Firstly, the dissertation chose the species of additives and decided the concentrations of addition. Then experiments had been carried out by using corn stover ensiled with those additives under ideal ensiling condition. After each storage and fermentation period, silage was removed from silo tin and analyzed for DM, pH, DM digestibility, NDF digestibility, organic acid composition and content, DM Recovery, silage composition, ammonia-N-to-total-N ratios of silage. Those results had been used to evaluate the effects of those additives on corn stover silage.

课题首先根据查阅的大量文献资料，确定要研究的添加剂种类和添加剂量，然后在玉米秸秆原料中添加所选的添加剂，在适宜的青贮条件下进行青贮饲料的调制试验，将经过一定发酵时间的青贮饲料开封后，通过测定玉米秸秆青贮饲料的干物率、pH值、有机酸含量及组成、干物质消失率、NDF瘤胃降解率、干物质回收率、青贮化学成分、氨态氮占总氮的比例等指标，这些测定分析结果用来确定不同添加剂对玉米秸秆青贮饲料质量的影响。
