Effects of sake lees made from steamed rice on digestion, ruminal fermentation, nitrogen balance and blood metabolites in wethers fed high concentrate diets

要 約 蒸米仕込みによる清酒粕の給与が,濃厚飼料多給条件下の緬羊の消化性,ルーメン発酵,血液性 状に及ぼす影響を in vitro 発酵試験および in vivo 代謝試験により検討した.In vitro 試験では,発酵基質の 圧ペン大麦を粗タンパク質(CP)含量が等しくなるように大豆粕(SBM),乾燥清酒粕(SLd),生清酒粕 (SLw)で一部代替した.DM 消化率は SBM, SLd, SLw 区,CP 消化率は SBM, SLw, SLd 区の順で高かっ た(P < 0.01).酢酸濃度は SBM, SLd, SLw 区,プロピオン酸濃度は SLw, SLd, SBM 区の順で高かっ た(P < 0.01).In vitro 消化率の結果に基づき,in vivo 試験では,去勢緬羊 4 頭を供試し,肥育牛用濃厚 飼料と稲わらを 7 : 3 で給与した.In vivo 試験は濃厚飼料の 10%を占める大豆粕の 0,34,69,100%を CP と TDN 含量が同等となるように生清酒粕で代替した区(C, L, M, H 区)を設け,4×4 のラテン方格法 で実施した.給餌後のルーメン内プロトゾア数は M, H 区が C, L 区よりも低かったが(P < 0.05),DM 摂 取量,見かけの消化率,窒素出納,ルーメン pH, NH3-N および VFA 濃度に差は認められず,蒸米仕込み生 清酒粕は大豆粕に代替できることが示唆された. 日本畜産学会報89 (4), 439-450, 2018 キーワード:In vitro および in vivo 消化率,清酒粕,第一胃発酵,窒素出納,緬羊
