Severe lameness in a large proportion of an Angus cattle herd was attributed to phosphorus deficiency. The diagnosis was supported by a rapid response to phosphorus supplementation of the diet. A brief review of the development and diagnosis of phosphorus deficiency is presented. Practical considerations severely limit the choice of a phosphorus supplement. Directions for the use of the supernatant of high-phosphorus fertiliser and water mixtures, as feed or stock water additive and the production of a phosphorus lick are described. Other phosphorus supplements are discussed with particular reference to the fluorine hazard.
安格斯牛群中很大一部分出现严重跛行，原因是磷缺乏。日粮补充磷后迅速恢复，这支持了该诊断。本文简要回顾了磷缺乏的发展与诊断。实际情况严重限制了磷补充剂的选择。文中描述了将高磷肥料与水的混合物的上清液用作饲料或饮水添加剂以及制作磷舔剂的使用方法。还特别提及氟危害，讨论了其他磷补充剂。
