Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, usually of dairy cows, characterized by reduced blood calcium levels (see: Hypocalcemia). It is most common in the first few days of lactation, when demand for calcium for milk production exceeds the body’s ability to mobilize calcium reserves. “Fever” is a misnomer, as body temperature during the disease is usually below normal. Low blood calcium levels interfere with muscle function throughout the body, causing general weakness, loss of appetite, and eventually heart failure.[1] Hypocalcemia is more common in older animals (which have reduced ability to mobilize calcium from bone) and in certain breeds (such as Jersey cattle). Hypocalcemia, like milk fever, occurs occasionally at any time during the lactation or pregnancy and in many mammalian species.

If the cow succeeds in rising, she staggers, and will very soon fall. The cow’s appetite can be maintained at that stage. Body temperatures are from 37 to 38.5 °C (normal range 38-38.5 °C).[2][verification needed] This stage, referred to as “first degree”, corresponds to calcemiae of 55 to 75 mg/l. In typical cases, the cow’s head is in a so-called “self-auscultation” position. Mydriasis is often present. The heart can be slow or arrhythmic. The body temperature is 35 to 37 °C. In that stage, referred to as “second degree”, calcium levels in the blood are of 30 to 65 mg/l. In advanced cases, the cow is lying on its side, seeming dead. The body temperature can go as low as 32 °C. This is the third degree, with calcemia as low as 20 mg/l. Treatment[edit]
