微生物青贮添加剂与尿素对青贮玉米体外消化VFA的影响

微生物青贮添加剂与尿素处理的全株青贮玉米经体外消化处理,测定挥发性脂肪酸总量及乙酸、丙酸、丁酸含量。结果显示:未经任何处理组其挥发性脂肪酸总含量最低,为4.60 mmol/100ml;乙酸、丙酸、丁酸单项含量均低于其它各样;添加微生物青贮添加剂与尿素组的挥发性脂肪酸总含量最高,为7.32mmol/100ml,高于未处理组37.16%,且丁酸含量为1.19mmol/100ml介于只添加尿素组和只添加微生物青贮添加剂组之间;只添加微生物青贮添加剂组丁酸含量为1.13 mmol/100ml;只添加尿素组丁酸含量为1.22 mmol/100ml,为四个处理组中最高。表明添加微生物青贮添加剂与尿素能提高青贮饲料消化后VFA的总含量,降低丁酸的含量。
