Abstract

アミノ酸発酵副産液の1つであるグルタミン酸発酵副産液(monosodium glutamate fermentation byproduct:MSG)をサイレージ添加剤として利用し,イネホールクロップサイレージ(イネWCS)の発酵品質ならびにin situルーメン消化率に及ばす影響を検討した。また,MSGの作用効果に対する脱塩の影響をあわせて検討した。MSG添加サイレージは無添加サイレージよりも乳酸発酵が促進され酢酸・酪酸発酵が有意に抑制された。また,MSGはNDF含量を低減し,モミ殻,穀実,茎葉のin situルーメン消化率を著しく改善した。MSG添加による消化率の改善効果は,イネ茎葉やモミ殻の表面を覆い微生物分解を妨げるクチクラ層やスベリン層に対する化学的作用と関係していることも走査電顕によって示唆された。

The experiment of ensiling whole rice crop (Oryza sativa L.), using one liter bottle silos, was carried out to investigate whether treatment of monosodium glutamate fermentation by-product (MSG) can alter the fermentation quality and in situ rumen degradability as silage additive. The original (MSG-1) and condensed (MSG-2) MSGs were examined in comparison of the control silage. The MSG-1 and MSG-2 silages had higher concentration of lactate but lower one of acetate and butyrate than had the control (p<0.05). The two MSG additives decreased the cell wall constituents of whole rice crop and increased the in situ rumen degradability of each plant fraction including the hull, grain, leaf and stem (p<0.05). Severe softening and solubilization of the surface of the rice leaves in the MSG-1 silage was observed to enhance the microbial degradation in the rumen by scanning electron microscopy. The results in the present study indicate that the MSG can be a new silage additive to improve the fermentation quality and rumen digestibility of forage plants.
