This paper presents parturient paresis ("milk fever") aetiopathogenesis and describes the synergic role of magnesium in regulating the hormonal system of calcium metabolism in relation to its adjunct effect in preventing the development of the disease in dairy cattle. It also presents theoretical, experimental and clinical evidence for a link between the occurrence of subclinical hypomagnesaemia and the incidence of parturient paresis. It has been shown that magnesium deficiency reduces the ability of cows to mobilise calcium in response to hypocalcaemia. The links between the biochemical properties of magnesium and the aetiopathogenesis of parturient paresis in dairy cows are explored and their consequences for the prevention of this disease are considered.
