摘要
选用１５０ 头泌乳荷斯坦牛随机分为三组，采用对比饲养试验方法研究饲喂玉米秸微贮料对奶牛产奶量的效果，结果是饲喂玉米秸秆微贮饲料和去穗玉米青贮组牛的日平均产奶量均比饲喂黄玉米秸组牛有明显提高，分别提高２ ．７ ｋｇ（Ｐ＜ ０ ．０５） 和４ ．０３ ｋｇ（Ｐ＜ ０ ．０１） ；饲喂去穗玉米青贮组牛日平均产奶量比玉米秸秆微贮料组牛日平均产奶量增加１ ．２ ｋｇ（Ｐ＞ ０ ．０５） 。
Holstein lactating dairy cow were randomly divided into the groups of 50 lactating cow in the study.The effect of feeding fermented corn stalk on production of the dairy cow were coducted with the comparative feeding experiements.The result indicated that averag daily milk production of feeding fermented corn stalk and corn silage group were higher 2.7 kg(P<0.05) and 4.03 kg(P<0.01) than that of feeding corn stalk cow,respectively.The averay daily milk production between the fermented corn stalk and the corn silage group were insignificant(P>0.05).
