Siloguard添加剂在尖叶胡枝子青贮饲料中的应用

Application of Siloguard on ensiled Lespedeza hedysaroides as additive

以尖叶胡枝子为原料,研究Siloguard添加剂(0.05%、0.1%、0.15%和0.2%)对胡枝子青贮饲料品质的改善效果。结果表明,添加Siloguard处理组的乳酸含量显著高于对照组(P<0.05)。通过Flieg青贮饲料评分方案得出尖叶胡枝子直接青贮饲料的发酵品质较差,评分等级为劣,而Siloguard各添加浓度处理的青贮品质均明显好于对照组,其中以添加浓度为0.2%组效果最佳。

The experiment was carried out to investigate the effects of adding Siloguard（0.05%, 0.1%, 0.15% and 0.2%） on the silage quality of the Lespedeza hedysaroides. The results showed that the treatment of Siloguard had higher lactic acid than CK （P〈0.05）. Flieg evaluation of silage showed that directly ensiled the fermentation quality was the worst, and the treated silages had better fermentation quility than CK, the addition level 0.2% is the best one of all.
