摘要: 为探讨内蒙古青贮饲料品质现状,采用抽样方法对内蒙古青贮饲料质量进行研究。结果表明,内蒙古青贮设备主要以窖贮和壕贮为主,青贮时间一般为9和10月,青贮种类主要有全株玉米青贮、玉米秸青贮、甜菜类青贮等;青贮饲料发酵品质总体表现较好,通过对青贮饲料有机酸进行费氏评分,达到优良等级的占总样品的83%,全株玉米青贮和甜菜类青贮经费氏评分均达到优等,但是,全株玉米青贮饲料中的乳酸含量显著高于甜菜类青贮饲料(P<0.05),乙酸和丁酸含量均显著低于甜菜类青贮饲料(P<0.05),玉米秸青贮饲料费氏评分为良,内蒙古青贮饲料有机酸费氏评定结果与感官评定结果基本相符;3种青贮饲料中,甜菜类青贮饲料的营养品质最好,全株玉米青贮饲料次之,玉米秸青贮饲料最劣。综合分析结果表明,内蒙古全株玉米青贮饲料和甜菜类青贮饲料营养保存率高,发酵效果好,玉米秸青贮饲料质量较差。

Abstract: In order to understand the current situation of silage in Inner Mongolia, on the one hand from Inner Mongolia silage production of hands on the other hand from the silage mass quality determination, on the situation in Inner Mongolia silage for analysis summary. Inner Mongolia silage modulation and storage are able to follow the silage norms, its main storage device to store storage and moat, silage storage time is 9 months, silage species there are whole corn silage, Corn Stover, beet silage, etc. Mongolia silage mass quality overall better, through the production of fine grade rating reached accounted for 83% of the total sample, in three kinds of silage corn stover silage in nutritional quality or fermentation quality were significant (P<0.05).
