添加YZ-1复合菌对全株玉米奥玉5102青贮品质的影响

Effects of YZ-1 Compound Bacteria on Fermentation Quality of Corn Aoyu 5102 Silage

目的:为探究YZ-1复合菌对全株玉米奥玉5102青贮品质及营养成分的影响。方法:在奥玉5102青贮中添加0.08 g?t?1、0.04 g?t?1、0.02 g?t?1三种浓度的YZ-1复合菌,分别于15 d、30 d、45 d、60 d取样进行相关参数测定。结果:与空白对照组相比,YZ-1复合菌能够提高奥玉5102青贮饲料中干物质、粗蛋白含量,提高发酵体系中乳酸含量,提高稳定体系中乙酸含量,最佳添加浓度为0.02 g?t?1。结论:这对于降低生产成本,提高青贮饲料品质,并在生产中推广应用YZ-1复合菌具有重要意义。

Objective:To investigate the effect of YZ-1 compound bacteria on the silage quality and nutritional composition of corn Aoyu 5102.Method:The YZ-1 compound bacteria with concentrations of 0.08 g?t?1,0.04 g?t?1,0.02 g?t?1 were added to Aoyu 5102 silage.The relevant parameters were determined at 15 d,30 d,45 d and 60 d,respectively.Result:Compared with the blank control group,YZ-1 compound bacteria can increase the content of dry matter and crude protein in Aoyu 5102 silage,the content of lactic acid in fermentation system and the content of acetic acid in stable system,and the optimal concentration was 0.02 g?t?1.Conclusion:It was of great significance for reducing production cost and promoting the application of YZ-1 compound bacteria.
