Livestock pig

1. Raise the temperature of the pig house, pay attention to the cold protection and keep warm to raise the temperature of the pig house, keeping warm is a very important part of winter.

There are many ways to raise the temperature of the pig house, but there are four simple, economical and practical ways. First, the open pig house is covered with plastic film. It is best to cover double-layer plastic film, which is suitable for fat pig houses and non-lactating sows. The second is to implement boiler heating in the closed pig workshop. Third, the open pig house heating and plastic film cover. Fourth, heating and electric heater, which is suitable for lactation sow house. In addition, for newborn pigs, heating equipment should be used to keep the delivery room temperature at 22 ℃-25 ℃. At the same time, heating equipment such as pig electric hot plate and infrared light bulb should be selected to provide heat source for pig incubator (the incubator temperature should be kept at 33 ℃-35 ℃). However, it should be noted that when using coal as fuel heating equipment, we should pay attention to whether the coal combustion is sufficient, whether the flue is unobstructed, to avoid carbon monoxide poisoning in pigs.

2. Keep the house clean, dry and fresh.

Under the premise of maintaining the temperature, strengthen the ventilation, reduce the humidity in the house, wash the fence house with less water as much as possible, clean the feces frequently, maintain a good sanitary environment, reduce the concentration of harmful gases, and keep the air fresh as much as possible. Strengthen the management of cushion materials, cushion materials should be diligently padded, and should be replaced in time when dampness and stench are strong.

3. Closed pig pens to prevent "passing through the hall wind" and "thief wind".

Seal the windows of the pig house, open the door of the pig house as little as possible, and carry out a ceiling on the pig house conditionally to prevent cold air from entering the pig house.

4. Feed reasonably and strengthen nutrition.

Pay attention to the preservation of feed, do not feed moldy and deteriorated feed to prevent poisoning of pigs or miscarriage of pregnant sows. Do a good job of iron supplement, selenium supplement, water supplement, feed supplement and weaning feed for piglets.

5. Increase the feeding density appropriately

When the feeding density is high, the area of each pig is reduced, and each pig can be considerate to keep warm when lying down. At the same time, when the pig feeding density is high, the heat dissipation of their body also increases, which is beneficial to increase the temperature in the house.

6. Improve the environmental hygiene around the pig farm.

Disinfect regularly to kill pathogens in the environment. For sick pigs, symptomatic treatment should be carried out on the premise of doing a good job of heat preservation.
