| 摘 要： | 以油蒿(Artemisia ordosica)为原料,通过加入添加剂采禾青贮和直接青贮,探讨油蒿的可青贮性。结果表明:直接青贮和添加剂青贮后感官性状的评分分别为17和18分,达到了优良等级。添加剂青贮pH为4.59,直接青贮pH为5.15,直接青贮乳酸和乙酸占总酸的百分比高于添加剂青贮,而丙酸和丁酸占总酸的百分比为添加剂青贮高于直接青贮,氨态氮占总氮的百分比也表现为添加剂青贮高于直接青贮。通过费氏评分法的评价结果来看,直接青贮为41分合格,而添加剂青贮为39分不合格。综合感官性状、发酵品质,油蒿可以采用青贮方式进行保存,且直接青贮更好。

| Abstract: | Artemisia ordosica was used as silage with and without additives.Results showed that showed that the properties of silage were marked as 17 and 18 by sensory evaluations without additives and with additives,respectively.The pH value of silage without additives and silage adding additives were 5.15 and 4.59 respectively.Additives can increase pH value,lactic acid(LA) and acetic acid(AA) contents.Silage without additives has less propionic acid(PA) and butyric acid(BA) than those with additives.The results of Flieg’s evaluation showed that the silage with no additive was qualified silage.Comprehensive sensory evaluation and fermentation quality indicate that Artemisia ordosica can make silage without additive. |
