Abstract

麦茶飲料残渣を有効利用するため,容易に流通できる100L容のポリドラム缶サイロを用い,無添加処理(対照区)および乳酸菌+アクレモニウムセルラーゼ添加処理(添加区)して麦茶飲料残渣サイレージを調製した.貯蔵後245日目にサイロを開封し,発酵品質を調査した.また,チモシー乾草と市販濃厚飼料(乾物比で4 : 1)を基礎飼料として,さらに基礎飼料の1/4(乾物比で)を麦茶飲料残渣サイレージに代替して,6頭のメンヨウに給与してサイレージの栄養価を推定した.添加区は対照区に比べてpHが有意(P<0.05)に低く,乳酸含量は有意(P<0.05)に高く,長期間貯蔵でも品質は安定に保持された.また,添加区では対照区より細胞壁の有機物成分(OCW)が有意(P<0.05)に低く,細胞内容物の有機物成分(OCC)は有意(P<0.05)に高かった.添加区と対照区の乾物中の可消化養分総量(TDN),可消化粗タンパク質(DCP),可消化エネルギー(DE)はそれぞれ67.3%と65.1%,5.0%と4.8%,13.3MJ/kgと13.0MJ/kgであった.添加区のTDN,DCPおよびDEは対照区より高い傾向を示したが,有意差は認められなかった.

A selected strain of lactic acid bacteria (LAB), <I>Lactobacillus plantarum</I> FG1 isolated from forage and acremonium cellulase (AUS) were used as additives to barley tea grounds with a drum silo for silage preparation and their fermentation quality was studied. Six Suffolk sheep were fed the basal diet with timothy hay and commercial concentration in 4 : 1 at the dry matter ratio, the nutritive value of the tea grounds silage was estimated. After 245 days of fermentation, barley tea grounds silages treated with both LAB and AUS were well preserved and exhibited significantly (P<0.05) lower pH values and organic cell wall constituent and significantly (P<0.05) higher contents of lactic acid and organic cellular contents as compared to the control silage. It was estimated that total digestible nutrient (TDN), digestible crude protein (DCP) and digestible energy (DE) of barley tea grounds silage treated with both LAB and AUS were 67.3%, 5.0% and 13.3MJ/kg of dry matter. Compared to the control silage, TDN, DCP and DE in silage treated with both LAB and AUS showed the higher tendency, however, there was no significant difference.
