饲喂全株玉米青贮与玉米秸秆青贮日粮对奶牛养殖效益的影响对比

Influence of Feeding Benefit Whole-plant Corn Silage and Corn Straw Silage on Cow′s

本试验通过给奶牛饲喂全株玉米青贮与玉米秸秆青贮日粮,观察比较两者对奶牛产奶量和奶品质的影响。结果显示:饲喂全株玉米青贮日粮的奶牛,在少喂1 kg混合精料的基础上,产奶量比饲喂玉米秸秆青贮日粮的奶牛的产奶量明显提高;采用蜡熟期玉米制作全株青贮比收获籽实后制作秸秆青贮饲喂奶牛的经济效益高。

In this study, the daily diet comprising whole-plant corn silage and corn straw silage were fed to cows, then compared their effect on milk production and quality. The results showed that the cows eating the whole-plant corn silage produced higher milk yield, compared with the group of eating corn straw silage even if they were less given 1 kg mixed concentrate feed. Silage made of whole-plant corn at the ripening stage brought higher economic
