摘  要:
在晾晒24 h的苜蓿草渣中分别加入0,10,20 g/kg的甲酸进行青贮。结果表明。苜蓿草渣青贮后,无论有无甲酸,3个青贮组与原料组相比,干物质及有机物质的消化率、有机酸含量都显著的提高(P<0.01)。添加甲酸能明显降低青贮料的pH值,氨态氮、丁酸的含量并能保存更多的蛋白质。10 g/kg甲酸添加组的青贮效果最好。

摘  要:
Alfalfa residues were wilted for 24 h and added with formic acid 0,10,20 g/kg respectively. Results showed that silages had higher DM digestible rate,OM digestible rate and content of organic acid than materials. The addition of formic acid reduced pH,content of NH3-N and butyric acid obviously, and conserved more CP. The group of 10 g/kg formic acid addition achieved the best results.
