摘　　要：将玉米秸秆以10、26mm两种不同长度切碎后青贮,分别以直接和全混合日粮(TMR)揉碎两种形式饲喂奶牛进行比较研究。结果表明:两种切碎长度对玉米秸秆青贮质量无明显影响;但无论采用何种饲喂方法,将切碎长度为26mm的青贮玉米秸秆饲喂给奶牛,奶牛产奶量提高,胎衣不下减少,空怀母牛降低,各种疾病发生减少;同时切碎长度增加还可以提高青贮劳动效率。Corn stalk was chopped in two lengths of 10 and 26 mm,and then ensiled.Milk cows were fed with it directly and with total mixture ration(TMR) to carry out a comparative study.The results showed that two kinds of chopping lengths did not obviously affect the quality of corn stalk silage;but when the milk cows were fed with corn stalk silage in a chopping length of 26 mm,no matter whatever feeding method was used,the milk yield of milk cows was increased,the fetal sac was not reduced,open cows were lowered and different diseases were reduced.At the same time,when the chopping length was increased,the efficiency of labor for silage could be improved.
