How much oxytocin should be given to a 300-jin sow?

For a 300-jin sow, an injection of 3 ml of oxytocin is about right. It must be a small dose to stimulate rhythmic uterine contractions without causing paralysis and similar effects. Generally, 20 to 30 minutes after the injection, the piglets can be delivered. If no piglets appear after the injection, the piglets can be removed manually.

In which situations should oxytocin not be used?

1. When the cervix has not yet opened, oxytocin cannot be used to assist farrowing in this situation.

2. If the sow was mated too early, dystocia caused by a pelvis that is too small during the first farrowing should not be treated with oxytocin.

3. When dystocia is caused by a piglet that is too large blocking the birth canal, oxytocin cannot be used to assist farrowing in this situation.

4. If the fetal position is abnormal during farrowing, oxytocin should not be used; the sow can be made to stand up and change position, which helps correct the fetal position.

5. If the sow can farrow normally, it is best not to use oxytocin, so as to avoid dependence.

6. If the sow's due date is delayed by a few days, oxytocin cannot be used for induced farrowing; cloprostenol is recommended.

The above is the relevant introduction on how much oxytocin to give a 300-jin sow. We hope it is helpful to everyone.
