摘要
为评估菌酶复合添加剂对花生秸及花生秸混合青贮饲料发酵效果的影响,以花生秸为原料分别制作花生秸单独青贮饲料(PA),花生秸和玉米芯混合青贮饲料(PC),花生秸和稻壳粉混合青贮饲料(PR),添加菌酶复合添加剂(包含植物乳杆菌、副干酪乳杆菌、纤维素酶、木聚糖酶、葡聚糖酶、果胶酶),以等量蒸馏水为对照组(CK).对不同处理青贮饲料的发酵品质、微生物数量和营养品质进行检测.结果表明,PC具有最低的pH、氨态氮和ADL含量,最高的体外干物质消化率,但是也有一定负面效果,如增加了霉菌和酵母菌数量,降低了粗蛋白含量.菌酶复合添加剂的使用显著提升了乳酸产量,降低了青贮饲料中的pH和氨态氮含量,同时降低了aNDF含量,提升了体外干物质消化率.且PC在菌酶复合添加剂处理下pH降低到4.16.因此,菌酶复合添加剂的使用对于提升花生秸青贮饲料以及花生秸混合青贮饲料发酵品质和营养品质效果显著,具有显著的应用价值.
Abstract
In order to evaluate the effect of microbial enzyme comppsite additives on the fermentation quality of peanut vine and peanut vine mixed silage,this experiment used peanut vine as raw material to prepare peanut vine single silage(PA),peanut vine and corn cob mixed si-lage(PC),and peanut vine and rice husk powder mixed silage(PR).Microbial enzyme comppsite additives(including Lactobacillus planta-rum,Lactobacillus paracasei,cellulase,xylanase,glucanase,pectinase)were added,and a same volume of distilled water was used as the control group(CK).The fermentation quality,microbial quantity and nutritional value of different silage treatments were detected.The results showed that PC had the lowest pH value,ammonia nitrogen and ADL contents,and the highest in vitro dry matter digestibility,but it also had certain negative effects such as increasing the counts of mould and yeast,and reducing crude protein content.The use of microbial enzyme comppsite additives significantly increased lactate production,reduced pH value and ammonia nitrogen content in silage,while reducing aNDF content and improving in vitro dry matter digestibility.And the pH value of PC decreased to 4.16 under the treatment of microbial enzyme comppsite additives.Therefore,the use of microbial enzyme comppsite additives has significant application value in improving the fermentation and nutritional quality of peanut vine silage and peanut vine mixed silage.
