摘要/Abstract

摘要： 为探究不同添加剂对紫花苜蓿（Medicago sativa L.）和羊草（Leymus chinensis）混贮品质及维生素含量的影响,本试验以紫花苜蓿+羊草为原料,按6∶4比例混贮。设置对照组（CK组,添加蒸馏水）、植物乳杆菌组（LP组,1×10⁶ cfu·g^-1 FM）、粪肠球菌组（EF组,1×10⁶ cfu·g^-1 FM）、植物乳杆菌+粪肠球菌组（LP+EF组）,共4个组,室温发酵60 d后,测定其营养品质、发酵品质及维生素含量。结果表明：与CK组相比,各添加剂组之间的粗蛋白质（Crude protein,CP）含量无显著变化,乳酸（Lactic acid,LA）含量显著增加（P<0.05）,中性洗涤纤维（Neutral detergent fiber,NDF）和pH值显著降低（P<0.05）；LP组的酸性洗涤纤维（Acid detergent fiber,ADF）、干物质（Dry matter,DM）和可溶性碳水化合物（Water soluble carbohydrate,WSC）含量显著提高（P<0.05）；各处理组中V_K1、V_B2含量均高于CK组。添加植物乳杆菌后的豆禾混贮饲料,V-Score评分（90.38）、感官评定得分（20）、灰色关联度（0.970）,均为最佳。综合分析得出,添加植物乳杆菌可有效改善青贮品质、提高维生素含量,效果最佳。

Abstract: In order to explore the effects of different additives on the mixed silage quality and vitamin content of alfalfa （Medicago sativa L.） and Chinese rye grass/sheep grass （Leymus chinensis）, alfalfa and L. chinensis were mixed at 6∶4. Four groups were set： control group （CK, added distilled water）, Lactobacillus plantarum group （LP,1×10⁶ cfu·g^-1 FM）, Enterococcus faecalis group （EF,1×10⁶ cfu·g^-1 FM） and Lactobacillus plantarum + Enterococcus faecalis group （LP+EF）. After fermentation at room temperature for 60 days, the nutritional quality, fermentation quality and vitamin contents were determined. The results showed that compared with the CK group, the crude protein （CP） content increased, the lactic acid （ LA ） content increased significantly （P<0.05）, and the neutral detergent fiber （NDF） and pH value decreased significantly （P<0.05）.The contents of acid detergent fiber （ADF）, dry matter （DM） and water soluble carbohydrate （WSC） in LP group were significantly increased （P<0.05）, and the contents of V_K1 and V_B2 in each treatment group were higher than those in CK group. After adding Lactobacillus plantarum, the V-Score score （90.38）, sensory evaluation score （20） and grey correlation degree （0.970） were the best. Comprehensive analysis showed that the addition of Lactobacillus plantarum could effectively improve the silage quality and vitamin content, and the effect was the best.
