小苏打对奶牛泌乳性能的影响试验

Effect of Sodium Bicarbonate on the Milk Performance of Lactating Dairy Cows

试验选择处于产奶高峰期的奶牛20头,随机分成两组,每组10头。试验用奶牛补充精料配方参照NRC、SB/T10261-96标准设计,试验组奶牛补充精料中添加0.8%缓冲剂小苏打。试验结果表明,试验组奶牛乳脂率和产奶量分别提高1.98%和11.21%(p<0.05),单位产奶成本降低5.88%。

dairy cattle at top milk production were selected and random allotted into experimental group and control group. They were both fed with the same diet and supplement feed but the experimental group was added with 0.8% sodium bicarbonate. The result shows that milkfat percentage and milk yield of the cows in experimental group increased 1.98% and 11.21%(p<0.05) respectively and the cost of supplement feed per kilogram milk yield reduced 5.88%.
