摘　　要：【目的】研究添加甜叶菊渣对绢蒿青贮发酵品质及苦味掩盖(去除)的影响,为新疆天山北坡绢蒿资源的充分利用提供理论基础。【方法】以伊犁绢蒿与甜叶菊渣为原料,按照鲜重质量比10∶0(CK处理)、9∶1(T_(1)处理)、8∶2(T_(2)处理)、7∶3(T_(3)处理)混合袋装青贮发酵60 d,分析营养成分、有机酸含量、发酵品质及小鼠饮水的数据(水饮用量、浸提液饮用量)。【结果】各混合比例青贮的pH值、氨态氮/总氮和丙酸含量相比对照组显著降低(P<0.05);随着甜叶菊渣添加比例的增加,各混合处理的粗脂肪、中性洗涤纤维显著低于对照组(P<0.05),可溶性碳水化合物、乳酸含量和粗灰分显著高于对照组(P<0.05);T_(2)处理的粗蛋白含量显著高于其他处理(P<0.05);T_(2)、T_(3)处理的乙酸和丙酸含量差异不显著(P>0.05);除对照组外各处理的酸性洗涤纤维差异不显著(P<0.05);公鼠和母鼠均对T_(2)处理浸提液饮用量显著高于其余处理(P<0.05),添加T_(2)处理浸提液的小鼠总饮水量显著上升(P<0.05)。【结论】最佳混贮比例为绢蒿和甜叶菊渣质量比为7∶3,含水量64.95%。【Objective】The purpose of this study is to analyze the fermentation quality of different proportions of mixed storage and the drinking water quantity of each treatment extract in mice with Seriphidium Yili and inulins as raw materials with a view to providing a theoretical basis for the full utilization of Seriphidium resources on the northern slope of Tianshan Mountain in Xinjiang.【Method】The silage was fermented for 60 days according to the fresh weight ratio of 10∶0(CK treatment),9∶1(T_(1)treatment),8∶2(T_(2)treatment)and 7∶3(T_(3)treatment)and then the nutritional components,organic acid content,fermentation quality and drinking water data of mice(drinking water quantity and extract consumption)were analyzed.【Results】Compared with the control group,the pH value,ammonia nitrogen/total nitrogen and propionic acid content of silage with different proportions were significantly decreased(P<0.05);with the increase of the proportion of Stevia rebaudiana,the crude fat and neutral detergent fiber of silage with different proportions were significantly lower than those of the control group(P<0.05),and the soluble carbohydrate,lactic acid content and crude ash content of silage with T_(2)treatment were significantly higher than those of the control group(P<0.05).The crude protein content of T_(2)treatment was significantly higher than that of other treatments(P<0.05);the acetic acid and propionic acid content of T_(2)and T_(3)treatment had no significant difference(P>0.05);except for the control group,the acid detergent fiber content of each treatment had no significant difference(P<0.05);the total water consumption of male and female rats with T_(2)treatment was significantly higher than that of other treatments(P<0.05),and the total water consumption of mice with T_(2)treatment was significantly increased(P<0.05).【Conclusion】The best mixed storage ratio is 7∶3 and the water content is 64.95%.
