Farmers disperse pigs generally according to the mode of housing, according to local conditions, because of the simplicity, the arches, ridges, umbrellas or single-slope sunny sheds above the sheds. On the south side, an active ventilation window is reserved for temperature adjustment and ventilation. The plastic sheds can be heated and heated to a temperature of 7°C, which is conducive to pig growth and weight gain.
4 Raising the grass bed In the winter, 15 cm thick corn leaves or other hay should be placed on the pig bed, which can absorb moisture, remove moisture and absorb harmful gases, and increase pig bed temperature. It has been proved that 10 cm thick sawdust is placed in the pigsty and the starter is added. After a few days, sawdust starts to ferment. The temperature can reach 35°C and the temperature in the house can be increased. Sawdust washers are good quality fertilizers for crops.
5 Let the pig sleep warmly and dig a 50-cm deep flat earth pit with a layer of soft grass on it. Cover it with straw to allow the piglets to warm up inside; or use a straw shed to stack soft hay on the inside. Drill inside to keep warm.

9 Increased Breeding Density In the winter, the number of pigs in the house can be increased by 1/3 to 1/2 as usual, allowing the pigs to warm up to each other's body temperature. Combined with the heat dissipation of the pigs, the temperature can be increased. Pigs entering new pigs should be carried out on dark days.

The window hole, timely repair of the roof and the four walls of the gap, the pigs' windows and ventilation holes should be 1.0 to 1.5 meters above the ground in order to maintain a relatively stable temperature.
