摘 要:选择3岁以上,泌乳、日产奶量、胎次、体重相近、体质健康、乳房整齐无病的荷斯坦乳牛20头,采用分期分组对比法试验。试验结果:试验组比对照组日产奶量增加2.19 kg/头,提高10.12%,日标准奶量增加3.2 kg/头,提高18%,在0.05水平上有差异。乳脂率比对照组提高0.39%,在0.05水平上有差异。经济效益分析为:试验组牛日均补饲1 kg/头尿素糖浆饲料舔砖可比对照组多收入3.38元(/头.天),经济效益显著。20 healthy Holstein diary cows of more than 3 years old were chosed in this experiment. Their milking, daily milk yield, birth order, weight were similar. They were divided into test group and control group with 10 cows per group (p〉0.05). Fodder of test group was added with 1 kg molasses--urea reed-blocks per day. Result showed that daily milk yield in test group were 2.19 kg more than that of control group and improved by 10.12 %. Daily milk yield per cattle increased by 3.2 kg and improved by 18 % (P〈0.05). Milk fat rate increased by 0.39 % (P〈0.05) compared with that of control group. Economic benefit analysis showed that test group gained 3.38 yuan more than control group by adding lkg molasses-urea reed-bloc ks per day.
