The health status of sows before and after childbirth directly affects the health of piglets afterwards. Therefore, the management of prenatal and postnatal care for sows is a problem that cannot be ignored. The following small series talks to you about some precautions for sows before and after childbirth. First, prenatal Before entering the delivery room, the delivery room should be fully disinfected to reduce the invasion of pathogens and reduce the infection rate. Three to five days before the birth, the sow should be reduced as appropriate. For sows with good sensation and good breast development, they should gradually reduce the amount of feeding, which is reduced by 10%-20% of the daily food intake, reducing one-third or one-half of the late pregnancy. This is beneficial to the sow's rapid development of the piglets after delivery, the sow's stomach is blocked, avoiding vomiting after eating, and it is also conducive to excessive lactation after the sow is delivered, and the piglets will not be able to eat mastitis; Sticky, causing piglets to diarrhea. Childbirth is a strong stress. If the sow does not reduce the amount before delivery, temporary postpartum gastrointestinal dysfunction can cause the feed to stay in the gastrointestinal tract for too long, which will eventually lead to constipation. After constipation occurs, the sow will have low fever and poor appetite. If the sow does not return to normal levels within 3-5 days after delivery, it will inevitably affect breast milk secretion. For the thinner sows, there is no need to reduce the material. If the breasts are not adequately swelled a few days before delivery, some protein-rich prolactin feeds should be fed as appropriate. Second, postpartum When the sow is giving birth, the reproductive organs have undergone drastic changes, and the body's resistance has decreased significantly. Therefore, proper care should be taken after the birth to restore health as soon as possible. Feeding: The sows are very tired and very tired during childbirth, and the body fluids are too much. The sows show fatigue and thirst. Therefore, warm wheat bran water can be given properly for the sows to drink. Sows should not be fed within 8 hours after delivery, after which a small amount of liquid food can be given. The digestive function of the sows after delivery is very weak, and the feeding amount should be gradually restored. If there are more good piglets in the postpartum digestive system, you can return to the pre-feeding amount. If the amount of lactation is small or no milk, you can feed some millet porridge, soup cooked with fish and shrimp, and increase the amount of milk. Or you can use a prolactin, such as: Wang does not leave the film. Management: (1) Post-production disinfection: After the sow has been delivered, it is necessary to remove the pollutants in time and spray disinfectant to create a hygienic and clean environment for the sows. (2) Postpartum anti-inflammatory: After sows are born, postpartum anti-inflammatory care is very important for sows and should be taken seriously. The internal hormone secretion and metabolism of the sows have undergone great changes during birth, and the external reproductive organs have also undergone slight changes. At this time, the body deploys most of the nutrients and defenses to prepare for childbirth, so the external environment and pathogenic microorganisms The resistance has dropped significantly. Therefore, in addition to observing changes in feed intake, mental status, and body temperature after birth, we should also pay attention to whether the sow has intra- and postpartum hemorrhage, postpartum mastitis, sputum, postpartum lactation, especially primiparous sows, if the fetus Feeding too high a nutrient will cause the fetus to be particularly large; or some sows have a particularly large number of litters, some may have dystocia, and the uterus is very susceptible to injury, which in turn causes an inflammatory reaction in the infection. Give the sow uterine inflammation. For the anti-inflammatory of sows, there are currently clinical use of intramuscular injection of cyan, streptomycin, cephalosporins, or uterine betting amoxicillin, metronidazole, iodine preparations, as well as traditional Chinese medicine preparations. Simple injections of antibiotics can have less effective efficacy on inflammatory products of the uterus. Although uterine betting drugs can solve some of the uterine inflammation problems, there are more problems later. Some beating drugs cause perforation of the uterine wall and are forced to be eliminated. First of all, attention should be paid to the prenatal and postnatal care of the sow, including prenatal preparations such as sanitation. Before the sow enters the delivery room, the sow should be cleaned and disinfected, and the bed should be cleaned and disinfected. This practice has obvious control effect on the yellow and white pupa of postpartum piglets in production