Detailed Explanation of Key Technical Points for Cold-Resistant Pig Farming

Cold-resistant pig farming techniques are mainly used to reduce the adverse effects of disastrous weather such as heavy rain and freezing, and to aid recovery after disasters.
Main technical contents:
1. Strengthen cold protection and warmth. The sow farrowing room and piglet nursery are the key areas for cold protection and warmth. For enclosed pig houses, use plastic film, foam boards, old packaging bags and other materials to seal the north-facing windows to prevent cold wind from entering the pig house; the south-facing windows should also be sealed, but some ventilation holes should be left; for open-style pig houses, plastic film can be used to seal the open sections, especially the north side of the pig house, which must be sealed. When the sun is out during the day, the south-facing windows should be properly opened for ventilation.
2. Provide additional heat sources for suckling piglets. By lighting coal stoves for heating (but a chimney must be installed), hanging far-infrared lamps, and other methods, provide additional heat sources for newborn suckling piglets and newly weaned piglets.
3. Appropriately increase feed energy. Under heavy snow and severe cold conditions, the energy and feed requirements of pigs increase significantly. In severe cold weather, increase feed by 1 kg per day per pregnant sow; for other pigs (piglets, finishing pigs, lactating sows), do not restrict feed intake and feed them freely. Energy feed such as corn, wheat and brown rice can also be increased by 10-15% on the original basis.
4. Strengthen feeding management. In particular, strengthen the management of suckling piglets, with the focus on preventing suckling piglets from freezing stiff or freezing to death, ensuring that suckling piglets get good colostrum, and strengthening supplementary feeding for suckling piglets; strengthen the removal of manure and urine from pig houses, do not allow pig manure and urine to remain in the pig house, and control the concentration of harmful gases so that they do not exceed standards.
5. Do a good job in epidemic prevention. In severe cold seasons, the possibility of outbreaks of certain viral diseases increases. Pig farms should strengthen immunization work. It is necessary to strengthen the prevention and control of diseases such as transmissible gastroenteritis, epidemic diarrhea and foot-and-mouth disease. At the same time, strengthen disinfection and isolation work, and strictly prevent infectious diseases from entering pig farms.
