第一胃刺激用具(RF)の投与およびサイレージ調製したビール粕の給与が,圧ペン大麦主体の濃厚飼料多給与条件下の去勢牛から発生するメタンに及ぼす影響について検討した.供試動物は,ホルスタイン種去勢雄牛4頭(平均体重698kg),給与飼料は,チモシー乾草(TH),ビール粕サイレージ(BS),圧ペン大麦および大豆粕を用いた.給与量は,代謝エネルギー換算で維持要求量とした.処理は,TH配合の飼料とBS配合の飼料のRF無投与処理,それぞれの飼料給与時にRFを1頭あたり3個ずつ,経口的に第一胃へ投与したRF投与処理の合計4処理とした.その結果は,以下の通りであった.1)乾物の消化率は,BS配合の飼料給与時がTH配合の飼料給与時に比べて有意に低く(P<0.01),RFを投与することでは有意に高くなった(P<0.05).2)一日可消化有機物1kg摂取量あたりのメタン発生量は,飼料間に差がなかったが,RFの投与では有意に減少した(P<0.01).3)第一胃内容液のpHは,いずれの処理においても差がなかった.プロトゾア数は,飼料間に差がなかったが,RFの投与では有意に減少した(P<0.05).4)液相部と固相部の第一胃通過速度は,RFを投与すると有意に高まった(P<0.05).これらの結果から,圧ペン大麦主体の濃厚飼料多給与条件下の去勢牛から発生するメタンは,BS配合の飼料を給与しても影響がなかったが,RFを投与すると消化率を低下させることなく,メタン発生量を抑制することが可能であった.

Summary : The objectives of this study were to investigate the fermentation quality characteristics of Chineria-Mama whole crop rice silage and to examine the effect of addition of fermented juice of silage extract (FJSE) and fermented juice of epiphytic lactic acid bacteria (FJLB) on the fermentation quality. Rice plant (Oryza sativa L. line, Chineria-Mama) was cultivated by using conventional methods and was harvested on September 8 (Sept-cutting) and October 6 (Oct-cutting), 2006. The rice plants were cut with a cutter blower into 1-3 cm pieces and were crammed into plastic pouches without (control) or with 1 % of FJSE (FJSE treatment) or FJLB (FJLB treatment) in the fresh matter. All silages were maintained indoors and opened after 1 month. FJSE and FJLB were prepared according to the following method. 100 g of the cut fresh Chineria-Mama silage and Chineria-Mama rice plant were macerated with 500 mL of water and 10 g granulated sugar was added. The mixture was incubated anaerobically at room temperature for 2 days, and then filtered through quadruple layers of cheesecloth. The filtrate was collected in a plastic bucket and blended with 10 g granulated sugar. There was no remarkable difference in crude protein, ether extracts and neutral detergent fiber content between the Sept-cutting rice plant and the Oct-cutting rice plant. The non fibrous carbohydrates content of Chineria-Mama rice plant was 33.1% Sept-cutting and 33.6% Oct-cutting in the dry matter. The pH values for silage of control, FJSE treatment and FJLB treatment were the range of 3.6-3.8. Moisture contents for all silages of Sept-cutting were higher than those of Oct-cutting (P<0.01). The lactic acid contents in the fresh matter of all silages were more than 1 %, and that of FJSE treatment silage was lowest (P<0.05) at Sept-cutting and Oct-cutting. Propionic acid was observed only in FLSE treatment silage (P<0.01). Butyric acid contents were low in the silage of control, FJSE treatment and FJLB treatment. There was no large difference in volatile basic nitrogen content among three treatment silages. The present results suggest that the fermentation quality of Chineria-Mama whole crop rice silage is good, and the addition of FJSE and FJLB prepared in this experiment can not improve on the lactic fermentation of silage.
