Phosphorus (P) homeostasis in ruminants has received increased attention over the past decades. Although environmental concerns associated with excessive P excretion in cattle manure have led to incentives to lower dietary P intake, hypophosphatemia-particularly in the periparturient dairy cow-has been associated with conditions, such as the downer cow syndrome or postparturient hemoglobinuria. The objective of this article is to revisit current understanding of P homeostasis in ruminants, to discuss the pathophysiology and clinical presentation of P balance disorders, and to review different treatment approaches to correct imbalances of the body's P equilibrium.
在过去几十年中，反刍动物的磷（P）稳态受到了越来越多的关注。尽管与牛粪便中过量 P 排泄有关的环境问题促使人们降低日粮 P 摄入量，但低血磷症——特别是围产期奶牛——与一些疾病有关，如卧地不起综合征或产后血红蛋白尿。本文的目的是重新审视当前对反刍动物 P 稳态的认识，讨论 P 平衡紊乱的病理生理学和临床表现，并回顾纠正机体 P 平衡失调的不同治疗方法。
