Eight wonderful ways to raise pigs in winter

1. To raise the temperature of the pig house, one is that the open pig house is covered with plastic film. It is best to cover double-layer plastic film, although the cost is higher than single-layer plastic film, but the heat preservation effect is better. This method is suitable for fattening pig houses and non-lactating sow houses. 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. two。 The outer walls should be thick and tight. The back wall, gable and front wall of the pig house should be increased with thermal insulation facilities in winter. Crop straw can be stacked and mud adobe can be laid temporarily. It is best to thicken the four outer walls when the piggery is first built. 3. The ground should be dry, feces and sewage should be removed and cleaned in time. In order to facilitate drying, the pigsty should be made into cement floor. 4. Add bed board in piggy stage, where there are conditions, it is best to use warm bed boards such as wood, bamboo board and thickened fibreboard, and there are no conditions for laying cement precast boards. 5. Don't let the pig drink cold water. Boil the cold water into warm water and then let the pig drink. 6. The purpose of increasing feeding times is to relatively increase feed intake in order to fill the weight deficit caused by fat and intramuscular metabolic heat production in pigs caused by low temperature. Where there are conditions, it is best to eat freely. In the place of regular feeding, one more feed can be added in the evening. 7. The improvement of feed energy level can increase by about 10% on the basis of the original feed energy level. The big pig is lower and the little pig is higher. Piglets can add fat high-energy feed, and big pigs can increase the quantity of common energy feed such as corn in the formula. 8. To increase the daylighting area of the pig house, the open pig house should have a larger open area in order to cover the plastic film in winter to facilitate daylighting. The enclosed piggery should reserve windows on the south wall and roof for the installation of glass in winter. Author: Liang Jiumei-if ventilation is added, the post is more perfect.
