Resumo: | The change in chemical compositions and fermentation characteristics of potato pulp with Amylomyces rouxii(APS) during ensiling were compared to those of potato pulp silage without additive (CPS). Amylomyces rouxii was added as a rice malt at the rate of 1% of fresh weight. APS and CPS were ensiled in separate 900 ml silos for 3，5，7，14，28，42 and 70 days. There were no differences in the CP content throughout the ensiling period in both silage. NDF and ADF contents decreased by 5 to 7% for 70 day storage in both silage. The starch content on dry matter basis decreased from 62.0% at day 0 to 52.7% and 54.8% at day 70 in APS and CPS，respectively，and the content of APS was lower than that of CPS from day 14 to 70. The pH of APS was lower (p&lt;0.05) than that of CPS throughout the ensiling period. The concentration of lactic acid in APS was higher (pく0.05) than that in CPS from day 3 to 42. Amylommyces rouxii promoted the degradation of starch and lactic acid fermentation of potato pulp during ensiling process. アミロマイセスを新鮮物重あたり1%添加したポテトパルプサイレージ(APS)の化学成分および発酵品質の経時的変化を無添加ポテトパルプサイレージ (CPS)と比較した.サイロは900mlビンを用い，3， 5，7，14，28，42，70日間貯蔵した.どちらのサイレー ジも貯蔵期間中のCP含量に大きな変化はなく， NDFおよびADF含量は70日聞の貯蔵で5-7%程度の 減少がみられた. 原料のデンプン含量は乾物中 62.0%，70日目のCPS，APSでそれぞれ乾物中 54.8%，52.7%であり，14日目以降はAPSの方が低く 推移した. pHは貯蔵期間を通してAPSの方がCPS より低く推移し(pく0.05)，乳酸含量は42日目まで APSにおいて高く推移した(p&lt;0.05). アミロマイセ スをポテトパルプに添加することにより，サイレージ 貯蔵中におけるデンプンの分解と乳酸発酵が促進され た.
