摘要 将24头处于泌乳稳定期的荷斯坦奶牛分成4组,对照组A组、试验B组、C组、D组各6头。对照组粗饲料为干玉米秸,试验各组用青贮、苜蓿干草、青贮+苜蓿干草替代部分干玉米秸,同时在添加苜蓿干草组相应减少精饲料的饲喂量,随机用不同搭配的粗饲料进行对比试验。经统计分析,添加青贮组比干玉米秸组产奶量,乳脂肪,乳蛋白分别提高4.83%、1.55%、1.06%,差异不显著(P>0.05);添加苜蓿干草组比玉米秸组产奶量,乳脂肪,乳蛋白质分别提高9.00%、4.04%、3.18%,差异显著(P<0.05);添加青贮+苜蓿干草组比玉米秸组产奶量,乳脂肪,乳蛋白质分别提高13.00%、5.59%、4.24%,差异显著(P<0.05);此外各试验组奶牛的增重比对照组明显。
