Detailed explanation-1: -Milk fever is a metabolic disorder caused by insufficient calcium, commonly occurring around calving. Milk fever, or hypocalcaemia, is when the dairy cow has lowered levels of blood calcium. Milk fever generally occurs within the first 24 hours post-calving, but can still occur two to three days post-calving.

Detailed explanation-2: -It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body’s ability to mobilize calcium. “Fever” is a misnomer, as body temperature during the disease is generally not elevated.

Detailed explanation-3: -A cow with milk fever usually shows very general symptoms of illness which appear when the blood calcium levels are low: she has a lack of appetite, lower body temperature, looks groggy, and has difficulties producing manure and urine (also known as subclinical milk fever).
