1. Dairy farms and large cattle-raising houses have special cow delivery rooms. Dry dairy cows enter the delivery room 15 days before delivery. Healthy cows that normally give birth return to the barn 15 days after delivery. Keepers should perform health checks on cows entering and leaving the delivery room and establish a delivery room file. The delivery room should be kept hygienic and dry, cool in winter and cool in summer, free from typhoon, and the cow's mattress should be clean and dry. 2. For cows with onset symptoms, the on-duty staff should sterilize the cow bed, consignment equipment, the hindquarters and the vulva of the cows, and grazing the grass. For the normal cows that are delivered, the natural delivery of the fetus should be natural, but early Conduct artificial intervention. When the child's limbs are exposed and the genital area is exposed and the amniotic membrane is broken after 0.5 hours, the fetal position and the fetal potential should be checked. If necessary, artificial midwifery should be performed. 3. Immediately drive the cows to stand up after delivery and clean the breasts, hindquarters and oxtails with warm water, remove feces and contaminated grass, and put new grass on it to disinfect the cow bed. 4. Give cows warm salt water after giving birth. 5. Observe the shedding of the cow's placental clothing. If the placenta falls off incompletely or after 10-12 hours of childbirth, the veterinarian should deal with it in time.
