摘要
目的:研究不同青贮处理对荞麦秸秆的感官性状及营养品质的影响.方法:将不同比例的玉米面、米糠、糖蜜和玉米秸秆加入荞麦秸秆中混合青贮,从感官、pH值、氨态氮和营养成分等方面进行分析评价.结果:与对照组相比,各处理组均不同程度地改善了青贮品质.从pH值和氨态氮含量来看,30％混合玉米青贮组效果最好;4％米糠组的粗蛋白(5.74％)含量显著高于其他处理组(P＜0.05);5％糖蜜组和30％混合玉米青贮组的粗脂肪含量显著低于其他三个处理组(P＜0.05).结论:综合比较感官性状和营养品质,5％糖蜜和4％米糠处理条件下,青贮品质总体效果较好,是荞麦秸秆饲用前处理的可行途径之一.
Abstract
[Objective]To study the effects of different silage treatments on sensory properties and nutritional quality of buckwheat straw.[Method]Adding different proportions of com flour,rice bran,molasses and com straw into buckwheat straw mixed silage,and analyzing and evaluating from the aspects of sensory,pH,ammonia-cal nitrogen and nutrient component.[Result]Comparing with the control group,the silage quality was improved in different degrees in each treatment group,and the effect of 30％mixed com silage group was the best in terms of pH value and ammoniacal nitrogen content.The crude protein content(5.74％)in 4％rice bran group was signif-icantly higher than that in other groups(P＜0.05).The crude fat content of 5％molasses group and 30％mixed corn silage group was significantly lower than that of the other three treatment groups(P＜0.05).[Conclusion]The overall effect of silage quality under 5％molasses and 4％rice bran treatment is better,which is one of the feasible ways to treat buckwheat straw before feeding.