practice. (3) Sows with long labor period and weak postpartum, which can easily lead to residual fetal clothes in the uterus, and the lochia is endless. For such sows, uterine perfusion can be performed by artificial insemination using traditional Chinese medicine preparations for uterine treatment. Sows that have used artificial midwifery and sows with severe postpartum pus can be perfused with uterine inflammation. After the first infusion of 100 ml, 50 ml is reperfused 48 hours apart. Achieve complete thoroughness. It is worth mentioning that artificial assisted births such as hand rubs, so the damage to sows is particularly large, it is easy to cause endometritis in sows. For the need for artificial sputum production, the head of the delivery room needs to be carefully checked and recorded. Under normal circumstances, natural childbirth. (4) Pay attention to controlling the temperature, humidity and cleanliness of the delivery room. The design of the delivery room should be ventilated, transparent, and cold-proof. Third, the sows prenatal and postnatal related issues What should I do if I don’t have a pig for more than a long period of time? 1. The whole pregnancy of the sow is about 114 days. If it is beyond or 2 days in advance, it is within the normal range. Generally, after the expected date of birth, if it is not enough for 116 days, it can be used to fight cloprostenol. Pig and fetus. If it is more than four days, it is very dangerous. 2, In addition, no pigs, no milk should also consider whether the date is wrong. 3. Add Nongda No. 2 or Boli milk about seven days before birth to shorten the labor process and promote lactation. What if the placenta does not work? 1. Use oxytocin to promote the discharge of the placenta; 2. Let the sow move and promote elimination; 3, use the Palace to better wash the uterus, with green will or hen sensation or excellent health or severe illness Kang for anti-inflammatory. 4, prevention: use the farmer's mother source before the birth of three to five days, qi and nourishing, clearing the palace to eliminate evil, and promote postpartum recovery. How to judge whether the sows are all finished? 1. There is a live piglet with a film of fetus outside, followed by a large piece of fetal clothing, indicating that the sow has been produced. 2. Relatively intact membranes appear on the placenta. Even when bubbles are seen, the sows have been produced. 3, the sow is very comfortable, no longer restless, this time indicates that the sow has been produced; 4, the output of the fetal clothing is very thick, when the color is white, it shows that the sow has been finished. What should I do if my sow does not eat before and after childbirth? 1. Reasons for not eating before giving birth: (1) Infectious disease factors: mild swine fever, Eperythrozoon, Streptococcus, etc. (2) Internal heat: fetal development in the body, dilatation of the uterus, compression of the intestines, resulting in slower bowel movements. (3) Feeding management factors: 1 too much concentrate, lack of green feed, causing constipation in sows, reduced food intake. 2 The amount of feed is too large, resulting in digestive dysfunction and indigestion in the sow. 3 feed mix is ​​unreasonable, feed is single, lack of vitamins, sows due to malnutrition caused by loss of appetite. 4 fed a moldy and deteriorated feed. (4) Drug-induced factors: normal prevention, feeding too much western medicine. 2, the reasons for not eating after childbirth: (1) calving fever (2) Inflammation: birth canal infection, endometritis, mastitis, etc. (3) The postpartum abdominal pressure suddenly decreases, resulting in diminished digestive function. 3. Preventive measures (1) Starting from the gilts, increasing and exempting anti-drugs, protecting the liver and protecting the liver, and eliminating the sub-health of the sows, the method can be solved by using the Agricultural University No. 1 + Blue Ring Sword for 10 days. (1) Give nutrient-rich and digestible feed before delivery. The concentrate, coarse material and green material should be properly matched. It is not suitable for feeding too rich or too thin. The feed can be added with Jialijian or vitality for a long time. (2) Regularly do the disinfection work, especially in the strict disinfection of the pens 7 days before the birth to prevent bacteria from contaminating the vagina. (3) Post-production anti-inflammatory should be done promptly and thoroughly after the end of sow production. This is the introduction of the management techniques for feeding and management of sows before and after childbirth. If the delivery room does not care for the sow, the sow problem will be particularly high. For example, metritis, mastitis, postpartum no milk syndrome, and abnormal estrus after weaning will make people feel overwhelmed, leading to pig farms. The number of non-production days of pigs has increased greatly, and the benefits of pig farms have been greatly reduced.
