添加剂在四种灌木类饲用植物青贮中的应用

The Application of Silage Additives in Four Feeding Shrub

以中间锦鸡儿、尖叶胡枝子、华北驼绒藜和山竹岩黄芪为材料,比较了青宝Ⅱ号(FS)、采禾和纤维素酶(CE)3种添加剂对青贮的影响。结果表明中间锦鸡儿、尖叶胡枝子和山竹岩黄芪经青贮后,品质得到明显改善,并能得到有效保存和利用,与对照相比,添加3种添加剂后粗蛋白、粗脂肪含量有所提高,中性洗涤纤维和酸性洗涤纤维明显下降,并具有较浓的醇香气味。纤维素酶改善青贮品质的效果较好。但华北驼绒藜青贮发酵品质较差,使用添加剂后也无明显改善作用。

Using Caragana intermedia Kuang, Lespedeza hedysaroides （Pall） Kitag, Ceratoides arborescens （Losinsk） Tsien, Hedysarum fruticosum Pall as experimental materials, the effects of FS, Caihe, Cellulose on sliage were studied. The results showed that after C. intermedia, L. hedysaroides and H. fruticosum were ensiled, silage quality was obviously improved and it could be efficiently preserved and utilized. Compared with CK group, contents of crude protein （CP） and crude fat （CF） were also improved, neutral detergent fiber （NDF） and acid detergent fiber （ADF） were distinctly decreased, and the silage emitted thick alcohol flavor. Among the three kinds of additives, cellulose was with the best abilty to improve the silage quality. While fermentation quality of C. arborescens showed worse than others, and there was no significant improvement after adding additives.
