| 摘 要： | 将玉米秸秆以10、26 mm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26 mm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.

| Abstract: | 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 an... |
