摘　　要：[Objective]To compare the effectiveness of Lactobacillus buchneri（LB）,alone or in combination with Lactobacilllus plantarum（LP）at ensiling on the fermentation,aerobic stability and nutritive value of whipgrass（Hemarthria compressa（L.f.）R.Br.）silage in 1.5-l mili-silos and 50-l plastic containers.[Method]Treatments comprised control（no additives）,LP,LB and LP ＋ LB.After 90 d of storage,overall,inoculation increased the concentration of acetic and 1,2-propanediol,but it reduced the concentrations of lactic acid,water suluble carbohydrates and enthanol.[Result]The whipgrass silages treated with LB had higher acetic acid contents than the control or LP treated silages,and were free of mold,whereas the top layers of the control or LP-treated silages were moldly.In an aerobic stability test the LB-treated silages were stable,whereas those treated with LP deteriorated.In the whipgrass silages the effects of LB made less CO 2 production and stable pH.[Conclusion]It is concluded that LB has a potential as a whipgrass silage additive that protects the silage upon aerobic exposure.[Objective]To compare the effectiveness of Lactobacillus buchneri（LB）,alone or in combination with Lactobacilllus plantarum（LP）at ensiling on the fermentation,aerobic stability and nutritive value of whipgrass（Hemarthria compressa（L.f.）R.Br.）silage in 1.5-l mili-silos and 50-l plastic containers.[Method]Treatments comprised control（no additives）,LP,LB and LP ＋ LB.After 90 d of storage,overall,inoculation increased the concentration of acetic and 1,2-propanediol,but it reduced the concentrations of lactic acid,water suluble carbohydrates and enthanol.[Result]The whipgrass silages treated with LB had higher acetic acid contents than the control or LP treated silages,and were free of mold,whereas the top layers of the control or LP-treated silages were moldly.In an aerobic stability test the LB-treated silages were stable,whereas those treated with LP deteriorated.In the whipgrass silages the effects of LB made less CO 2 production and stable pH.[Conclusion]It is concluded that LB has a potential as a whipgrass silage additive that protects the silage upon aerobic exposure.
