| 摘 要： | 以收获马铃薯块茎后的马铃薯茎叶为原料，以甲酸为添加剂进行青贮饲料调制试验，以期实现其饲料化利用。试验采用完全随机试验设计，在3个含水量水平（75％、65％、55％）的马铃薯茎叶分别添加梯度为0．5％、1．0％、1．5％的甲酸（FA）进行青贮，室温青贮45d后，测定其理化指标。结果表明：随甲酸添加量的增加，青贮料的感官指标呈向好趋势，添加量1．5％时，均为1级优良，发酵效果最佳；化学指标中，pH值显著降低（P〈0．05），乳酸含量升高，乙酸含量显著（P〈0．05）降低，丁酸不产出或较少产生；NH3-N／TN的含量显著（P〈0．05）下降；CP、WSC明显上升。

| Abstract: | This experiment adopted completely random design, the potato haulm with three moisture levels （a- bout 75% , 65% , 55% ） were added with different formic acid for silage. After silage 45d at room tempera- ture, measur related metrics. The results show that： when the potato haulm added formic acid content increa- ses, the performance of silage senses gradually improved, dosage 1.5 %, fermentation best, are an excellent; pH values were significantly lower （P 〈 0.05 ）, elevated levels of lactic acid, acetic acid was significantly （P 〈 0.05 ） lower, butyric acid does not produce output or less; NH3 - N/TN content was significantly （P 〈 0.05 ） decrease; dry matter, NDF and ADF content was present on the down, CP, WSC increased significant- ly. |
