Several main causes of abortion in sows

Miscarriage of sows in breeding is an important direction of prevention. There are many factors causing miscarriage at this stage, and some details that have been ignored may lead to it. The main causes of abortion are disease, stress and so on. Let's learn about these reasons together.

1. Sow disease

Sows will also get some reproductive diseases during pregnancy, some before pregnancy, the harm of these diseases is not highlighted at first, and then the disease is very serious. One of the representatives of this disease is hysteritis, which is not detected in time due to improper management, and then during the pregnancy of sows, the fertilized eggs or molded embryos of sows will be threatened and disappear directly over a long period of time. There was a miscarriage.

2. Improper gregariousness

Sows choose to socialize after pregnancy in order to facilitate management or prevent other pigs from harming them, but what is not known is that miscarriages caused by improper gregariousness are very common. A new environment will allow sows to take the time to confirm, especially when some sows are raised together, because of new partners, these sows may struggle and even catch up with each other in the process. In this case, the probability of miscarriage will naturally become higher.

3. Stress

Stress is often encountered in pigs, and it is even more likely for sows. Vaccines, feed changes, and environmental changes are all possible, while sows are fed with nutritional supplements or injected with drugs that are beneficial to production, which can lead to stress. Normal pigs may die under stress, while sows may do more harm. Miscarriages caused by this condition tend to have a longer impact on sows.

4. Sudden change of weather

Sows will become more delicate during pregnancy, become extremely sensitive to the external environment, and in order to ensure the dry condition of sow breeding sites, general ventilation and lighting will be done better. Sudden changes in the weather will bring changes in light, temperature and so on, especially in terms of temperature, if a sudden drop in temperature is very harmful to the sow, the sow pays attention to the constant temperature at this stage. The occurrence of anxiety in sows due to weather factors leads to a series of conditions that eventually lead to miscarriage, which is generally common in areas with unstable weather.

These are the reasons for the miscarriage of sows. A pig gives birth to a lot of piglets, and each miscarriage means a big loss. We should take precautions against some things in this respect, and don't let yourself regret it.
