Causes and preventive measures of sow perinatal diseases

What is the sow perinatal period? Feeding management and disease prevention in sows during the perinatal period is very important. This stage is the key to determining whether your sows can bring you high returns! The following small series brings you the prevention and treatment measures for sow perinatal diseases!

What does the sow perinatal period mean?

The sow perinatal period refers to the 7 days before the delivery of the sow to 7 days after delivery. During this time, our main production goal is to make the sow safely deliver, to give birth smoothly, to produce more live pigs, and to promote postpartum lactation in sows. Make piglets healthy and grow fast. It should be noted that this is a short half-month, but the production performance of this half-month will determine the factor that your sow can produce more than 90% of the benefits, so pay attention to the sow's perinatal period and solve its circumference. The importance of the problems that arise during the delivery period is obvious.

Prevention and treatment of sow perinatal diseases

1, constipation

The disease can occur in pigs of any age, with adult pigs and heavy-duty sows prone to develop. The site is usually in the colon. Mainly due to lack of green feed, lack of exercise, excessive conversion of feed, some infectious diseases or fever, chronic gastrointestinal diseases are often induced. Very few people are caused by insufficient drinking water. For the sows, due to the increase of the fetus, the pressure on the rectal wall is increased, the rectal peristalsis is reduced, the stool stays in the rectum for too long, the water is excessively absorbed, and the sow is constipated. Seen in sows with too many litters and too much litter.

Symptoms: decreased appetite, increased desire for drinking water, increased breathing, increased abdominal circumference, restlessness, less stool, dry, hard, spherical, sometimes with mucus. Then often do the defecation posture, no feces are excluded. After a long time, the rectal mucosa is edematous and the anus is prominent. In severe cases, the rectum is filled with a large amount of fecal ball to compress the bladder neck and stop urinating. If there is no complication, the body temperature does not change much.

Control measures: For mild illness, you can use baking soda 10g/head, salt 10g/head, for serious people to apply paraffin oil 100ml/head, or use a lot of warm soapy water deep enema, and massage the abdomen, generally effective. Stop feeding or give a small amount of green fodder and provide plenty of water. For heavy-duty sows, probiotics and multi-dimensional can be added to the feed.

2, postpartum fever

Postpartum fever is more common, which means that the sow has a rising body temperature after delivery and does not eat.

Symptoms: high fever after delivery, increased drinking water, redness of the skin, rapid breathing, lying down, feeding, not eating. Mainly due to inflammation, cold or fetal clothing, fetal clothing is not completely discharged during the labor process, a small amount due to disease, and very caused by heat stroke.

Control measures: First check whether the fetus and the placenta are not completely discharged, and then take the symptomatic treatment. Increased body temperature pigs use Chinese herbal medicine injection to cool the Qing (Kingling, Bupleurum, Shuanghuanglian, etc.), continue high temperature does not retreat, can use aminopyrine fever. Anti-inflammatory uses spectroscopic antibiotics (qing streptomycin plus houttuynia, cephalosporins, long-acting oxytetracycline, etc.). In severe cases, you can use a small amount of water to pour the head of the pig body, increase the amount of water after adaptation, or directly use alcohol to pour the head of the pig. Heatstroke pigs use only the ear vein to bleed. After the body temperature drops, it can supplement the composite vitamin B, vitamin C, and green fodder to promote appetite recovery. In the summer, it is necessary to strengthen the heatstroke prevention and cooling work of the birthing house.

3, do not eat after delivery

Refers to the sow not eating or giving a sharp drop in appetite after giving birth.

(2) intramuscular injection of penicillin 50,000 IU / Kg + streptomycin 30,000 IU / Kg, 2 times a day, for three days, fever symptoms can be used to clear the treatment with Qingkailing, Bupleurum and so on.

5, the placenta does not

Also known as the retention of the placenta, it means that after the sow is delivered, the placenta (fetal membrane) is not discharged within 24 hours.

Abortion, premature delivery, postpartum or endometritis, placental inflammation, improper management, lack of exercise, and maternal body can also occur.

Prevention:

(1) Injection of pituitary or oxytocin 20 to 40 IU. It is also possible to intravenously inject 20 mL of 10% calcium chloride or 50-100 ml of 10% calcium gluconate.

(2) When the treatment is invalid, the hand can be pulled into the uterus to peel off and pull out the placenta. It is difficult to peel off the pig's placenta. The uterus was washed with a 0.1% potassium permanganate solution, and after the washing solution was derived, an appropriate amount of antibiotic (1 g of oxytetracycline plus 100 mL of distilled water was dissolved and injected into the uterus).

(3) midwifery, while using intravenous drip, the first bottle: 5% glucose normal saline 500ml + penicillin 5 million IU + streptomycin 4 million IU, the second bottle: normal saline 250ml + complex vitamin B20ml + houttuynia 20ml.

(4) Strengthening feeding management, proper exercise, and feeding of calcium and vitamin-rich feed can effectively prevent pigs' fetal clothes.

6, the whole nest stillbirth or mummies

Intramuscular injection of oxytocin 4ml promotes the discharge of stillbirth and mummies, after all the fetuses are discharged

Intravenous infusion: the first bottle: 5% glucose normal saline 500ml + penicillin 5 million IU + streptomycin 4 million IU,

The second bottle: physiological saline 250ml + composite vitamin B20ml + Houttuynia 20ml. The blood of the sows and the heart of the dead pigs are diagnosed in the laboratory, and the corresponding vaccine work is done according to the test results.

7, dystocia

If there is amniotic fluid discharge and strong blame for 1~2 hours, there is still no piglet output or the litter interval is more than 1 hour, which means it is difficult to produce and needs artificial midwifery.

Prevention:

(1) The sow with a history of dystocia is intramuscularly charged with placenta or cloprostenol 1 day before delivery.

(2) If the uterus contraction is weak or the litter interval is too long, the following methods can be used to assist the childbirth:

a) Press the abdomen from front to back with your hand, or slam the sow in the lying direction.

b) Rehydration of sows that consume too much sows can help with childbirth.

c) Injecting oxytocin 20~40IU, it should be noted that there is a piglet output before it can be used.

d) If the above methods are ineffective or due to fetal oversize, fetal position is not correct, pelvic stenosis and other causes of dystocia, artificial assisted labor should be taken immediately.

(3) artificial midwifery: first hit 2ml of cloprostenol, cut the nail and smooth the periphery, disinfect with 0.1% KMnO4 disinfectant, lubricate the hands and arms with paraffin oil, and then slowly extend into the uterus contraction rhythm In the vagina, when the uterus is dilated, grasp the piglet's lower jaw or hind leg and slowly pull it out. After the birth, the uterus should be washed 2~3 times, and the antibiotics should be injected for 3 days to prevent metritis and vaginitis. occur.
