玉米秸秆全株青贮与黄贮饲喂效果对比试验

Comparison on the Effects of Feeding with Whole Corn Silage and Yellow Corn Silage on Chinese Holstein

以16头中国荷斯坦奶牛为试验对象,随机分为二组,开展玉米全株青贮与黄贮饲喂奶牛对比试验。两组日粮营养水平基本相同,试验组日饲喂全株玉米青贮、对照组饲喂等量的黄贮玉米。结果表明,试验组头均产奶量较对照组平均每日多产奶3.27kg,效果十分显著,平均每日每头均增加纯收入5.24元,经济效益显著。全株青贮较黄贮能显著提高奶牛产奶量和经济效益。

Sixteen heads of Chinese Holstein were randomly divided into two groups and fed with whole corn silage and yellow corn silage at same nutritional level. Results indicated that milk yield and net income of the group fed with whole corn silage were higher that of the other group for 3.27 kg, and $ 5.24. This demonstrated that whole corn silage was significantly better than yellow corn silage for lactating Holstein.
