The sow is difficult to give birth for 2 days, what if you can't take it out? Common treatment methods

Stillborn fetus: sows with continuous lochia and symptoms of delivery can connect the vas deferens with syringes and inject saline with a concentration of 1% Mel 3% and a temperature of 36-38 ℃ into the uterine cavity of the sows, until the salt water flows out of the sows, combined with oxytocin. Live fetus: intramuscular injection of Chloroprostol Sodium 0.1-0.2mg. After confirming the birth of the first fetus, 30-50 international units of oxytocin can be injected intramuscularly or subcutaneously.

1. Common treatment methods of dystocia in sows

1. The method of stillbirth

(1) for a small number of sows that are close to or longer than the period of delivery, and there is continuous lochia in the body, showing symptoms of delivery, you can choose to connect the vas deferens with a syringe, and then inject into the uterine cavity of the sow saline with a concentration of 1%, 3%, and a temperature of 36-38 ℃, until salt water flows out of the sow, and then oxytocin can be used.

(2) the contents of the uterus of the sow can be excreted smoothly within 1 day after parturition, but when the cervix of the sow is not fully opened, the pelvis is narrow and the birth canal is obstructed, oxytocin should not be injected within 5 days after parturition. 3-4 sticks of penicillin and streptomycin need to be injected intramuscularly every day to avoid inflammation of the reproductive tract of sows.

2. the method of inducing labor of live fetus.

The main results are as follows: (1) at the beginning, Sodium Chloroprostol Sodium injection 0.1-0.2mg can be injected into the muscle of sows, and drugs can be used to induce labor after confirming the birth of the first fetus.

(2) however, when the cervix of the sow is not fully opened, the pelvis is narrow and the birth canal is obstructed, oxytocin should not be injected. Oxytocin is the first choice. It is recommended to inject 30-50 international units of oxytocin intramuscularly or subcutaneously every 20-30 minutes.

(3) in order to improve the efficacy of oxytocin, estrogen can be used selectively, that is, estradiol 50-100mg is injected intramuscularly before oxytocin is used.

2. matters needing attention in the induction of parturition in sows

1. Dystocia caused by too large fetus and narrow birth canal

When the fetus is too large or the birth canal of the sow is narrow, which makes it difficult for the fetus to pass through the pelvis smoothly, it is generally common in the first-born sow. During midwifery, if the birth canal is relatively dry, the liquid paraffin can be poured into the birth canal, and then put your hand in and drag out the fetal pig.

To induce labor gently, and need to do a good job of hygiene and disinfection, can use warm water and germicidal soap to wash hands and arms, wear disinfection gloves, clean sow door and so on.

2. Dystocia caused by abnormal fetal position

(1) for dystocia caused by incorrect fetal position, the hand can be extended into the birth canal to correct the fetal position for midwifery, the normal fetal position is head-to-vagina abdomen down, and the two limbs stretch forward to clamp the head, as if in a jumping position, instruments need to be used to assist delivery in special cases.

(2) but pay special attention to, if the piglets still have signs of life, try not to use this way, the equipment will hurt or tear the piglets, need to be very patient, not too hard, easy to damage the birth canal of sows.
