When the cows enter the delivery room two weeks before delivery, health checks should be performed on the cows entering and leaving the delivery room. The delivery room must be dry and sanitary, and at the same time, the perinatal care must be strengthened. Before the cows give birth, they should clean their hindquarters and vulva with 2% - 3% of Lysol. For normal delivery cows, no artificial midwifery should be implemented. In case of difficult labor, the veterinarian should deal with it in time.

When the fetus is exposed, the amniotic membrane can be torn to take the amniotic fluid, but the water should not be broken prematurely. The fetus can usually be delivered normally 30 minutes after the water is broken. After exposing the vulva to the fetal head, use a sterilized towel to remove the mucus from the mouth and nose. The umbilical cord is not disconnected. The movable fetus is naturally disconnected. After the disconnection, the contents are squeezed out by hand, the umbilical cord sheath is sterilized with iodine, and the contaminated bedding is promptly removed.

Two weeks after delivery, examinations such as ketouria should be performed. If there is no disease and normal appetite, transfer to large groups can be managed.
