What is the cause of stillbirth in sows?

In pig farms, there is often a phenomenon that piglets produced by sows will die, so what is the reason for this? Are there any obvious symptoms before this phenomenon? How can we prevent this phenomenon when we breed it? Today, the editor will give you a simple analysis, as much as possible to reduce losses in the later stage of breeding.

1. Causes of stillbirth in sows

The causes of stillbirth in sows are very serious and relatively complex. For example, sows are likely to give birth to stillbirths due to premature birth, high temperature in the delivery room, lack of nutrition and long-term limit, drug abuse and herding. Secondly, to analyze in detail, such as feeding deteriorated feed, not cleaning and disinfecting farm hygiene and feed trough hygiene, inadequate vaccination, shock or stress reactions caused by heat, cold and other factors. There are also the effects of some diseases on sows, such as blue ear disease, viral disease, porcine chlamydia trachomatis, leptospirosis, porcine pseudorabies and other diseases, which may cause stillbirth.

2. What are the symptoms before giving birth to a stillbirth?

To be honest, there are no special symptoms before sows give birth to stillbirths, and generally, when you understand that sows give birth to stillbirths, they basically wait until the sows give birth. However, stillbirths in sows generally have two symptoms, namely, premature delivery and stillbirth. Preterm delivery is the same as normal birth, but the physique of the piglets is very weak, and some piglets may be dead. The stillborn fetus will be produced together with the placenta, and the stillborn fetus can be divided into four forms: fetal death, fetal corpse, fetal immersion and fetal putrefaction emphysema.

3. Preventive measures

For this phenomenon of stillbirth in sows, in fact, the most important thing is to take preventive measures, because the later remedy is actually not very effective. Then we need to protect sows from the causes of stillbirth in sows. Generally speaking, the first thing is to raise and manage reasonably, reduce stress reaction, avoid accidents such as overcrowding and impact of sows, and put the sanitary management of farms in place to reduce the incidence of diseases. Finally, it is also necessary to do a good job in vaccine prevention and timely vaccination in accordance with the scientific immunization process.

4. Prevention and control methods

Yimuhongtang is given to sows after parturition to avoid vaginitis; secondly, penicillin, streptomycin and aminopyrine are injected into sows during breeding to avoid bacterial infection; and vasopressin or oxytocin injection is injected to induce labor. When taking a dead fetus by caesarean section, we should apply appropriate amount of iodine when stitching up the wound, and put 2 million-3 million units of chlortetracycline or oxytetracycline capsules into the womb of sows; in order to avoid infection in sows, we also need scientific injection of antibiotics, or penicillin, streptomycin, etc.; finally, 40 milligrams of chlortetracycline or oxytetracycline can be injected daily, and sulfadiazine sodium is injected twice a day.

That's all the editor is going to introduce to you today. In fact, stillbirth of sows occurs not only in large-scale breeding, but also in bulk farmers, so we need to pay attention to it in the later stage of breeding. Hope to see this article, after the breeding process will be more and more smooth, but also hope to help more friends in need.
