采用30头经产荷斯坦奶牛，按照配对试验设计，研究在围产前期（产前21d）添加自配阴离子盐添加剂对奶牛采食、尿液pH值及产后100d的产奶量、发病率和直接经济效益的影响。试验结果发现，饲喂阴离子盐添加剂日粮奶牛采食量与对照组无显著差异，饲喂4d后可使尿液pH值显著降低，产后100d的产奶量显著提高，发病率显著下降，直接经济效益显著提高。由此表明高产奶牛围产前期饲粮中添加阴离子盐，能够改善奶牛产后的健康状况，提高泌乳性能及经济效益，也表明，自配阴离子盐添加剂饲喂效果确实。

30 Holstein muhiparous cows, according to paired experimental design,were studied the effect of self-developed anionic salt diets fed during the prapartum （prenatal 21 days） on the intake , urine PH value and 100 days postpartum milk yield, disease rate of dairy cows. The results found that the intake of cows fed anionic salt additive dietary has no significant differences from the control group . after being fed 4 days, the urine pH was significantly lower , 100 days postpartum milk yield was significantly increased and the incidence rate decreased significantly, direct economic benefit was improved significantly. It is suggested that adding anionic salt in high dairy cows diets would improve the health status of postpartum cows, improve lactation performance and economic benefits. Theretore , self--developed anion salt does have effect.
