Results from a clinical study involving 540 cows which recovered after one treatment for hypocalcaemia, 159 cows which recovered after two treatments for hypocalcaemia, and 61 cows which recovered after at least three treatments for hypocalcaemia, showed that the number of treatments before recovery was significantly related to the following factors: Plasma Ca, plasma Mg, packed cell volume, time of first treatment in relation to calving, season of the year, previous milk fever history, management system and the cow's body condition.
