摘 要：
为了探讨盐藻粉对奶牛产奶性能免疫机能的影响,试验选择处于泌乳中期的健康荷斯坦奶牛18头分为对照组、1.5倍维生素A(165IU/kg)组和盐藻粉组进行饲喂试验。结果表明:日粮中添加盐藻粉或1.5倍维生素A对奶牛的产奶性能有一定促进效果,盐藻粉组优于1.5倍维生素A组;添加盐藻粉可显著降低乳中体细胞数,血清IgG抗体和IgM抗体浓度也有明显增加的趋势;添加1.5倍维生素A也可显著降低乳中体细胞数,血清IgG抗体浓度有明显升高的趋势。

摘 要：
The present study was conducted to discuss the effects of dunaliella salina powder(DSP) on milk performance and immune function.18 healthy Holstein cows in mid lactation were randomly blocked into three groups(control group,1.5 times of vitamin A group,DSP group).The results showed that the addition of DSP or 1.5 times of vitamin A in diet of the dairy cows could improve the milk performance and that DSP group was better than 1.5 times of vitamin A group.The milk somatic cell counts were significantly decreased for the DSP group,and the concentrations of IgG and IgM in serum also had a significantly increasing tendency.The addition of the 1.5 times of vitamin A could significantly decrease the milk somatic cell counts,and the serum IgG content had a significantly increasing tendency.
