milk fever: a disease of milk cows, milk goats and ewes. Technical name hypocalcaemia. In spite of its name, the disease is not a fever, and may affect a dairy cow just before calving or during the seven days which follow calving. The first symptoms are restlessness, moving the hind feet up and down while standing; these symptoms are followed by loss of balance and later loss of consciousness. The disease is common at the third, fourth or fifth time of calving, and is caused by a metabolic disturbance or imbalance in the system, due to a low calcium content in the blood. The disease is treated by injections of calcium borogluconate. Managing and preventing milk fever is crucial for maintaining the health and productivity of dairy animals, ensuring better milk yield and quality.
