Milk Fever is also known as Hypocalcaemia. It is a disorder mainly of dairy cows close to calving. It is a metabolic disease caused by a low blood calcium level. Between 3% and 10% of cows in dairying districts are affected each year, with much higher percentages occurring on some properties.
Proper dietary management will prevent most cases of milk fever. This generally involves close attention to mineral and fiber levels in the diet prior to calving.
