Detailed Explanation of Cold Protection and Warming Methods for Winter Piglets

The suitable temperature for piglet growth is: 34-30°C at 1-3 days of age, 30-28°C at 4-7 days of age, and 25-22°C at 15-30 days of age. Winter temperatures are low, so the following cold protection and warming measures should be taken for piglets.

1. The pen should be prepared for cold protection and insulation before winter, repair doors and windows in time, and fill in drafty holes and gaps. For open-style farmer pig pens, windbreak cloth curtains sewn from woven fabric or feed woven bags should be used to block the windward positions, minimizing ventilation as much as possible and preventing north wind and rain from directly penetrating from outside, so as to raise the temperature of the pig pen.

2. When the sow is about to give birth, dedicated personnel should be on duty for farrowing. As soon as each piglet is born, wipe off the mucus on its body, place it in an insulated pen or a basket with insulation materials such as straw, cover it with a hemp sack for warmth, and regularly return it to the sow for nursing. After feeding, return it to the warm area. Only after 2-3 days should the piglets be allowed to stay by the sow's side to suckle milk.

This avoids piglets being accidentally crushed to death when the sow turns over or lies down because the piglets stay close to the sow for warmth. If conditions permit, it is best to set up an insulated pen in the enclosure, equipped with a 250-watt infrared warming lamp or an insulated heating pad, with piglets free to enter and exit. This has a better cold protection and warming effect for piglets.

3. Strengthen feed supply, and feed the sow high-quality, easily digestible, and sufficient feed so that the sow has abundant milk and the piglets eat their fill. In addition, increase supplementary feeding, and feed piglets high-quality creep feed and suckling pig feed early, so that in addition to breast milk, piglets can promptly supplement other nutrients, thereby improving the piglets' digestive and absorptive function, increasing disease resistance and cold resistance, and enabling the piglets to grow healthily.

4. Do a good job of epidemic prevention and immunization in a timely manner. For common diseases such as pseudorabies, colibacillosis, swine fever, foot-and-mouth disease, epidemic diarrhea, and transmissible gastroenteritis, immunization injections should be carried out on time and in the correct dosage according to the immunization program, as well as routine disinfection work. Spray disinfectant drugs such as Baidusha, Jundudi, phenols, and hydrogen peroxide twice a week to prevent and reduce the occurrence of diseases.
