摘　　要：日粮中的阴、阳离子对奶牛的正常生产和健康有着重要的意义,它们不仅影响奶牛体液的酸碱平衡和渗透压、机体的代谢活动及多项生理指标,而且在奶牛不同的生理阶段,适宜的日粮阴阳离子平衡能提高奶牛的采食量、生产性能,还能有效预防奶牛的产后瘫痪等疾病。作者现就日粮阴阳离子平衡(dietary cation-anion balance,DCAB)在奶牛上的应用进行综述,为生产实践中合理应用提供一定的理论基础。Supplement with anions and cations had significant effect on normal production and dairy cow health. It not only affect many physiological indicators, including body fluid acid-base balance and osmotic pressure, body of the metabolic activities, but also increase the feed intake and milk production on the condition of appropriate addition of acid-base. In addition, it was effective in preventing postpartum dairy cattle diseases such as paralysis. The author summaries the application of DCAB on the dairy cow production and provides a theoretical basis for rational application on production practice.
