Doing sow delivery and pig care is a key technology to improve the overall survival rate of the herd. Preparation before childbirth Delivery room and utensil preparation The key issue is disinfection and insulation. The delivery room and the delivery bar must be cleaned and disinfected and sprayed with a 2% aqueous solution of caustic soda. In the soil pigsty, it is necessary to take out the accumulated fertilizer and put on the new soil. It is best to use a blowtorch flame to disinfect. The earth ring can be sterilized with grass and covered with a 20% lime milk powder. In the cold season, there should be heating equipment in the delivery room to ensure that the temperature of the delivery room is not lower than 25 °C, 25 °C ~ 26 °C, and the temperature of the newborn pig incubator should be about 32 °C. Prepare the piglet incubator or cage for the production, put a soft bedding inside, not too long, preferably 10 cm ~ 15 cm. Prepare disinfection drugs such as ear clamps, 5% iodine and 0.1% potassium permanganate, weighing tools, sow record cards, etc. It should be understood that the sows will be transferred to the delivery room 7 days in advance to prevent the sows from producing the pigs to the gestation house. Sow prenatal care 10 days before the birth, gradually change to "speed education", starting from 5 days to 7 days before the gradual reduction of feeding, to 1 day ~ 2 days before delivery to reduce the daily feeding of 1 kg ~ 1.2 kg. At this time, it is best to mix the green fodder and adjust it into a thin diet. Found the symptoms of labor, stop feeding, only feed the bean cake bran soup. If the sow's sensation is not good and the breast expansion is not obvious, do not reduce the material. Also, add some protein-rich prolactin feeds, such as fish meal and chicken powder. Two weeks before the birth, the sows are inspected. If ectoparasites such as cockroaches and scorpions are found, spray disinfection with 2% trichlorfon solution to avoid infection to the piglets. It is not advisable to exercise too much before delivery to prevent deadlocks and miscarriage caused by mutual crowding. Transfer to the delivery room 7 days in advance, familiarize yourself with the environment, facilitate the management of the delivery, and disinfect the sow with 0.1% potassium permanganate solution, especially the breast and vulva, etc., and pay attention to reduce the sow pair Pollution in the production column. Safe delivery Signs of childbirth Three to see a squeeze When looking at the breast, from 15 days to 20 days before delivery, the breast gradually swells from the back, and before the birth, the breast expands and shines, and the nipples on both sides swell outwards. Commonly known as "nipple bombing, it will soon be down." Second, look at the tail root, the vaginal opening is red and swollen, and the sides of the tail root are slightly sunken, but the fatter sows cannot see it. Third, the performance of the sow is uncomfortable, the appetite is diminished, there is mucus flowing out of the vulva, and the grass is made into a nest. The introduction of the variety does not have this kind of performance, just arching the grass together and frequently urinating. It is necessary to give birth within 6 hours to 12 hours after such behavior occurs. One squeeze is a squeezed nipple. Two days to three days before the birth, the nipple can squeeze out the milk. When the current nipple can squeeze out the milk, the delivery time is no more than one day. If the last pair of nipples can also squeeze out the milk, it can be delivered in about 6 hours. Production operation The average time required for normal delivery is about 4 hours, and the average interval between births is 18 minutes. The fewer the number of births, the longer the interval between each birth. The delivery personnel should cut the nails short before washing and wash the arms with soap. The whole process of production should be kept quiet and the action should be accurate and rapid. The average sow will produce the first pig in 30 minutes after breaking the water. When the piglet is produced, immediately use your fingers to pry out the mucus in the mouth, then use soft bedding to wipe the nose and nose and body mucus to prevent clogging, affecting the pig's breathing and reducing the surface water evaporation. Avoid piglets catching a cold. Individual piglets have not broken their placenta after birth, and the delivery personnel should immediately tear the placenta by hand to prevent the pigs from suffocating and dying. Then fix the base of the umbilical cord with your hand, hold the umbilical cord with the other hand, and slowly pull the umbilical cord out of the birth canal. Do not pass the porcine umbilical cord. Knock the umbilical cord in the direction of the piglet and then ligature it 4 cm from the piglet. The section was sterilized with 5% iodine. The umbilical cord that remains on the abdominal wall of the piglet will dry out after three or four days. Immediately after breaking the umbilical cord, place the piglet under the infrared light and bake the body. Then the auxiliary pigs are breast-feeding, and if the pigs are fed too late, the pigs will be "rubbery". Artificial midwifery The sow has a strong pain, the tail is rolled up, the breath is short, the heart beats faster, and the action of giving birth is repeated, but the output of the pig is not seen. At this time, artificial midwifery should be implemented. First massage the sow's breasts, then press the sow's abdomen to help them give birth. Oxytocin can be injected if it is not effective for repeated use for half an hour. The dosage is calculated as 2 ml per 100 kg of body weight, and the child can be born in half an hour. If the injection of oxytocin is still not effective, surgery should be performed, and the sow should be injected with penicillin and streptomycin to prevent infection. The treatment of fake pigs. The fake pig is soft, swollen, and even stops breathing, but the heart is still beating, and the root of the umbilical cord is still beaten with fingers. Rescue method: Use your fingers to quickly remove the mucus from the nose and mouth of the pig, wipe the nose and mouth, and bleed into the nostrils of the piglet; wipe the nose and mouth of the pig with alcohol or liquor to stimulate the recovery. Pour the hind legs of the pigs, encourage the mucus to flow out of the trachea, and pat the pig's chest continuously until the sound is heard; or put the fake pig on the bedding and hold the front and rear limbs Repeated artificial respiration until breathing resumes. After the piglets are all produced, the placenta is discharged about 30 minutes later, and the placenta is also placed on the side. If the discharged placenta finally forms a plug, it means that the placenta has been completely discharged, and the birth is over. It can be judged according to the number of umbilical cords on the placenta whether it is consistent with the number of births. When the sow is extremely tired or the uterus is weak, the hormone can be injected to promote the discharge of the placenta. It should be taken away immediately after discharge to prevent the sow from swallowing, affecting digestion and forming the guilt of eating pigs. The placenta can be washed, added to the kelp or chicken rack soup, and fed to the sow in fractions to promote sow lactation. The contaminated bedding should be cleaned and the sow's breasts, genitals and hindquarters should be cleaned with soapy water or 0.1% potassium permanganate. Half an hour after giving birth, give the sow a moderate amount of warm salt water. It is best to drink warm bean cake bran soup and a small amount of salt to replenish body fluids, relieve fatigue, and avoid sows eating thirsty pigs. After the end of childbirth, the uterus began to contract immediately. On the first day, the genital folds recovered and returned to normal within about one week. Sow postpartum care The sows are not fed in principle within 8 hours after delivery and are only fed to the bean cake bran soup or other thin feed. 2 days to 3 days after delivery should not be fed too much, feed more green feed, until one week later to open feeding The primiparous sows are prone to postpartum loss of appetite or lack of food. It is usually due to too early feeding, too much feeding, too thick feed, or eating gestation, causing indigestion. Insufficient green feed can cause constipation in the sow, loss of appetite, or a decrease in postpartum abdominal pressure, which affects normal digestive function. The sow has no milk or insufficient milk after delivery, and can be fed to millet porridge, soy milk, fetal clothes, small fish, small shrimp soup and other prolactin, or with drug prolactin, 10 tablets of milking spirit, once a dose. Piglet handling The pigs are weighed, the ears are registered and registered, and the canines are cut with scissors to cut the tail.
