Sows giving birth is one of the most important aspects of pig management. Every little life starts from here. If it grows poorly in the delivery room, it will have a great impact on future growth and development. In all aspects of the work, special attention must be paid to the management of the delivery room, and all work should be done for the sows and newborn piglets.

1. Delivery room preparation: The sow should clean the delivery room 5-7 days before entering the maternity room, completely disinfect it with 2% fire alkali water, and empty the circle. Disinfect again with a disinfectant before use and dry it for later use. The temperature of the delivery room is generally 15-18 degrees. It is advisable to put clean bedding in cold winters and springs. In summer, appropriate measures can be taken to reduce the temperature.

2. The sows are transferred to the farrowing house 5-7 days before the expected date of birth. They are familiar with the environment of the farrowing house, and gradually reduce the amount of feeding from this time. The sows will stop feeding on the same day to prevent the sows from overfeeding, excessive milk production, and constipation. Knots, mastitis, suckling indigestion, etc. There is no need to cut down on the bad news.

3, the expected date of delivery to the time of delivery by a person on duty, stay up all night. Once the sow is found to be uncomfortable, her appetite is reduced, her bowel movements increase, her stool volume is low, milk is pumped out of her nipples, her breasts are hot, her body is separated and straightened, and her head hits the gate or trough. There are symptoms such as increased frequency of pain or labor pains, that is, preparations for confinement and midwifery should be made. There must be a special person to deliver a child, do not leave it, ask people to wait for a pig, not a pig. Especially in the cold season or at night, it is necessary to increase vigilance. Never neglect your negligence so as to avoid unnecessary losses.

4, to keep quiet in the delivery room, barking loud or loud noise, so as not to scare the sow. In any case, do not fight pigs, especially the first-born sows, but also have to wait patiently for delivery.

5, prenatal production of sows, genitals washed, and then rubbed with 0.1% potassium permanganate water to prevent infection. Contaminated stored milk in the nipple was discarded and discarded to prevent the sow from having metritis or piglet diarrhoea. And prepare tools and medicines, such as birth records form, towels, scissors, 5% iodine and other drugs, soap, ligature, weighing and breaking pliers, teeth removal pliers, ear number pliers, etc., all appliances should be disinfected.

6. After the piglets are born, dry the oral mucus with a cloth and dry the fur to ensure that the piglets breathe freely. Then treat the umbilical cord. When the umbilicus is broken, the blood in the umbilical cord is first plucked back into the piglet body, and then the umbilical cord is disinfected by breaking it at 3-5 cm from the abdomen of the piglet.

7. In the event of a false-dead piglet (not breathing, but the heart and umbilical cord are still beating), rescue immediately, lift the hind leg backwards, tap the back, or turn its four hoof upwards, hold one shoulder in one hand, butt the other, bend and stretch repeatedly until the piglet Make a sound.

8. During the farrowing process, the sow should be kept quiet. After the birth of the piglet, the colostrum should be eaten immediately and put into the incubator (the temperature inside the box is 30-32C). Especially in the cold winter, colostrum should be eaten as soon as possible, otherwise it will soon die if the body temperature drops.

9, pay special attention to the number of discharge of the tires, in general, each piglet a tire clothing. However, there are also cases where 2 piglets or piglets have a birth suit. The number of umbilical cords should be carefully counted. If the number of umbilical cords discharged from the placenta is small, it is likely that there are still unborn piglets or it may happen that the placenta is detained. Take measures to deal with it in time. After the sow is completed, the placenta should be removed immediately and cleaned up.

10. After all the piglets are born, they should immediately play the ear number, weigh, cut teeth, sever the tail, and inject iron selenium blood serum (put iron-deficiency anemia and white muscle disease), and make a litter record.

11, for the first production or have a difficult birth record sows, in order to promote smooth delivery, may be appropriate to intramuscular injection of oxytocin (practical this drug must pay attention, such as the sow cervical mouth is not open, do not use oxytocin) . Use a dose of 10-50 units at a time. If necessary, wait for 30 minutes before adding a second one. Wait for 10 minutes before seeing the piglet still open. Check for abnormalities in the birth canal immediately to prevent several piglets from blocking the cervix at the same time. There is a malformation of piglets, which leads to dystocia.

12. Difficulties in handling: In case of difficult production, the midwife and genital area must be washed according to conventional midwifery and disinfectant. The surgeon disinfected both arms and applied lubricating oil. Midwifery operations should be lightly stabilized. After production, the sow should be washed with 0.1% potassium permanganate twice daily for 7 days and infuse antibiotics with normal saline. For sows that produce stillbirths and mummies, the same treatment is done to prevent metritis from occurring.
