添加糖蜜和青贮添加剂对"张杂谷"全株青贮发酵品质的影响
The Effects of Added Molasses and Additives on Fermentation Quality of "Zhang Hybrid Millet"Whole Plant Silage
摘要
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％ molas-ses+1.5‰ additives and 6％ molasses+1.5‰ additives to "Zhang Hybrid Millet"whole plant si-lage,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 con-trol group (P <0.05),and the CP content of experimental groups were higher.②The ADF,NDFand 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 Ⅳwas significantly decreased (P <0.05),the propionic acid of the experimental group was signifi-cantly decreased (P <0.05),and the butyric acid and isovaleric acid of all groups were not detec-ted.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 mo-lasses was 4％ and silage additives was 1.5 ‰ in millet silage.关键词
