    酸制剂对黑麦草青贮饲料发酵品质和微生物菌群的影响

    Effect of Acidifiers on Microbial Flora and Fermentation Characteristics in High Dry Matter Grass Silages

      摘要
    • 摘要: 以多年生黑麦草为试验材料，通过添加甲酸或硫酸以检测酸制剂对青贮饲料发酵过程中干物质损失、酸度变化、微生物菌群变化及发酵品质的影响。青定发酵试验用1L魏工（Weck)玻璃发酵罐进行，青贮期为103d。结果表明，添加甲酸或硫酸可明显抑制正常的乳酸发酵，使发酵产物的浓度降低，且随甲酸或硫酸添加量的增加抑制增强，酸制剂可明显减少青贮饲料发酵过程中干物质的损失。

       

      Abstract: Perennial ryegrass was ensiled in 1-L laboratory jars after adding formic acid or sulphuric acid to evaluate the effects of acidifiers on DM loss, acidification, microflora and fermentation characteristics. Jars were 1 L Weck glass jars with 106 days storage period. Results showed that addition of formic acid or sulphuric acid significantly suppressed normal lactic acid fermentation, reduced the yield of fermentation products and remarkably decreased nutrients loss during the ensiling.
