不同封口时间对胡萝卜苗青贮饲料品质的影响
|
摘要
为探讨不同封口时间对胡萝卜苗青贮饲料品质的影响,研究采用单因素试验设计,将胡萝卜苗切割装袋后,分别在24、48、72、96 h后封口,试验共分为4组,每组3个重复。不同封口时间对胡萝卜苗青贮饲料的p H、DM、CP、NDF、ADF、Ash影响的差异不显著(P>0.05),但综合考虑感官评定标准,进行胡萝卜苗青贮时宜在48 h之内完成封口。
In order to investigate the effect of different sealing time of carrot seedlingsilage quality, this experiment used a single factor that carrot seedlings were cut after bagging, 24, 48, 72, 96 h after sealing, this test would be divided into four groups, three replicates in each group. With the sealing time of carrot seedling silage, differences in p H, DM, CP, NDF, ADF, Ash had not significant difference(P>0.05), but considering the standard of sensory evaluation, carrot seedlings sealing should be completed within 48 h in silage season.
