Abstract:

This study was aimed to evaluate the effects of adding molasses and silage additives(compound bacterium preparation,mainly Lactobacillus plantarum) on fermentation quality and nutrition ingredients of “Zhang Hybrid Millet” silage.“Zhang Hybrid Millet” whole plant of raw were collected as materials, 5 groups were designed in the study:Control group was untreated,groups Ⅰ,Ⅱ,Ⅲ and Ⅳ were added 1.5‰ additives,2% molasses+1.5‰ additives, 4% molasses+1.5‰ additives and 6% molasses+1.5‰ additives to “Zhang Hybrid Millet” whole plant silage,respectively, and the ensiling period was lasted for 60 days. The results showed that:①The sensory score was affected by molasses and silage additives,and experimental groups had better sensory score, the DM content in experimental groups were significantly higher than that in control group (P <0.05),and the CP content of experimental groups were higher.②The ADF,NDF and HC contents of experimental groups (except group Ⅰ) were significantly decreased (P <0.05),while Ash content was no significantly affected (P >0.05). ③Compared with the control group,the pH and AN/TN of the experimental group were significantly decreased (P <0.05),but the lactic acid were significantly increased (P <0.05).The acetic acid content of groups Ⅰ and Ⅳ was significantly decreased (P <0.05),the propionic acid of the experimental group was significantly decreased (P <0.05),and the butyric acid and isovaleric acid of all groups were not detected. In conclusion,adding molasses and additives to the “Zhang Hybrid Millet” whole plant silage could improve the fermentation quality,we concluded that the proper supplement dosage of molasses was 4% and silage additives was 1.5 ‰ in millet silage.
