When the weather gets cold, when will the pigs buckle the plastic?

Generally, when the weather gets cooler, you can fasten the plastic sheeting. Because the temperature is low in winter, pig houses must take measures to keep warm. In addition to these measures, you must also pay attention to keeping the ground dry, maintaining proper ventilation, and drinking water. The temperature should also be increased appropriately.

1 Increase the temperature of the pig house

First, the open pig house is covered with plastic film. It is best to cover with double-layer plastic film. Although the cost is higher than that of single-layer plastic film, the thermal insulation effect is better. This method is suitable for fattening pig houses and non-lactating sow houses. Second, the closed pig-raising workshop implements boiler-type heating. The third is to heat the open pig house and cover it with plastic film. The fourth is heating and electric heaters, which are suitable for lactating sow houses.

2 The peripheral walls should be thick and tight

Insulation facilities should be added to the back wall, gable wall and front wall of the pig house in winter. Crop straws can be stacked and mud bricks can be temporarily built. It is best to thicken the four outer walls of the pig house when it is first built.

3 The ground should be dry

Feces and sewage should be removed in time and cleaned. In order to facilitate drying, the pig house should be made of cement floor.

4 Add bed boards

In the piglet stage, where conditions permit, it is best to use warm bed boards such as wooden boards, bamboo boards, and thickened fiber boards. If conditions fail, cement prefabricated boards can be laid. .

5 Increase the temperature of drinking water

If conditions permit, you can boil cold water into warm water before letting pigs drink it, or pump deep groundwater to feed pigs.

6 The purpose of increasing the number of feedings is to relatively increase feed intake to fill the weight deficit caused by pig body fat and intramuscular metabolic heat production due to low temperature. Where conditions permit, it is best to feed freely. In places where feeding is scheduled, one feeding can be added at night.

7 Improve the feed energy level

It can be increased by about 10% based on the original feed energy level. Big pigs are low, little pigs are high. For small pigs, high-energy feeds such as oils and fats can be added, while for large pigs, the amount of common energy feeds such as corn can be increased in the compound.

8 Increase the lighting area of ??the pig house

The open pig house should have a larger open area in case it is covered with plastic film to facilitate lighting in winter. Closed pig houses should reserve windows on the south wall and roof to prepare for the installation of glass in winter.
