What to Do If a Sow Retains the Placenta? A Detailed Guide to Scientific Handling

You may appropriately inject drugs such as diethylstilbestrol to dilate the sow's uterus, and inject an appropriate amount of oxytocin every half hour to promote the expulsion of the placenta. After about 3 injections, the placenta can be completely expelled. After the placenta is expelled, pay attention to injecting penicillin into the sow's birth canal to disinfect and contract the uterus, preventing infection and illness.

How to care for a sow after farrowing?

1. Placenta check

The first thing we should do after a sow farrows is to check the sow's placenta. Mainly observe whether the number of placentas is the same as the number of piglets born. If the placenta is retained or insufficient, then appropriately inject drugs such as diethylstilbestrol. Dilate the sow's uterus, then inject an appropriate amount of oxytocin every half hour to promote the expulsion of the placenta; after about 3 injections, the placenta can be completely expelled. Then, after the placenta is expelled, pay attention to injecting penicillin into the sow's birth canal to disinfect and contract the uterus, preventing infection and illness.

2. Timely anti-inflammatory treatment

Sows giving birth for the first time may experience difficult labor because the fetuses are too large or too numerous. Therefore, the sow's uterus is very prone to injury, so be sure to do a good job of anti-inflammatory treatment, with about one week as a course of treatment. Penicillin is the main drug, injected about twice a day, then inject warm potassium permanganate and other drugs into the sow's birth canal until the sow's vitality recovers. If about 7 days after anti-inflammatory treatment the sow still has a purulent discharge, then increase the dosage and use drugs such as streptomycin and dexamethasone phosphate. You can also mix Chinese herbal medicine into the feed for feeding, and the effect is also relatively good.

3. Strengthen feeding management

A sow consumes a very serious amount of physical strength during farrowing; the sow's strength declines quickly, and symptoms such as thirst appear. So prepare sufficient warm salt water to provide drinking water for the sow. Within 8 hours after the sow farrows, do not feed feed; just feed warm water. Then on the morning of the second day, appropriately feed some liquid food, because the sow is relatively weak after farrowing, and feed is generally difficult to digest, so appropriately increase the feeding amount according to the sow's physical recovery. Then observe the sow's lactation; if lactation is insufficient, then do a good job of feeding the piglets to prevent them from starving to death.

4. Daily management

After the sow farrows, pay attention to doing a good job of cleaning and sanitizing the pigpen, and carry out comprehensive and thorough disinfection of the pigpen. Ensure that the postpartum sow has a good growing environment. And often observe the growth of the sow and piglets; the disease incidence of sows after farrowing is relatively high. If any sow has an abnormal condition, such as listlessness, decreased appetite, etc., promptly find out the specific cause and then take corresponding measures. About 3 days after the sow farrows, let the sow exercise appropriately and receive sunlight to promote the sow's physical recovery and increase milk production.

The above is the relevant introduction on what to do if a sow retains the placenta. I hope it is helpful to everyone.
