| 摘 要： | 本试验选择16头处于干奶期的健康荷斯坦奶牛,各试验牛体重、年龄、胎次相近,随机分成4组,每组4头。试验分为两期,一期饲喂基础日粮,二期以苜蓿、羊草、全株玉米青贮和干玉米秸秆各粗饲料替代30%基础日粮。考察不同粗饲料对奶牛能量代谢的影响。试验结果表明苜蓿的饲草相对饲用价值(RFV)值最高,一定程度上说明了苜蓿的营养价值最高,玉米青贮较玉米秸秆饲草相对饲用价值(RFV)值高,说明青贮改善了玉米秸秆的品质,提高其营养价值。

| Abstract: | The test choiced sixteen healthy holstein cow in dry milk.The test cow had randomly divided into four groups on weight,age and closey parity.One test had four cow.The test is divided into two phase that the first phase had feed basal diet and the second phase had feed roughage,such as chinensis,alfalfa,corn silage and dry corn straw,replacing 30% of base of diet for inspecting the influence of energy metabolism on cow in different roughage.The test results showed that alfalfa had the highest value(RFV)and the corn silage had higher value(RFV)than corn straw.It means silage had impoved the quality and nutritional value of Corn Straw. |
