Hypocalcemia and hypophosphatemia are relatively common in periparturient cows. This article reviews the etiologic factors that contribute to the development of these conditions. The physiologic role of magnesium in calcium homeostasis and the physiologic effect of dietary cation-anion difference at the cellular level are discussed in depth. A theory to explain the development of periparturient hypophosphatemia is developed.
低钙血症和低磷血症在围产期奶牛中相对常见。本文综述了导致这些病症发生的病因。深入讨论了镁在钙稳态中的生理作用以及日粮阴阳离子差在细胞水平的生理效应。并提出了一种解释围产期低磷血症发生的理论。
