Postpartum paralysis. Acute hypocalcemia, also known as milk fever, which occurs after delivery in dairy cows, is a common and frequently occurring disease. The disease mostly occurs in 5-9-year-old high-yield dairy cows, which is characterized by depressed spirit, loss of appetite, tremor of limb muscles, unstable standing, paralysis and inability to lie on the ground. In severe cases, the sensation was lost, the body temperature dropped below 36 degrees, and the head and neck bent toward one group in an "S" shape.
