| 摘 要： | 饲粮中添加阴离子盐可以影响奶牛体内的酸碱平衡，预防产乳热的发生。负的阴阳离子差可以增加血液中离子钙浓度，增强钙平衡调节激素的反应。奶牛在产前饲粮中添加阴离子盐可以降低阴阳离子差，减少围产期奶牛亚临床低血钙症的发生，预防产乳热，提高泌乳性能。很多研究结果表明，添加阴离子盐使饲粮阴阳离子差值（mEq／kg）降到0以下，才能达到适宜的酸化效果，但最适宜阴阳离子差的值还需要做进一步的研究。

| Abstract: | Supplementation of anionic salts prepartum can prevent milk fever.The negative cation-anionic difference(DCAD) can increase the concentration of blood-ionized Ca of dairy cow before calving and mitigate responsiveness to Ca homeostatic hormones.Supplementation of anionic salts prepartum can decrease DCAD,reduce the incidence of periparturient hypocalcaemia,prevent milk fever and increase milk production.Many studies indicated that dairy cows would be acidified availably until DCAD decreased below zero.However,research on the optimum range of DCAD needs to be studied further. |
