1 Basal ration furnished liberal Ca, restricted P, typical of those producing aphosphorosis except that beet pulp was substituted for the customary hay
roughage, and animal was kept indoors. Alterations resulted in development of rachitic syndrome rather than uncomplicated aphosphorosis.
2NaH3PO4H2O added to increase P intake to 18 grms. daily 7 days previous to this trial. Animal badly off feed during this trial.
3 Animal received viosterol for 2 months previous to this trial.
