Abstract: This experiment investigated the effects of pleurotus eryngii mushroom bran and plant lactobacillus on the aerobic stability and in vitro fermentation characteristics of whole-plant corn silage. The corn variety Kangnongyu 999 was used as silage material,and a mixture of mushroom bran and plant lactobacillus was added for silage. Sample were analyzed after 60 days of ensiling. The nutritional quality,fermentation quality,aerobic stability,and in vitro digestion effect of each fermentation group were studied before and after ensiling. The results showed that the fermentation nutritional quality,acetic acid content,and aerobic stability time of mixed silage were superior to those of the whole plant corn silage alone. In the in vitro fermentation experiment,the addition of 10% pleurotus eryngii mushroom bran and 0.02 g·kg-1 plant lactobacillus significantly increased the CP degradation rate. Thus,adding pleurotus eryngii mushroom bran and plant lactobacillus to the entire corn silage improved the silage quality and aerobic stability,improved in vitro fermentation characteristics,and increased CP degradation rate. Taking all factors into consideration,a mixed silage of 90% whole plant corn,10% pleurotus eryngii mushroom bran,and 0.02 g·kg-1 plant lactobacillus can achieve better results.

摘要: 试验旨在研究杏鲍菇菌糠和植物乳杆菌对全株玉米青贮有氧稳定性和体外发酵特性的影响。以玉米品种‘康农玉999’为青贮材料,添加杏鲍菇菌糠和植物乳杆菌混合青贮。青贮60 d后取样分析。对青贮前后发酵各组营养品质、发酵品质、有氧稳定性和体外消化效果进行研究。结果表明:青贮后,混合青贮发酵营养品质、乙酸含量和有氧稳定性时间优于全株玉米单独青贮;体外发酵试验中,添加10%杏鲍菇菌糠+植物乳杆菌0.02 g·kg-1组CP降解率显著提高。由此可见,在全株玉米青贮中添加杏鲍菇菌糠和植物乳杆菌提高了青贮品质和有氧稳定性,改善了体外发酵特性,提高了CP降解率。综合考虑,以90%全株玉米+10%杏鲍菇菌糠+植物乳杆菌0.02 g·kg-1混合青贮时可获得较好的效果。
