Key points for attention in sow delivery

The delivery of Wu Fengjun sows is one of the most important links in pig management, and every little life begins to grow from here. If it does not grow well in the delivery room, it will have a great impact on the future growth and development. Therefore, in all aspects of pig breeding, we should pay special attention to the management of the delivery room and do a good job of sow delivery and newborn piglets. 1 preparation of the delivery room: 5-7 days before entering the delivery room, the sow will clean the delivery room and thoroughly disinfect it with 2% caustic soda water. Disinfect again with disinfectant before use, dry and set aside. The temperature of delivery room is generally 15 ℃ ~ 18 ℃. Clean bedding grass can be put in cold winter and spring, and appropriate measures can be taken to lower the temperature in summer. (2) the sow was transferred to the delivery house 5-7 days after the expected delivery date, and was familiar with the environment of the delivery house, and gradually reduced the amount of feeding from now on, and stopped feeding on the day of delivery to prevent sows from overeating, dystocia, excessive milk, constipation, mastitis and suckling pig indigestion. There is no need to cut down on those who feel bad about the fat. (3) from the due date to delivery, a special person is on duty, waiting around the clock. Once it is found that sows are restless, less appetite, more stool times and less feces, milking nipples have milk outflow, breast fever, separate and straight in the shape of "eight", hit the door or trough with the head, accompanied by labor pains or increased frequency of labor and other symptoms, that is, they should be prepared for midwifery. There must be a special person to deliver the baby, do not leave, want people to wait for pigs, not pigs and other people. Especially in the cold season or at night, we should be more vigilant, must not be negligent, so as not to cause unnecessary losses. Keep quiet in the delivery room, no loud whining or loud noise, so as not to frighten the sows. Do not beat pigs under any circumstances, especially the first-born sows, you should wait patiently for the delivery of milk. 5 wash the breasts and genitals of sows prenatal, and then scrub and disinfect them with 0.1% potassium permanganate water to prevent infection. Squeeze out the contaminated milk in the nipple and discard it to avoid sows suffering from uterine inflammation or piglet dysentery. And prepare utensils and medicine, all appliances should be disinfected. 6 after the piglet is born, first use the birth cloth to dry the oral and nasal mucus and dry the fur to ensure that the piglets breathe smoothly. And then process the umbilical cord. When the umbilical cord is broken, the blood in the umbilical cord is dragged back into the piglet, then it is wrenched 3-5cm away from the piglet's abdomen and disinfected with iodine. 7 in case of false dead piglets (not breathing, but the heart and umbilical cord are still beating) should be rescued immediately, lift the hind legs upside down, pat the back or put four hooves up, one hand on the shoulder, the other on the buttocks, flexion and extension repeatedly until the piglets make a sound. 8 in the process of giving birth, sows should be kept quiet. Piglets should eat enough colostrum immediately after birth, and then put it in an incubator (the temperature in the box is 30 ℃ ~ 32 ℃). Especially in the cold winter, you should eat colostrum as soon as possible, otherwise your body temperature will drop and die soon. Pay special attention to the number of placentas excreted. Generally speaking, each piglet has one placenta. But there are also two piglets or more piglets with one placenta, so the number of umbilical cords should be counted carefully. If there is a small number of umbilical cords in the placenta. There may be unborn piglets or placenta retention may occur, measures should be taken to deal with it in time. After the sow gives birth, the placenta should be removed immediately and the site should be cleaned up. After all piglets are born, ear number, weighing, tooth cutting, tail amputation, injection of hemogenin (iron deficiency anemia and leukomyopathy) should be made immediately, and the birth record should be made. For sows with a first birth or a history of dystocia. In order to promote smooth delivery. Can be appropriate intramuscular injection of oxytocin (the application of this drug must pay attention to, such as the sow's cervix is not open, do not apply oxytocin). The dose for each use is 1050 units, and add it again 30 minutes later if necessary, and no piglets are delivered after another 10 minutes. The birth canal should be checked immediately for abnormalities. Prevent several piglets from blocking the cervix or abnormal fetal position of piglets at the same time, resulting in dystocia. 12 dystocia treatment: in case of dystocia, routine midwifery is required, and disinfectant is used to wash the buttocks and vulva of sows. The operator sterilized his arms and applied oil. The midwifery operation should be light and stable. After delivery, the sows were washed with 0.1% potassium permanganate to rinse the uterus twice a day for 7 days and infused with antibiotic saline. The same treatment is done for sows that give birth to stillbirths and mummies to prevent uterine inflammation. Excerpt from Animal Husbandry and Veterinary Today.-2009, (8).-31 mi-good article.
