What causes sows to give birth to stillborn piglets?

In pig farms, a certain phenomenon often occurs first, namely that the piglets born to sows may be stillborn. So what factors cause this? Are there any obvious symptoms before this phenomenon occurs? How should we prevent this phenomenon during breeding? Today, the editor will give everyone a simple analysis, so as to help everyone reduce losses as much as possible in later breeding.

1. Causes of stillbirth in sows

There are many and relatively complex causes of stillbirth in sows. For example, promoting fetal growth too early in sows, excessively high farrowing house temperature, insufficient nutritional intake, long-term confinement, misuse of drugs, and group transfer can all cause sows to give birth to stillborn piglets. Then, analyzing in more detail, factors such as feeding spoiled feed, failure to clean and disinfect the farm sanitation and feed trough sanitation, inadequate vaccination, stress reactions caused by fright or heat and cold, and so on. There are also the effects of some diseases on sows, such as porcine reproductive and respiratory syndrome, viral diseases, porcine chlamydiosis, leptospirosis, pseudorabies, and other diseases. All of these may cause stillbirth.

2. What symptoms appear before stillbirth?

To be honest, there are no particularly special symptoms before a sow gives birth to stillborn piglets, and generally when we learn that a sow has given birth to stillborn piglets, it is basically already around the time the sow is about to farrow. However, stillbirth in sows generally has two symptoms, namely premature birth and stillbirth. Premature birth is the same as normal birth, but the piglets born are very weak in constitution, and some piglets may also be stillborn. Stillbirths, on the other hand, are delivered together with the fetal membranes. Stillbirths are also divided into four forms: fetal death, mummified fetus, macerated fetus, and putrefied emphysematous fetus.

3. Preventive measures

For the phenomenon of stillbirth in sows, the most important thing is actually to do a good job of prevention, because later remedies are actually not of much use. So we need to start from the causes of stillbirth in sows and protect the sows. Generally speaking, the first thing is reasonable feeding management, reducing stress reactions, avoiding accidents such as crowding and collisions among sows, and doing a good job in the sanitation management of the farm to reduce the incidence of disease. Finally, it is also necessary to do a good job in vaccine prevention and carry out vaccination in a timely manner according to scientific immunization procedures.

4. Prevention and treatment methods

After farrowing, give the sow Yimu brown sugar soup to avoid vaginitis; secondly, during mating, inject the sow with penicillin, streptomycin, and aminopyrine to avoid bacterial infection; also inject posterior pituitary hormone or oxytocin injection to induce labor; when using cesarean section to remove stillborn piglets, when suturing the wound we should apply an appropriate amount of iodine tincture, and put 2 million to 3 million units of chlortetracycline or oxytetracycline capsules into the sow's uterus; in order to prevent the sow from being infected, it is also necessary to scientifically inject antibiotics, or penicillin, streptomycin, and the like; finally, 40 mg of chlortetracycline or oxytetracycline can also be injected daily, and sulfadiazine sodium should be injected twice a day.

The above is all the content the editor wants to introduce to everyone today. Stillbirth in sows actually not only occurs in large-scale breeding, but also often occurs among free-range households, so everyone needs to pay attention during later breeding. I hope friends who see this article will become more and more successful in their later breeding, and I also hope it can help more friends in need.
