ABSTRACT

MILK FEVER (HYPOCALCAEMIA, PARTURIENT PARESIS, ECLAMPSIA) DEFINITION/OVERVIEW The average annual incidence of milk fever in dairy herds is approximately 5% (575), but individual farms may have a prevalence of 60-70% when calving at pasture. Milk fever can also occur in older beef cows (more than fourth calvers), especially dairy crosses (e.g Hereford ×Holstein), again more common in autumn-calving cows.
