The suitable temperature for raising pigs in winter

As time went by, winter gradually entered. Pig farmers have also begun to prepare pigs for winter work, winter temperatures are very low. If you do not do a good job of management, then pigs in winter easily catch a cold, affecting fat gain and so on. Therefore, the management of pigs in winter is very important, especially the temperature. So what is the temperature suitable for raising pigs in winter? How to regulate the temperature? Let's take a look at it together with Xiaobian below!

1. Suitable temperature for pigsty in winter

China's winter temperature is generally relatively low, the temperature outside the house decreases, and the temperature inside the house naturally decreases. Low temperature environment is a serious threat to the growth of pigs. It will reduce the physiological functions of pigs, and the impact on piglets will be greater, such as diarrhea and other undesirable phenomena, and the survival rate will decrease. In winter, the temperature suitable for pig growth is about 15-22 degrees, and the minimum temperature cannot be lower than 8 degrees. As temperatures drop, pigs need more feed to maintain their body temperature, which reduces feed conversion and results in lower farming efficiency.

II. Key points of pigsty management in winter

1. Anti-theft wind

Thief wind is the main cause of temperature drop in pigsty in winter. Thief wind invasion will lead to various stress reactions in pigs, such as cold, pneumonia and other diseases. Therefore, in winter, we must ensure that the walls around the pigsty are tightly ventilated, and comprehensive inspection and maintenance work should be carried out on the pigsty. Avoid gaps in doors and windows, vents, holes, etc. that cause thieves to enter the pigsty. Especially for the old pigsty with the service life, it must be thoroughly inspected and repaired. Some crop straws can be piled outside the wall, and soil walls can be piled up. In winter, the ventilation opening of pigsty should be kept at least one meter above, so as to avoid blowing directly onto pigs during ventilation.

2, enhance the light

The natural lighting time in winter is relatively short, but professional research data show that reasonable enhancement of light intensity in winter can effectively improve the reproductive capacity of pigs. It can gain weight by about 1/10 every day, and it can also effectively reduce the incidence of piglets. Therefore, attention should be paid to improving the lighting rate in the pigsty. When improving the lighting rate, we should pay attention to the requirements of the whole pig herd for light. It is best to be able to set up a lighting area, in the top of the injection and the south wall to retain a lighting opening, can be used for lighting in winter. And in sunny afternoons, pigs can be allowed to exercise outdoors properly, allowing them to receive sunlight.

3. Control humidity

Pigs are suitable for growing in a dry environment. In winter, piggery should pay attention to maintaining a dry environment with low humidity. The higher the air humidity, the lower the temperature of the pigsty, the faster the heat loss in the pig body, which is very unfavorable to the growth of pigs and easily leads to the death of pigs. Moreover, if the humidity is too high, it is very conducive to the reproduction of pathogens, which is easy to cause various diseases, such as respiratory diseases, skin diseases, etc. Therefore, we need to regulate the humidity of pigsty by managing the feeding and rest of pigs, cleaning feces and regularly changing the bedding in winter. If the humidity is too high, then some lime and plant ash can be sprinkled in the pigsty to reduce the humidity.

The above is a brief introduction to the temperature suitable for pigs in winter. Today's introduction is here. This article is for reference only. I hope it can help everyone.
