| 摘 要： | 试验旨在研究不同水平的糖蜜和青贮添加剂（复合菌制剂，以植物乳杆菌为主）对“张杂谷”全株青贮发酵品质和营养成分的影响。以灌浆期“张杂谷”全株作为青贮原料，试验设5个处理组，即对照组（直接青贮）、Ⅰ组（1.5‰青贮添加剂）、Ⅱ组（2%糖蜜＋1.5‰青贮添加剂）、Ⅲ组（4%糖蜜＋1.5‰青贮添加剂）、Ⅳ组（6%糖蜜＋1.5‰青贮添加剂），青贮期60 d。结果显示：①试验组在感官评分上均优于对照组，试验组干物质（DM）含量均显著高于对照组（P＜0.05），粗蛋白质（CP）含量均高于对照组；②显著降低了试验组（除Ⅰ组外）青贮饲料中酸性洗涤纤维（ADF）、中性洗涤纤维（NDF）和半纤维素（HC）含量（P＜0.05），对灰分含量影响不大（P＞0.05）；③与对照组相比，试验组pH、氨态氮/总氮（AN/TN）值均显著降低（P＜0.05），乳酸显著提高（P＜0.05），Ⅰ、Ⅳ组乙酸含量均显著降低（P＜0.05），各试验组丙酸含量均显著降低（P＜0.05），在试验组和对照组中均没检出丁酸和异戊酸。综合分析认为，糖蜜和青贮添加剂能改善“张杂谷”全株青贮的发酵品质，推荐用量为4%糖蜜＋1.5‰青贮添加剂。 |

| 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. |
