菌酶协同辣椒秸秆微贮对体外瘤胃发酵的影响

Effects of Microbial Silage of Bacterzyme and Pepper Straw on Rumen Fermentation in Vitro

【目的】为评价阿魏酸酯酶微贮的辣椒秸秆产气量及瘤胃发酵参数的变化。【方法】采用体外产气法评价添加阿魏酸酯酶处理的辣椒秸秆的总产气量、可消化有机物含量以及代谢能含量的营养差异。【结果】结果表明,阿魏酸酯酶与复合菌液混合对辣椒秸秆进行发酵,能够提高产气量,且能够维持在正常的pH值范围之内。【结论】添加阿魏酸酯酶,能够提高瘤胃对于氮的利用效率,并促进瘤胃微生物蛋白质的合成。

【Objective】In order to explore the effect of pepper straw microstored by ferulic acid esterase(FAE)on gas production and rumen fermentation.【Methods】The nutritional differences in total gas production,contents of digestible organic matter(DOM)and metabolic energy(ME)were evaluated by in vitro gas production method.【Results】The fermentation of pepper straw by FAE with complex bacteria liquid could increase gas yield and maintain the rumen fluid within the normal pH range.【Conclusion】The addition of FAE can improve the nitrogen utilization efficiency of rumen and promote the synthesis of rumen microbial proteins.
