Raising pigs like this in winter can greatly improve the survival rate of piglets.

Cold weather is also a challenge for pig farmers, because if the weather is too cold, it will affect the reproduction rate of sows, and the low temperature will also affect the survival rate of piglets. Therefore, at this time, we should pay attention to certain heat preservation measures.

First, build a shed

When the weather is colder, you can build another shed on top of the pigsty, because the heat runs up. Usually, the heat in the pigsty will be emitted from above, and if you build another shed, it will play a proper blocking role, so that you can keep warm.

If you build a shed, you can just use the plank directly, there is no need to have how good-looking, the most important thing is to be practical, after the construction can be properly coated with some asphalt, this has the role of anticorrosion.

Second, laying grass

Many pig houses are covered with cement floor, which of course feels very cool in summer, but very cold in winter. Especially for pregnant sows, such words are very exciting, so we must pay attention to laying the groundwork. For example, laying grass is very good, this can not only make the pig lie on it more warm.

In addition, it has the effect of absorbing moisture. In addition, it is OK to lay some boards in the place where the pigs rest. Sprinkle some feed on the boards, and the pigs will lie down and not defecate on them.

Third, increase density

In winter, you can actually increase the density of raising pigs, in fact, it can also have a warm effect, because if you squeeze together, it will be relatively warm, and in this way, the area for pig activity is relatively small. lying there when you are full is also good for gaining weight.

Some pig pens are divided into two columns, for example, the inner column is dedicated to lying down, and then the outer column is excretion, plus food. If it is designed in this way, then you can drive more pigs into the column that lies inside, and you don't need any room for movement, but you can have a little room for activity in the column that eats outside.

4. Heat preservation of piglets

For newborn piglets, they must need special care. When it is so cold in winter, it is best to prepare a special incubator with a temperature of 30 °, so that the piglets can grow well.

V. ventilation

The best way to reduce the humidity and improve the air of the pig house is ventilation, and the most effective measure of ventilation is to open a ventilation hole on the ceiling. Without opening the doors and windows, a large amount of moisture and bad gases can be discharged from the house as soon as possible and replaced with fresh air. But ventilation should be controlled, more ventilation in sunny and warm days, less ventilation in cloudy and cold days, so as to coordinate ventilation and heat preservation.

Pay attention to details

In autumn and winter, the temperature difference between day and night is large, and the climate turns cold, which is the season with high incidence of disease. Especially the wet and cold cement ground will not only greatly increase the incidence of pigs, but also reduce the feed reward of pigs.

We should establish the concept of effective temperature, we often ignore some factors that affect the effective temperature, such as the influence of thief wind and the influence of wet cement ground.
