| 摘 要： | 本实验选用14头年龄、胎次、产奶量、乳成分基本一致的奶牛,分为对照组和试验组。试验组奶牛日粮用未经包被处理的大豆磷脂替代玉米(占日粮2%),预饲10天后,测定此后48天内每天每头的产奶量,并定期检测乳脂率,乳蛋白。结果发现:试验组比对照组产奶量增加0.9kg/天.头,乳脂率及乳蛋白上下变化不大,统计检验差异均不显著(P>0.05)。

| Abstract: | Fourteen Holstein cows with similar age and close parturition date were assigned to two groups in the experiment. The cows were fed with 2% phospholipid in the ration for the experimental group and instead, 2% corn of the ration for the control group. The milk yield and fat and protein contents were tested during 48 days after 10 days pre-treatment. The results showed that the milk yield of the experimental group is 0.9kg/d higher than the control group, and the total milk fat and milk protein contents were few changed up or down, but non of them has significant difference statistically (P>0.05). |
