摘要/Abstract

摘要：

本试验以老芒麦为原料,通过添加青宝Ⅱ号（FS）、纤维素酶（CE）、蔗糖（S）、玉米粉（CF）和甲酸（FA）等添加剂,研究了调制老芒麦青贮的方法。结果表明：老芒麦直接青贮可调制出优质的青贮饲料。纤维素酶（2.5 g·t^-1）和蔗糖（2%和4%）处理下,乳酸含量和总酸含量显著高于对照（P〈0.05）,且氨态氮占总氮比例显著低于对照（P〈0.05）,可以改善老芒麦青贮饲料的发酵品质;乳酸菌制剂（青宝Ⅱ号2.5 g·t^-1）处理、乳酸菌制剂和纤维素酶的混合（青宝Ⅱ号2.5 g·t^-1＋纤维素酶2.5 g·t^-1）处理未能改善青贮饲料的发酵品质;玉米粉（5%和10%）处理青贮饲料的CP含量与对照差异不显著（P〉0.05）,NDF和ADF含量显著低于对照（P〈0.05）,可改善青贮饲料的营养价值;晾晒1h不能改善老芒麦青贮饲料的品质。

Abstract:

This experiment takes Siberian wildryegrass （Elymus sibiricus L. ） as raw material and studies the method for making Siberian wildryegrass （ Elymus sibiricus L. ） silage by adding FAST-SILE （FS） , cellulose （CF） , sucrose （S）, corn flour（CF） and formic acid （FA）,etc. as additives. The results indicate that high quality silage can directly make Siberian wildryegrass by adding S（2% and 4% ） and CE, the content of lactic acid and total acid in the treatment are markedly higher than CK（ P 〈 0.05 ） , and the content of ammonia-N in total nitrogen is markedly lower than the CK. This reault means these two additives can improve fermentation quality of the Siberian wildrycgrass silage. The treatment of FS （2.5 g·t^-1） and FS ＋ CE（2.5g·t^-1） can not improve the fermentation quality of silage. The treatment of adding CF（5% and 10% ） does not significantly differ（ P 〈 0.05）from the CK. The contents of NDF and ADF are markedly lower than the CK, but it does improve the nutritional composition of the silage. Meanwhile, quality of the silage can not be improved by wilting for one hour.

Key words: Siberian wildryegrass , silage , additives , fermentation quality , nutritional composition
