for the determination of pH, moisture content, organic acid and soluble carbohydrate to assess their fermentation and quality. Each mixed silage showed very significant decrease in pH value within 7 days of fermentation. The PH values at 70 days of preservation ranged from 3.9 to 4.0,except 4.5 for LLDW-SCT silage. Lactic acid concentrations varied from 1.2% to 3.4%. The values for the mixed silages of LLDW-NG and LLDW-SCT at 7 days of fermentation were higher than those for the other treatments, with the respective figures being 3.0%, 2.5% and 2.6%. Thereafter until 70th day, no significant changes of lactic acid levels in these three mixed silages were observed, while the values for the treatment groups of LLDW-SPL and LLDW-PAL showed gradual increase with advances in the fermentation stages. Concentrations of acetic acid gave no changes at 7 days of ensiling with a range from 0.07% to 0.12%. Small amount of butyric acid was found in 21 day LLDW-SCT and 70 day LLDW-PAL silages. Disappearance rate of soluble carbohydrate at 70 days of preservation was in a range from 70% to 81%. From the evaluation of criteria such as pH, composition of organic acid, color, flavor and the sense of touch at 70 days of fermentation, it was found that all treatment groups, except LLDW-SCT and LLSW-PAL treatments, result in good quality silages. Especially, mixtures of LLDW with SG and NG were found to produce better mixed silages than other treatment combinations.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3970"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.

内容記述 ギンネムを飼料資源として家畜に有効的に利用するための基礎的知見を得るために, 実験用サイロを用いてギンネムを主とした混合サイレージの調製を行なった。すなわち, 試験区としてギンネム茎葉部と他材料のネピアグラス, ススキ, パイン葉, カンショツル, アオサンゴ, サトウキビ梢頭部およびバガスなどを1 : 1の割合で混合し, 糖蜜を10%添加することによって7種類のサイレージを調製した。これらの試験区は, それぞれ詰め込み時および詰め込み後, 2,4,7,14,21および70日間経過した後, 各サイロを開封してpH, 水分, 有機酸組成および可溶性炭水化物などを測定することによって質的検討を行ない, 次の結果を得た。pH値は, 各試検区とも詰め込み後7日目以内の低下が激しく, 70日目における値はサトウキビ梢頭部混合区の4.9以外は3.9∿4.0の範囲にあった。各試験区における有機酸組成では, 70日目の乳酸生成量は, 約1.2∿3.4%の範囲にあった。そのうち, ススキ, ネピアグラスおよびバガスなどの混合区の埋蔵初期の7日目における乳酸生成量は, それぞれ約3.0,2.5および2.6%と他区と比較して高い値を示し, その後70日目までの著しい変化はほとんど認められなかった。一方, カンショツルおよびパイン葉混合区などでは, 埋蔵日数に伴なって漸次増加の傾向を示していた。酢酸は, 各試験区とも7日後の変化がほとんどみられず0.07∿0.12%の範囲にあった。酪酸は, サトウキビ梢頭部混合区で21日目に, パイン葉混合区では70日目に若干の生成が認められた。各試験区における可溶性炭水化物の減少率は, 70日目で約71∿81%であった。pH, 有機酸組成, 色, 香りおよび触感などにより70日目における各試験区のサイレージの品質を評価した結果, サトウキビ梢頭部およびパイン葉混合区が他区と比較してやや劣っていたが, 各試験区ともほぼ良質のサイレージが得られた。とくに, ススキおよびネピアグラス混合区は, 他区と比較して発酵促進効果が良好であり良質のサイレージが調製された。

内容記述 To obtaine some basic information on the effective utilization of Leucaena leucocephala de Wit (LLDW) as a livestock feed, 7 mixed silages of this material with napiergrass (NG), silvergrass (SG), pineapple leaves (PAL), sweet potato leaves (SPL), milk bush (MB), sugar cane tops (SCT) and sugar cane bagass (SCB) were made. Mixing ratio was one to one. Ten percent sugar cane molasses, on wet basis, before diluting with twofold of water was added to these mixed materials to be ensiled in order to improve their fermentation. Aliquot amount of each mixed materials at ensiling time and fer mented samples at 2,4,7,21 and 70 days of fermentation were taken for the determination of pH, moisture content, organic acid and soluble carbohydrate to assess their fermentation and quality. Each mixed silage showed very significant decrease in pH value within 7 days of fermentation. The PH values at 70 days of preservation ranged from 3.9 to 4.0,except 4.5 for LLDW-SCT silage. Lactic acid concentrations varied from 1.2% to 3.4%. The values for the mixed silages of LLDW-NG and LLDW-SCT at 7 days of fermentation were higher than those for the other treatments, with the respective figures being 3.0%, 2.5% and 2.6%. Thereafter until 70th day, no significant changes of lactic acid levels in these three mixed silages were observed, while the values for the treatment groups of LLDW-SPL and LLDW-PAL showed gradual increase with advances in the fermentation stages. Concentrations of acetic acid gave no changes at 7 days of ensiling with a range from 0.07% to 0.12%. Small amount of butyric acid was found in 21 day LLDW-SCT and 70 day LLDW-PAL silages. Disappearance rate of soluble carbohydrate at 70 days of preservation was in a range from 70% to 81%. From the evaluation of criteria such as pH, composition of organic acid, color, flavor and the sense of touch at 70 days of fermentation, it was found that all treatment groups, except LLDW-SCT and LLSW-PAL treatments, result in good quality silages. Especially, mixtures of LLDW with SG and NG were found to produce better mixed silages than other treatment combinations.
