| 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(占日粮精饲料2%),探索其对奶牛产奶量及乳脂率和乳蛋白的影响。结果发现:试验组比对照组产奶量提高0.9千克/天·头(p>0.05),乳蛋白上升,乳脂率下降,但差异均不显著(p>0.05)。

| Abstract: | 14 cows were divided into the control and treatment groups on the basis of parity and expecting calving date.The cows in the treatment group were fed with 2% soybean phosphatide instead of 2% corn in the ration in order to study the effect of soybean phospatide on milk yield and milk fat and protein content.The result showed that the milk yield in the treatment group increased by 0.9kg per cow daily,and milk protein content also increased while milk fat rate decreased,although there was not significant difference(p>0.05). |
