中草药饲料添加剂对奶牛产奶量及牛奶品质影响初探

Preliminary Analysis of the Influence of Feed Additive of China Herbal on Cow Milk Yield and Quality

试验选用黄芪、王不流行等15味中草药添加剂,研究其对奶牛产奶量及牛奶品质的影响。结果显示:在不同泌乳时期,添加中草药使得不同泌乳期奶牛产奶量都有所提高,泌乳初期、泌乳盛期和泌乳中期各试验组的日均泌乳量均比其相应对照组日均泌乳量提高12.2%、24.5%和3.4%。对试验牛及其牛奶理化指标测试结果显示:饲喂中草药添加剂后各泌乳期乳脂含量和游离脂肪酸含量降低、蛋白质含量和非脂类干物质含量提高,但变化不大,其物理指标也没有大的波动。由此可见,饲喂中草药添加剂后奶牛的理化指标均正常,既保证了奶牛的健康又保证了牛奶的安全性、无污染性和天然性。
