【摘要】 干玉米秸混菌二次发酵处理后,粗纤维含量下降.用4mol/L盐酸不溶灰法进行肉牛消化试验,测得相近营养水平条件下喂给牛只等量的未处理及发酵处理的玉米秸时,饲粮干物质、有机物及粗纤维的表观消化率在干玉米秸混菌处理后有显著提高(P<0.01).更多还原

【Abstract】 After mix becteria fermentation process of dry maize stalk, the CF(crude fibre)of maize stalk decreased. A beef cattle digestion trial was conducted with HCL-AIA (4N) method. At the similar nutrient level, the beef catties were fed on the diets containing processed or unprocessed maize stalk. The apparent digestibilities of DM (dry matter), organic matter and CF of diet containing fermented maize stalk were improved signif icanty( P < 0 .01).更多还原
