摘　　要：试验采用不同处理的玉米秸秆对奶牛干物质采食量、营养物质消化率、乳产量以及乳成分的影响进行了综合分析。选取12月龄奶牛30头,分为3组,每组10头,分别饲喂玉米秸秆、青贮玉米秸秆和纤维素分解酶处理后的玉米秸秆。综合来看,以酶处理后的玉米秸秆作为奶牛的粗饲料营养价值最高,其次是青贮玉米秸秆,直接饲喂玉米秸秆的营养价值最低。The experiment compared the influence of different treatment of corn straw on cows dry matter intake, digestibility of various nutrients, milk yield and milk composition. Thirty 12-month-old dairy cows were selected and divided into three groups with 10 in a group. They were fed corn straw, corn straw silage, corn straw treated by fiber-degrading enzyme respectively. On the whole, corn straw treated by fiber-degrading enzyme had highest nutri- tional value as roughage of cows, followed by silage corn straw, direct-fed corn stalks with lowest nutritional value
