First, the conditions of the pig
1. The site of the pig house should be high, dry, and sunny. It is necessary to plug the window holes on the north, west, and east sides and repair the roof and the gaps on the four walls in time. The window and ventilation holes of the pig house should be 1-1.5 meters from the ground, and can adjust the size of the hole to keep the temperature stable. 2. The piggery floor should be drained of the faecal sewage in time and cleaned. In order to facilitate drying, the piggery should be made of concrete floor.
3, the whole door and window of the pig house should be covered with plastic cloth to keep it warm and cold. In the windward direction, use straw or corn stalks to form wind barriers or windrows to prevent wind from invading the shed. 4, increase the lighting area of ​​pigs. When the pig house is built, it is necessary to consider the lighting area of ​​the pig house. The open-type pig house should have a large open area in order to prepare the winter covered plastic film for easy lighting. Closed pig houses are to be reserved in the south wall and the roof to prepare for the installation of glass in winter. Second, increase the temperature
Set up a heat source in the pig house to increase the temperature in the pig house. Hot air heaters, heaters, coal stoves and other equipment can be used to provide heat. Additional heating sources for the pig incubator can be provided by heating equipment such as hot plates and infrared light bulbs. In the use of coal-fired heating equipment, attention should be paid to the smoothness of the flue to avoid carbon monoxide poisoning in pigs due to poor smoke and carbon monoxide detention. At the same time, measures must be taken to prevent fire. Third, feeding and management
1. Do not allow the pig to drink cold water. Warm the cold water and let the pigs drink it.
2, moderately increase the energy level in the feed, can be increased by about 10% on the basis of the original feed energy level. The big pigs are low and the pigs are high. Piglets can be supplemented with high-energy feeds for fats and oils. Big pigs can increase the amount of common energy feeds such as corn in batches.
3, appropriate increase in feeding density. When the breeding density is high, each pig's floor space is reduced, and when lying down, it can be warmly attached to each other. At the same time, when the pigs are kept at high density, their body heat is also increased, which is conducive to raising the temperature inside the house.
