Analysis of Several Main Causes of Sow Miscarriage

Miscarriage in sows is an important area of prevention during breeding. There are many factors that can cause miscarriage at this stage, and some details that are easily overlooked can also lead to it. The main causes of miscarriage include disease, stress and other conditions. Let's take a look at these causes together below!

1. Sow diseases

Sows can also contract some reproductive diseases during pregnancy, and some are contracted before pregnancy. The harm of these diseases does not stand out at first, but once they flare up later, the problems become very serious. One representative of this kind of disease is metritis. Due to improper management, the condition is not discovered in time, and then during the sow's gestation period, the sow's fertilized eggs or formed embryos are threatened, and over time they are simply lost, resulting in miscarriage.

2. Improper grouping

After a sow becomes pregnant, it may be grouped with others for easier management or to prevent other pigs from harming the sow, but what people do not know is that miscarriage caused by improper grouping is very common. A new environment makes the sow spend time confirming things, especially when several sows are raised together. Because there are new companions, these sows may fight during this process, and may even chase each other, so under such circumstances the probability of miscarriage naturally becomes higher.

3. Stress

Stress is a common situation encountered in pig farming, and for sows the probability of it occurring is even higher. Vaccines, changing feed and changing the environment can all cause it, and during pregnancy sows are fed some substances to supplement nutrition or injected with drugs that benefit farrowing, all of which can lead to stress. Normal pigs may die from a stress response, and when it occurs in sows the harm is even greater. Miscarriage caused by this situation often has a longer-lasting impact on the sow.

4. Sudden weather changes

During pregnancy, sows become more delicate and extremely sensitive to the external environment, and in order to ensure the dryness of the sow breeding site, ventilation and lighting are generally done relatively well. Sudden weather changes bring changes in light, temperature and so on, especially in terms of temperature. If the temperature drops abruptly, the harm to the sow is very great; at this stage the sow requires constant temperature. Weather factors cause the sow to become restless, then trigger a series of conditions, and finally lead to miscarriage. This is generally more common in areas with unstable weather.

The above are several causes of sow miscarriage. A pig gives birth to quite a few piglets, and each miscarriage means a major loss. Preventive measures should be taken against these issues so that you do not end up regretting it.
