3种复合菌剂对全株玉米青贮品质的影响

Effect of three compound bacterial agents on the quality of whole corn silage

为探究复合菌剂对全株玉米裹包青贮感官品质和营养成分的影响,设置添加先锋、台湾芯来旺、微贮博士3种复合菌剂为3个处理组,不添加复合菌剂为对照组,30d后对全株玉米青贮饲料进行色泽、气味、水分、pH值等感官评定,测定营养成分。结果表明:3种复合菌剂均可以提高全株玉米青贮料的品质,其青贮饲料在粗蛋白、pH值、水分、气味、色泽、质地等方面均明显优于对照组,其中添加先锋复合菌剂(R1)全株玉米青贮饲料品质等级达到优等。

The effects of compound bacterial agents on the sensory quality and nutritional components of whole corn silage were studied,to provide reference for whole plant corn wrapped silage in Hunan.Three compound bacterial agents(Xianfeng,Taiwan xinlaiwang and Dr.micro storage),were added as three treatment groups,and no compound bacterial agent was added as the control group.After 30 days,the color,odor,moisture and pH value of the whole corn silage were evaluated,and the nutritional components were determined.The results showed that the three compound bacterial agents could improve the quality of whole corn silage.The silage was significantly better than the control group in crude protein,pH value,moisture,odor,color and texture.The quality grade of whole corn silage added with pioneer additive(R1)was excellent.
