【目的】探索甜高粱酒糟作为青贮原料的可能性,并通过饲喂试验研究了甜高粱青贮的增重效果,以期为甜高粱酒糟饲料化利用提供理论依据。【方法】本试验以甜高粱秸秆和酒糟为青贮原料,通过感官得分、理化指标变化评价甜高粱青贮的品质,探讨青贮菌剂对甜高粱秸秆青贮过程中pH值、粗纤维、总酸、总糖、干物质等成分的影响,并结合饲喂试验,分析了甜高粱青贮饲喂绵羊的增重效果。【结果】结果表明,甜高粱酒糟的青贮品质略低于秸秆,等级为Ⅱ级尚好,具有作为青贮原料的潜力;添加菌剂组甜高粱秸秆的总糖和还原糖含量分别比对照组高了125%和239%,粗纤维比对照组降低了21.4%,青贮菌剂可以提高总酸含量、降低青贮pH值;从饲喂试验结果来看,利用甜高粱青贮饲喂绵羊可以得到较高的日均增重,其中6月龄绵羊的日均增重大于4月龄和2月龄。6月龄绵羊的日均增重为84 g,显著高于对照组。【结论】青贮菌剂可以提高甜高粱秸秆和酒糟的发酵品质、改善营养品质,延长秸秆和酒糟的贮存时间,甜高粱青贮是一种很好的动物饲料。
Abstract：To explore the possibility of sweet sorghum distiller's grains as silage material, and to study the effect of sweet sorghum silage by feeding experiment, so as to provide theoretical basis for the utilization of sweet sorghum distiller's grains.The sweet sorghum stalks and distillers were used as silage materials, and the sweet sorghum silage quality was evaluated by sensory score and physical and chemical indexes.The effects of silage inoculants bacteria on the contents of pH value, crude fiber, total acid, total sugar and dry matter in sweet sorghum straw were studied. The effects of sweet sorghum on the weight gain of sheep were analyzed.The results showed that the silage quality of sweet sorghum distiller's grains was slightly lower than that of straw, and the grade was grade Ⅱ, which had the potential as silage. The total sugar and reducing sugar contents of sweet sorghum straw were higher than that of control group 125% and 239%, the crude fiber was21.4% lower than that of the control group. The silage inoculants bacteria could increase the total acid content and decrease the silage pH value. From the results of the feeding test, use of sweet sorghum to feed the sheep can get a higher daily average weight gain, the average daily gain of 6 months sheep was greater than 4months and 2 months. The daily average weight gain of 6 month old sheep was 84 g, which was higher than the control group.Silage inoculants bacteria can improve the fermentation quality of sweet sorghum straw and distiller's grains, improve the quality of nutrition and prolong the storage time of straw and distiller's grains.Sweet sorghum silage is a good animal feed.
