Postpartum nursing measures for sows

During the delivery of sows, the reproductive organs changed sharply, and the resistance of the body decreased significantly. Therefore, sows should be given proper care after delivery so that they can return to health as soon as possible and put into normal production. Sows should observe food intake and body temperature changes at any time after delivery, and pay attention to massive hemorrhage, postpartum mastitis, paralysis, postpartum lack of milk and so on. The birth canal of artificial midwifery sows should be cleaned and drugs should be taken to reduce inflammation. Gradually increase the feed 2-5 days after delivery, reach the highest dosage after 1 week, and give as much as you can. 2-3 days before weaning, diet should be reduced according to the fat condition of sows, and drinking water should be controlled.

Check the placenta.

Check whether the placenta is completely excreted, and whether the number of placenta or umbilical cord is consistent with the litter size. If the placenta does not fall, 10 mg diethylstilbestrol is injected intramuscularly. After cervical dilatation, oxytocin 30 international units can be injected intramuscularly every 30 minutes for 2 or 3 consecutive times. After confirming that the placenta was completely excreted, 80 ~ 1.6 million international units of penicillin were injected into the deep part of the birth canal.

Adopt appropriate anti-inflammatory methods

Parturient sows or fetuses are too large or too many, dystocia sows are prone to uterine damage, anti-inflammation for 7 days as a course of treatment, each dose of penicillin per kg body weight intramuscular injection of 30,000 units, twice a day. At the same time, 0.1% potassium permanganate solution at a temperature of 0.1% can be injected into the birth canal until it returns to normal. For sows with a history of postpartum illness, the medicine is also given according to the above method. For normal parturient sows, each dose of penicillin per kilogram of body weight was 20,000 units, twice a day for 20 days.

After anti-inflammatory sows, there is still pus discharge treatment after 1 week: first, the uterus is infused with lukewarm 0.1% potassium permanganate solution 200kg 300ml, while intramuscular injection of diethylstilbestrol 5 mg to dilate the cervix; about 30 minutes of intramuscular injection of oxytocin 30 international units, once every 30 minutes, twice in a row. At the same time, the mixture of green and streptomycin was injected intramuscularly, combined with dexamethasone phosphate injection. The mixture of 10% glucose saline + penicillin 80 ~ 1.6 million units can also be put into the deep part of the birth canal, once a day for 3 consecutive days, with excellent results.

For sow postpartum anti-inflammation, removing blood stasis and removing stagnation, the placenta can also be fed with Chinese herbal medicine. Boil the fresh motherwort 0.25kg + water 1000 ml to 300kg 400ml, add 0.2kg brown sugar after cooling, mix and feed it in the morning and evening for 3 consecutive days, the effect is better.

Feeding aspect

During childbirth, there is a lot of physical exertion and a lot of body fluid loss, and the sows show fatigue and thirst, so prepare enough, warm 1% salt water for the sows to drink. Sows should not be fed within 8 hours after parturition, warm water should be supplied, and liquid food should be given in the morning the next day, because the digestive function of postpartum sows is very weak, so the feeding quantity should be restored gradually. If the digestive ability of sows recovers well, there are more piglets, and the amount of feed can be restored to the amount before delivery after 2 days. If the sow is short of milk or no milk, measures must be taken immediately to save the piglets. You can first prepare some porridge feed that promotes milk, such as Millet Congee, soup made with small fish and shrimp, soy milk, milk, etc., and feed them three times a day. After the milk production comes up, it gradually decreases until the feeding is stopped. If it still doesn't work, you can use medicine to promote lactation. Prolactin: 40 grams of Wang Buliuxing, 30 grams of Aristolochia mandshurica, 50 grams of motherwort, 40 grams of Liushenqu, 30 grams of Jingsan, 20 grams of Paeonia lactiflora, 50 grams of fried malt, 30 grams of du safflower, 8 herbs mixed with boiled juice, one dose a day, twice a day for 2 consecutive days.

Management aspect

After the sows give birth, the contaminants should be removed in time. After the walls, floors and railings are cleaned, 2% Laisuer is sprayed for disinfection, so as to create a hygienic, quiet and fresh air environment for the sows. Carefully observe the dynamics of sows and piglets after delivery. There are varying degrees of damage to the uterus and birth canal of sows after delivery, and the pathogenic microorganisms are easy to invade and reproduce, which brings harm to the body. For common diseases such as uterine inflammation, postpartum fever, mastitis, piglet dysentery and other diseases should be detected and treated as early as possible, so as not to infect the whole litter of piglets. For example, if a sow is found to be in low spirits, loss of appetite, leftovers and other phenomena, it is necessary to find out the cause in time. If it is caused by uterine inflammation, it can be cured after continuous injection of penicillin for 2 days, which generally will not affect the lactation of piglets. If piglets are found to have diarrhea, the source of infection should be cleared immediately and treated in time. After 3 days of delivery, sows can be put into the playground for free activities, so that they can come into contact with the sun, restore physical strength and promote digestion, which is very beneficial to improve milk production. But the activity time should not be too long to prevent cold and shock. In the investigation of sow production in this county, the author found that the majority of professional sow farmers in rural areas do not pay attention to hygienic measures for postpartum sows, which can easily cause many common obstetrical diseases in sows, such as postpartum hysteritis, mastitis, no milk syndrome, postpartum fever, tetanus, postpartum fasting and so on, so as to affect reproductive function and even be eliminated. Paying attention to the postpartum hygiene of sows can greatly reduce the occurrence of many postpartum diseases.
