The Treatment and prophylaxis of bovine parturient paresis (milk fever)

Abstract

In normal, non-pregnant dairy cows i/v injection of calcium hypophosphite raised the serum level of calcium, but scarcely affected the level of phosphorus. The administration of calcium borogluconate resulted in only slight changes in serum phosphorus, but a dose-related increase in phosphorus occurred after injection of calcium glycerophosphate. The usefulness of such an increase in phosphorus in paretic cows is questionable. In most clinical cases of parturient paresis studied, calcium administration by any route is effective. The prophylactic use of i/v injections of 1 alpha -hydroxycholecalciferol at 72 hour intervals before expected parturition is very effective.
